Hi!
I can anybody help me?
I want to shoot down some water drop models with a beam of light. I have the light beam as a model too and this appears if i press Spacebar:

// Light beam OFF
if(!key_space){
set(my, TRANSLUCENT);
my.alpha = 0;
}

// Light beam ON
if(key_space){
reset(my, TRANSLUCENT);
my.alpha = 100;
}

Now my problem is, that if a light of beam is OFF, the water drop modells cannot go through them & encounter with them. How can I code it, that the water drop modells ignore the light beam, if this is OFF and go through, so as if there would be nothing?

I don`t know exactly what you mean. Maybe this?

...
set(my,TRANSLUCENT | PASSABLE);
...
...
reset(my,TRANSLUCENT | PASSABLE);
