Freezing Trap bot?

[Xkirito 1]

Is there a way to make a trap bot on focus target? I've found this
wManager.Wow.Helpers.ClickOnTerrain.Spell(1499, wManager.Wow.ObjectManager.ObjectManager.Me.FocusObj.Position);
but the problem is when i use this in fight class, it will spam the trap no matter what instead of using it when i press my freezing trap. So is there a way to run this code when i press freezing trap? I appreciate every help, ty for your time.

Kinda need to add your own logic.
