Create the relevant physics layer in the tile definitions and assign collision polygons to the tiles that should block movement. The TileSet editor supports applying properties to multiple tiles, which helps keep related wall variants consistent. [3]\n\nFor the village, review doorways and wall corners with collision shapes visible. A decorative roof layer should not accidentally block a path because its tiles inherited an unsuitable collision definition. Check both the chosen definition and whether collision is enabled on the layer. Visual terrain connectivity alone does not establish gameplay passability.
