Hello everyone. I’m having a bit of a problem, and I can’t seem to fix it myself. Trying to make an inventory script for my game I get the following error on line 58:

Operator “==” cannot be used with a left hand side of type ‘InventoryItem’ and a right hand side of type ‘SystemObject’

This is my script:

@script AddComponentMenu ("Inventory/Inventory")

enum InventoryItem{
	DEBUG_ITEM,
	TRASH_SMALL,
	TRASH_BIG,
	CHOCOLATE_BAR,
	ENERGY_DRINK,
	BATTERY_SMALL,
	BATTERY_LARGE,
	REPAIR_KIT,
	NUTS_AND_BOLTS,
	AMMO_BULLETS,
	COUNT_NUM_ITEMS
}

var inventory: int[];

// LINKS TO BUDDY'S STATUS MANAGER
var buddyPlayerStatus: BuddyStatus;
buddyPlayerStatus = GetComponent(BuddyStatus);

// LINKS TO PAL'S STATUS MANAGER
var palPlayerStatus: PalStatus;
palPlayerStatus = GetComponent(PalStatus);

private var chocolateBarAmount = 2.0;
private var energyDrinkAmount = 5.0;
private var batterySmallAmount = 20.0;
private var batteryLargeAmount = 100.0;
private var nutsAndBoltsAmount = 2.0;
private var repairKitAmount = 5.0;

function Start(){

	inventory = new int[InventoryItem.COUNT_NUM_ITEMS];
	
	for (var item in inventory){
		inventory[item] = 0;
	}
	
	// STARTING ITEMS
	inventory[InventoryItem.CHOCOLATE_BAR] = 2;
	inventory[InventoryItem.BATTERY_SMALL] = 2;
	inventory[InventoryItem.NUTS_AND_BOLTS] = 2;
}

// PICK UP ITEMS
function GetItem(item: InventoryItem, amount: int){
	inventory[item] += amount;
}

// USE ITEMS
function UseItem(item: InventoryItem, amount: int){
	if(inventory[item] <= 0) return;
	inventory[item] -= amount;
	
	switch(item){
		case InventoryItem.CHOCOLATE_BAR:
			buddyPlayerStatus.AddHealth(chocolateBarAmount);
			break;
		case InventoryItem.ENERGY_DRINK:	
			buddyPlayerStatus.AddHealth(energyDrinkAmount);
			break;
		case InventoryItem.BATTERY_SMALL:
			palPlayerStatus.AddBattery(batterySmallAmount);
			break;
		case InventoryItem.BATTER_LARGE:
			palPlayerStatus.AddBattery(batteryLargeAmount);
			break;
		case InventoryItem.NUTS_AND_BOLTS:
			palPlayerStatus.AddHealth(nutsAndBoltsAmount);
			break;
		case InventoryItem.REPAIR_KIT:
			palPlayerStatus.AddHealth(repairKitAmount);
			break;
	}
}

case InventoryItem.BATTER_LARGE:
palPlayerStatus.AddBattery(batteryLargeAmount);
break;

you’ve got a typo: BATTER_LARGE should be BATTERY_LARGE

since batter_large isn’t part of your enum it’s defaulting the type to “Object”, the case statement is then doing an [InventoryType] == [Object] which is causing the error.
