Flickering Textures

1) Create a Javascript File

2) Paste in this script.

3) Drag it on the object you want your textures to flicker on. Fill the slots with 2 textures that you want to change.

var texture1 : Texture2D; var texture2 : Texture2D; var change : boolean = true; function Start() { changeTexture(); } function Update () { } function changeTexture () { while(change) { yield WaitForSeconds(0.1); renderer.material.mainTexture = texture1; yield WaitForSeconds(0.1); renderer.material.mainTexture = texture2; } }

Change Texture on Collision

1) Create an object with a collider (sphere, cube, etc.) and click iS Trigger to on under the inspector.

2) Under inspector make the collider bigger than the object by changing the numbers under size.

3) Create a javascript file and paste this script inside.

var texture1 : Texture2D;

function OnTriggerEnter (other : Collider) { if(other.gameObject.tag == "Player"){ renderer.material.mainTexture = texture1; } }

4) Make sure the player is tagged "Player"

5) Drag this script onto the object you want to change.

#texture #swap on collision #unity #Unity3D

STUFF CANNON!

1. This is a stuff cannon that shoots primative objects.

2. You will need to create a C# script in your library, name it StuffCannon, delete the text in it, and replace it with the code below.

using UnityEngine; using System.Collections; public class StuffCannon : MonoBehaviour { RaycastHit hit; Camera mainCam; int fireTimer = 0; [SerializeField] Material stuffMat; [SerializeField] int fireDelay = 150; [SerializeField] float range = 10f; [SerializeField] PrimitiveType stuffType = PrimitiveType.Cube; [SerializeField] KeyCode fireButton = KeyCode.K; void Start() { mainCam = gameObject.GetComponentInChildren<Camera>(); } void Fire() { if (Physics.Raycast (transform.position, mainCam.transform.forward, out hit, range)) { if (fireTimer >= fireDelay) { GameObject temp = GameObject.CreatePrimitive(stuffType); temp.transform.position = hit.point; temp.transform.parent = gameObject.transform; temp.AddComponent<DestroyAfterDelay>(); temp.AddComponent<Rigidbody>(); temp.renderer.material = stuffMat; } } } void Update() { if (Input.GetKey (fireButton)) { Fire (); fireTimer++; } else { fireTimer = 0; } } }

3. Now make a second C# script, named DestroyAfterDelay. It is VERY important that the script have this name exactly. Paste this code into the script:

using UnityEngine; using System.Collections; public class DestroyAfterDelay : MonoBehaviour { int timer = 90; void Update () { if (timer <= 0) { GameObject.Destroy(gameObject); } timer-=1; } }

4. In Unity, drag the StuffCannon script onto your character controller.

5. Play with the variables in StuffCannon to change the kind of thing fired, the material it uses, the charging delay, and the button that fires (K by default).

Enemy AI (Alert Distance) - Now with yLock Capabilities!

Note: yLock allows you to stop the enemy from chasing you along the y axis

1). This is an enemy AI that activates when the Player comes within a certain distance of it, chasing and shooting at the player.

2). For this script, you need a player tagged as Player, an enemy with isTrigger checked, and a bullet (make sure it has a rigidbody, gravity turned off, isTrigger checked, and the bullet script from here.

3). Drag this script onto the enemy:

var player : Transform;

var distanceToActivate : int = 15;

var rotationSpeed : int = 5;

var moveSpeed : int = 2;

var bullet: Rigidbody;

var timer : int = 0;

var shootTime : int = 40;

var canShoot : boolean = true;

var yLocked : boolean = true;

//var target : Transform; //the enemy’s target

//var moveSpeed = 3; //move speed

//var rotationSpeed = 3; //speed of turning

var myTransform : Transform; //current transform data of this enemy

function Awake()

{

myTransform = transform; //cache transform data for easy access/preformance

}

function Update()

{

if(Vector3.Distance(player.transform.position, transform.position) < distanceToActivate)

{

timer++;

if(yLocked)

{

var newPos = new Vector3(player.position.x, myTransform.position.y, player.position.z);

myTransform.rotation = Quaternion.Slerp(myTransform.rotation,

Quaternion.LookRotation(newPos - myTransform.position), rotationSpeed*Time.deltaTime);

myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;

}

else

{

myTransform.rotation = Quaternion.Slerp(myTransform.rotation,

Quaternion.LookRotation(player.position - myTransform.position), rotationSpeed*Time.deltaTime);

myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;

}

if(timer % shootTime == 0 && canShoot){

timer = 0;

//make bullet clone and set it to whatever it’s on

var getLocation:Number;

var clone :Rigidbody;

clone = Instantiate(bullet, transform.position,transform.rotation);

//give the clone a velocity

clone.velocity = transform.TransformDirection(Vector3.forward*50);

//Get rid of the bullet by putting the bullet destroy script on the prefab

}

4). Drag the character controller into the empty variable slot.

