Hai. Where did I go wrong?
It just does nothing at all.

Try removing this condition:

• (Terrain pathing at MM_TempPoint[2] of type Walkability is off) Equal to False

Apparently that pathing checking action is weird and I think I've heard that it actually returns the opposite. Anyways, that condition still won't work if there is some kind of an obstacle in the way, this just checks if the tile is generally unwalkable.

Anyways, that's the only thing that could cause nothing happening at all (as far as I can see atm).

Btw, a really minor thing, you don't need this:

• Set MM_Caster[MM_PlayerNumber] = No unit
• Set MM_Missile[MM_PlayerNumber] = No unit

Globals that are not nullified don't leak. But nice leak cleaning

Heh, I'll try changing that when I get home again

Because I really can't see what else would cause the problem
(That walkability thing was mostly to make the unit stop at pathing blockers.. ^^)

I know the importance of leak cleaning, therefore I'm trying to learn everything about it so that it comes automatically in the future :]

Try inserting a Game - Display text (or whatever it's called) here:

• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • (Terrain pathing at MM_TempPoint[2] of type Walkability is off) Equal to False
  • Then - Actions
    • Game - Display blabla

If the message isn't displayed when you test the map, then you know there's something wrong with the conditions.
