Forge Inventory Problem

[NeverMind]

Hey guys. I wanted to ask some help, because I am new to modding. How can i check if a player has an item in his inventory?

[brandon3055]

there are a couple of ways but one is to set up an event handler and use something like this.

@SubscribeEvent
public void onLivingUpdateEvent(LivingUpdateEvent event) {
if (event.entity instanceof EntityPlayer) {
	EntityPlayer player = (EntityPlayer)event.entity;
	ItemStack heldItem = player.getHeldItem();
	if (heldItem != null && heldItem.isItemEqual(new ItemStack(Items.arrow))) {
		System.out.println("True");
	}
}
}

I am afraid it didn't work. The method in my main mod class is:

public void Load(FMLLoadEvent e)

{

FMLCommonHandler.instance().bus().register(new PlayerEventHandler());

}

 

and the PlayerEventHandler class is:

 

public class PlayerEventHandler {

@SubscribeEvent

public void onLivingUpdateEvent(LivingUpdateEvent event) {

if (event.entity instanceof EntityPlayer) {

EntityPlayer player = (EntityPlayer)event.entity;

ItemStack heldItem = player.getHeldItem();

if (heldItem != null && heldItem.isItemEqual(new ItemStack(Items.arrow))) {

player.addExperience(1999);

}

}

}

}

Wrong event bus. Yes,I know. It sucks. Use MinecraftForge.EVENT_BUS.register()

Are you sure that's the problem? Because it doesn't work even if I changed to MinecraftForge.EVENT_BUS.register()

Don't get so mad. I replied to the other guy. It seems it just ignores what I coded. About your advice, I get an error when I replace LivingUpdateEvent with PlayerTickEvent

[NeverMind]

"PlayerTickEvent cannot be resolved to a type". Maybe I'm doing something very nooby.

I fixed that problem with PlayerTickEvent, but it still does nothing. Here is the code, if you can help me, you're the best:

 

public void Load(FMLLoadEvent e)

{

MinecraftForge.EVENT_BUS.register(new PlayerEventHandler());

}

 

 

public class PlayerEventHandler {

@SubscribeEvent

public void onPlayerTickEvent(PlayerTickEvent event) {

if (event.player instanceof EntityPlayer) {

EntityPlayer player = (EntityPlayer)event.player;

ItemStack heldItem = player.getHeldItem();

if (heldItem != null && heldItem.isItemEqual(new ItemStack(Items.arrow))) {

System.out.println("True");

}

}

}

}

You're right, that was a silly mistake, but even after fixing that, it just simply does nothing. When i get arrows, it doesn't do anything.

[GotoLink]

public void Load(FMLLoadEvent e)

{

MinecraftForge.EVENT_BUS.register(new PlayerEventHandler());

}

Why not FMLPreInitializationEvent ?

 

Also you could check InventoryPlayer for other methods to check item in slots and such.

Guys, I listened to your advices, it works now. Thanks a lot, that's a push for me in modding.
