this should work if you're using A6

Code:

---

action player_ent
{
 var input_vec[3];
 var Vz = 0;
 var jump_able = 1;
 camera.genius = me;
 while(1)
 {
  input_vec.x = (key_w - key_s) * time * 5;
  input_vec.y = (key_d - key_a) * time * -5;
  Vz += (Vz == 0) * 25 * key_space * jump_able;
  if(Vz > 0)
  {
  	jump_able = 0;
  }
  Vz -= (Vz > 0);
  my.pan -= mickey.x;
  camera.pan = my.pan;
  camera.tilt -= mickey.y;
  c_move(me,input_vec,nullvector,GLIDE);
  c_move(me,nullvector,vector(0,0,(Vz - 10) * time),0);
  if(trace_hit)
  {
  	jump_able = 1;
  }
  vec_set(camera.x,my.x);
  camera.z += 10;
  wait(1);
 }
}
