## Libraries.Game.Collision.BoundingBox2D Documentation

This class represents a 2D box that bounds an 2D item. The box approximates the size of the 2D items. The box is defined by two Vector2 objects which represent the maximum and minimum points of the item. This class is used throughout the Collision libraries to monitor collisions. The box is not allowed to rotate, therefore, we call these boxes "axis-aligned bounding boxes".

**Example Code**

```
use Libraries.Game.Collision.BoundingBox2D
use Libraries.Compute.Vector2
BoundingBox2D boundingBox
Vector2 minimum
Vector2 maximum
minimum:Set(-1, -1)
maximum:Set(1, 1)
boundingBox:Set(minimum, maximum)
output "The center of the bounding box is (" + boundingBox:GetCenterX()
+ ", " + boundingBox:GetCenterY() + ") "
```

## Actions Documentation

### CalculateDimensions()

This action re-calculates the center and the dimensions of the BoundingBox2D. This action is used internally. Note that center and dimensions are calculated when minimum and maximum are set.

### Clear()

This action will clear out the values of the BoundingBox2D, resetting all of its values to zero.

**Example Code**

```
use Libraries.Game.Collision.BoundingBox2D
use Libraries.Compute.Vector2
use Libraries.Containers.Array
BoundingBox2D boundingBox
Vector2 minimum
Vector2 maximum
minimum:Set(-1, -1)
maximum:Set(1, 1)
boundingBox:Set(minimum, maximum)
output "The box is centered at (" + boundingBox:GetCenterX()
+ ", " + boundingBox:GetCenterY() + ") with a width of "
+ boundingBox:GetWidth() + " and an height of " + boundingBox:GetHeight()
boundingBox:Clear()

+ ", " + boundingBox:GetCenterY() + ") with a width of "
+ boundingBox:GetWidth() + " and an height of " + boundingBox:GetHeight()
```

### Combine(Libraries.Game.Collision.BoundingBox2D box1, Libraries.Game.Collision.BoundingBox2D box2)

This action combines two given boundingBox to create the bounds of this BoundingBox2D. CalculateDimensions() should be called after this action to get center, width, and height.

**Example Code**

```
use Libraries.Game.Collision.BoundingBox2D
use Libraries.Compute.Vector2
use Libraries.Containers.Array
BoundingBox2D boundingBox
Vector2 minimum
Vector2 maximum
minimum:Set(-1, -1)
maximum:Set(1, 1)
boundingBox:Set(minimum, maximum)
output "The box is centered at (" + boundingBox:GetCenterX()
+ ", " + boundingBox:GetCenterY() + ") with a width of "
+ boundingBox:GetWidth() + " and an height of " + boundingBox:GetHeight()

#### Parameters

- Libraries.Game.Collision.BoundingBox2D: The first box to be combined
- Libraries.Game.Collision.BoundingBox2D: The second box to be combined

### 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.
