Hi. Because its almost the same question... Heres a simple ( but well working...i guess ^^ ) 3rd person cam controller which takes care of walls and obstacles via c_trace. Maybe u need to play around with campos1 and campos2 values to fit ur needs. Thanks to SuperKu, cause he provited me the required tips for the c_trace part a few month ago. If uve optimized something, POST U MISER(S) ! 
// 3rd person cam controller written by rayp 2013
// -------------------------------------------------------------------------------------------------------------------------------------------------
var cam_lerp = 0; // global!
void _handle_cam_3rdperson(){
VECTOR cam_pos1,cam_pos2;
var i;
// -------------------------------------------------------------------
vec_set(cam_pos1,vector(-300, 0, 5)); // First cam pos
vec_rotate(cam_pos1,vector(player.pan,camera.tilt-15,0));
vec_add(cam_pos1,player.x);
// -------------------------------------------------------------------
vec_set(cam_pos2,vector(-20, 0, 30)); // Second cam pos
vec_rotate(cam_pos2,vector(player.pan,-5,0));
vec_add(cam_pos2,player.x);
// -------------------------------------------------------------------
//if u handle cam tilt/pan + playerpan somewhere else remove the following four lines. Its pan and tilt handling, not more.
//turn player via mouse mickey.x
c_rotate(me, vector(-mickey.x * time_step / 4,0,0), IGNORE_ME | IGNORE_PASSABLE | IGNORE_SPRITES | USE_POLYGON | GLIDE);
//set cam pan 2 player pan
camera.pan = my.pan;
camera.tilt += mickey.y * time_step;
camera.tilt = clamp (camera.tilt, -45, 45); //not tested play around with the values here
// -------------------------------------------------------------------
trace_mode = IGNORE_ME | IGNORE_PASSABLE | IGNORE_SPRITES | USE_POLYGON;
c_ignore (1, 0); // cam ignores the player
i = c_trace(cam_pos2,cam_pos1, trace_mode); //trace from campos to campos
if(!trace_hit) i = 1;
else i = i/vec_dist(cam_pos1,cam_pos2);
if (i < 0.1) set (player, TRANSLUCENT); //very close to player? set him transparent
else reset(player, TRANSLUCENT); //far away reset transparent
// -------------------------------------------------------------------
//calculate camera pos
i = i / 3;
cam_lerp = minv(cam_lerp+0.125*time_step,i);
vec_lerp(camera.x,cam_pos2,cam_pos1,cam_lerp);//at the end set camera x
}
// -------------------------------------------------------------------------------------------------------------------------------------------------
Example call in your project
void move_player(){
player = me;
my.group = 1;
...
..
while (1){
...
..
c_move()
_handle_cam_3rdperson();
..
...
wait (1);
}
..
...
}
...when copy and pasting at least credits would be nice edit: Its not good to turn player via c_rotate ( dont know why i wrote it in the code ). Use "player.pan += ..." instead. When using c_rotate, player will stuck while looking around, in some situations.
