Code: 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? Last edited by NeoNeper; 07/21/13 16:06. Please!

The problem is that he comes back and starts 180 sample: 1..2..160..180 \| -179...-169...-2 Last edited by NeoNeper; 07/21/13 16:22. Please!

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. Last edited by Malice; 07/21/13 17:09.
