Hi,
How can I make an array out of my textures? Here's the code that I tried to use, but it obviously doesn't work:
Is this the best way to load them or is there a better way?

How about this? I moved glPixelStorei and glGenTextures out of the loop. I haven't done any objective C so I can't comment on the rest. What happened when you ran your original code (how do you know it didn't work)?

- (void)loadGLTextures {
NSString *path[2];
NSImage *some_image[2];
NSBundle *bundle[2];
NSBitmapImageRep *some_bitmap[2];

int loop;
GLuint texture[2];

path[0] = [bundle[0] pathForResource:@"grass"ofType:@"tif"];

path[1] = [bundle[1] pathForResource:@"wall"ofType:@"tif"];

glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
glGenTextures(2, &texture[0]);

for(loop = 0; loop < 2; loop++) {

some_image[loop] = [[NSImage alloc]initWithContentsOfFile: path[loop] ];
bundle[loop] = [NSBundle bundleForClass:[self class]];

some_bitmap[loop] = [[NSBitmapImageRep alloc]initWithData:
[some_image[loop] TIFFRepresentation]];

glBindTexture(GL_TEXTURE_2D, texture[loop]);

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);

glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, [some_bitmap[loop] size].width,
[some_bitmap[loop] size].height, 0, GL_RGB, GL_UNSIGNED_BYTE, [some_bitmap[loop] bitmapData]);

[some_bitmap[loop] release];
}
}

Also not that you're probably going to want to keep track of the values in

GLuint texture[2];

rather than declaring them in the function. Unless you just put them there as an example...

Thanks so much I finally got it working with your code here's what I did:

Yes Ian I just put the GLuint texture[2]; there so everything was together. Also is there any way I can get it to detect if the image is transparent and change the GL_RGB to GL_RGBA?

Thank you again,
Iceman

Ok I think I got it figured out thanks to one of those great NeHe tutorials. My problem is I keep getting these errors:

This is the code I'm using to load the GL_RGBA and GL_RGB textures:

Please help me,
Iceman

There are some odd things going on with the loops. In the first loop, you set the value of bundle[0], then use all three values in the array. Then you set bundle[1] and again use all three. Thus you're sending messages to uninitialized pointers three times. Try this (untested!):

Cool! I put the alloc in the other loop because I thought the allocating was the problem, but I should have just taken the bundle out of the loop like you did. Thanks so much it works great.

Thanks again,
Iceman
