how do i make a painting moveable?

And how do i make it so the painting stick to the wall?

it falls down when i enter my cs

The trick is to make sure "Snap To Grid" is not checked; this allows for more precise movements of objects in the level editor. What you'll want make sure the painting is touching the wall, but also make sure the player can still see all of it (i.e. the wall behind the painting isn't pushing through the texture).

Basically, just make sure the frame is touching the wall, but the wall isn't going through the picture.