5). Mess with the variables to get the AI to function how you want it. (You can now toggle yLock on and off to stop the enemy from chasing you up and down along the y axis).

EG: if you make the distance to activate big enough he will always follow you, turning canShoot to false will disable all shooting, and making move speed negative will make the AI run from you.

#unity3d #ylock #enemy #AI #alert

Stalker AI with Y Locked

This will make the enemy move on the X and Z axes

Make a script, paste this in.

Make sure everything in quotes is pink if it isn’t retype it and don’t forget the quotes!

then drag it onto the object you want to follow the player. Make sure you set target in the inspector to your Character Controller

var target : Transform; //the enemy’s target

var moveSpeed = 3; //move speed

var rotationSpeed = 3; //speed of turning

var myTransform : Transform; //current transform data of this enemy

function Awake()

{

myTransform = transform; //cache transform data for easy access/preformance

}

function Start()

{

target = GameObject.FindWithTag("Player").transform; //target the player

}

function Update () {

//rotate to look at the player

var newPos = new Vector3(target.position.x, myTransform.position.y, target.position.z);

myTransform.rotation = Quaternion.Slerp(myTransform.rotation,

Quaternion.LookRotation(newPos - myTransform.position), rotationSpeed*Time.deltaTime);

//move towards the player

myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;

}

#enemy #ai #unity3d #ylock

Charging Player Launch Cannon

1). You need an object (Your cannon) with istrigger checked, and a player tagged as player.

2). Place this script on the cannon.

var cannonScript : cannonPlayer;

function OnTriggerEnter(other : Collider)

{

if(other.gameObject.tag == "Player")

{

cannonScript.disable = true;

}

3). place this script on the character controller.

var disable : boolean = false;

var motor : CharacterMotor;

var climbHeight : int=100;

function Awake()

{

gameObject.AddComponent(Rigidbody);

gameObject.rigidbody.useGravity = false;

}

function Update ()

{

print(disable);

if(disable == true)

{

motor.canControl = false;

motor.sliding.enabled = false;

motor.movement.gravity = 0;

motor.movement.velocity = Vector3.zero;

gameObject.rigidbody.velocity += Vector3.down * .4;

if (Input.GetKeyDown ("space"))

{

gameObject.rigidbody.velocity = Vector3.zero;

motor.canControl = true;

motor.sliding.enabled = true;

motor.movement.gravity = 10;

motor.movement.velocity = Vector3.forward * 5;

motor.movement.velocity += motor.jumping.jumpDir * motor.movement.gravity * Time.deltaTime * climbHeight;

disable = false;

}

4). Drag the character controller object into the empty slot for both scripts.

#cannon #springboard #launch #unity3d

Power-Up Script

Drag this script onto an object to turn it into a powerup! Be sure to fill the empty spaces with the character controller and a particle effect that will replace the object when it is collected.

Also, change the jump height multiplier and move speed mult variables to change how the powerup affects the controller

var keyReplacement: GameObject;

var motor : CharacterMotor;

var jumpHeightMult : double = 10;

var moveSpeedMult : double = 2;

function OnTriggerEnter(other : Collider)

{

if(other.gameObject.tag == "Player")

{

motor.movement.maxForwardSpeed *= moveSpeedMult;

motor.movement.maxSidewaysSpeed *= moveSpeedMult;

motor.movement.maxBackwardsSpeed *= moveSpeedMult;

motor.jumping.baseHeight *= jumpHeightMult;

//make the replacement variable show up

var makeKeyReplacement : GameObject;

makeKeyReplacement = Instantiate(keyReplacement, transform.position, transform.rotation);

//destroy the key and replace it with sparks

Destroy(gameObject);

}

#powerup #speedboost #unity3d

Patroling Enemy AI

1). For this tutorial, you need:

A bullet (this is an object with a rigidbody, gravity turned off, Istrigger on, and dragged into the grey space as a prefab... be sure to add the bullet script from here)

An enemy with Istrigger on

2 empty gameObjects (These will be the starting and ending position that the enemy will pace from)

