![]() Well, for example, when you supply a Vector3 of (2,0,0), Unity will automatically convert this into the needed values. How does supplying only a position translate into a direction and speed? ![]() Unity’s implementation of velocity requires that it be assigned to a Vector3 value but as we know a Vector3 is just a position with X, Y, and Z coordinates. How Does the Rigidbody’s Velocity Affect Your GameObjects? Basically, for a GameObject to have velocity we must have a speed and a direction. The Wikipedia entry for Velocity states “Velocity is equivalent to a specification of an object’s speed and direction of motion”. According to Unity’s Documentation on Rigidbody.velocity, velocity “represents the rate of change of Rigidbody position”. There is no better place to start learning what something is than looking up the definition. What is Rigidbody Velocityįirst, if you want to know how to use something the right way, it is best to understand what it is. In this Tips and Tricks, we are going to talk about how you can assign velocity directly, what velocity means, and how it affects our GameObjects inside of Unity. ![]() When changing the velocity of your GameObjects it is recommended that you use Rigidbody.AddForce but there are circumstances where you may need to modify the velocity directly. You can assign it directly by using `Rigidbody.velocity = Vector3`or by using Rigidbody.AddForce. One of the most commonly used properties of Rigidbodies is velocity.įurthermore, you can set Rigidbody velocity in one of two ways. Unity comes with built in physics simulations which you can apply to your GameObjects through the use of Rigidbody components. When moving characters, vehicles, or other objects around your game physics quickly become an important factor.
