I was just wondering what is the best way to create one of those that works like professional apps. I've started developing a level editor for 3DGS Easy Scripter and so i want to make a good working gizmo. Right now i have 3 arrow models attached to the origin on a model, pointing in each direction. Would it be best to move it using events like EVENT_TOUCH together with mouse_force or would tracing from the camera be a better solution. I'm just interested in hearing your ideas. Thanks, DJB.

I thought mouse_pos3d gave you the 3D coordinate of the mouse, so i tried setting the entity's position to that but it flies to a random position. Are their any more examples of creating a transform gizmo?

Maybe, you could move an entity parallel to the view the following way: Code: function move_with_mouse() { VECTOR to; if(mouse_left&&mouse_ent) { set(mouse_ent, TRANSLUCENT); set(mouse_ent, LIGHT); vec_diff(to, mouse_ent.x, mouse_pos3d); vec_add(to,mouse_pos3d); vec_set(mouse_ent.x, to); } } http://www.puppenheim.org/ http://www.wuerfels-welt.de Old Game Tutorial: http://www.puppenheim.org/MITutorial.zip Free Game Editor: http://puppenheim.org/AlienalsWeihnachtsmann.zip http://www.puppenheim.org/blender_starting_main_settings.txt

Code: ENTITY* x_arrow; // x direction arrow attached to entity VECTOR to; while(1) { var distance = c_trace(player.x, x_arrow.x, IGNORE_ME); vec_set(to, mouse_dir3d); vec_scale(to, distance); vec_add(to, mouse_pos3d); x_arrow.x = to.x; wait(1); } ...just seems a little buggy.
