Switching betwen Attack 1 and 2

Hey, I have a unit that has enabled attack one and two, i would like to make a dummy skill to be able to switch betwen them, so the player has attack one or two, but not both at the same time. It's one attack for ground units and the other for air.

Thanks!

...You totally realize a unit can't attack using both its attacks at the same time, right? If a unit has attack one and attack two enabled, it will use EITHER one or the other, but not both...

Perhaps I'm missing what you're saying, I don't see the application of turning the attack 1/2 off or on.

Yep i kno, but i want to add some kind of delay betwen switching the attacks, the unit is a tower with 2 animations one with the cannons pointing up, and the other with the cannons pointing down, and the player that uses the tower has to swtch in time to be able to kill air or ground units, i know i could use morph but im already using morph on that unit for another skill

You can do this:
Create unit X in OE with attack 1 enabled
Create unit Y in OE with attack 2 enabled

Then you can use the "Chaos" ability to morph unit X into unit Y.
