Planes See through?!

[Amnesiaplayer]

Mmh, I don't remember too well, but I think the problem was the bodies not having something or not being attached to the mesh.

To be sure, try both functions on some entities, like a vase, a chair. When you find one that works, open two Model Editors, on one side the working entity that responds to the functions, on the other side your custom Alien entity. Now check the differences, how the bodies (green boxes) are set, each property and such.

In case your entity doesn't have a body, create one by first drawing a pink shape (then select it and click Create body). Then you wanna attach this body to the Alien. There's an Outline option for that, seek this info and attach the mesh to the new body. Copy the values from the other entity and see if it works.

About those white dots... there are a few solutions:

• Make one of the planes longer.
  
• Use black planes behind the walls.
  
• Use the editor's Grid Snapping to move/locate object on the plane (I see you have it enabled).
  
• Avoid decimal numbers on sizes/locations. If a plane is at x 71,003, set it to 71.
  
• If your level has no exterior, go to Level Options and set the skybox to pure black.
  

Thanks!
The plane thing is fixed now
But about the Alien, I didn't add a body to it, because it was supposed to do unknown appearance, at a distance, so you could never get in touch with it...
I did create a mini box in the middle of the alien, and gave it a body etc
