Lines between tiled sprites

Hello everyone. I've searched the forums and I can find a few posts with similar issues concerning tiled backgrounds, but my issue is with animated sprite tiles. Keep in mind, I've only been putting it together for a few hours, so I know the art is rather terrible lol.

When I use the "run" command or the debug layout the animated tiled seem to look right, but when I export the game there is almost a transparent 1 pixel grid between each of the tiles. Here is a .png of the two side by side, I ran them at the same time on my dual monitors.

I've set fullscreen in browser to letterbox scale, the sampling to point and linear, turned on pixel rounding, and all my tiles are a power of 2, 16x16 I believe. It's odd to me that the animated tiles show this grid, but the wood tiles in the back do not, I guess because they aren't animated?

Anyway, here is a .capx for the file. Any advice you guys could give would be greatly appreciated.

just remove the words between the https:// and the dl. to get to the pic and file. Sorry about that guys.

If you want the smooth route (linear and no-rounding) then you need to change the coordinates or make the graphics 1 pixel wider/higher. Only way to reduce seams.

If you want to solve without that and don't mind stuttering then just change to point and rounding.

You need letterbox integer scale. The ordinary letterbox scale can use a floating-point scale which can show seams. Alternatively implement an overlap like — suggests.

Thanks for the quick responses you two. I'll try that when I get off work and it will probably fix it. Worst case scenario, I'll go back and add another line of pixels to the tile.

I'm curious though, shouldn't using a 16x16 tile along with a 16x16 or 8x8 snap-to-grid already make them seamless? They seem to work perfectly on the still frames, but not with the animated ones.
