Godot 4 TileSet one-way collision is not one-way only

[svprdga]

Godot version

v4.0.alpha.14.official

System information

Linux Mint, Vulkan

Issue description

When setting the collisions of a tile in a TileSet as one-way, the engine does not apply it correctly. Normally, a character should be able to jump to a higher platform from below "through" it, but any other type of collision should be detected and the engine should prevent the character from going through the obstacle.

In the code example that I attach you can see how the character can cross the area on his right. In this case, the character should hit that raised area and be stopped.

Steps to reproduce

1. Create a Godot 4 project
2. Create a map with a TileMap, and use a Tile with the one-way collision enabled
3. Add a CharacterBody2D node as the player, set its movement and collisions
4. Try to hit a tile from the side

This is not a bug. One way collision, as name implies, works only one way - from top. All other directions aren't detected; that's consistent with literally every platformer.

I suppose documentation should be modified to make this more explicit.

idk, I think the OP just confused it with "one way passage".

Right, I was confused about that. Thanks for the clarification.
