From what I understand from vector maths, I trace from the camera position to (mouse_dir3d*distance + camera position). I've tried for about 2 hours now and I still can't get it to work and I've also tried searching the forums and it always gives me the same list of topics that are completely irrelevant! I am fuming! Please someone put me out of my misery and tell me how it's done. Here's my code: Code: if(mouse_left == 1) // left Mousebutton pressed? { mousetracertemp.x = vector(0,0,0); vec_add(mousetracertemp,mouse_dir3d); vec_scale(mousetracertemp,1000); vec_add(mousetracertemp,vector(camera.x,camera.y,camera.z)); printv("yep",c_trace(camera, mousetracertemp, USE_POLYGON \| IGNORE_ME)); ent_create("mcube.mdl",mousetracertemp,NULL); printv("x",mousetracertemp.x); printv("y",mousetracertemp.y); printv("z",mousetracertemp.z); while(mouse_left==1) wait(1); }

This is the code I use in my point&click adventure: pos2.x = mouse_pos.x; pos2.y = mouse_pos.y; pos2.z = 10000; vec_for_screen (pos2, camera); trace_mode = IGNORE_PASSABLE + IGNORE_PASSENTS + IGNORE_FLAG2; c_trace (camera.x, pos2, trace_mode); Now you can use 'target' to place your new entity.