2). Drag this script onto the enemy:

var location1 : Transform;

var location2 : Transform;

var rotationSpeed : int = 5;

var moveSpeed : int = 2;

var bullet: Rigidbody;

private var timer : int = 0;

var shootTime : int = 40;

var canShoot : boolean = true;

private var disableShoot = false;

private var disableTimer = 0;

private var disableTime = 100;

//var target : Transform; //the enemy’s target

//var moveSpeed = 3; //move speed

//var rotationSpeed = 3; //speed of turning

private var currentObjective : Transform; //current transform data of this enemy

private var myTransform : Transform;

function Awake()

{

myTransform = transform; //cache transform data for easy access/preformance

currentObjective = location1;

}

function Update ()

{

if(Vector3.Distance(currentObjective.transform.position, transform.position) < .5)

{

disableShoot = true;

disableTimer = 0;

if(currentObjective == location1)

{

currentObjective = location2;

}

else

{

currentObjective = location1;

}

timer++;

myTransform.rotation = Quaternion.Slerp(myTransform.rotation,

Quaternion.LookRotation(currentObjective.transform.position - myTransform.position), rotationSpeed*Time.deltaTime);

myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;

if(disableShoot && disableTimer < disableTime)

{

disableTimer++;

}

else if(timer % shootTime == 0 && canShoot){

timer = 0;

//make bullet clone and set it to whatever it’s on

var getLocation:Number;

var clone :Rigidbody;

clone = Instantiate(bullet, transform.position,transform.rotation);

//give the clone a velocity

clone.velocity = transform.TransformDirection(Vector3.forward*50);

//Get rid of the bullet by putting the bullet destroy script on the prefab

disableShoot = false;

}

3). Drag the bullet and the two empty game objects into the empty spaces. The game objects go into the location variables and the bullet in the bullet space.

4). Adjust speed as necessary.

#shoot #enemy #AI #patrol #unity3d

Launch/Trampoline Script (AKA BOUNCY BOUNCY)

1). For this script, you need a platform with isTrigger checked and a player tagged as Player.

2). This script goes onto your launch platform

var launchScript : launch;

function OnTriggerEnter(other : Collider)

{

if(other.gameObject.tag == "Player")

{

launchScript.launch = true;

}

3). This script goes onto your character controller (IT MUST BE NAMED "launch")

var launch : boolean = false;

var motor : CharacterMotor;

var launchHeight : int=100;

function Update ()

{

if(launch == true)

{

motor.movement.velocity += motor.jumping.jumpDir * motor.movement.gravity * Time.deltaTime * launchHeight;

launch = false;

}

4). Change the launch height to make your player fly higher and higher!

#launch #trampoline #bouncy #unity3d

Parkour Script!!! (Sticking to walls)

1). you need an box with isTrigger checked and a player tagged as Player.

2). Put this script on the box.

var parkourScript : parkour;

function OnTriggerEnter(other : Collider)

{

if(other.gameObject.tag == "Player")

{

parkourScript.disable = true;

}

3). Put this script on the player... MAKE SURE IT IS NAMED "parkour"

var disable : boolean;

var motor : CharacterMotor;

var climbHeight : int=100;

function Update ()

{

print(disable);

if(disable == true)

{

motor.canControl = false;

motor.sliding.enabled = false;

motor.movement.gravity = 0;

motor.movement.velocity = Vector3.zero;

if (Input.GetKeyDown ("space"))

{

motor.canControl = true;

motor.sliding.enabled = true;

motor.movement.gravity = 10;

motor.movement.velocity = Vector3.forward * 5;

motor.movement.velocity += motor.jumping.jumpDir * motor.movement.gravity * Time.deltaTime * climbHeight;

disable = false;

}

4). Drag the character controller into the empty space on BOTH scripts.

5). Change the climb height to give an extra jump boost when jumping off your new parkour block.

For extra fun, turn off the rendering on your cube! DOUBLE JUMP

#parkour #DOUBLEJUMP #unity3d

Enemy AI (Alert Distance)

1). This is an enemy AI that activates when the Player comes within a certain distance of it, chasing and shooting at the player.

