I’m afraid I can’t help because I don’t understand.
Your title says without physics, your text says with physics, I don’t know what you mean in #1, and for #2, you seem to ask a question and give the answer.
Sorry, english is not my first language.
What I meant is that I am trying to make enemies with physics, so I want them to chase the player and take knowckback. “Provafisica” is an object with the physics and I want it to chase the player. I tried to apply the physics to the enemies but when I do they dont move. Can you help me?
