C# Class Nez.SubpixelFloat

simple helper class that manages a float value. It stores the value until the total accumulated is greater than 1. Once it exceeds 1 the value will be added on to amount when update is called. General usage would be something like the following. - calculate your objects velocity however you normally would - multiply by deltaTime to keep it framerate independent - pass the calculated delta movement for this frame to the SubpixelFloat.update method for both x and y. This will result in deltaMove being rounded to an int and the SubpixelFloat will deal with accumulating the excess value. var deltaMove = velocity * Time.deltaTime; _x.update( ref deltaMove.X ); _y.update( ref deltaMove.Y );

Public Methods

Method	Description
reset ( ) : void	resets the remainder to 0. Useful when an object collides with an immovable object. In that case you will want to zero out the subpixel remainder since it is null and void due to the collision.
update ( float &amount ) : void	increments remainder by amount, truncates the value to an int, stores off the new remainder and sets amount to the current value.
