[1.12.2] [SOLVED] GUI Renders only one color of texture

[Bektor]

Hi there,

 

I'm having the problem that my GUI only renders one color of my texture.

    @Override
    public void drawButton(Minecraft mc, int mouseX, int mouseY, float partialTicks) {
        if(this.enabled && this.visible) {
            GlStateManager.color(1.f, 1.f, 1.f, 1.f);
            
            ResourceLocation BUTTON_ICON = new ResourceLocation(Constants.MOD_ID, "textures/gui/icon_test.png");
            mc.getTextureManager().bindTexture(BUTTON_ICON);
            this.drawTexturedModalRect(this.x, this.y, 0, 0, 30, 30);
            
            this.drawCenteredString(mc.fontRenderer, this.displayString, this.x + 40, this.y + (this.height - 8) / 2, 0xFFFFFF);
        }
    }

 

This piece of code only ever results into a blank texture beeing drawn instead of the (for test purposes) question mark within it beeing drawn. The texture is 32 by 32 px large.

Chaning the background of the test texture from black to transparent makes it impossible to see anything of the texture at all.

 

Thx in advance.

More accurately, its drawing your texture with no lighting. Even if your texture was white it would render black.

 

You need to disable lighting.

It is rendering a white texture just fine (as a white texture), a black texture is rendered just fine, a red texture is rendered just fine.

But now matter what colors the texture has, the question mark will not be drawn (tested with black and transparent background, red and white question marks).

My class just extends GuiButton and doesn't overwrite anything else except for this method.

Oh.

Different problem.

drawTexturedModalRect assumes textures are both square and 256 pixels wide. Your texture is 30 pixels wide and you're trying to draw all 30 pixels. What's actually being drawn is the top left corner (3.5 pixels worth).

How can I draw a texture with 30x30px?

I'm also wondering how I could scale this texture, for example when the UI element is smaller than the texture, but the full texture should be drawn within this smaller UI element.
