Changing Libraries from Allegro

[seanmusgrave 122]

Hello, So I want to start developing games with more 3d functionality. I liked using Allegro quite abit, and probably will continue using it for 2D games. I'm pretty sure I want to use OGL, so the obvious choice is using AllegrOGL. However, I'm concerned because I've heard it being rather difficult to set up correctly, and I've had problems myself setting up a basic screen. So I've got the following questions: * Would I be better off using SDL or something else for OGL, even though I'm already comfortable with Allegro? * Can you point to any tutorials on using AllegroGL? I found one, http://pixwiki.bafsoft.com/mags/6/articles/agl-a/agl01.html, but its examples didn't work when I tried running them (Wheras I've been able to run other examples fine) * Can I use AllegroGL to make a faster 2d program using a large number of sprites and transparency effects than allegro? Thanks!

I would first try to use the documentation on the official site, and then look for tutorials on anything that's missing.

Using OpenGL for 2D rendering can definetly give a performance boost in 2D games, because it can use 3D hardware acceleration for many effects that are done in software using Allegro. Just make sure you don't use the pixel manipulation functions to draw your images, because they are slow. Use textured quads instead.
