how do i fix that code so i get it like a crate

Code:
___________________________________________________________________

var earthgravity[3] = 0,0, -300; // The amount of Gravity Force
entity* boulderm;

action obelisk //If You Own Commercial Edition, keep the action like this
{
wait(1);
}

action obelisk //If You Own Professional Edition, keep the action like this
{
phent_settype(my, PH_RIGID, PH_poly); // sets the object within the physics engine
ph_setgravity ( earthgravity );
phent_setmass(my, 120, PH_BOX);
phent_setfriction(my,7);
phent_setelasticity(my, 10, 10);
}
