[quote="newt":2z3miret]Also I guess somebody should mention that an addition to the sine behavior probably wont happen, since z(currently) is a sprite object dimension. It is the only object set up for it.
Not that you couldn't fake it for other objects.[/quote:2z3miret]
The SDK allows you to set the Z-elevation of any object, but it's up to the plugin developer to actually draw the objects with Z-elevation. Since the sprite is the object most commonly used with this behavior, it would be a helpful feature addition.
