Hello.
I have a platformer character and a jump through platform object on the scene. I have placed the character right above the platform. It is supposed to land on the platform but it is not landing. What could be the possible reason? I have checked the collision masks and they are fine.
I think you are right. I did the test here using the grid 64x64 to position the objects in the scene (they are 64x64 and the platform have type “Jumpthru platform”):
The result is:
I believe it is a bug. But a workaround is if you place your character 1pixel up it won’t pass through.