3). Drag this script onto the enemy:

var player : Transform;

var distanceToActivate : int = 15;

var rotationSpeed : int = 5;

var moveSpeed : int = 2;

var bullet: Rigidbody;

var timer : int = 0;

var shootTime : int = 40;

var canShoot : boolean = true;

//var target : Transform; //the enemy’s target

//var moveSpeed = 3; //move speed

//var rotationSpeed = 3; //speed of turning

var myTransform : Transform; //current transform data of this enemy

function Awake()

{

myTransform = transform; //cache transform data for easy access/preformance

}

function Update()

{

if(Vector3.Distance(player.transform.position, transform.position) < distanceToActivate)

{

timer++;

myTransform.rotation = Quaternion.Slerp(myTransform.rotation,

Quaternion.LookRotation(player.position - myTransform.position), rotationSpeed*Time.deltaTime);

myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;

if(timer % shootTime == 0 && canShoot){

timer = 0;

//make bullet clone and set it to whatever it’s on

var getLocation:Number;

var clone :Rigidbody;

clone = Instantiate(bullet, transform.position,transform.rotation);

//give the clone a velocity

clone.velocity = transform.TransformDirection(Vector3.forward*50);

//Get rid of the bullet by putting the bullet destroy script on the prefab

}

4). Drag the character controller into the empty variable slot.

5). Mess with the variables to get the AI to function how you want it.

EG: if you make the distance to activate big enough he will always follow you, turning canShoot to false will disable all shooting, and making move speed negative will make the AI run from you.

#AI #enemy #shoot #unity3d

Enemies Taking Damage (Compatible with Different Bullet Types)

1). First, make sure to follow the Shooting with 3 Different Ammo Tutorial... This is an extension to that tutorial so that you can now kill enemies with the three different bullets, each type dealing different amounts of damage.

2). When you have finished the tutorial, make sure each of your prefab bullets are tagged. They should be tagged as bullet1, bullet2, and bullet3.

Note: You can create custom tags by hitting the tag dropdown menu, hitting Add tag..., clicking the whitespace next to Element (whatever number), and putting the name of the tag.

3). Create an enemy that your player can fight.

4). Drag this script onto the enemy

var health:int;

var bullet1Damage : int;

var bullet2Damage : int;

var bullet3Damage : int;

function OnTriggerEnter(other:Collider){

//This checks to see if the tag is bullet so anything with bullet will kill

if(other.gameObject.tag == "bullet1"){

health-=bullet1Damage;

}

if(other.gameObject.tag == "bullet2"){

health-=bullet2Damage;

}

if(other.gameObject.tag == "bullet3"){

health-=bullet3Damage;

}

function Update () {

if(health <= 0){

//kill if health is done

Destroy(gameObject);

}

5). Change the values for the enemy's health and how much damage he takes from each type of bullet.

#shoot #enemy #damage #tripleshot #unity3d

Simple Object/Enemy Has Health and Dies

1) You must follow any of the shooting scripts here.

2) The bullet must be tagged "bullet" or it will not work.

3) Make sure both the bullet and the object you're killing both have IsTrigger clicked on.

4) Create a new javascript file and paste the script in below. Make sure that anything in quotes is PINK! If it isn't retype the word with the quotes between the brackets:

#pragma strict var health:int; function OnTriggerEnter(other:Collider){ //This checks to see if the tag is bullet so anything with bullet will kill if(other.gameObject.tag == "bullet"){ health-=1; } } function Update () { if(health <= 0){ //kill if health is done Destroy(gameObject); } }

5) Make sure to set the health variable for the number of hits you want it to take before it destroys.

6) Drag the script onto the object you want to destroy.

#health #enemy #object #simple #death #unity3d

Shooting with 3 Different Ammo

1). Objects needed -

3 Bullets (these must be a prefab with a Rigidbody… refer to recent shooting tutorials for details on how to make these)

an empty game object (this will be your GUI object)

Character controller

An Object to Pick Up(you should only have one of these until step 7)

Particle System(this will replace your object with an effect/other object when collected).

2). IsTrigger and tags -

Make sure that your bullets are prefabs with a rigidbody.

Make sure IsTrigger is checked for your bullets and ammo.

Make sure your player is tagged as Player.

3). The scripts - there are three different scripts for this tutorial… MAKE THE FILES THE SAME NAME AS IT'S SPELLED, otherwise this WILL NOT WORK. Caps matter.

