Help I don`t know what I`ve done but if I put a switch / floor activator in my game and a light source / door anything to activate / toggle.
When I go to connect switch to light as an example I can drag a line from from the switch to the light source and it will "flash" yellow and blue but it will not latch on at all, does the same with the doors etc. I am on the shooter games tab i.e third one along. Any I have already connected before this problem started are still working fine. Switch is set as a switch in behaviour and I still can`t link it. However I have a wall set as an object ( physics on) with a script attached I can connect this to the light source but not the switch. I put a wall the same as this and connected it to a switch earlier (yesterday) and that works fine. Anybody got a clue.

Run updater (if running GGMax from TGC) or via steam (if running steam version), and recheck your files.

Ran again and for some reason it works. No problems at all now. Thanks for advice 3com
