Code:

action basketball
{
	phent_settype (my, ph_rigid, ph_sphere);
        // you should place this code on the main function, but it works
	ph_setgravity (vector (0, 0, -386)); // play with this value   

	phent_setgroup (my, 3);
	phent_setmass (my, 0.624, ph_sphere); // play with this value
	phent_setfriction (my, 100);
	phent_setelasticity (my, 25, 0);
        // disable it for now, you must read this function on the manual
	//phent_setmaxspeed( my, 500, 500);  

	//wait (3); //what for?  
	while (player == null){wait (1);}
	while (1)
	{
		if (vec_dist (player.x, my.x) < 1000)
		{
			phent_enable(my,0);
			my.skill22=1;
			  //wait (1); //what for?
  		}
        wait(1);
        }
}

I ran a test and it works fine now. When the ball reaches 1000 quants to the player, it stops and stays disabled temporarly
