Automatically wrap tile map

[wjt]

Take a look at level 1.tscn:

Notice that the platform extends 1 cell outside the boundary of the world on each side.

This is because Godot's physics engine (for the player) and raycast (for the goober) is not aware that the world wraps around. Without the extra cells of platform, the game does still work in this case, but if you look really closely you can see the player start to fall for a frame before they get wrapped around to the other side.

On this level my daughter made:

You can get stuck in the floor by jumping from the star at the top-right of the level, wrapping around to the bottom-right:

The level designer can work around it but I think it might be kinder to make the code that loads the tile map automatically do this wrapping.

Is this something easy to fix quickly? If not let's at least initially document this as a strong suggestion for level design.

I think it should be quite easy to fix.

I see it's already in the README until we get to a better fix. Thanks!

Is there any reason why there is a border of those circular things around the edge, invisible once you play the game (because they are offscreen?)
Looks like they are from the explosions tiles?

[wjt]

AFAICT they have no function, I think they're just a guide for the level designer as to where the edges are.
