toString in class Collider

checkCollisionCircCirc

public boolean checkCollisionCircCirc(Collider _c2)
                               throws Exception

calculates the collission of this with other collider

Parameters:

_c2 - the other collider

Returns:

true if a collision was detected

Throws:

Exception - in case the math operations are invalid (due to illegal values of x y or radius)

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)
