Implemented in: UnityEngine, unity rigidbody. Thank you for helping us improve the quality of Unity Documentation. Although we cannot accept all submissions, we do read each suggested change from our users and will make updates where applicable. For some reason your unity rigidbody change could not be submitted.

The main issue with the collisions in the last chapter was with the code. We are simply adding a value to the position, if the player is pressing a key. We need a way to make the player move in such a way that it reacts properly to boundaries and other GameObjects. To do so, we need to understand what rigidbodies are. Rigidbodies are components that allow a GameObject to react to real-time physics.

Unity rigidbody

Rigidbodies enable your GameObjects to act under the control of physics. The Rigidbody can receive forces and torque to make your objects move in a realistic way. Rigidbodies allow your GameObjects to act under control of the physics engine. This opens the gateway to realistic collisions, varied types of joints, and other very cool behaviors. Manipulating your GameObjects by adding forces to a Rigidbody creates a very different feel and look than adjusting the Transform Component directly. The biggest difference between manipulating the Transform versus the Rigidbody is the use of forces. Rigidbodies can receive forces and torque, but Transforms cannot. Transforms can be translated and rotated, but this is not the same as using physics. This is why you should only be using one or the other. Changing the Transform while using physics could cause problems with collisions and other calculations. Rigidbodies must be explicitly added to your GameObject before they will be affected by the physics engine. Now your object is physics-ready; it will fall under gravity and can receive forces via scripting, but you may need to add a Collider or a Joint to get it to behave exactly how you want. When an object is under physics control, it moves semi-independently of the way its transform parents move. If you move any parents, they will pull the Rigidbody child along with them. However, the Rigidbodies will still fall down due to gravity and react to collision events.

Use Discrete collision detection against dynamic Colliders with a Rigidbody and sweep-based continuous collision detection A collision detection method that calculates and resolves collisions over the entire physics simulation step. TryGetComponent Gets the component of the specified unity rigidbody, if it exists. Used for normal collisions This is the default value, unity rigidbody.

Rigidbodies enable your GameObjects The fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. More info See in Glossary to act under the control of physics. The Rigidbody can receive forces and torque to make your objects move in a realistic way. Any GameObject must contain a Rigidbody to be influenced by gravity, act under added forces via scripting, or interact with other objects through the NVIDIA PhysX physics engine A system that simulates aspects of physical systems so that objects can accelerate correctly and be affected by collisions, gravity and other forces. More info See in Glossary.

Rigidbodies can receive forces and torque, but Transforms cannot. Gets references to all components of type T on the same GameObject as the component specified. To control your Rigidbodies, you will primarily use scripts to add forces or torque. AddTorque Adds a torque to the rigidbody. We need a way to make the player move in such a way that it reacts properly to boundaries and other GameObjects. A GameObject can contain any number of components. Controls which degrees of freedom are allowed for the simulation of this Rigidbody. Now, playing the game will not show any visible difference, because the GameObject does not have anything to do with its physics component yet. Continuous collision detection is a feature to prevent fast-moving colliders from passing each other. Gets a reference to a component of type T on the same GameObject as the component specified, or any child of the GameObject.

Overrides Physics. With non-physical games, it doesn't make much difference if your models are all units long but when using physics, they will be treated as very large objects. The solverVelocityIterations affects how how accurately Rigidbody joints and collision contacts are resolved. Unity has many built-in components, and you can create your own by writing scripts that inherit from MonoBehaviour. Constraints Settings on Joint components which limit movement or rotation. Destroys the object obj immediately. Other colliders will use discrete collision detection when testing for collision against it. For these reasons it is always optimal to create your object at the correct scale in your modeling application. We are simply adding a value to the position, if the player is pressing a key. Collider-less Rigidbodies will simply pass through each other during physics simulation. Used to prevent fast moving objects from passing through other objects without detecting collisions A collision occurs when the physics engine detects that the colliders of two GameObjects make contact or overlap, when at least one has a Rigidbody component and is in motion. Tests if a rigidbody would collide with anything, if it was moved through the Scene. The typical solution is to use primitive Colliders for any objects that move, and Mesh Colliders for static background objects.
