Hello everyone.
In this post I will show you how to build a generator that can be used in all kinds of maps.
If you have made a "Capture the point" map this can be very helpfull to make every turn to a new game to a new gameplay. :)

All steps image are on the same image.

This will only show 2 outpost, but will also work with more.
Lets start, shall we. :)

List of thing we need:

• Dispensers
  
• All kind of rails
  
• Sticky pistons
  
• Carts
  
• wooden pressure plate
  
• All items of redstone
  
• Cobweb
  
• And a building block.
  

Step 1:
Build just like the image. It is important that the cobweb is on the block infront of the dispenser. The block thats been shot out will then fall and trigger the wooden pressure plate.

Step 2:
Build in the cobweb so it have a block to everyside, execpt for the block under (top dosent matter). Build a redstone loop as the image.

Step 3:
Follow the image and just copy it. In this point you have add a sticky piston that will close the way forever when this way has been choosed.

Step 4:
Add 3 more redstone Torches just the way the image shown.

Step 5:
From the redstone torch you just add you will build a way that will splitt up and placing on the top of the other pistons. Then add more redstone on the blocks. Watch image.

Step 6:
At this point all ways will be closed forever, because the redstone torch is active. But here is the solution. From the last step you must add up more blocks and 2 more redstone torches. Watch the image and copy.

Step 7:
Build a way that goes up with blocks. On the top you will add a power rail with a cart on it. The rails must be facing down. Watch the image and copy.

Step 8:
From the block that the rail is on, add 12 cobweb (12 is not needed. It depens what you use it to) infront of the block the rail is on. The cart goes throu one web in 30 sec. once on ground you will have a active power rail that are also facing down. Watch image and copy.

Step 9:
Make a rail back to the redstone torch with one block space between. Add a detector rail on the end of it and put a repeter next to it. The repeter must have his output into the block that the redstone torch is on. With that the torch will be off again and all pistons will open.

Step 10:
The machine is done. Fill all dispensers with a item that doesnt fire it out. Arrows does not work, but building block works fine. :)

I hope this will help your mapmaking, and remember that you can add even more ways.
If any have a question about it, just ask. :)

Take care.
