Constructor Details

RectCollider

public RectCollider(String id,
 GameObject o,
 double w,
 double h)

initializes this RectCollider. calls superclass constructor of Collider(String, GameObject) with params String id and GameObject o.

Parameters:

id - String unique name for this RectCollider

o - GameObject instance this RectCollider belongs to (cannot be null)

w - width in pixels for the collider dimensions (> 0)

h - height in pixels for the collider dimensions (>0)

Method Details

toString

public String toString()

Overrides:

toString in class Collider

checkCollisionRectRect

public boolean checkCollisionRectRect(Collider other)

checks collision with other Collider, which needs to be a RectCollider, too.

Parameters:

other - RectCollider (is casted) to calculate collision with

Returns:

true if collission is detected

checkCollisionRectCirc

public boolean checkCollisionRectCirc(Collider other)

checks collision with other Collider, which needs to be a CircleCollider

Parameters:

other - CircleCollider (is casted) to calculate collision with

Returns:

true if collission is detected

collidesWith

public boolean collidesWith(Collider other)

Description copied from class: Collider

checks the collission with another collider instance.

Specified by:

collidesWith in class Collider

Parameters:

other - the instance to compare to

Returns:

true if the colliders collide (touch or overlap)