Reminder: You will get an error till all the scripts are in!

the “tripleAmmo” script:

var keyReplacement: GameObject;

var GUIScript:tripleShotGUI;

var bulletScript : tripleShot;

var ammoValue = 5;

function OnTriggerEnter (other : Collider) {

if(other.gameObject.tag == "Player"){

bulletScript.numOfBullets1+=ammoValue;

bulletScript.numOfBullets2+=ammoValue;

bulletScript.numOfBullets3+=ammoValue;

//make the replacement variable show up

var makeKeyReplacement : GameObject;

makeKeyReplacement = Instantiate(keyReplacement, transform.position, transform.rotation);

//destroy the key and replace it with sparks

Destroy(gameObject);

}

the "tripleShot" script:

var bullet1: Rigidbody;

var bullet2: Rigidbody;

var bullet3: Rigidbody;

var numOfBullets1 : int;

var numOfBullets2 : int;

var numOfBullets3 : int;

function Update () {

var getLocation:Number;

if(Input.GetButtonDown("Fire1")){

if(numOfBullets1 > 0)

{

//make bullet clone and set it to whatever it’s on

numOfBullets1-=1;

//make bullet clone and set it to whatever it’s on

var clone :Rigidbody;

clone = Instantiate(bullet1, transform.position,transform.rotation);

//give the clone a velocity

clone.velocity = transform.TransformDirection(Vector3.forward*50);

//Get rid of the bullet by putting the bullet destroy script on the prefab

}

if(Input.GetButtonDown("Fire2")){

if(numOfBullets2 > 0)

{

//make bullet clone and set it to whatever it’s on

numOfBullets2-=1;

//make bullet clone and set it to whatever it’s on

var clone2 :Rigidbody;

clone2 = Instantiate(bullet2, transform.position,transform.rotation);

//give the clone a velocity

clone2.velocity = transform.TransformDirection(Vector3.forward*50);

//Get rid of the bullet by putting the bullet destroy script on the prefab

}

if(Input.GetButtonDown("Fire3")){

if(numOfBullets3 > 0)

{

//make bullet clone and set it to whatever it’s on

numOfBullets3-=1;

//make bullet clone and set it to whatever it’s on

var clone3 :Rigidbody;

clone3 = Instantiate(bullet3, transform.position,transform.rotation);

//give the clone a velocity

clone3.velocity = transform.TransformDirection(Vector3.forward*50);

//Get rid of the bullet by putting the bullet destroy script on the prefab

}

the “tripleShotGUI” script:

var bulletScript : tripleShot;

function OnGUI () {

// Make a background box

GUI.Box (Rect (10,10,100,25), "Bullets1: " + bulletScript.numOfBullets1.ToString());

GUI.Box (Rect (10,45,100,25), "Bullets2: " + bulletScript.numOfBullets2.ToString());

GUI.Box (Rect (10,80,100,25), "Bullets3: " + bulletScript.numOfBullets3.ToString());

}

4). Placing the Scripts:

theGUI script goes into your empty game object.

bulletShooter script goes into the main camera INSIDE your character controller.

ammo script goes into your ammo object.

5). Filling in the needed objects for each script:

Drag the main camera inside the character controller into the empty slot for theGUI script.

Drag the particle, the empty game object (your GUI) and the main camera into the ammo script’s empty spots.

Drag your bullets into the bulletShooter script on your main camera.

6). Change the Num of Bullets variable in your main camera to the number of ammo you want at the start, and change the ammo value on your ammo to change how much ammo you get from each ammo pack.

7). You can now copy your ammo as many times as you want.

#tripleshot #ammo #shoot #unity3d

Shooting with Ammo

1). Objects needed:

A Bullet (this must be a prefab with a Rigidbody... refer to recent shooting tutorials for details on how to make this)

Empty Game Object (this will be your GUI object)

Character Controller

1 Object to act as an ammo cartridge (you should only have one of these until step 7)

A Particle System (this will replace your ammo when the ammo is collected).

2). IsTrigger and Tags:

Make sure that you bullet is a prefab with a rigidbody.

Make sure Istrigger is checked for your bullet and ammo.

Make sure your player is tagged as Player.

3). The scripts - there are three different scripts for this tutorial... THE FILE NAMES MUST BE THE SAME AS WRITTEN! Caps matter.

