System information

Godot v4.4.dev - Windows 10.0.22631 - Multi-window, 2 monitors - OpenGL 3 (Compatibility) - NVIDIA GeForce RTX 3070 (NVIDIA; 32.0.15.6603) - AMD Ryzen 7 5800X3D 8-Core Processor (16 threads)

Issue description

Currently, TileSet physics layers do not have a collision_priority property, meaning that TileMapLayers always have a collision_property of 1.0, despite the fact that other Nodes allow the user to set this property. Being able to set this property is important for avoiding getting objects stuck inside the walls during depenetration.

Steps to reproduce

Just check the collision properties for TileSet physics layers:

Versus collision properties for CollisionObject2D:
