[General] How do I check if a point is within range of a unit with a certain unit type?

[Cobalt]

I have a trigger that requires checking whether a certain point is within X range of any unit of a specific unit type. More specifically I want to detect some kind of collision.

I've looked for an appropriate condition but I haven't been able to find anything. I tried playing around with the "Region - Region contains point" condition, but I haven't been able to figure anything out.

If possible a GUI solution would be ideal, but I'm open for JASS if it's required. Thanks in advance <3

This:

• Set POINT = Centre of (Map Area)
• Unit Group - Pick every unit in (Units within 512.00 of POINT) and do (Actions)
  • Loop - Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • Unit-type of Picked unit is equal to Footman
      • Then - Actions
        • Stuff
        • End loop
      • Else - Actions

Hope this helps!
