Code: [Select]

_dir = random 360;
unit_name domove [(getpos player select 0) + (50*sin(_dir)), (getpos player select 1) + (50*cos(_dir))];
or something like that.

Code: [Select]

_unit = _this select 0;
_target = _this select 1;
_radius = _this select 2;

_ang = random 360;
_rad = random _radius;
_pos = [(getPos _target select 0)+sin(_ang)*_rad, (getPos _target select 1)+cos(_ang)*_rad, 0];
_unit move _pos;

EDIT:

and u cud even do it in just 1 line ... like

unitname domove [(getpos player select 0) + (random 50) - (random 50),(getpos player select 1) + (random 50) - (random 50),0]
