Question by Bitpocketer · Mar 18, 2017 at 10:06 AM · physicsvelocityforcerigidbody.addforcescripting-underthehood

how to restrict velocity to specific magnitude when force applied equals rigid.mass * 9.8f to fly an object affected by gravity.

Hello how are you doing guys, i have got here a plane of mass 1450 having Drag 1 and angular drag 0.1, now what i'm doing actually is adding up force to the rigidbody in a way that the magnitude of the force equals the mass of rigidbody times 9.8f to make it fly, it does fly but it's too fast i want it to move in its forward direction with controlled velocity..

 float lift = rigid.mass  * 9.8f;
 Vector3 forcedirection=transform.forward;
 rigid.AddForce (forcedirection*lift);
 
 Vector3 velocity = rigid.velocity;
 velocity.y += 8f * Time.deltaTime;
 velocity.z+= transform.forward.z * 0.5f * Time.deltaTime;

with all that cofiguration, it does fly but it's faster and flies over terrain within 3 seconds which 1000x1000 in width and height, how do i reduce it's velocity?
