Tool player animations

[ArtexTuga]

Hi, i am trying to do a Naruto mod, and the jutsus(powers) will be items that, on right click, summon a fireball entity, make a stone wall etc..

I want  to do a Casting animation for the jutsus (handsigns), but i don't know how to do Player animations, the animation will play after the tool is right clicked

Can somebody explain me how to make player animations for tools?

Version: 1.7.10 (i am making this mod to match up with some other mods for my server modpack, that's why it is so outdated)
