Sorry for the misunderstanding, basicially, every tile which you can see there has a simple collision which fits the -shaped tile. So to the right you see how the map is designed with the isometric viewmode. The problem I encountered is that If I walk with my character on the tile map (as I said, the right one is how it looks in the level), I can walk on the air, and I fall through the left part of the tile map, so I visualized the collision in the viewport, and you can see that the collision doesn’t match with the tile geometry, but with the orthographic viewmode => The collision doesn’t change on isometric viewmode, but it should. I hope that was clear
