This small Block Launcher mod allows you to generate custom maps for Minecraft PE. All you have to do is change the ID of coordinates and blocks, and everything else will make the script.
How does it Work?
The script is embedded in the template of a well known map called "Heavenly hash". To start the generation of the map - you'll need to pick up a stick (ID 280), and tap on the ground. In a moment of time, you will see a huge generated design of the blocks.
How to create your own map?
For this we need to take the time coordinates and block IDs. In the JS file contains all used IDS and an algorithm for their construction. Slightly changing the algorithm, you can get as a result of brand new design.
