I'm trying to make an item which decays into another item over time. I've managed to get the decaying to work properly, which was a post i put on here a while ago and got no responses to, but now when the stack changes the Item it is replaced with is not of the same type as it should be (i.e. i tried changing it to stone for test purposes but the item it is replaced with will not stack with stone. Anyone know how to fix this?

 

Here's the relevant parts of the code:

	@Override
public void onCreated(ItemStack stack,World world,EntityPlayer player)
{	
	if(stack.itemID == ModResorces.decay.shiftedIndex){
		setWorldTimer(stack, world);
	}
}

@Override
 public void onUpdate(ItemStack stack, World world, Entity entity, int par4, boolean par5)
{
	if(stack.stackTagCompound == null && stack.itemID == ModResorces.decay.shiftedIndex){
		setWorldTimer(stack, world);
		return;
	}else if(stack.itemID != ModResorces.decay.shiftedIndex){
		return;
	}
	if(world.getTotalWorldTime() >= stack.stackTagCompound.getLong("EndTime")){
		stack.itemID = 1;
	}else{
		stack.setItemDamage(201 - (int)(stack.stackTagCompound.getLong("EndTime") - world.getTotalWorldTime()));
	}
}


public void setWorldTimer(ItemStack stack, World world)
{
	if(stack.itemID == ModResorces.decay.shiftedIndex && stack.stackTagCompound == null)
	{
		stack.setTagCompound(new NBTTagCompound());
	}
	stack.stackTagCompound.setLong("EndTime", world.getTotalWorldTime() + 200);
}

What about:

stack = new ItemStack(Block.stone);

I attempted that but it wouldn't replace the stack at all 

Probably the player don't get the changes,add this after changing itemstack.

((EntityPlayer)entity).inventoryContainer.detectAndSendChanges();

sounds reasonable but there doesn't seem to be a method called "detectAndSendChanges()", or anything similar

FIXED IT 

 

	 @Override
 public void onUpdate(ItemStack stack, World world, Entity entity, int par4, boolean par5)
{
	if(stack.stackTagCompound == null && stack.itemID == ModResorces.decay.shiftedIndex){
		setWorldTimer(stack, world);
		return;
	}else if(stack.itemID != ModResorces.decay.shiftedIndex){
		return;
	}
	if(world.getTotalWorldTime() >= stack.stackTagCompound.getLong("EndTime"))
	{	
		stack.itemID = ModItems.adamantiumBucket.shiftedIndex;
		for(int i = 0; i < 36; i++){
			if (((EntityPlayer)entity).inventory.mainInventory[i] != null){
				if(((EntityPlayer)entity).inventory.mainInventory[i] == stack){
					((EntityPlayer)entity).inventory.mainInventory[i] = new ItemStack(Block.stone);
				}
			}
		}

	}else{
		stack.setItemDamage(201 - (int)(stack.stackTagCompound.getLong("EndTime") - world.getTotalWorldTime()));
	}
}

 

Not sure if the null check is needed, but it doesn't hurt to put it there, Thanks for putting me onto the track of looking at what i could do with the inventory

Thanks a tonne
