A Simple Trap Cog Request
2005-11-21, 10:13 AM #1
I would like a thrust trap for Multi-player Deathmatch. When one of four pressure plates is trod on, a sound is played (so that everyone in the game can hear it), the forcefield is deactivated, and any player in one of 5 designated sectors is shot upwards at a very high speed.

Because the forcefield is deactivated, they shoot past it, and are killed by the impact of a ceiling above them. Keep in mind that AS LONG AS one or more players are standing on any or all of the four pressure plates, the reactor is shooting upwards, the sound is playing, and the forcefield is deactivated. As soon as the players move off the surface(s) the forcefield is reactivated and everything returns to normal.

This trap needs to work for Multiplayer, so I suppose I need both a client and server cog? Thanks. :)

m4_reactorthrust.cog does most of this. It works with switches instead of pressure plates and doors instead of forcefields. You may want to adapt that one. Also, it's for MP. (It's the Bespin Mining Station thrust trap) It also plays an alarm sound and has a light-effect for warning.

Hope this helps :)

Thanks JoS, I did know of that cog, but I really need the pressure plates, and a forcefield instead of the doors. I don't know enough about cog to modify it myself, so I'm still dependent on some kind cogging soul, I'm afraid... :(

Well, I'm no cogger either, but as far as I know, for pressure-plates, you simply need to change the 'activated' message to 'touched' for the switch surface(s).

I'm sure someone will want to implement your forcefields... it's much less work to adapt that existing cog than to make a new cog from scratch. (I think - but I'm no cogger).

I'm sure someone will want to help you, it shouldn't be too hard for a 'real' cogger. :)

No worries everyone, PhantomCoder has kindly made me the cog. You can see it in action in my hub contest level soon. ;)

Don't forget to post it here when it's done! :D

Thanks for reminding me JoS. Here's the cog. It's free for public use, just remember to credit PhantomCoder for making it:
