hi. I don’t know the answer to your question. but if you aren’t use the center point of the object to something else (for example flip the object), you can change its position.
Sure but it’s a better practice to let the center point without touch because maybe later you need that point for something else in your game, if that is not the case then is perfectly accepted that yoou reposition the center point as you like.
Yes that’s a good point. But I don’t think that’ll cause any problem later, because now the center point is actually at the “center of gravity” of my soldier.
