Removed the portalable ceiling. I'd never have seen some of these bugs without your help.

I don't think you should be able to suck through solid doors. The object doesn't go through the door, but the suction does. It felt like a bug to me. I think you should just make the ceiling above the door unportalable.

Thanks! I'll fix the first puzzle and one thing I noticed about the logiic gates is that you can only have 2 inputs each or things go crazy. The door is a good idea it would let you suck the cubes up or stop them, might have to change my Time-Limited Diversity" test from the draw bridges.

Diversity vents can suck through solid doors... try putting a portal on the ceiling between the door and the fizzler, and the cube in the first room will get sucked off the button and hover in the air against the door. Oh, and I skipped the first "puzzle" by jumping across the water and just picking up the cube.
I think this is very different from the mechanism Geneosis used. Good work.

Portal 2's been updating itself lots recently, so it might have replaced your editoritems.txt file. Try installing BEEMOD again. And the auto installer doesn't detect your steam directory, so you may have to set the install location if steam isn't installed in the default place.

Portal gun at the beginning is automatic (with BEEMOD) if you add an orange auto-portal to your map.
Logic gates are really easy. Add one to your map, right click it, change the button type and look at it in the map to see which is AND, OR, or NOT, depending on which you want. Then press K and connect it to a button/catcher/trigger, press K and connect it to another button/catcher/trigger, then press K and connect it to whatever you want to trigger.

i did install it, its on pc.... but no changes in portal 2 PeTI

Hi, i have BEEmod, but how the hell did you get the portal gun at the beggining, and how do you use the logic gates?

What happens when you try to install it (e.g. are there any error messages?), and what operating system are you using?

i cant install beemod !!!! OMG !!!! ive downloaded both auto install and manual, tried both and everything but no !!! GLaDOS SAID !NO!

Well I don't really care about credits for mechanisms, and it's sometimes fun to see that players get the same ideas at the same time but without any contact :p
Also you the way you used it is not exactly the same so this is some way your own mechanism ;)

Thanks, I did play your map before making this so credit to you for comming up with the idea of the vent/grating combo, I just felt it would work better here with the grating blocking the vent (to stop the ball being destroyed). What would improve it is if the vent would detect the ball and output a signal to the exit door.

That's a really nice use of BEE mod ^^
Don't know if you get the idea of the grid + vent yourself, but I used almost the same mechanism in my demo map for the BEE mod XD
