How to Have a Rigid Body Gain Forward Speed when Dropped?

Questions & Answers
1

Hey everybody.

Here’s what I’m trying to achieve.

What’s the best way to have a rigid body gain forward speed when being dropped from height? So, for example if you just had a cube and dropped it, it would start to move forward, gaining forward speed with a nice smooth transition?

Any ideas?

Thanks in advance.

Add a velocity to it, Lerping it from 0 to Your max value:

private float SmoothConst=0.3f;
private float MaxSpeed=10f;
public Rigidbody MyCube;


void Update{
if (MyCubeIsFallingCondition){
     MyCube.velocity = new Vector3(0 ,0 ,Mathf.Lerp(MyCube.velocity.z,MaxSpeed, Time.deltaTime*SmoothConst));
}
}

Note, that if it already is moving it will gain speed beginning with its current speed, othervise it will start from 0 velocity.
