# How does the rigidbody 2d work?

While the physics engine 2D moves colliders and makes them interact with each other, the Rigidbody 2D component is in charge of the communication of these movements with the Transform components. In this way the Gameobject will change according to the collider!

### How do i make "Trigger 2D" work!?

I added a Rigidbody 2D and it worked right away. Must have missed that somehow. Also i agree, the tutorial is a bit fuzzy about that you need a rigidbody to make triggers work.

How Exactly does Rigbody.AddForce Work? I kind of understand how to use Rigidbody.AddForce: changing the floating points in the vector3 variables changes how fast an object moves in the relevant direction. This is about how much the API explains, and it's adequate enough for a basic understanding of how to add a force to an object. But the API doesn't really explain how it works.

How do I apply a force in a RigidBody2D? Why use a RigidBody when you could use a KinematicBody for the ball, and a StaticBody for the blocks? commented Dec 1, 2018 by SIsilicon (3,844 points) reply. 1 Answer. 0 votes . I think what you need, if i did not missundertood, is to set the bounce property to non-zero value (this property can be set from inpector). if you want the ball to

### How to Setup your characters 2D Colliders in Unity – John ?

Creating a PhysicalMaterial for a 2D game is easy, just right click in your project panel, and select create > Physical 2D Material . Give the Physical2D material a name like ‘Slippery’ then double click it and lower the friction settings to 0.

Wwise with Unity Rigidbody 2d or Collider 2d? Wwise with Unity Rigidbody 2d or Collider 2d. Ask Question Asked 5 years ago. I'm half way in making a 2D game in Unity and found that Wwise needed the game objects to have a normal 3D RigidBody, since that's quite some work to replace everything, is there any way around? unity rigidbody wwise. Share.

Why does ForceMode.VelocityChange work but not Rigidbody ? The rigidbody will retain any existing momentum it received from velocity changes and forces it received previously. However, in your case it does not, because you overwrite the velocity in every update, causing the rigidbody to "forget" any previous forces and velocity changes.

### How to properly move Rigidbody2d in kinematic mode ?

Hi, I want to switch the behaviour of a Rigidbody2d node from kinematic to rigid and vice versa. Currently I am trying out 3.1 beta2. What confuses me however, is how to properly move the rigidbody

How does "Rigidbody2D.Cast()" works? This is what makes the Unity Documentation useful: Documentation for Rigidbody2D.Cast Basically it takes all the 2D colliders attached to the same object as your Rigid Body and projects them all forward in the direction you give and returns anything they hit.

Does using Rigidbody2D for a top-down Zelda style game ? Hi there, I'm pretty new to all this, but I'm starting to work on a 2D top down game in the style of Link to the Past. I've been coming up with ideas and a schedule for myself and as I set up the project I've run into an issue: I feel like Rigidbody2D isn't the best choice for this, but I'm not sure what my alternative is.
