[Trigger] Help with Leaks and Locations

[Uklabokalala]

I tried to make a Trigger that at the time 20 in-game, 6 creatures called Forgotten spawn randomly on the map. I did it, but it was extremely simple and it leaked, so I (For the first time) decided to fix the leaks, but now the Forgotten just spawn in the centre of the map.

Does anyone know how to fix or make a trigger that'll spawn Forgotten randomly around the map that is leak-less?

(Playable map area) is actually a region that is initialized once at the start of the game. You don't need to remove that rect, you can keep reusing it.

However, (Random point in <rect>) does leak. Most points (also known as "locations") will leak if you do not clear them manually. Here is an example of how to do it:

• For each (Integer A) from 1 to 6, do (Actions)
  • Loop - Actions
    • Set Random_Point = (Random point in (Playable map area))
    • Unit - Create 1 Forgotten for Neutral Hostile at Random_Point facing Default building facing degrees
    • Custom script: call RemoveLocation(udg_Random_Point)

Here is a great reference for memory leaks:

Thank you! So much. Could I ask you if triggers similar to this one don't work?

Also when you destroy the Variable (In a sense) you said to RemoveLocation, but when I tried to save the map, it said it can't be converted to Rect. Should I change Location to Rect?

Feel free to ask. You can post any faulty triggers here and we'll help you patch 'em up.

As for your second question, make sure to make a variable: "Random_Point" of type Point, not region.
