Cog Multiplayer Problem
2004-08-18, 10:28 AM #1
The original coding was by Edward, but I made a few modifications to it, and now the cog doesn't work the way I want it to. Basically, when a player steps on a switch, nothing happens, but when the other player steps on the other switch, the stairs should be moving to their 2nd frame. The problem is that the stairs go to their 2nd frame when one player steps on a switch. Why does it do this, and how do I fix it?

Problem lies in the "entered" message -- after "if(status == 3)", the MoveToFrame()'s should be enclosed by braces, because currently, only the first one is (if statement's "imaginary" braces) while the rest will always be executed.
But I think I may have given him (or someone) that code some time ago [edit]well, I'm half right by this statement [http://forums.massassi.net/html/wink.gif] [/edit] -- it was the same concept except it was for a door opened by the 2 switches, and the "status" use is used like I remember using it.

Heh, whether it is or not, I made some changes to the code you presented, because that one has a bug that will close the steps if someone steps off the switch (regardless of if there is still someone on it). This updated version will keep track of how many people are on each switch and when the LAST person steps off, THEN it will close. It also keeps track of the status slightly differently (boolean is way easier and can more easily be modified [http://forums.massassi.net/html/smile.gif] )

[edit](okay, did some searching -- it's Edward's but I modified it a bit here [http://forums.massassi.net/html/smile.gif], which is your thread)
