FearLess Cheat Engine

Is there any way to change characters at will with cheat engine? You can search PL/2B as a string, but even if you change that, nothing happens.

Hello,

Is there any possible way to make a script that renders invisible walls in Nier: Automata? With any texture, or a pure color.
This would help a lot with glitch hunting.

I would appreciate any help to make this work.

Is there any possibility to actually detect in-game "triggers" with a script?
What I mean by triggers, are when your character moves to a certain spot/location and the game activates a game event and allows you to progress.
