How can i change the direction of my player without add a force

How can i change the direction of my player without add a force . I want to change the direction with one touch on the phone’s screen. The direction should only change between the forward direction and the right direction. I will be grateful for helping me…

Good day.

There are so many ways to move objects. Ading force is only one of them. You can change ist rigidbody.velocity or change directy its position with transform.translate, or changing transform.position.

Go read about them to see whats best for your project.
