Methods
split () → {void}
Splits up the node into 4 equally sized nodes where each node corresponds to one quadrant of the original node. All objects from the original node are then put into the new node(s).
Parameters:
Name | Type | Description |
---|---|---|
otherBounds |
Array | The bounds of an Object |
- Source:
Returns:
- Type
- void
testBounds (otherBounds) → {bool}
Checks to see if the supplied otherBounds overlap with the bounds of the node that this method is called on.
Parameters:
Name | Type | Description |
---|---|---|
otherBounds |
Array | The bounds of an Object |
- Source:
Returns:
Returns true or false
- Type
- bool
getQuadrants (bounds) → {quadrants}
Checks the QNode’s children (if they exist) to see which quadrants the given bounds (from an object) fall in.
Parameters:
Name | Type | Description |
---|---|---|
bounds |
Array | The bounds of an Object |
- Source:
Returns:
Returns an array of indices of the nodes the bounds fall in [minX, minY, maxX, maxY]
- Type
- Array
clear () → {void}
Clears the node's object array and deletes
- Source:
Returns:
- Type
- void
_getObjectBounds (object) → {bounds}
Calculates the bounds of the given object since some methods in QNode needs to calculate this.
Parameters:
Name | Type | Description |
---|---|---|
object |
Object | Object to calculate bounds |
