Factorio Forums

Info:
This mod was made with the idea to test how big the Factorio map can actually get on your pc.
When enabled, the player with automatically move in a given direction, destroying any (possible movement blocking) entities on its path.

Best ran with:
- new singleplayer map with:
- water only in starting area (try again if you get stuck)
- enemies never attack first

Enable "show_detailed_info" in the debug settings (F4, tab "always") to see where you actually are in the map.
Notes:
- made for http://steamcommunity.com/app/427520/di ... 863402518/
- if you loaded this on a map you actually play, and saved over your main slot (by accident or not), you might want to set the game speed back to 1 after unloading the mod:
/c game.speed = 1

Config: (unzip & edit control.lua to change)
- walking_direction, default = west (doesnt really matter for end result)
- auto_destroy_area_radius, default = 2 (area of 4x4 around player, works with biter nests and big rocks)
- auto_destroy_per_ticks, default = 10 (this seems to work fine)
- game_speed, default = 2. Increase if your pc can handle faster

Seems like after ~8k chunks, the graphics flip out .

Graphics flip out whenever you're reaching new chuncks too fast. There probably should be pauses to allow map generator to catch up with demand.

Yeah i ran it with game speed = 20. That might have been a bit too much.

Edit:
Stopped the game right before i got problems, then disabled the mod.
Now i walk manually...i can go in all directions just fine, it will generate new terrain and everything just works.

But if i keep going west after ~8190 chunks...the graphics just give up.
Very reproducible

Not gonna actually walk to find out, but the largest map size is gonna be based off the type of the variable being used for coordinates. If it was a 64bit integer that would mean 9,223,372,036,854,775,808 squares from spawn point. If it was using a double precision float then while you could technically track a much MUCH bigger value you only get 15 digits that are precise. Meaning somewhere between 1x10^15 and 1x10^16 tiles from origin before the map starts being generated strangely and physics/movement act up weird.

IE: your computer will run out of ram before you could find out how big a map is spawnable

Sure theoretically.

But i made this just for fun, to see how far you can practically go.

Understood. I just posted the numbers for people who want a concrete answer and are too lazy to actually try it
