One short line of code can despawn or spawn prefabs, or you can use our included Playmaker scripts! Pool Boss has been “battle tested” in our Core GameKit plugin which includes a much more powerful set of features and is a 5-star reviewed plugin.
Includes integrations for Playmaker, ORK Framework and Makinom! Now compatible with Bolt Visual Scripting!
Pool Boss works on Unity 5.2+, free and pro!
