I'm getting artifacts on the edges around an animation frame.




On the left is from in-game. On the right is the original image. Notice the fuzzy edges around the character and the vertical pixels along the right edge of the frame. My setup and virtual resolution sizes match and I've carefully gone over the original sprite to make sure those were some tiny artifacts that got left in. Is there some kind of texture setting? It looks like it's scaling my sprite.


Here's the loading code:

If your images touch the edges of the defined spaces allowed for them, you may see some overlap.

It is a good idea to have at least one pixel along all edges that is transparent.

Can you show us the chipmonk2.png?

Here's the image:

If possible, you could disable filtering, so pixelated, but it looks like that might suit the style anyway. I'm sure you can adjust the UV border on a sprite as well though. Lemme have a quick look at the help files...


SetSpriteUVBorder

Description

Controls how the sprite handles UVs that might extend beyond the bounds of the image during sampling, for example when the edge of the sprite is halfway across a pixel. By default (border=0.5) the sprite compensates for this by offsetting UV coords by 0.5 pixels inwards, however this means that the outer most pixels of the sprite's image may not show. border=0 removes this offset creating a pixel perfect reproduction of the image, but this may cause texture seams when trying to line up sprites of the same image that don't fall exactly on a whole pixel. Setting the border to 0 may also cause animated sprites, or sprites using a texture atlas, to 'steal' pixels from neighbouring images. You may also increase this effect by setting the border greater than 0.5 pixels.

SetSpriteUVBorder( iSpriteIndex, border )




Parameters
•iSpriteIndex - The ID of the sprite to modify.
•border - 0=half pixel offset, 1=no pixel offset

While that command didn't help, you pointed me in the right direction now that I know what's causing it. My character position and speed are stored as floats for smoother movement and to manage acceleration. So I've used round() on the values when setting the sprite's position and that's corrected the problem.

I think you may have been able to use SetSpriteSnap as well.
