SpriteBase functions

Is there no way to push a sprite towards another sprite?  None that I can find, and it would be annoying to have to make a new plan for each level if you always wanted one sprite to gravitate towards another in all maps.  Of course, I understand that trying to implement this in the SpriteBase class would not be feasible for a specific sprite, but maybe for the nearest of the specified sprite definition, like in SGDK1?

There are a lot of rule types that have yet to be coded.  I think I want to get a first pass at the documentation done before getting back to some of the coding details.  In this case, I think it'd work best to have the sprite category be the parameter specifying which sprite to move toward, because a sprite category tracks a number of specific sprite instances.  If I were to look for a specific type of sprite, I'd probably have to loop through all the sprites in the layer since I don't track instances by definition type at this point.

A few more suggestions for later, when more rules are to be coded:

TestCollisionMask (or Rectangle) for two categories, such as "Enemies" and "Bullets", rather than a individually for each bullet or enemy against the other category, since you have to have each bullet defined separately.

A built-in function to activate when a sprite touches a tile of a specific type, rather than being within that tile.

Activating a sprite and put it at a location based on another sprite's location, rather than a tile (i.e. for bullets, again).
