UnityでFlashのBitmapDataっぽい使い方

RenderTextureをアタッチしたカメラにこんな感じでスクリプトをつけてあげると、AS3のBitmapDataっぽい挙動になる。ぺたぺた描画内容を貼りたいときはDraw()を呼んで、初期化したいときはClear()を呼ぶ。もしかして、、これはすごく便利ではなかろうか・・・！！！！

using UnityEngine; using System.Collections; public class BitmapController : MonoBehaviour { private Camera camera; private RenderTexture rTexture; // Use this for initialization void Start () { camera = gameObject.GetComponent<Camera>(); camera.clearFlags = CameraClearFlags.Nothing; camera.enabled = false; rTexture = camera.targetTexture; Clear (); } public void Draw(){ camera.enabled = true; camera.Render (); camera.enabled = false; } public void Clear(){ RenderTexture.active = rTexture; GL.Clear (false, true, Color.clear); RenderTexture.active = null; } }

HALLELUJAH!!!!!

Implementation

I have finally made the bitmapdata work!! After many discouraging weeks and thoughts of massive failure, I have proved that I am not as bad at this as I thought I was. Although I have asked for A LOT of help from Ben, and stackoverflow, I feel that my persistent testing has lead me to solving this issue.

So how did I do it?

Firstly, I had to declare, ‘this.currentMatCol’ and ‘this.roadMatCol’ at the very top of the game.js file. Then, I had to set ‘roadMatCol’ to black “        this.roadMatCol = new Phaser.Color.createColor(0, 0, 0);” in the Create function. In the update function, I had to use the following two lines code:

“var currentMatCol = bmd.getPixelRGB(Math.round(car1.x), Math.round(car1.y));” - This gets the pixel at x and y of the car as an RGBA value. “var roadMatCol = {r: 0, g: 0, b: 0};” - This sets ‘roadMatCol’ to black.

Next, I had to create an ‘if’ statement to check if ‘currentMatCol’ was equal to ‘roadMatCol’: “if (currentMatCol.r == roadMatCol.r && currentMatCol.g == roadMatCol.g && currentMatCol.b == roadMatCol.b)”

So, if the colours were the same, then the car would handle how it should, I inserted the button actions in here. But if the colours were not the same, the car would handle differently. I inserted the same button actions in here but I halved the speed of the car.

I am now debating what to do next with the game. Do I start the proper graphics and menu, or do I continue with some more functionality (checkpoints etc)? Stay tuned!

Stills from a collection of particle and line studies on "self" and "presence". All simulations are real-time in Flash using video data (BitmapData). 3D work done in C4D and animated using skeletal data captured using Kinect camera. I discovered the magic of the Delauney algorithm.

Sacar el color promedio de un BitmapData

private function averageColour(source:BitmapData):uint { var red:Number = 0; var green:Number = 0; var blue:Number = 0; var count:Number = 0; var pixel:Number; for (var x:int = 0; x < source.width; x++) { for (var y:int = 0; y < source.height; y++) { pixel = source.getPixel(x, y); red += pixel >> 16 & 0xFF; green += pixel >> 8 & 0xFF; blue += pixel & 0xFF; count++ } } red /= count; green /= count; blue /= count; return red << 16 | green << 8 | blue; }

BMPContainer is an AS3 class used to draw (copyPixels) multiple BitmapData to another BitmapData and render it as a single Bitmap (or Image for Starling).

Haxe Roundup 144

The WWX 2013, the third Worldwide Haxe Conference, is taking place in Paris on May 24th til May 27th, which still has a few tickets on sale, so register soon!

Lars Doucet, Samuel Batista and the HaxeFlixel community have added BitmapData.threshold to NME for the CPP target all within a week. Almost as fast as the flash version.

For the non Haxers, how about improving your multi-platform fun by using Haxe, NME and Flambe. Seems to have worked out well for tweetfighter.nl and Nickelodeon.

If you want to get ads into your NME Android app, Lubos Lenco has recently updated his article Haxe NME with ads on Android. Looks easier than you might think.

How about native Facebook support for NME? Or native Twitter support? Hyperfiction the makers of Arkeon, have a bunch of native extensions for NME iOS and Android.

Following the tutorial FlashDevelop with Haxe NME and HaxePunk by Kyle Pulver, your'll soon be "diving into a whole new world of magic and fun".

Greg Dove has written about his first time experience with Haxe externs, LeafletJS via Haxe, loving the fact that Haxe 3 outputs "minifier-friendly" code and "that everything is type-checked as you code".

Simon Richardson has been releasing some interesting code snippets on twitter. Wildcards to curried functions is one of them.

And checkout Andrew's public alpha game CrateBreaker using NME.

If your an IntelliJ IDEA user, the Haxe plugin now has initial Haxe 3 support thanks to Fedor Korotkov.

And finally is Pazu the next version of NME or a port of NME to Emscripten? Via the HaxeFlixel forum.

ActionScript 3.0: bitmap class

This sample introduces some uses of the classes bitmap and bitmapData. The result is a simple paint app. Thanks to Joe Mondragón for this intervention.

import flash.display.Bitmap; import flash.display.BitmapData; var bmp:Bitmap = new Bitmap(); var bdata:BitmapData = new BitmapData(300, 300, false, 0xFFFFFF); bmp.bitmapData = bdata; addChild(bmp); bmp.x = 100; var picker:Bitmap = new Bitmap( new Imagen() ); var colorToPaint:uint; addChild(picker); this.addEventListener(Event.ENTER_FRAME, render); stage.addEventListener(MouseEvent.CLICK, clickMe); function render (e:Event) { var bx:int = mouseX; var by:int = mouseY; bdata.setPixel (bx - bmp.x, by - bmp.y, colorToPaint); bdata.setPixel (bx - bmp.x-1, by - bmp.y-1, colorToPaint); bdata.setPixel (bx - bmp.x, by - bmp.y-1, colorToPaint); bdata.setPixel (bx - bmp.x+1, by - bmp.y-1, colorToPaint); bdata.setPixel (bx - bmp.x-1, by - bmp.y, colorToPaint); bdata.setPixel (bx - bmp.x+1, by - bmp.y, colorToPaint); bdata.setPixel (bx - bmp.x-1, by - bmp.y+1, colorToPaint); bdata.setPixel (bx - bmp.x-1, by - bmp.y+1, colorToPaint); bdata.setPixel (bx - bmp.x, by - bmp.y+1, colorToPaint); } function clickMe(e:MouseEvent) { if (picker.hitTestPoint(mouseX, mouseY)) { colorToPaint = picker.bitmapData.getPixel(mouseX, mouseY); } }
