## Actions Documentation

### CalculateLocalInertia(number mass, Libraries.Compute.Vector3 inertia)

This action approximates the mass moment of inertia of a box relative to that box's local origin.

#### Parameters

### CalculateTemporalBoundingBox(Libraries.Game.Collision.PhysicsPosition3D currentTransform, Libraries.Compute.Vector3 linearVelocity, Libraries.Compute.Vector3 angularVelocity, number timeStep, Libraries.Game.BoundingBox temporalBoundingBox)

This action calculates the rectangular cube that will contain both the object in its position currently and also contain the object in a position after "timeStep" seconds from now.

#### Parameters

- Libraries.Game.Collision.PhysicsPosition3D
- Libraries.Compute.Vector3
- Libraries.Compute.Vector3
- Libraries.Game.BoundingBox

### Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

**Example Code**

```
Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)
```

#### Parameters

- Libraries.Language.Object: The object to compare to.

#### Return

integer: The Compare result, Smaller, Equal, or Larger.

### ComputeBoundingBox(Libraries.Game.BoundingBox boundingBox, Libraries.Game.Collision.PhysicsPosition3D transform)

This action finds the bounding box that would bound the Box in its current position.

#### Parameters

### Copy()

This action sets another box to have the properties of the current box.

#### Return

Libraries.Game.Collision.Shapes.CollisionShape3D:

### Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

**Example Code**

```
use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(t)
```

#### Parameters

- Libraries.Language.Object: The to be compared.

#### Return

boolean: True if the hash codes are equal and false if they are not equal.

#### Return

integer: The integer hash code of the object.
