Hello nds comrades!

I have a problem regarding a function I made:

void CreateTexturePCX(const u8 *imagedata, int &texture)
{
	sImage pcx;
	
	loadPCX((u8*)imagedata, &pcx);
	
	image8to16trans(&pcx, 255);

	glGenTextures(1, &texture);
	glBindTexture(0, texture);
	
	glTexImage2D(0, 0, GL_RGBA, TEXTURE_SIZE_256 , TEXTURE_SIZE_256, 0, TEXGEN_TEXCOORD, pcx.image.data8);

	imageDestroy(&pcx);
}

This function is meant to create a texture for useage, but it only works the first call. :/
I can't figure out why right now.. maybe anyone can share some of their knowledge?

Here's the calls:

Code: Select all

CreateTexturePCX(lagualogo_pcx, lagualogo_texture);//<--Works
CreateTexturePCX(tilemap_level01_pcx, tilemap);//<--Not

I thank you for sharing your wisdom!

EDIT:
Oh, if I switch place between the calls the first call works and the other doesn't so there's nothing wrong with the input data.

What's the size of your textures (width x height) and how may VBANK did you set as TEXTURE memory ?

Each of the first 4 VBANK can hold 128k (131,072 bytes) and each texture in RGB/RGBA will take up to (w x h x 2) bytes.

You might need more texture VRAM banks or smaller textures.

That explains it, the size of the textures is 256x256.

It works now!

Thank you very much wierdfox

I'll be sure to mention you in the credits if I even finish this game.
