hitTestObject

Performs a hit test for all sprites in the scene against a given screen point in pixels. Returns an array of Sprite objects that were hit.

isIntersectingboolean

Checks if two sprites are intersecting (overlapping). Always use this function or Sprite.intersects, don't develop your own intersection logic.

removeAllvoid

Removes and destroys all the sprites in the scene. You cannot reuse previously created sprites after this.

unitToPixelvec2

Converts between normalized unit coordinates where (0,0)=top-left and (1,1)=bottom-right to pixel coordinates (0,0)=top-left and (screenWidth,screenHeight)=bottom-right. Use this function to translate touch events coords received from the Touch Events block to pixel coordinates that Sprite Manager is operating in.

pixelToUnitvec2

Translates between screen pixel coordinates (0,0)=top-left and (screenWidth,screenHeight)=bottom-right into normalized unit coordinates where (0,0)=top-left and (1,1)=bottom-right.
