Right now I’m just loading a whole tiled tmx map into a SpriteMap and moving a camera around but this creates artifacts and shimmering/stuttering. How would you go about moving the camera around a tile map being displayed by a SpriteMap?

Also this will be the last time I contribute to this conversation now but, what you have been fighting with the “waves” is a sampling error caused by the fact its a plane in a 3d space. So sometimes there are fractional float values that get sloppy causing the “wave” that you are seeing. So to fix …

Its super hard to notice and might be isolated to your client for the most part. Id be able to help more if I could recreate, but there is little I can do just watching a recording. Odds are its your movement style that needs to be refined. Instead of doing whole numbers maybe incorporate a accel…

Alright I guess I’ll have to write my own.

I can give you a better example of movement and maybe that will fix up the problem you are having. I just really think its a timing issue with the movement and your refresh rates.

[image] Ok after changing the movement method I was able to control it a little better and see the effect you are. All the lines should stay straight, but its like its rounding some of the sampling depending on fractional values or something. So its looking more like a sampling problem, we might…

Yeah I think this would needed to be added, sounds like its the same thing. Ill have to figure out how to apply that to the spriteMap though it seems like it might be a little tougher to do because of how the UV is being split up essentially for the atlas. It will just take a little bit of thought…
