[1.7.2] How to have an item's texture change while holding

[AimeryCM]

I am a pretty new modder and was wondering what to use to make a custom item (a pickaxe) to change texture while it is being held, like how vanilla minecraft's fire works while in the player's inventory.

 

Thanks!

Update to 1.10.2, 1.7 is ancient.

Fire is just an animated texture, any icon can be animated, just google how to create them.

Didnt Realize it was just a texture thing, not a programming thing. Thanks.

 

P.S. I am using 1.7 because it is the minecraft that i got to know and what most modpacks run on.
