[1.7.10] Problems wih GUI

Recommended Posts

I have wanted to create an item that stores a player's experience, it uses a GUI inside of which I have created an int (xpStored) that should increase/decrease when you press a button, while simultaneously removing your experience/giving it back. But it doesn't seem to work. The GUI has three buttons, one that adds 1 to xpStored and removes 1 level, one that adds 1 level and decreases xpStored by 1, and the other one which closes the GUI and writes a chat message to the player, telling him how much Experience he has stored. When I have an amount of levels over 0 and try to press the first button, it executes the action of the close button.

 

My GUI code:

 

package com.nignog.mymod.gui;

import org.lwjgl.opengl.GL11;

import com.nignog.mymod.MainClass;

import net.minecraft.client.Minecraft;
import net.minecraft.client.entity.EntityClientPlayerMP;
import net.minecraft.client.gui.GuiButton;
import net.minecraft.client.gui.GuiScreen;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.util.ChatComponentText;
import net.minecraft.util.ResourceLocation;
import net.minecraft.world.World;

public class XPStorageGui extends GuiScreen {
ResourceLocation texture = new ResourceLocation(MainClass.MODID,
		"textures/gui/background.png");
private final int xSizeTexture = 248;
private final int ySizeTexture = 166;

public XPStorageGui(EntityPlayer player) {

}

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

	GL11.glColor4f(1F, 1F, 1F, 1F);
	mc.getMinecraft().getTextureManager().bindTexture(texture);

	int posX = (this.width - xSizeTexture) / 2;
	int posY = (this.height - ySizeTexture) / 2;

	drawTexturedModalRect(posX, posY, 0, 0, xSizeTexture, ySizeTexture);

	drawCenteredString(fontRendererObj, "XP Storage", posX + 125, (int) (posY + 7.5), 16777215);

	super.drawScreen(x, y, f);
}

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

@Override
public void initGui() {
	this.buttonList.clear();

	int posX = (this.width - xSizeTexture) / 2;
	int posY = (this.height - ySizeTexture) / 2;

	GuiButton XPAdd = new GuiButton(0, posX + 75, posY + 55, 100, 20, "Add XP to storage");
	GuiButton XPGet = new GuiButton(0, posX + 75, posY + 85, 100, 20, "Add XP to your bar");
	GuiButton close = new GuiButton(0, posX + 100, posY + 115, 50, 20, "Close");

	XPAdd.id = 1;
	XPGet.id = 2;
	close.id = 3;

	this.buttonList.add(close);
	this.buttonList.add(XPAdd);
	this.buttonList.add(XPGet);
}

@Override
protected void actionPerformed(GuiButton button) {
	EntityClientPlayerMP player = mc.getMinecraft().thePlayer;
	World world = mc.getMinecraft().theWorld;
	int xpStored = 0;

	switch(button.id) {
	case 1:
		if(player.experienceLevel > 0) {
			player.addExperienceLevel(-1);
			xpStored++;
		}
		else if (player.experienceLevel < 0){
			player.closeScreen();
			if(world.isRemote) {
				player.addChatMessage(new ChatComponentText("You don't have any levels!"));
			}
		}
	case 2:
		if(xpStored > 0) {
			player.addExperienceLevel(1);
			xpStored--;
		}
	case 3:
		player.closeScreen();
		if(world.isRemote) {
			player.addChatMessage(new ChatComponentText("Your XP Storage currently holds:" + " " + xpStored + " " + "Levels."));
		}
	}
}
}

 

I tried adding System.out.println(player.experienceLevel); in case 1 to test whether it can tell the player's experience level amount, and it prints it out correctly.
