Close GUI on Block break


aadeg

Recommended Posts

Hi, in my mod I want to do a custom chest. So I create the block, the tileentity, the container and the GUI following the tutorial in the wiki. My problem is that if someone breaks the block (chest) while someone else has the gui of the chest open, the gui doesn't close. This bug can be use to duplicate items because, after the breaking of the chest, the items in it will be droped, but you can either pick up the items in the gui even if the chest is broken.

 

If someone could help, it will be great. Thank you very mush in advance.

Mh... I still have the problem.

 

In the tile class I put this:

public boolean isUseableByPlayer(EntityPlayer par1EntityPlayer) {
    	return this.worldObj.getTileEntity(this.xCoord, this.yCoord, this.zCoord) == this && par1EntityPlayer.getDistanceSq(this.xCoord + 0.5, this.yCoord + 0.5, this.zCoord + 0.5) < 64;
}

 

And in the Container class i put this, where chest is an instance of the type

public boolean canInteractWith(EntityPlayer par1EntityPlayer){
        return chest.isUseableByPlayer(par1EntityPlayer);
}

For the purposes of simplicity I said that the block is a custom chest, in real is a ChestShop that allow to anyone to buy and sell an item from someone. I wish that this thing doesn't change anything.

 

Here is the Block class
