Hardly a tutorial, without the triggers it's about 20 lines.

All you are doing is showing us some triggers. Try and explain them more.

• Events
  • Unit - A unit enters Region 004 <gen>
  • Conditions
    • (Owner of (Entering unit)) Equal to Player 2 (Blue)
  • Actions
    • Set tmpPoint = (Center of Region 001 <gen>)
    • Unit - Order (Entering unit) to Move To tmpPoint
    • Custom script: call RemovLoaction (udg_tmpPoint)

I'm happy to graveyard this simply because basic mazing allows this pathing to be screwed up. I'd hate to play a TD where this is implemented, and the order of where units go can be bugged, it's really disappointing.

Please update it with attaching the unit's next enterable rect to the unit, for starters...
(As well as removing the leak mentioned.)

All these leaks are just horrible. Anyways, i believe there is a TD tutorial MUCH better than this one.
