### Operators

| Operator                                                                           | Description                                                             |
| ---------------------------------------------------------------------------------- | ----------------------------------------------------------------------- |
| [operator ==](/engine/6000.6/script-reference/unityengine/object/op-equality.md)   | Compares two object references to see if they refer to the same object. |
| [bool](/engine/6000.6/script-reference/unityengine/object/op-implicit.md)          | Determines whether the object exists.                                   |
| [operator !=](/engine/6000.6/script-reference/unityengine/object/op-inequality.md) | Compares if two objects refer to a different object.                    |
