Passive spell that spawns units like pocket factory

[Nappe]

Is there any simple way to make a passive spell for hero that would spawn a permanent summoned unit every X second interval? Like pocket factory, except on the position of the hero. The spell should also have a cap of summons, for example when it has spawned 5 units they stop spawning.

Easy. Define a dummy unit with Locust ability, no model, flying, no shadow and no attack.

Make a pocket factory skill that costs 0 mana. It's cleaner if you make it a unit ability (untick hero ability).

Make a passive ability bereft of all its own stats, named for your mass pocket factory ability.

And finally make a trigger that creates your dummies on top of the unit with the passive, orders them to summon pocket factories at the desired locations, and removes them from the game. For a passive, a trigger firing every x seconds seems most appropriate.

I hope this will help you. I included how to change the limit of summons, the ability used, the duration of the summons (remove it if permanent), the delay between each summon spawn and the unit summoned.
Note : this is not MUI or MPI but I can do it, if you require

Just make a periodic time event that picks all units with the ability, and creates a summoned unit at their position. To limit the amount of summons, you should save the current amount of summoned units for the casting unit with an indexer and an array or a hashtable.

Interestingly enough, you can give any unit the ability Factory (which is the ability used by the Pocket Factory building itself) and it will periodically summon units.

You'd have to trigger the ability, as explained by previous posters, if you want to limit the number of summons per hero, though.
