Bug with ungenerated chunks

[Senoro]

Like already mentioned on the forum, there is a bug wth ungenerated chunks and the mod trying to access them. I´ve redone some of the code and now the bots head back towards the middle if they sense an ungenerated chunk and request chunkgeneration if they get to close to them (security code in case of a missing chunk on their way back) here´s the code I added after the charting code

chunkposition = {x=math.floor(position.x/32+0.5), y=math.floor(position.y/32+0.5)}
xp=-4
while xp < 5 do
    yp=-4
    while yp < 5 do
        if not game.surfaces[1].is_chunk_generated(chunkposition) then
            if yp < 2 and yp > -2 and xp < 2 and xp > -2 then
                game.surfaces[1].request_to_generate_chunks(position, 128)
                game.players[1].print("Generated new Chunks at " .. position.x .. ", " .. position.y)
            end
            local goal = {x=0,y=0}
            if position.x > 0 then goal.x = position.x -150 else goal.x = position.x + 150 end
            if position.y > 0 then goal.y = position.y -150 else goal.y = position.y + 150 end
            squad.unitGroup.set_command({type=defines.command.go_to_location, destination=goal, distraction=defines.distraction.none})
            xp=5
            yp=5
        end
        yp=yp+1
    end
    xp=xp+1
end

Good luck with further development

Hi, thanks for this! I will consider integrating it to the mod. The situation where they try to path into an ungenerated chunk is super rare, and the devs have made it impossible for a "move" command to be successfully issued into an ungenerated chunk too. I suppose it could happen if they are walking around at the edge of the generated map while fighting biters, but it might be different code to handle that.

This part "if not game.surfaces[1].is_chunk_generated(chunkposition)" is the most important, i might use this in other areas of the code if I don't end up using this entire snippet

I´m glad I could help. But be careful if you´re only using them generation code as it might lead to a very big save in a matter of hours.
