[Unsolved] Shooting Ability

So im using a Marine and im looking for like
how to make a shooting ability.
Such as make it as a shortkey and when he uses the ability he attacks.

Describe more detail (perhaps put it in a specific scene) and may be we can help you.

Attacks what? (the things in front of him?)

Is he supposed to have no normal attack?

More infos please...

'Trigger - Animations - Play animation (attack)'.

Well yes normal attacks.
and he should be able to attack enemies

Just play the animation, and create some 'bullet' dummy. Also, search in spells section for 'arrow' to find the arrow shooting system. Use it, and change the model to a bullet.

And please, read my signature.

or make a ability using dummy unit

event-unit start effect of ability(cast or something)
con-ability being cast (your ability)
act-create 1 dummy for owner of casting unit at position casting unit ..blah..blah..blah facing (facing of casting unit)
-add xx second expiration time to last created unit
-turn off colision for last created unit
-add DummyShoot ability to last created unit
-order last created unit to DummyShoot ability to facing of casting unit

(correct it if i'm wrong)
