[SOLVED] Calculate object speed?

Help & Support
#1

Hello :wave:,

I have 3d object which has rigidbody and moves according to force.
I want to calculate speed of this object.

I tried this.entity.rigidbody.linearVelocity but it is not working as expected.

How I can calculate object speed?
Thanks in Advance :pray:

Hi @Ketan_ATA,

One common way to get the speed per frame (per physics simulation tick), is to use the length() property:

const speed = this.entity.rigidbody.linearVelocity.length();

That will give you the amount of space the object will traverse in the next simulation tick.

Is is possible to do the same with length() for an individual axis?

You can do that by taking the absolute value on any axis:

const speedX = Math.abs(this.entity.rigidbody.linearVelocity.x);
