Raids/Events

Issue description

Hello MCreator team,

This is a feature I have being dreaming for a long time, But would it be possible to make raids? I feel it would help grow moders on your system who want to create raids like Pillager raids. 

Issue comments

Designing whole raid system with definitions of types of mobs and raid parameters is a bit out of scope at the moment, but might be considered later down the road.

I really need this for "We must go deeper" for when rebels raid the order's outposts, if you have no clue what im saying check my page for the forum "We must go deeper"

I noticed something to help, go to the link here read the latest comment then instead of doing this thing on a mob do it on block and use the activator as tick update, put that block in the structure to be raided, choose entitys for the rade then boom, done
