You'll be forgiven. I don't think that this is going to be a copy&paste Lib because of it's size. I already reached an amount of effects, which would take a long time to copy & paste. And to make it even more friendly to use, there a secure mechanism if you work with entities on the effects. You can spawn entities with a lifetime and they will be removed after that time. And in case the server shuts down before the expiration, the entities are remove instantly to prevent damage to the world. This is the reason, why you have to register an EventManager when using it. Disposing this manager kills all your effects immediatly.
