I have a model with an action: Code: action stroboscoop { while(1) { if(key_space == 1) { strobo(); } wait(1); } } And the following function: Code: function strobo() { vec_set(my.blue,vector(255,255,255)); if(key_space == 1) { while(1) { my.lightrange = 200; wait(-0.01); my.lightrange = 0; wait(-0.01); } } } When I press the spacebar the light will flicker. But when I release the spacebar the light continues flickering. Does anybody know how to stop that? So when I press the spacebar. The light will flicker as long the spacebar is pressed. When I release the spacebar, the flicker will stop. I hope you can help me out. Thanks in advance.

This is the code: Code: function strobo() { vec_set(my.blue,vector(255,255,255)); while(key_space) { my.lightrange = 200; wait(-0.01); my.lightrange = 0; wait(-0.01); } } action stroboscoop { while(1) { if(key_space == 1) { strobo(); } wait(1); } }
