Some Thoughts on a Node Based Particle System
My vsge game engine uses a node based graphics engine. This makes parenting really easy for example. Entities of the game engine own a graphics node and update it’s transform, so they can be displayed to the screen easily.
Calling the nodes drawing procedures is handled by the graphics …
al_uninstall_sytem()
I spent 2 hours debugging last night and another 2 hours today to find the reason for random crashes at application exit.
When using Allegro 5 in a shared library, it is very important to use al_uninstall_system() manually (I guess allegro can’t call this in atexit() in those cases …

I am making this demo-game for vsge2D: “Blue Moon”, a project I have …

So what’s the …
Fixed my MinGW + Allegro Problems
In the end it wasn’t even the sjlj/dw2 problem after all. I thing I had a buggy snapshot of MinGW or so, or failed when using mingw-get-inst ;P
Whatever it was, my compiler is working and I’m happy.
