I have a KeyInputHandler where i check for two inputs, when the player presser O and P

 

package com.crax.portalgunmod;

import net.minecraft.client.Minecraft;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;

import com.crax.portalgunmod.resources.KeyBindings;

import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.InputEvent;

public class KeyInputHandler {
//if(player.getHeldItem().equals(new ItemStack(Items.diamond)))

@SubscribeEvent
public void onKeyInput(InputEvent.KeyInputEvent event){

	//if(portalGunMod.player.getHeldItem().equals(new ItemStack(portalGunMod.portalGunItem))){
		if(KeyBindings.leftMouse.isPressed()){
			System.out.println("Shooting left portal!");
		}
		if(KeyBindings.rightMouse.isPressed()){
			System.out.println("Shooting right portal!");
		//}
	}
}
}

 

And this is my main class: 

package com.crax.portalgunmod;

import java.rmi.registry.Registry;

import com.crax.portalgunmod.resources.KeyBindings;
import com.crax.portalgunmod.resources.Resources;

import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.util.ChatComponentText;
import net.minecraft.util.ChatComponentTranslation;
import net.minecraft.client.Minecraft;
import net.minecraft.entity.player.EntityPlayer;
import cpw.mods.fml.common.FMLCommonHandler;
import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.EventHandler;
import cpw.mods.fml.common.Mod.Instance;
import cpw.mods.fml.common.SidedProxy;
import cpw.mods.fml.common.event.FMLInitializationEvent;
import cpw.mods.fml.common.event.FMLPreInitializationEvent;
import cpw.mods.fml.common.event.FMLPostInitializationEvent;
import cpw.mods.fml.common.registry.GameRegistry;
@Mod(modid=Resources.modid, name="PortalMod", version="0.0.1")

public class portalGunMod {
public static Item portalGunItem;
public static EntityPlayer player = Minecraft.getMinecraft().thePlayer;
//ItemStack actualHeldObject = portalGunMod.player.inventory.getCurrentItem();
@Instance(value=Resources.modid)
public static portalGunMod instance;

@SidedProxy(clientSide="com.crax.portalgunmod.client.ClientProxy", serverSide="com.crax.portalgunmod.server.CommonProxy")
public static CommonProxy proxy;

@EventHandler
public void preInit(FMLPreInitializationEvent event){
	portalGunItem = new PortalGunItem();
	GameRegistry.registerItem(portalGunItem, "portalGunItem");
}

@EventHandler
public void load(FMLInitializationEvent event){
	KeyBindings.init();
	}

@EventHandler
public void postInit(FMLPostInitializationEvent event){

}

}

 

I need to do the actions binded in the keybindings only when the player helds a portalgun item

 

I tried with getting these lines of code: 

//in portalGunMod, after the player declaration
ItemStack actualHeldObject = portalGunMod.player.getItemInUse();



//in KeyInputHandler class
if(portalGunMod.player.getHeldItem().equals(new ItemStack(portalGunMod.portalGunItem))){
		if(KeyBindings.leftMouse.isPressed()){
			//System.out.println("Shooting left portal!"+ actualHeldObject.getUnlocalizedName());
		}
		if(KeyBindings.rightMouse.isPressed()){
			System.out.println("Shooting right portal!");
		}

 

I need help, i almost lost my voice for all the curses when the game crashes

player#getCurrentEquippedItem()

 

Also your KeyBindings are purely client-side, just as a note, so you have to send packets when trying to change something on the server.

This also means that your KeyBindings.init(); method should be called in your client proxy.

mah twitter

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.

So, this is how i corrected the KeyInputClass

package com.crax.portalgunmod;

import net.minecraft.client.Minecraft;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;

import com.crax.portalgunmod.resources.KeyBindings;

import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.InputEvent;

public class KeyInputHandler {
//if(player.getHeldItem().equals(new ItemStack(Items.diamond)))

@SubscribeEvent
public void onKeyInput(InputEvent.KeyInputEvent event){

	//if(portalGunMod.player.getHeldItem().equals(new ItemStack(portalGunMod.portalGunItem))){
		if(KeyBindings.leftMouse.isPressed()){
			System.out.println("Shooting left portal!" + portalGunMod.player.getCurrentEquippedItem().getDisplayName());
		}
		if(KeyBindings.rightMouse.isPressed()){
			System.out.println("Shooting right portal!");
		//}
	}
}
}

 

It keeps crashing.

You need to check if the item held is null, If the hands are empty -> held item is null

Don't ask for support per PM! They'll get ignored! | If a post helped you, click the "Thank You" button at the top right corner of said post! |

mah twitter

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.

AAARGH ç.ç

 

I tried this : 


	//if(portalGunMod.player.getHeldItem().equals(new ItemStack(portalGunMod.portalGunItem))){
	if(portalGunMod.player.getCurrentEquippedItem()!= null )
		if(KeyBindings.leftMouse.isPressed()){
			System.out.println("Shooting left portal!" );
		}
		if(KeyBindings.rightMouse.isPressed()){
			System.out.println("Shooting right portal!");
		//}
	}

and this: 

public void onKeyInput(InputEvent.KeyInputEvent event){

	//if(portalGunMod.player.getHeldItem().equals(new ItemStack(portalGunMod.portalGunItem))){
	if(!portalGunMod.player.getCurrentEquippedItem().equals(null))
		if(KeyBindings.leftMouse.isPressed()){
			System.out.println("Shooting left portal!" );
		}
		if(KeyBindings.rightMouse.isPressed()){
			System.out.println("Shooting right portal!");
		//}
	}
}

 

But nothing! I always crash!

Show your KeyBindings class.

 

Edit: portalGunMod.player is null you need to ether get the player when the key input event is fired or add the following method to your portalGunMod class and use it to get the player.

 

public static EntityClientPlayerMP getClientPlayer(){
return Minecraft.getMinecraft().thePlayer;
}

 

Regarding your current setup im not sure exactly how it works but i think the player field is being initialized during the mod construction faze during which time the player dose not exist. The player dosnt exist until you log into the world.

Also if you were to store the player in a field such as that i believe it would become null the next time the player dies (but im not sure about that)

 

Edit 2: A good way to track down a problem like that is to add some println's to find out what is null and where things go wrong . Also "java.lang.NullPointerException: Unexpected error" Is telling you that a value is null.

"at com.crax.portalgunmod.KeyInputHandler.onKeyInput(KeyInputHandler.java:20)" Is telling you the class and line on which the error occurred. Usually you can click on it and it will take you to the error then you just have to figure out what you did wrong.
