I'm not sure there isn't any topic related with this bug, but if there is, i couldn't find it.

My problem is the following:

So, if i put reflective cubes and lasers together, quite strange things happen. You can get a cube from the middle of a tower for example without making the upper cube fall down. I don't really understand whats happening, so if someone could tell me how to solve this problem, i would be greatful, because i need this stuff working for my next test chamber.

Open the properties for the cube that will be removed from below the reflective ones and set this:

OnPlayerPickup > ["env_portal_laser" name here] > Turnoff
OnPlayerPickup > ["env_portal_laser" name here] > Turnon / after delay 0.15 sec

This way, the laser will stop for 0.15 secs and the reflective cube will fall instead of stay suspended in midair.

Try... I hope that helps

Even if you watch the laser when you pick up a cube, you can only see a little blink and if this method works fine with less delay too, even that won't be a problem. Thank you very much!

I was also helped with that and that's what I have to give!
