Hi, I made my own block that gives you a random Item on right click, but there is a problem... The video shows the problem... http://deantonious.es/block.mp4

 

The Block code is this:

Thanks for the help

Hi

 

I think you need to force the server to update the player inventory on the client.  It's worth a try.

 

See vanilla code in BlockCauldron

 

if (!par1World.isRemote) {

  ((EntityPlayerMP)par5EntityPlayer).sendContainerToPlayer(par5EntityPlayer.inventoryContainer);

}

Thank you, it fixed my problem!
