Cosine / Sine Motion Paths

hi, i don't know what do u

hi,
i don't know what do u want exactelly but, try this and i hope it will help u to start:

select u'r object, go to motion panel in Command pannel,then assign to his position controller a position-scipt by clicking on the small button "?" left of the screen. go to properties of the position and paste this:

---------------------------------------------------------
--verify if the varriable "my_angle" & "my_radius" exist
--and creat them if not
if (my_angle==Undefined) do (my_angle=0.0;)
if (my_radius==Undefined) do (my_radius=10.0;)
--loop "my_angle" to avoid infinitiv incrimentation
if (my_angle>=360) do (my_angle=0)
--incrimentation of "my_angle" wich can be the speed
my_angle+=1;
--u'r function
z_position=my_radius*(cos my_angle)
--object position
[ 0, 0, z_position ]
----------------------------------------------------------

then press evaluate, play the animation, u'r object should float .hope u get what u want !!!
