Shooting Cannon

[Question]

i want to make a cannon that shoots balls like a ball shooting tennis machine and is not player controlled and if u get hit u get damaged.
How can i do this?

a pretty easy, in a periodic trigger like every 1.5 time, order the created unit to cast some skill to target area, and the created unit is create when you cast the spell... i think will work, at least in my head work xP
