# Collider

> A base class of all colliders.

## Definition

* **Type:** Class
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.PhysicsModule
* **Inherits from:** [Component](/engine/6000.7/script-reference/unityengine/component.md)

```csharp
public class Collider : Component
```

## Remarks

If the object with the Collider needs to be moved during gameplay then you should also attach a Rigidbody component to the object. The Rigidbody can be set to be kinematic if you don't want the object to have physical interaction with other objects.

### Operators

| Operator                                                                           | Description                                                             |
| ---------------------------------------------------------------------------------- | ----------------------------------------------------------------------- |
| [operator ==](/engine/6000.7/script-reference/unityengine/object/op-equality.md)   | Compares two object references to see if they refer to the same object. |
| [bool](/engine/6000.7/script-reference/unityengine/object/op-implicit.md)          | Determines whether the object exists.                                   |
| [operator !=](/engine/6000.7/script-reference/unityengine/object/op-inequality.md) | Compares if two objects refer to a different object.                    |
