Multiplayet switch

[Shred18]

I'm having issues converting this cog to multiplayer. This is the cog that controls the moving catwalks inside the core of level 12 (escape with the map)

Here's the problem: only the host can activate the switches. (which require a key) if a client with a key activates it, and the host doesnt have a key, it will print out on the host computer that he needs a key. I 've made slight modifications, but it still doesn't work.

why not just give the everyone in the party a key if one is picked up?

[Shred18]

becuse the host would still be the only one able to flip the switch.

If I remember right, this has been a common error with JK. When it looks up the bin for the key, it checks the host computer no matter who activated the switch. Try making a client and server cog setup where the client cog (local) gets the bin value (getting the proper player's bin) then calling the server cog (non-local) to open the door. It's an ugly fix, and there's probably an easier way, but I haven't messed with bins much so someone else might be able to find a single cog solution.

[Shred18]

Oh.. well that would make sense, I keep running into this problem with switches.

I would suggest having a look at one of the CTF COGs where they use Keys to open the red and yellow doors. Just suggesting, so solutions, sorry.

I'd say try adding:
flags=0x40
to the cog.

I tested by using flags=0x40 in the above cog.

Everything worked as expected when the host activated the switch (i.e. key worked and catwalk moved).

When the client activated the switch, the key worked, but the catwalk didn't move. (I tested using print statements, so I know the GetInv verb worked properly.)

So, I guess the catwalk is synced differently than the inventory bins.

You have to make new cogs since inventories aren't synched, if I remember right. I made a fully functional & tested MP door keys cogs a while back, dont remember where they are now.. :/

[ZeqMacaw]

I have also tested using the CTF method for keys, and that works fine, too.
