Limiting Unit summons

03-04-2006, 03:12 AM

Ok, I am creating a move called "Hunting Trap" and I am trying to place limits on the amount of traps you can create. The skills hunting trap itself is based off of the serpent ward summoning skill. The goal of these two triggers is to limit the amount of traps that can be cast, and if there are too many, remove the one created first (the one created longest ago). I am not sure why this is not working at this point....

(Another note: I have also added limitations so that if nets are summoned within 800 units of each other the first one created is removed)

Trigger:

Summon Trap Checks

Events

Unit - A unit Begins casting an ability

Conditions

(Ability being cast) Equal to Hunting Trap

Actions

Unit Group - Pick every unit in (Units within 800.00 of (Target point of ability being cast)) 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)) Equal to Deactivated Trap

Then - Actions

Unit - Kill (Picked unit)

Else - Actions

Do nothing

Unit - Kill TrapToDestroy[1]

For each (Integer A) from 1 to (Level of Hunting Trap for (Triggering unit)), do (Actions)

Loop - Actions

Set TrapToDestroy[(Integer A)] = TrapToDestroy[((Integer A) + 1)]

Trigger:

Summon Trap Checks 2

Events

Unit - A unit Finishes casting an ability

Conditions

(Ability being cast) Equal to Hunting Trap

Actions

Wait 2.00 game-time seconds

Unit Group - Pick every unit in (Units within 600.00 of (Target point of ability being cast)) 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)) Equal to Deactivated Trap

Then - Actions

Set TrapToDestroy[(Level of Hunting Trap for (Casting unit))] = (Picked unit)

Else - Actions

Do nothing

TaintedReality	After you have called a Wait in a trigger (your second one), the Target Point of Ability Being Cast variable is on longer stored. So, before the wait define a variable called TempPoint or something and set it to Target Point of Ability Being Cast, then use TempPoint after the wait.

SomeStranger	Thanks! I never realized that was the case. For anyone who cares or wants to do something like this in the future, I ended up combining the triggers into one. Turns out the the "Finishes casting an ability" does not always fire correctly if used right after the "Begins casting an ability" if the casting time of said ability is too short.
