Method Details

checkCollision

public static @Nullable MinimumTranslationVector checkCollision(Vector2D[] shapeA,
 Vector2D[] shapeB)

Checks for collisions between to shapes. If a collision is detected the MinimumTranslationVector will be returned. If no collision is found, then null will be returned.

Parameters:

shapeA - the first array of points for a shape to check collisions with

shapeB - the second array of points for a shape to check collisions with

Returns:

the MinimumTranslationVector if a collision was found or else null

checkCollision

public static @Nullable MinimumTranslationVector checkCollision(Vector2D[] shape,
 Vector2D circleCenter,
 float radius)

Checks for collisions between a shape and a circle. If a collision is detected the MinimumTranslationVector will be returned. If no collision is found, then null will be returned.

Parameters:

shape - the array of points for a shape to check collisions with

circleCenter - the circle center to check collisions with

radius - the circle radius to check collisions with

Returns:

the MinimumTranslationVector if a collision was found or else null
