I have a simple version of bump that handles collision. The code is literally your example except just modified to handle the new movement. I can probably provide a simple tutorial about how to make sure a layer is collidable. It's no much but it does do the "how do I make sure that the person stays within the collision area".

Later one I'm planning on doing "teleporting" and other items if I can figure it out, I was going to go with box2d and use a collision callback but for the initial prototype I'm using bump. I don't know if a simple tutorial about just using the map shown in the screenshot and handling player movement would be wortwhwhile or not here.

I actually have a collision layer that's set to 0 opacity currently to keep things simple as I learn STI/bump.

OK then I'll try to writeup the bump movement tutorial since it looked like there was an issue exactly about that after I get my nursing homework for the day done tomorrow. I'll try to do a series with it as I learn more, do more of the basic things until someone can basically do all of the basic tiling stuff that's required for them to make the world map with collision and teleporting points and the like. I do think having a seperate repo with the assets would be a good idea so that you're not cluttering up your git repo with lots of sprite sheets and the like.

One thing I'm hoping to do with the dawnlike tileset is actually do the background tile animation but that I'm not sure how it'd be done tiled w/o either a) swapping out the atlas or switching visibility on a layer to get the animation effect.

Something like that gif but done in Love2d and using STI as in the animation-y effects.
