Making enemy bullets

May I ask how to do in the best way, bullets that will spawn on front of the enemy which is a still target, and will move forwards until they hit a wall, or you and when they hit you or something they get destroyed, . just need to know how to spawn them on the first place and make them move in a downwards direction (because its 2D top down). dont need to show me everything just a bit of a heads up to help me understand better

If you create a new project of Firts Person Template. it has a projectile there very simple to use as you want.
