I have a bug when I open my GUI (or try to). IT DOESN'T WORK AND CRASHES THE GAME!

Here is my relevant code=

NetworkProxy:

package com.sear.tutorial.proxy;

import com.sear.tutorial.Tutorial;
import com.sear.tutorial.gui.GuiHandler;

import cpw.mods.fml.common.network.NetworkRegistry;

public class ServerProxy {
public void registerRenderThings(){


}
public void registerNetworkStuff(){
	NetworkRegistry.INSTANCE.registerGuiHandler(Tutorial.modInstance, new GuiHandler());

}
}

GuiHandler:

package com.sear.tutorial.gui;

import scala.Console;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.world.World;

import com.sear.tutorial.Tutorial;
import com.sear.tutorial.gui.containerMagicGui;

import cpw.mods.fml.common.network.IGuiHandler;
import cpw.mods.fml.common.network.NetworkRegistry;

public class GuiHandler implements IGuiHandler{
public GuiHandler(){
	NetworkRegistry.INSTANCE.registerGuiHandler(Tutorial.modInstance, this);
	Console.out().println("RUBIES: GuiHandler registered.");

}
@Override
public Object getServerGuiElement(int ID, EntityPlayer player, World world,
		int x, int y, int z) {

	if(ID == 0){
		return new containerMagicGui(player);			
	}
	else{

	return null;
	}
}

@Override
public Object getClientGuiElement(int ID, EntityPlayer player, World world,
		int x, int y, int z) {

	if(ID == 0){
		return new magicGui(player);
	}
	else{
		return null;

	}

}

}

MagicGui:

package com.sear.tutorial.gui;

import org.lwjgl.opengl.GL11;

import scala.Console;

import com.sear.tutorial.Tutorial;
import com.sear.tutorial.magic.spells;

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

public class magicGui extends GuiScreen{
ResourceLocation texture = new ResourceLocation(Tutorial.MODID, "textures/gui/magicGui.png");
public final int xSizeOfTexture= 200;
public final int ySizeOfTexture= 500;
public magicGui(EntityPlayer player){

}
@Override
public void drawScreen(int x, int y, float f){
	drawDefaultBackground();
	GL11.glColor4f(1F, 1F, 1F, 1F);
	Minecraft.getMinecraft().getTextureManager().getTexture(texture);
	int posX = (this.width - xSizeOfTexture) / 2;
	int posY = (this.height - ySizeOfTexture) / 2;
	drawTexturedModalRect(posX, posY, 0, 0, xSizeOfTexture, ySizeOfTexture);
	super.drawScreen(x, y, f);
	Console.out().println("RUBIES: MagicGUI screen drawn.");
}
@Override
public boolean doesGuiPauseGame(){
	return false;

}
public void initGui(){

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

	this.buttonList.add(new GuiButton(1, posX, posY, 200, 20, "Fireball"));
	this.buttonList.add(new GuiButton(2, posX, posY + 20, 200, 20, "Ice Blast"));
	this.buttonList.add(new GuiButton(3, posX, posY + 20, 200, 20, "Weak Heal"));
	this.buttonList.add(new GuiButton(0, posX, posY + 20, 200, 20, "No Spell..."));
}
public void actionPerformed(GuiButton button){
	switch(button.id){
		case 0: spells.setActiveSpell(0);
		case 1: spells.setActiveSpell(1);
		case 2: spells.setActiveSpell(2);
		case 3: spells.setActiveSpell(3);
		default: Minecraft.getMinecraft().thePlayer.sendChatMessage("I am really good at breaking things!");

	}
	Console.out().println("RUBIES: MagicGUI Switch completed.");
}
}

ContainerMagicGui:

package com.sear.tutorial.gui;

import scala.Console;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.inventory.Container;

public class containerMagicGui extends Container{
public containerMagicGui(EntityPlayer player){
	Console.out().println("RUBIES: Dunno what this is... some server-side GUI mumbo-jumbo? But it's loaded, and that's the point.");

}
@Override
public boolean canInteractWith(EntityPlayer var1) {
	return true;
}

}

And the class that calls all this:

package com.sear.tutorial.magic;

import scala.Console;
import net.minecraft.client.renderer.texture.IIconRegister;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;

import com.sear.tutorial.Tutorial;

import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;

public class ItemWarlockSpellbook extends Item {
public boolean hasEffect(ItemStack par1ItemStack){
	return true;

}
public ItemWarlockSpellbook(){
	super();
	setUnlocalizedName("ItemWarlockSpellbook");
	setTextureName(Tutorial.MODID + ":" + getUnlocalizedName().substring(5));
	setCreativeTab(Tutorial.tabMagic);
	setMaxStackSize(1);
}
@Override
public ItemStack onItemRightClick(ItemStack itemstack, World world, EntityPlayer player)
    {
	Console.out().println("RUBIES: GUI is attempting to open...");
	player.openGui(Tutorial.modInstance, 0, world, (int)player.posX, (int)player.posY, (int)player.posZ);
	Console.out().println("RUBIES: GUI should have opened, check console.");
        return itemstack;
    }
@Override
@SideOnly(Side.CLIENT)
public void registerIcons(IIconRegister icon) {
	this.itemIcon = icon.registerIcon(Tutorial.MODID + ":" + getUnlocalizedName().substring(5));

}
}

It has me stumped... Can anyone figure out why this is happening?

bump bump BUMP, this is very urgent!

 

 

[move]SOMEBODY HELP ME PLEASE[/move]

BUUUUMP

Need more info. This isn't enough information to know EXACTLY what's wrong, but I would advise opening the GUI on the client.

I have noticed that you have registered your GuiHandler twice. Once in your registerNetworkStuff() method, and then inside the constructor of your GuiHandler. Try removing the one inside your GuiHandler's constructor and see if that fixes it. If it doesn't, post the crash report.

As the others said, no stacktrace=no help

It fixed it... partially. The GUI will open and close now, but buttons don't do ANYTHING.

So..

How do I set the texture of a button?, and

How do I see if it is working?

Bump. Sorry I'm bumping so much but I have to fix this by 2:00 Pacific time. That's 5 hours till deadline.

Use the actionPerformed method. You get a GuiButton parameter which you can use to get the id, which you canuse to identify the button, and do stuff based on the button that was clicked.

I did. I actually solved the button problem by doing *gasp* nothing.

I just tried gradlew building it again and it worked fine. Weird.
