I made a vanilla trading system at my alt at /visit aerumnae on net, and /visit K41YU on org. There should not be any loopholes or flaws, but if there is, let me know. I made this for people to trade for things they don't have to use to make a chest shop, as you need to hit the sign with the other item you're asking for. Also people have been getting scammed lately as well. What do you think of it? Here's how it works: Step 1: Both players get into separate rooms then they close it off with the lever "close entrance". Step 2: Make sure the green lever is on down position on both sides. You can see here that the lever is up on the other side and it should not be up. Make sure the other player puts down their lever first before inputting items to trade off. Step 3: Climb the ladder and look at what the other player is offering you. Step 4: Input items you are trading off in the hole. Here, I am trading a gold block. It might be a little hard to put items into the hole, but I want to make sure you can't pick it back up unless you press the cancel button. It used to be a slab instead of a trapdoor, but the trapdoor now makes it way easier. Step 5: Cancelling. You can press the red button to cancel the trade if any of you don't like the offer. The gold block and fish will go back to the players. You can pick up canceled items over at this water stream. Sometimes canceled items will clip through the water stream’s wall and immediately into your inventory. Don’t worry, it does not clip into the other room, only your room. Step 6: Accepting. If you both agree with the trade, you both have to flick the green lever up. Then, a piston retracts and you can pick up your items here at the other water stream. You can redo/reset a trade by canceling and putting the green levers at down position. I also added a spectator window on both sides, so you can have friends witness/record your trades. This is step 4's glass window. Clear lag may be a problem with this system so make sure to cancel trades and wait for it to pass. Also, it's difficult to tell the number of items when they stack on the floor, so you'll need to have evidence of conversations, what you and the other player will be going to trade. Have a video recording going or take full uncropped screenshots of the Minecraft window showing the chat. Save the evidence and thennn you can trade. That way if there are any complications, you have evidence.
It's technically my gf's account so I don't think I'll change it. But perhaps she could pick out a simpler username to type in.
I can make this on the other servers as well. Except I’m broke on econ and would need 2 sticky and 2 regular pistons. But I’ll check if I have enough materials later. They would be on my main acc at /visit K41YU.
I just need the pistons. I can use any blocks but I just happened to want to use purpur and make it look nice.
Update: Finished another on econ at /visit K41YU. Did not make one for classic because I forgot there's no such thing as /settings.
Update: A player noted step 3 (throwing items into the hole) was difficult so I've replaced the slabs with thin trapdoors. You should not be able to pick up your thrown items without pressing cancel to prevent ghosting on trades. I also added more spectating windows.
Update: Made the design more compact and better, and moved it to an alt named /visit WarpTrade. Or should I have named it something else? I'll change it in a month if the name is too confusing with /warp trade. Also added some fun noises when you accept or cancel trades. \o>
Update: Major bug fix. I found out if you press cancel while someone is standing in the pickup area piston, it clips through the wall and goes to the other person. I added a block so that players can't stand in that area until the trade is finalized and accepted.
It was already suggested about a trading warp here: Skyblock - Improved /warp trade. | Skyblock Forums This is to take place if it's not implemented.
Love it! Clearlag would be the only thing that scares me, maybe huge signs to warn them about clearlag.
Update: I've added furnaces. You can use this for items you wish to pass over without going through the whole throwing items and lever stuff. Pretty much the same as going into a closed off room and passing items.
