I heve the 3D cordinates of the my mouse.
vec_set(mouse_pos,mouse_cursor);
target_from.x = mouse_pos.x;
target_from.y = mouse_pos.y;
target_from.z = 0;
vec_for_screen (target_from, camera);
target_to.x = mouse_pos.x;
target_to.y = mouse_pos.y;
target_to.z = mouse_range;
vec_for_screen (target_to, camera);
c_trace (target_from.x, target_to.x, IGNORE_ME | IGNORE_YOU | IGNORE_PASSENTS | IGNORE_MODELS | IGNORE_PASSABLE | USE_BOX); //vc_set (my.x, target.x); // and place the red target model to the proper spot on the terrain
vec_set(TARGET,target.x);
But now, I was wondering the angle of my mouse over an object. I tried many ways but I am not succeeding! Please could someone provide me a solution?

...
vec_set(tmp1,axys.x); //axys is the object
vec_sub(tmp1,TARGET); //TARGET is mouse position 3D
vec_to_angle(tmp2.pan,tmp1);
draw_text(_chr(str_for_num(NULL,tmp2.pan)),100,100,_vec(255,0,0));
in this example I made, I get close to getting! The problem is that he comes back and starts 180 sample: 1..2..160..180 | -179...-169...-2

My last post was wrong.. Try looking at the var trig functions there maybe something you can do with sin and cos but my math there is bad.. And if there isn't a simple way to shift this back to 0-360* range you might ask the developer for a function, but I am sure this can be done with simple math.

A simple logic solution is ..
vec_to_ang(tmp2.pan,tmp1);
if(sign(tmp2.pan) < 0)
tmp2.pan +=360;
if(sign(tmp2.tilt) < 0)
tmp2.tilt += 360;
if(sign(tmp2.roll) < 0 )
tmp2.roll += 360;
