public class BoxCollider
extends Collider

A rectangular collider used for detecting collisions between box-shaped GameObject instances. This collider uses axis-aligned bounding box (AABB) intersection logic to determine overlaps with other BoxCollider instances.

Usage:

     MyGameObject gameObj = new MyGameObject();
     gameObj.addPhysicsComponent(new BoxCollider(gameObj, 1, 1));
 

You can also use GameManager to register and move Entity's:

     MyEntity entity = new MyEntity();
     entity.addPhysicsComponent(new BoxCollider(entity, 1, 1));
     gameManager.getGameRegister().registerEntity(entity);

     // update to new location.
     gameManager.getGameRegister().getPhysicsManager().tryMove(entity, newLoc);

Constructor Details

BoxCollider

public BoxCollider(GameObject owner,
 GameLocation originLocation,
 double width,
 double height)

Constructs a new BoxCollider for the given game object with the specified width and height.

Parameters:

owner - the GameObject that owns this collider

originLocation - the center point of the collider. (0.5 is half)

width - the width of the collider in world units (tileSize, so 1 is one tile)

height - the height of the collider in world units (tileSize, so 1 is one tile)

Method Details

intersects

public boolean intersects(Collider other)

Checks whether this collider intersects with another collider.

If the other collider is also a BoxCollider, an axis-aligned bounding box (AABB) intersection test is performed. If the other collider type is unsupported, this method returns false.

Specified by:

intersects in class Collider

Parameters:

other - the other collider to check intersection with

Returns:

true if the colliders intersect, false otherwise
