How to move a unit towards another

Hi, the ability im making involves some kind of blackhole that drains units nearby. so here is my question

how do i make a unit, move towards the caster by 10 every .1 second?

Well, first create a custom black hole unit. Then go to Stats- Movement Base and change it to something really high. Then you might use a trigger like this:

Black Hole Trigger
Events-
?Unit uses ability/casts spell?
Conditions-
Boolean Comparison: Ability = black hole spell equal to true
Actions-
Create unit: custom black hole unit
Issue Unit Order Targeting a Unit: Order (Last Created Unit) to attack
(?targeted unit?)

I'm not sure if this helps, but if not maybe someone can run with my idea to make it work. Or maybe this is all the help you need. :god_help_us:
