Hello, I have a problem with texture loading. I load several textures and when I display them on rectangles, the last one is mapped on every rectangle. I am doing this with Java and gl4java but I already have had this bug in C. // Loading texture Textures = new int[3]; gl.glGenTextures(3, Textures); LoadTGATexture("newgame.tga", Textures[0]); LoadTGATexture("loadgame.tga", Textures[1]); LoadTGATexture("options.tga", Textures[2]); // displaying texture 1 gl.glBegin(GL_QUADS); gl.glBindTexture(GL_TEXTURE_2D, Textures[0]); gl.glTexCoord2f(0.0f, 0.0f); gl.glVertex2i(0, 0); gl.glTexCoord2f(0.0f, 1.0f); gl.glVertex2i(0, 40); gl.glTexCoord2f(1.0f, 1.0f); gl.glVertex2i(100, 40); gl.glTexCoord2f(1.0f, 0.0f); gl.glVertex2i(100, 0); gl.glEnd(); The texture displayed is the last one : "options.tga" I tried with PNG image as well and it does not work either. Waiting for your help, thanks Ereinion

This is what I do with the line :
gl.glBindTexture(GL_TEXTURE_2D, Textures[0]);

Is that wrong ?

Ereinion

thanks for the advice,
I tried but it didn''t change anything

if you have any ideas, they''re welcome !

The loading function has worked very well until now. I really dont understand what is going on ...

i think your loading function works right... else there must be a very strange error in it. ( because if a texture is loaded and you always just overgive a pointer to GLubyte i cant imagin how to overwrite other memory... such an error would be to stupid )

i would even think that you perhaps are doing a little mistake while binding the texture... perhaps you could post the whole thing in here.

OK Here is my whole code.
The loading part is in "init", the displaying part is in "display" and the loading function is called LoadTGATexture and is at the end of the code.
If you have any questions to understand the code (though I''d prefer answers to my problem ) please ask.

Please someone answers, I really need help with this one.
Any idea is welcome, even the most "stupid" ones.
