I have a creative tab but I want the blocks in that creative tab switch every 5 seconds to another block from that creative tab. The creative tab that I want to edit it mine and the blocks are mine too. Help is apriciated

The icon is controlled by

CreativeTab#getIconItemStack

. You should create your own

ItemStack

field and imitate the super method's behaviour using this field. Override

CreativeTabs#getTabIconItem

to return the next

Item

in the sequence.

 

Subscribe to

ClientTickEvent

, check the

Phase

and increment a tick counter. Once it reaches 5 seconds, set the

ItemStack

field to

null

, allowing the next

CreativeTab#getIconItemStack

call to cache the next item.
