Hello!

 

Following tidbits of tutorials, I've managed to come up with a very small GUI class. I can open it, but can't render anything on it. The only thing that makes any difference is this.drawDefaultBackground().

I am showing the GUI with "Minecraft.getMinecraft().displayGUIScreen(new MyGuiClass());".

The GUI class:

 

Minecraft mc = Minecraft.getMinecraft();

public static final int GUI_ID = 20;

@Override
    public void drawScreen(int mouseX, int mouseY, float partialTicks){
	this.drawDefaultBackground();
	this.buttonList.add(new GuiButton(1, 50, 50, 10, 10, "Hi"));
}
@Override
public void initGui(){
	super.initGui();
	this.buttonList.add(new GuiButton(1, 50, 50, 10, 10, "Hi"));
}

 

The button does not load, and I do not get any errors. I put it on both initGui and drawScreen for testing purposes, probably not the best idea.

Indeed that is not a good idea. Only add buttons in initGui.

You must call super.drawScreen as that is where the button drawing happens.

Thank you, I just realized this before I saw your post.
