When I click a button in my gui, the sound plays alot of times instead of just once because th e gui is being spawned multiple times.

 

this im my gui class:

public class GuiConfirm extends GuiScreen {

public boolean doesGuiPauseGame() {
	return false;
}

@Override
public void drawScreen(int x, int y, float ticks) {
	this.buttonList.add(new GuiButton(0, this.width / 2 - 90, this.height / 2, 64, 20, I18n.format("Yes", new Object[0])));
	this.buttonList.add(new GuiButton(1, this.width / 2 + 20, this.height / 2, 64, 20, I18n.format("No", new Object[0])));
	fontRendererObj.drawString("Teleport to the PAYDAY2 Dimension?", this.width / 2 - 90, this.height / 2 - 50, 0x000000);
	GL11.glColor4f(1, 1, 1, 1);
	drawDefaultBackground();
	super.drawScreen(x, y, ticks); //I know this makes the looping.. but I tried other ways of rendering it once and nothing works..
}

@Override
protected void actionPerformed(GuiButton button) {
	if (button.id == 0){
		this.mc.displayGuiScreen((GuiScreen) null);
		this.mc.setIngameFocus();
	}
	if (button.id == 1){
		this.mc.displayGuiScreen((GuiScreen) null);
		this.mc.setIngameFocus();
	}
}
}

 

How can I make the Gui spawn only once?

You're right.. I fixed the problem right before you answered this question.. but thanks alot! I used this.buttonList.Clear();

but thanks alot!
