The Flat Fixer code is explained more thoroughly in the video. The first code segment in Flat Fixer, checks the on-chat argument values to verify they are in the correct range. If not, they are set to default values. The variable origin is set to be the initial player world position, but just above were the grass would normally be in a flat world.

Two layers of dirt are restored above the bedrock at Y = 1 and Y = 2. The grass is restored at Y = 3.

Flat Fixer is a companion program to Bang. Using the two programs, Bang can make a mess and Flat Fixer can clean it up again and again and …
