Hi! How can I get the player name that placed a block?

If it is a custom block, in the block class, override onBlockPlacedBy, it has EntityLivingBase argument, check if instance of EntityPlayer, cast it to EntityPlayer and then do getDisplayName().

 

If it is a vanilla block it is more complicated, I'm not sure how its done but I suggest looking at PlayerItemUseEvent.Tick.

Thanks!

I've done it like this:

@Override
    public void onBlockPlacedBy(World world, int par2, int par3, int par4, EntityLivingBase entity, ItemStack itemstack) {
        if(entity instanceof EntityPlayer){
            EntityPlayer player = (EntityPlayer) entity;
            PlayerName = player.getDisplayName();
        }
    }
