The traps are finished, I just went with pistons that crush the player set off by pressure plates underneath. Had limited time online this arvo so tried to knock it up quick. Sorry Duck, didn't get to yours but it's on my to do list next time i'm online.
Have tested all the traps and they are all lethal. Also it is quite random as to where you fall, and once you get going with the water pushing you it's nearly impossible to stop.
Just gotta set up chests and beds for players, finish the surface with snow and it's playable!
I also wanted to ask any players that have snow, or free time to grab and save it for me if they can, snow is probably the best surface to play on as it breaks easy even without tools and is easy to see, but there is none near where the arena is made so if you pick some up on your travels or clear some out in your building please save it and I'll make a chest that can be filled and used to reset the surface after matches and place it in spawn near the bullettin board.
Will have to have a big all in game when it's done wich will be soon, offer is still out there for someone to design/do the building to house it in. If no takers, I'll just do some basic defense to keep unfriendly mobs out.
