It appears more than once, this is with the texture size being 512x512 (Same thing occurs when cropped to the proper size of 372x166). Anyone that can help?

 

@Override protected void drawGuiContainerBackgroundLayer(float partialTicks, int mouseX, int mouseY) {
	GlStateManager.color(1, 1, 1, 1);
	this.mc.getTextureManager().bindTexture(backgroundTexture);
	drawTexturedModalRect(this.guiLeft, this.guiTop, 0, 0, xSize, ySize); //xSize being 372, ySize being 166
}

 

I'm pretty sure the texture has to be 256x256

drawTexturedModalRect uses a 256 x 256 texture.

 

If you want to load a different size you'll need to make your own draw function. scratch that.

0.00390625F is 1 / 256

 

Edit:

Ernio is correct, drawModalRectWithCustomSizedTexture is what you want.

 

 

For my mods in-game wiki I needed scaling, flipping, and custom sizes; so I coded a function that did everything and completely forgot Minecraft had more then drawTexturedModalRect

(not sure when drawScaledCustomSizeModalRect appeared but I'm sure it wasn't there before, I could have used it for about 2/3rds of my images)

If you want to load a different size you'll need to make your own draw function.

0.00390625F is 1 / 256

 

I'd like to note that there is alredy method that has size args (...withCustomSize() or something).

 

Since you are drawing container, I'd also like to note: (might come in handy)

I was about to post about how it still doesn't worked and then realised you put lots of emphasis on the fact xSize and ySize has to be in the constructor. I noticed that mine were just declared outside of it, changed it, and it worked. Thank you guys so much for helping to fix this.