Remember: Caps matter and get all the scripts in don't worry about errors.

the "ammo" script:

var keyReplacement: GameObject;

var GUIScript:theGUI;

var bulletScript : bulletShooter;

var ammoValue = 5;

function OnTriggerEnter (other : Collider) {

if(other.gameObject.tag == "Player"){

bulletScript.numOfBullets+=ammoValue;

//make the replacement variable show up

var makeKeyReplacement : GameObject;

makeKeyReplacement = Instantiate(keyReplacement, transform.position, transform.rotation);

//destroy the key and replace it with sparks

Destroy(gameObject);

}

the bulletShooter script:

var bullet: Rigidbody;

var numOfBullets : int;

function Update () {

var getLocation:Number;

if(Input.GetButtonDown("Fire1")){

if(numOfBullets > 0)

{

//make bullet clone and set it to whatever it’s on

numOfBullets-=1;

var clone :Rigidbody;

clone = Instantiate(bullet, transform.position,transform.rotation);

//give the clone a velocity

clone.velocity = transform.TransformDirection(Vector3.forward*50);

//Get rid of the bullet by putting the bullet destroy script on the prefab

}

the "theGUI" script:

var bulletScript : bulletShooter;

function OnGUI () {

// Make a background box

GUI.Box (Rect (10,10,100,25), "Bullets: " + bulletScript.numOfBullets.ToString());

}

4). Where to put the scripts:

theGUI script goes into your empty game object.

The bulletShooter script goes into the main camera INSIDE your character controller.

The ammo script goes into your ammo object.

5). Filling in the needed objects for each script:

Drag the main camera inside the character controller into the empty slot for the theGUI script.

Drag the particle, the empty game object (your GUI) and the main camera into the ammo script's empty spots.

Drag your bullet into the bulletShooter script on your main camera.

6). Change the Num of Bullets variable in your main camera to the number of bullets you want at the start, and change the ammo value on your ammo to change how much ammo you get from each ammo pack.

7). You can now make as much ammo as you want.

#ammo #shoot #unity3d

Shooting With 3 Different Bullets

***This guide is much like the shooting bullets guide, just with multiple Bullet objects being put into the script (This particular script is for 3 different bullets, one for each mouse button).

First you make three DIFFERENT bullet in the scene, add a Rigidbody to each by going to Components > Rigidbody, and uncheck the use gravity box. Then attach this script to each bullet and make them into prefabs and delete them from the hierarchy(don’t forget to fill the lifespan variable for each bullet type!):

var lifespan : float;

function Awake() {

Destroy(gameObject, lifespan);

}

Then you make this script and attach it to the main camera of the First Person Controller. When it’s attached you drag the three different bullet prefabs FROM THE LIBRARY to the open variable slots in the inspector:

var bullet1: Rigidbody;

var bullet2: Rigidbody;

var bullet3: Rigidbody;

function Update () {

var getLocation:Number;

if(Input.GetButtonDown("Fire1")){

//make bullet clone and set it to whatever it’s on

var clone :Rigidbody;

clone = Instantiate(bullet1, transform.position,transform.rotation);

//give the clone a velocity

clone.velocity = transform.TransformDirection(Vector3.forward*50);

//Get rid of the bullet by putting the bullet destroy script on the prefab

}

if(Input.GetButtonDown("Fire2")){

//make bullet clone and set it to whatever it’s on

var clone2 :Rigidbody;

clone2 = Instantiate(bullet2, transform.position,transform.rotation);

//give the clone a velocity

clone2.velocity = transform.TransformDirection(Vector3.forward*50);

//Get rid of the bullet by putting the bullet destroy script on the prefab

}

if(Input.GetButtonDown("Fire3")){

//make bullet clone and set it to whatever it’s on

var clone3 :Rigidbody;

clone3 = Instantiate(bullet3, transform.position,transform.rotation);

//give the clone a velocity

clone3.velocity = transform.TransformDirection(Vector3.forward*50);

//Get rid of the bullet by putting the bullet destroy script on the prefab

}

#multishot #shoot #unity3d

Timed Object/Enemy Spawner for Unity 3d

First make an empty game object. Then create a Javascript file and use the code below. Don’t forget to drag the enemy game object into the variable slot in the inspector.

Don’t forget to play with the max enemies and the time till spawning variables.

var enemy : GameObject; var nextSpawn:float = 0.0; var spawnInterval:float = 5.0; var maxEnemies:int = 5; var totalEnemies:int = 0; function Start(){ //On the start set the time since the start of the game then add the spawn interval to it. nextSpawn = Time.time + spawnInterval; } function Update(){ //Check if the time is greater than the next spawn time and that the enemies limit hasn't been hit if(Time.time > nextSpawn && totalEnemies < maxEnemies){ nextSpawn = Time.time + spawnInterval; spawnEnemy(); } } function spawnEnemy(){ //set the enemy to appear at the position of the object the script is attached to Instantiate(enemy, transform.position, Quaternion.identity); totalEnemies++; }

#spawner #object #enemy #unity3d
