[SOLVED] How do I allow objects to move relative to another object that's already moving?

One method is to use another (invisible) clone sprite, see this example:

Thanks! I think this could work. The only downside is you would essentially be playing two games at the same time since it's creating duplicative sprites and motion. This could impact performance. I like the logic though! I'll give it a try.

Well, it depends on the complexity of the game. If it's a simple motion (like Bullet or 8Direction), instead of the clone sprite you can use a couple of variables relX and relY. Then set the main sprite to table.X+relX, table.Y+relY

If you need Platform behavior or something like that, then I think the invisible clone is the best option..

You could also calculate the velocity of the Tilemap and use that instead of an extra sprite.

Ah yes! This is definitely a good way to handle things. Thank you both!
