*IHasAABB2D* is an interface that allows for spatial hashing to be performed.
|
||
|
|
|
||
|
|
## Properties
|
||
|
|
|
||
|
|
##### **public AABB { get; }**
|
||
|
|
|
||
|
|
An axis-aligned bounding box for the shape. This is stored so we can efficiently transform the AABB when necessary.
|
||
|
|
|
||
|
|
##### **AABB TransformedAABB(Transform2D transform)**
|
||
|
|
|
||
|
|
A method which returns the axis-aligned bounding box for the transformed shape.
|
||
|
|
|
||
|
|
For example, the TransformedAABB method for Bonk's *Circle* implementation:
|
||
|
|
|
||
|
|
```cs
|
||
|
|
public AABB TransformedAABB(Transform2D Transform2D)
|
||
|
|
{
|
||
|
|
return AABB.Transformed(AABB, transform2D);
|
||
|
|
}
|
||
|
|
```
