Random Region Conflict

[Radicool]

I am creating a system for a boss fight in my map. The "Infected Farmer" boss runs to a random region (Green rectangle). He then teleports to another random region (Green rectangle), leaving behind some zombies. He runs from this new region to the center region (Blue rectangle).

Two Problems:

1.) The Infected Farmer can teleport to a region that he teleported from giving the appearance that he never teleported at all. I need to make the Farmer teleport to any random region BUT NOT the region he was teleporting from.

2.) Does the timer leak at all? Read somewhere that it leaks.

Could I get some help please?

 

[Daffa]

1) You need to filter the region.
2) As far as I'm aware, no.

 

[Radicool]

1) You need to filter the region.

Can you explain? How can I do this?

2) As far as I'm aware, no.

Ok, that's good.

Know which rect has been entered/which rect the Farmer is supposed to move to first and ensure it's the one that triggers Infected Farmer Teleport. Save that rect in a variable, move the last element of the array to the index of the rolled rect. For selecting a rect to teleport to, only roll from 1 to 3 now. Afterwards put the previously cached rect on the last index of the array [4].

I could follow the first half of your instructions, but I got confused on how to compile 3 regions into the arrays. I've done it this way (although I'm sure there's a better way to do it):

I'm normally one to be satisfied with whatever dodgy system I make as long as it works and doesn't lag, lol. One question though. How do I clear the events within a trigger? I mean, the event "A unit enters region" is added to one of the triggers every time this runs. Theoretically, this can eventually lead to hundreds of events. Isn't this a form of leak (Redundant memory usage).

Yes, it leaks. And it would trigger on any rect entered. In GUI, you do not have an event response to get the triggered rect/region. You could either ask if the unit is within a rect that slightly surrounds the one in question (and that does not overlap with the other) when any is entered. Or you go jass and work with regions instead of GUI rects. Or you make separate triggers for each rect (you can still outsource the common actions in an extra trigger and execute it).

Instead of

• (Zombie 1 Spawn <gen> contains (Center of InfectedFarmerTempRegion1)) Equal to True

(which leaks a location btw), you could have simply saved the rolled index and compared that to fixed numbers.

 

[Daffa]

You can remove a trigger by deleting it.
using call DestroyTrigger()
