Recycle Dummy Units

[watermelon_1234]

I would like to know how to recycle dummy units for my spell, Whirlwind. Specifically, it's to recycle a unit with an ability similar to Slow Aura. The unit itself doesn't do anything except sit there.
I tried looking at the xe system to see how it did it recycled its units; it didn't really help me.

I'm thinking of using a group for this, but I'm not sure if that's the right approach to this.

Sorry if this has been answered before as the Search function didn't turn up anything for me.

This might help.

In your spell simply don't remove the dummy unit stored in the struct. Just hide it someway.
Then if the struct instance is used again, create a check if the struct member for the dummy is null.
If it is, create the unit, if not show the unit.

That is unefficent as it could mean a temporary high places units which never get recycled just cause there is a potential to be recycled.

If the units do nothing but sit there, consider making them into generic dummies and adding the slow aura via trigger for the spell (removing it afterwards). You then have a global dummy stack that you can reuse for multiple spells as needed. You use a stack system simlar to those group and timer recycling does which basically stores them in an array and takes the top one from it every time you need one and put it at the top every time you give it back. You can then also estimate how many dumy units you need (1 per spell casting player is a good guess) then pre generate them into it. Ultimatly though if the stack is empty you will need to make one so keep that in mind.

So whats different between this and TriggerHappy's idea? Well the system is prety simlar but the idea is to make its scope not just unique to your spell, as it would be more efficent if multiple spells used it as their dummy not just that one.

First of all, thanks to everyone providing something useful. =D

For now, I have decided to recycle dummy units the method TriggerHappy suggested.
