[Custom Feature Question] Let's Go Features

Is there a way in Essentials to have the Let's Go catching mechanic, plus the ability to remove holding items and removing abilities from the game? If so, how?

haha you will have to dig a bit more by yourself man. Come with ideas and script you tried and everyone will help you correcting them but asking for how can I do something from 0 is a bit too much :p .I don't personaly know the "let's go catching mechanic" but I guess everything can be done. remove holding item can be done by copying the trick move or the thief ability for example

Okay, maybe I could edit the Safari Zone mechanic, so regular Poke Balls and Berries could be used, but I'm also looking to remove abilities and the ability to hold items entirely, I mean, I do have a vague idea to remove ability, by making an ability that does absolutely nothing and just not name it or anything.

Yeah, a do-nothing ability seems like a reasonable approach. You could also make sure no held items are in the game.
