My speedhack entry. I'm too tired to write about it now. EDIT: Fix for ATI (and hopefully Intel) users now included. EDIT2: Linux Fix #1: Edit gamestate.cpp, function set_map() and change: this->switch_to_map = ~0; To: this->switch_to_map = ~0u;

The effects were too much for my laptop's video card, it seems. When I grabbed a fruit it would lockup until the effect stopped. I'll try it on my desktop tomorrow. Looks slick, though, from what I could see.

I make liberal use of glCopyTexImage(). I suppose it's not all that fast on non-Nvidia cards. One thing you can try is to force NV_texture_rectangle to be used by replacing render.cpp, lines 538 from: GLenum target = allegro_gl_extensions_GL.NV_texture_rectangle | allegro_gl_extensions_GL.ARB_texture_rectangle ? GL_TEXTURE_RECTANGLE_NV : GL_TEXTURE_2D; to: GLenum target = GL_TEXTURE_RECTANGLE_NV; Same for lines 415 and 481. I think ATI exposes a similar extension (EXT_texture_rectangle) that is undocumented. EDIT: I've done some fixes in the code. Looks like I've been liberally using non-power-of-two textures, which aren't well supported on non-NV cards. The latest executable+source should have some quick fixes that ought to help. -- |

The opening screen, the music and the menu work, but when I want to play, the game crashes: Shutting down Allegro due to signal #11 Segmentation fault
Judging by the screenshots we had some pretty similar ideas, although my implementation was a lot less sophisticated... -- |

Can you compile with -g3 and without -O3? That should also give you line numbers. (set_map() has way too many lines of code). -- |

Yes. And the game looks amazing! EDIT: But now it exits randomly after 20 or so seconds. EDIT: Or maybe a few seconds after picking up the coconut.

Odd. Somehow, Allegro thinks v > 1, but here's the call to hsv_to_rgb in render.cpp: hsv_to_rgb(rotate, 1, 1, &r, &g, &b); Why is 1 getting rounded to anything but 1.0? Maybe try replacing it by 0.9999 and see if that helps? -- |

Nope, but adding this before that function call does help: while (rotate < 0) { rotate += 360.0; } while (rotate > 360.0) { rotate -= 360.0; }
