Okay, so in my 2D Minecraft, I am working on world generation. There are 2 arrays (lists) - one for block coordinates, and another for costumes (what block it is). It should put grass blocks all along the bottom and 2 oak blocks, but instead, it has one oak block, and a weird grass thing at the bottom.

To get the world generation, just hit single player.

Thanks for reading!

                                                                            
when green flag clicked                                                              
forever                                                                                         
if <(distance to [nearest train v]) < [10km]> then
go to [nearest train v]
film [train v]
end
end
