Whenever i press my button in my gui, it acts, like im pressing it multiple times (random amount of times)

Here's my gui code:

package com.wizcraft.gui.gui;

import java.util.Arrays;

import org.lwjgl.opengl.GL11;

import com.wizcraft.gui.container.ContainerTableLives;
import com.wizcraft.main.MainRegistry;
import com.wizcraft.main.Reference;
import com.wizcraft.packet.KillMessage;
import com.wizcraft.packet.SlotChangeMessage;
import com.wizcraft.tile.entity.TileEntityTableLives;

import net.minecraft.client.Minecraft;
import net.minecraft.client.gui.GuiButton;
import net.minecraft.client.gui.inventory.GuiContainer;
import net.minecraft.client.resources.I18n;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.util.ResourceLocation;
import net.minecraft.util.StatCollector;

public class GuiTableLives extends GuiContainer{

private final ResourceLocation texture = new ResourceLocation(Reference.MODID, "textures/gui/guiLivTable.png");
EntityPlayer player;
TileEntityTableLives tile;

int xL,yL;

public GuiTableLives(EntityPlayer player, TileEntityTableLives tile) {
	super(new ContainerTableLives(player, tile));
	this.tile = tile;
	this.player = player;
}

@Override
protected void drawGuiContainerForegroundLayer(int x, int y) {
	fontRendererObj.drawString(I18n.format("gui.table_lives.name"), 8, 6, 4210752);
	fontRendererObj.drawString(StatCollector.translateToLocal("container.inventory"), 8, ySize - 96 + 2, 4210752);
	GuiButton button = (GuiButton) buttonList.get(0);
	String[] dsc = {I18n.format("gui.table_lives_hover1.name"), I18n.format("gui.table_lives_hover2.name")};
	if(button.func_146115_a()){
		this.drawHoveringText(Arrays.asList(dsc), x - guiLeft, y - guiTop, fontRendererObj);
	}

}

@Override
protected void drawGuiContainerBackgroundLayer(float a, int b, int c) {
	Minecraft.getMinecraft().getTextureManager().bindTexture(texture);
	this.xSize = 176;
	this.ySize = 166;
	GL11.glColor4f(1F, 1F, 1F, 1F);
	buttonList.add(new GuiButton(0, guiLeft + 72, guiTop + 57, 32, 20, "Kill"));
	drawTexturedModalRect(guiLeft, guiTop, 0, 0, xSize, ySize);
}

protected void actionPerformed(GuiButton button){
	switch(button.id){
		case 0:
			System.out.println("button");
			if(tile.slot){
				MainRegistry.network.sendToServer(new KillMessage());
				MainRegistry.network.sendToServer(new SlotChangeMessage(tile.xCoord, tile.yCoord, tile.zCoord));
			}
	}
}

}

bump

1. Too fast bump (much too fast).

 

2. You are adding infinite number of "new GuiButton" to your gui. basically - each FPS, one more button. If buttons overlay each other - all will be pressed, thus - multiple clicks.

 

3. You should be adding Buttons in initGui() (not neccessary, the point is - do it once).

 

4. Point of interest: minecraft handles buttonList.clear() for you (just before initGui() is called), but if you were to call initGui() on your own, or add more buttons while gui is alredy opened - remember to clear the list 1st (or remove unused). I am refering to guis that have e.g multiple pages with different buttons on each.

Sorry for the bump 

 

But Thanks, now it is working perfectly
