[Trigger] Summon Ability with unit cap

[GrimSloth]

Hello, I'd like to make a summon ability where the cap of units that can be summoned is fixed to the level of the ability.

So let's say the ability is level 4, then I can summon a maximum of 4 units. This is what I tried, and it initially works. However, when a summon dies, the ability will not always summon another unit. Sometimes all summons have to die until the ability works again, and it starts summoning.

If you have Summon Wolves from other sources they could be interfering. Also, dead units may cause problems like a corpse being picked up in the Unit Group but it looks like you check for that.

I would track the number of wolves with an Integer variable:

• Then - Actions
  • Unit - Create 1 Wolf Guard...
  • Set WolfCount = WolfCount + 1

• Events
  • Unit - A unit Dies
• Conditions
  • (Unit-type of (Triggering unit)) Equal to Wolf Guard
• Actions
  • Set WolfCount = WolfCount - 1

This variable will always be equal to the exact number of Wolf Guards assuming that your ability is the only way to create them. This design is Event driven which helps keep the data precise and accessible whenever you need it.

If this ability needs to work for multiple Players then you can make WolfCount an Array and use the Player Number of the Owner of the Wolf as the [index]. To make the ability work for any number of units owned by a player then you'll probably want to use a Hashtable.

Thanks! I'll give that a try


Edit: It works splendidly! Best of all, I wanted to include another summon ability, so I can technically keep a combination of both at 4, which was my initial goal
