two things...

[method5]

first... my when adding my textures to my tiles.. they are upside down and backwards???? i brought a screenshot into photoshop and had to turn 180 degrees and flip horizontaly to get it to look right...

to display my tiles i am using..


glBindTexture(GL_TEXTURE_2D, tiles[tile]);
glBegin(GL_QUADS);
glTexCoord2f(0.0f,0.0f);
glVertex2f(drawingx, drawingy);
glTexCoord2f(1.0f,0.0f);
glVertex2f(drawingx + 32, drawingy);
glTexCoord2f(1.0f,1.0f);
glVertex2f(drawingx + 32, drawingy + 32);
glTexCoord2f(0.0f,1.0f);
glVertex2f(drawingx,drawingy + 32);
glEnd();


any ideas?


also.. the textures I am loading.. (bitmaps) are being antialised... meaning blured a little. how do I stop that? i want sharp pixels..

nevermind about 2 just please help with the first thing.

Hi. Bitmaps by default are stored "upside down." You can do what you did and save it upside down in Photoshop, or flip it using glPixelZoom()

where would i put this glPixelZoom(1.0,-1.0); ?

Hi. After you have loaded the .bmp and before you make the call to glTexImage2d(), or glDrawPixels() etc... So:
glPixelZoom(-1.0f, 1.0f); // flip it horizontally baby!
glPixelZoom( 1.0f,-1.0f); // flip it right side up baby!

ive tried it a few places.. and it doenst seem to be working.. do you have aim (kdghsu) or icq (21159213)? thank you

[method5]

is there something you have to do it enable it first before you can use those?

[Old GLman]

Hi. I know for a fact that glPixelZoom() can be used to flip .bmps, I have done it myself. It is probably working, but not positioned right. In other words it may just not be in view. Set the raster position with glRasterPos2f().
Let me know if you have any more problems.
