I really want to implement drawing order in my node based graphics engine in vsge.
Node based meaning, that I actually have a nodetree, each node containing a pointer to the parent and a children list. This means that each node handles drawing of the children, so the graphics engine only calls the base drawing function (which draws its children, which draw their children).
Now back to drawing order. If I don't use the z-Buffer which isn't supported by allegro itself, therefore requires a lot of weird work wit openGL and I wouldn't be able to use the allegro blitting functions with it.
My idea was to create a list out of the nodetree and sort it by a z-coordinate. I would have to do that every frame though, which can't be good for performance.
Since Allegro 5 has been released a long time ago, I thought I'd give it a try. I was pretty impressed by it, so I started rewriting my vsge2D game engine (which really just had only a basic structure though) using Allegro 5.
This turned out to be a lot of work, but eventually I got the graphics back, and am almost done with the input (joypad).
I once had the idea to have a game programming library abstraction layer. Don't know what happened to that :P
I have this problem in two of my projects where applications just crash at random moments. And if I say random, I mean random. No connection to what is going on in the rest of the application.
I am making this demo-game for vsge2D: "Blue Moon", a project I have long ago abandoned because started with too less programming skills. Now it's supposed to help me add new features to vsge2D.
In my last post I wrote about entities shooting bullets. There was this point where I got that working, but the game tended to crash after a random number of bullets. (It was not a certain amount of time until the crash, I checked that as well.)
That's a quite scary moment for me as a programmer who didn't have to deal with such a strange problem for a long time now, because my usual debugging methods don't apply for this sort of bug. But I didn't give up, and found the problem:
First thing you have to know is that my graphics based on nodes is drawn recursively. Nodes have children which are drawn when the graphics engine draws their parent node.
Only the upper-most nodes are added to the graphics engine itself. (I wonder if it would be more efficient to add everything to one node in the engine??)
That means the parent pointer is NULL when the node is in the engine. In the entity copy-constructor the node is copied and entity determines whether it has a parent and so whether to add it to the engine or not. (I am getting the feeling my idea with the one node makes a lot more sens :P )
The problem in the end was that in the copy-constructor of the node, I had not set the pointer to the parent to NULL, so it got a random value from the RAM. Sometimes this went well, and well.... sometimes it didn't and the application crashed.
(Okay, I think I'll do that one node in engine thing... or does somebody have a better idea, maybe?)
