Help with rpg game

Hello guys, I am new in creation of games and i m trying to make a rpg game, but i want to make a skill system, if the player bought some skill and add this to the action bar the animation of the skill should start when he press the key. But i don’t know how to do that… =(

Something like Cabal Online skill system
