physics engine bug

[Maa2007]

this is the first time I'm using physics engine, however i think i have a bug or something here
i followed an online tutorial and everything worked right for me

i copied the same thing into my game, but for some reason when i activate the physics world
physics_world_create(1/10)

all moving objects in my room stop moving and stay stationary,
i have snow objects, and moving environment and steam, all of them stopped moving on x and y,

also my physics objects i put in the level are also not reacting and stay stationary

How are you moving the objects? Using the standard x and y values won't work, you need to use forces or (not recommended for most situations) manually update the position using phy_position_x and phy_position_y

other objects in the level are not using physics, (use physics check box is not checked in their properties ) so why should i use phy_position_x and phy_position_y ?
