All objects with a rigidbody are affected by gravity, if set up like in the Manual. Remove the script and make sure you have the checkbox named Use Gravity ticked in the inspector for the gameobject you want to have using gravity.

  • The game object that has 'other' must have a Rigidbody

  • The Rigidbody on other must not be kinematic (IsKinematic flag should be off).

  • Make sure 'other' is the game object you expect by doing Debug.Log(other.name).

  • It is possible the rigidbody is sleeping. Add this line to your code below line 3:


    other.attachedRigidbody.WakeUp();
