Update text on gui

[GodOfYeti]

I want to update the text on my gui when the "+" button is pressed

 

heres the gui code

package com.mcpixelplex.Gui;

import org.lwjgl.opengl.GL11;

import com.mcpixelplex.lib.RefStrings;

import net.minecraft.client.Minecraft;
import net.minecraft.client.gui.GuiButton;
import net.minecraft.client.gui.GuiScreen;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.util.ResourceLocation;


public class TestGui extends GuiScreen {

Minecraft mc = Minecraft.getMinecraft();

GuiButton testButton;

public String[] levelDisplay = new String[]{"1","2","3","4","5","6","7","8","9","10"};
public int level = 0;

public final int xSizeOfTexture = 256;
public final int ySizeOfTexture = 156;

public TestGui(EntityPlayer player){

}

@Override
public void drawScreen(int x, int y, float f){

	int posX = (this.width - xSizeOfTexture) / 2;
	int posY = (this.height - ySizeOfTexture) / 2;

	GL11.glColor4f(1F, 1F, 1F, 1F);
	mc.renderEngine.bindTexture(new ResourceLocation(RefStrings.MODID, "/textures/gui/background.png"));

	drawDefaultBackground();
	drawTexturedModalRect(posX, posY, 0, 0, xSizeOfTexture, ySizeOfTexture);

	fontRendererObj.drawString("XP Block", posX + 20, posY + 5, 0x000000);		
	fontRendererObj.drawString(levelDisplay[level], xSizeOfTexture / 2, ySizeOfTexture / 2, 0x000000);	

	super.drawScreen(x, y, f);

}

public void initGui(){

	int xSize = 100;
	int ySize = 20;

	int posX = (xSizeOfTexture) / 2;
	int posY = (ySizeOfTexture) / 2;

	int bottomButton = (ySizeOfTexture - ySize - 2);

	buttonList.clear();
	buttonList.add(new GuiButton(0, posX + 40, bottomButton + 40, 100, 20, "no use"));
	buttonList.add(new GuiButton(1, posX + 40, posY + 40, 20, 20, "+"));

	super.initGui();
}

public void actionPreformed(GuiButton button){
	switch(button.id){
	case 0:
		break;
	case 1:
		if(level == 10){

		}else{
			level++;
		}
	}
}

@Override
public boolean doesGuiPauseGame(){
	return false;
}

}

Spelling mistake on actionPerformed method your wrote "actionPreformed", should be Performed

 

 

P.S. This does not relate with your problem but, the super.initGui call is useless in the initGuid() method as it's super implementation has no body
