Does anyone know how I can get the turret to rotate to my mouse? Thanks for the help Rtsgamer706

So I added: action b_gun() { set(my,PASSABLE); while(my) { vec_for_vertex(me.x, basic, 365); vec_to_angle(my.pan,mouse_dir3d); wait(1); } } this works pretty well as the cannon does aim towards my mouse. The problem now is that the farther away my mouse is from the cannon the higher up it aims! Does anyone know how to lock the tilt and roll of the cannon or some other way to fix that problem? I already tried: my.tilt = clamp(my.tilt,0,0); and it doesn't work, =( Thanks for the help Rtsgamer706

You just must play with the numbers to set the right position.

When I added it to my original action or just told the gun to run it by itself, both times the gun just disappeared! Do you want me to put it after my original action, in my original action, should it replace my original action completely? thanks for the code, but how do I use it??? Rtsgamer706
