I want to have at a start of a round that all chest in the world get filled.

But i have no idea how i should do this.

What is "at a start of a round"?

What are "all chests"?

 

I start the round with a command : /startRound

 

With all chest I mean all chests in the world.

 

So, you can say fill all chests in the world with a command

That's quite a performance hit, because you need to go through every block in the world, so thats like 30000000x256x30000000 blocks to check, check if they are a chest, get the chest TileEntity and fill the inventory with the items you want.

You mean all chests in loaded chunks? Because in unloaded chunks is basically impossible.

For loaded chunks you can use world.loadedTileEntityList to get all loaded TEs. Loop through them and you can filter out the chests.

 

Couldn't he create a list to which he adds.chest when they are placed?

This way he would be able to get all chests without having to loop through anything.

My code looks now so:

 

for(int j = 0; j < world.loadedTileEntityList.size(); j++)
	{
		TileEntity te = (TileEntity) world.loadedTileEntityList.get(j);

	}

 

but I don't know how to change now the Inventory

Thank you

It works now
