This is in regards to my last topic, where I was having problems with
lag, I got around to thinking that maybe it was just the way RUDL
handled opengl, and somehow caused lag, so I thought I’d go ahead and
try in normal SDL, now… so far I am running 32 polygons, and am at 200+
fps, rather then the old 20+ fps, it seems to be working perfectly now,
all for the fact SDL doesnt give me a good error message… IE:
rubyw.exe - Application Error
The exception Breakpoint
A breakpoint has been reached.
(0x80000003) occurred in the application at location 0x7c901230.
Click on OK to terminate the program
Click on CANCEL to debug the program
OK Cancel
although, I know where the problem is located, just not sure what to do
to fix it, seeing how that error is no help. It could be anything. But I
at least know its because of my code, I cant seem to load a texture
inopengl with the SDL library… my code so far is
def load_texture(texture,arr)
if (texture.nil?)
exit
end
#texture.convert!
texture.setColorKey SDL::SRCCOLORKEY, texture[0,0]
texture = texture.displayFormat
image = SDL::Surface.new(SDL::SRCCOLORKEY | SDL::SRCALPHA,
[texture.w,texture.h], 32, [0x000000FF, 0x0000FF00, 0x00FF0000,
0xFF000000])
#image.fill [0,0,0,0]
image.put(texture, [0,0])
image = image.displayFormat
GL.BindTexture(GL::TEXTURE_2D,arr[0]);
GL.TexParameter(GL::TEXTURE_2D, GL::TEXTURE_MAG_FILTER, GL::LINEAR);
GL.TexParameter(GL::TEXTURE_2D, GL::TEXTURE_MIN_FILTER, GL::LINEAR);
GL.TexImage2D(GL::TEXTURE_2D, 0, GL::RGBA,image.w, image.h, 0,
GL::RGBA, GL::UNSIGNED_BYTE, image.pixels)
end
wich is a quick transformation from the RUDL version to SDL… if anyone
knows how to load textures with SDL, tell me… I am achen to get this to
work.
