Uh, if you are asking if having an abundance of logic_relay's is a bad thing, than no. It may be possible to combine them, but without either seeing your map and/or having the VMF, it's hard to be certain. 9 of them is not bad at all.
You need to have something else send the Ignite (or maybe Activate) I/O to it, like a trigger or a logic_relay.
I will try the trigger right away. Thanks.
logic_relays allows mappers to script their events in a basic "object-oriented" style. Each logic_relay should handle a specific task that could be repeated independently. At no point a single logic_relay should handle a very long and complicated serie of outputs. It's way more difficult to create and maintain (because the output view of entities is not really appropriated for a large quantity of outputs) and it's also way more difficult to debug.
You still have some time before you could have a problem with input/output overflow. One day, I made an "amusement park" for Half-Life 2: Deathmatch, there was attractions moving everywhere, things spinning, things making smoke, musics and sounds playing, lights and sprites were flickering all the way out, and THERE I had a problem with input/output overflow. But there was like 40 or 50 outputs sent per second. So... don't be so anxious. The more the better.
Even though some calculation power is put in the I/O system, that's nothing compared to the ammount of power put in the rendering system. Of course, that doesn't mean you have to overdo it. But personally, I like logic systems more than enviroments. That's why I enjoy mapping for Portal so much.
Thanks a lot everyone. After finding out that more logic_relays are beneficial I was able to fix some of the coding and now have the map working way better than before. Including such the jobs of the User1-4 have been given to 4 new logic_relays. Thanks for the assistance.
The User1-4 I/Os are in my opinion generally worthless. I can not think of a single instance where they would be useful to use.
Hmm, maybe I should make something compareable for the "Lights out on a 3x3 grid"-puzzle... once I got the map finished. Don't want anyone to steal it prematurely, of course.
