I can’t figure out how to add a constant velocity vector, a character should, like, magnetize to a wall or ceiling, add velocity to the ceiling so that if you touch the ceiling, the vector speed up, the character drops down, put more force than gravity does not help

  • Connect with a debugger and make sure that your conditions are met (your code is replete with magic constants - well, what can go wrong?;)). If everything is good, the object is updated, the forces are applied, then reduce your example to a minimum. Just an object that stretches to the object, without any checks on the type and button presses. Well, then using the method of half division, reveal the problem code. Successes. - Lunar Whisper

It must be something like ...

 private bool _wallIsTouched; Function FixedUpdate() { if(_wallIsTouched) rigidbody.AddForce(VectorToWall * Physics.gravity * rigidbody.mass) }

This code is written almost from Ponte) But the direction is exactly that.

  • You need to use ficsed update so that your acceleration does not skip when braking graphics,
  • need to use a rigidbody mass
  • and the level of gravity of the whole system so that the physics would not look adequately on the floor strange on the walls / ceiling

but you will need to remove the code yourself, since I broke
