[Paused] [1.8.9] How to detect if item is in inventory, then remove it?

[FireController1847]

Title really says all, I'm developing an addon for MrCray's Device Mod, and I want it to give the player 'money' when they press a button. By doing that, I need to figure out how to detected if an item is in the players inventory.

Any specific slot? Players hand? And input would be using a KeyHandler and possibly the KeyInputEvent

[FireController1847]

I've got the input figured out, Mr. Crayfish made an API, all I need to know is if the item is in the players inventory, and then if it is to remove it.

Do you have access to a EntityPlayer variable? If so there is a thing called inventory in there.

[FireController1847]

I have access to the EntityPlayerSP variable. What for inventory would I use to search for an item?

First EntityPlayerSP is not a variable you can use, you will need to send packets. This is a link to Diesieben07's tutorial on Packets.

is there a reason why I'd have to do this? I am very easily able to get the itemstack on the inventory using this...

 

Minecraft.getMinecraft().thePlayer.inventory.mainInventory

 

That is an item stack list

 

EDIT:

When I do print System.out.println(player.inventory.mainInventory[5]); to console, it outputs ...

 

1xtile.lightgem@0

 

When I print out ItemStack testItem = new ItemStack(Blocks.glowstone);, it outputs ...

 

1xtile.lightgem@0

 

Yet the if-statment I have given it doesn't work?

 

	final EntityPlayerSP player = Minecraft.getMinecraft().thePlayer;

	ItemStack testItem = new ItemStack(Blocks.glowstone);

	System.out.println(player.inventory.mainInventory[5]);
	System.out.println(testItem);

	if (player.inventory.mainInventory[5] == testItem) {
		System.out.println("HE HAS IT");
	} else {
		System.out.println("It ain't glowstone");
	}

 

Full Output:

[19:25:30] [Client thread/INFO] [sTDOUT]: [com.fire.cdmbloxread.apps.ApplicationBloxRead:init:36]: 1xtile.lightgem@0
[19:25:30] [Client thread/INFO] [sTDOUT]: [com.fire.cdmbloxread.apps.ApplicationBloxRead:init:37]: 1xtile.lightgem@0
[19:25:30] [Client thread/INFO] [sTDOUT]: [com.fire.cdmbloxread.apps.ApplicationBloxRead:init:42]: It ain't glowstone

That is client side you can grab what there is client side and modify it, but since all data is saved and should be modified on the server. It will just be overriden by the server. Thus a packet is required.

Ugh.. Okay. I'll wait and see if Mr. Crayfish implements a way to get the EntityPlayer from the player who is using the PC.
