BEWARE! ONLY ONE TANK COULD BE CREATED. HOWEVER, I HAVEN’T TESTED THE EFFECT OF A SECOND ONE BUT I WARN YOU OF THE DANGER FOR YOUR MAPS.

1° Download the folder with the structures and open it.

2° Copy all of the 10 structures in the « structures » folder of a map.

N.B.: if it doesn’t exist, create the folder.

3° In order:

A) Push the « before creating tank » button.

B) Push the « scoreboards creation » button.

C) Push the « create tank » button.

D) Push the « after creating tank » button.

E) Check in one of the repeating command block shown in the picture if the time of the last action is now. If not, click and click again on the « always active » button of the command block. If it still doesn’t work, contact me.

F) Choose coordinates of a block at an height of 200 blocks (with air all around it) and enter it in the 4 repeat command blocks which command the fall of the tank.

Your tank is now ready!

N.B.: you need to do the steps A),C) and D) each time you want to create a new tank.

SUM UP:

Left lever: move backward.
Right lever: move forward.
Left lever: turn left.
Middle lever: shoot.
Right lever: turn right.

If the tank meet an obstacle in front of his tracks, he will climb. If there isn’t any block under the tank, it will fall.
