How do I "control physics"?

so i added physics as a behavior to a certain object and it started to move, how do i make it stop? i mean, i need physics for other stuff, but i dont want it to move like that

-thanks

You can set the the individual sprites physics settings to control the sprite you do not want to move. You can set "Immovable" on that object/sprite equal to "Yes" and that object wont be affected by your physics.

Those settings are also where you can control all the physics properties for that sprite/object and how it reacts to the global physics settings.
