I use thisRigidbody.rigidbody.AddForce(90, -90, -90);
to move a gameobject in a certain direction.
However, the default speed of moving is too fast.
How should I reduce its speed of movement?
Can I use ForceMode to control it?
Add less force.
Yeah, each of those numbers you’re putting in there is a force along a particular axis, which is why you’re getting a lot of it! Just back your numbers off and you should be fine.
