Factorio Forums

When i played Factorio again today after a long while smth made me laugh a bit.
Why is it that i can catch a Fish in a deeply Poisonous Green Lake, surrounded by heavy Machinery, eat that, and then gain health from it?

I mean this is just a small irrelevant Detail but what if they would only Spawn in Blue Fresh Water?

Could be a nice little Detail i think

Fish already only spawn in clean water, since they are only created once on map start.

Exactly, fish don't spawn either way. One could argue that pollution should kill fish, similar to how it kills trees, but I think such a change would only make sense if fish become reproducing (which would be logical, but not do much for gameplay in my opinion).

They only Spawn once at Game Start? But new created Lakes Spawn them too i guess?

If that is true then the Idea is obsolete ofc. Maybe they could mutate instead?

The game doesn't create new lakes later - it's all in existence since game start from the player's point of view. You might see the engine create new chunks on the fly when you explore them, but actually it is made as if all exists since game start. Since it's all dependent and based on the map seed, actual instantiation as visible objects in the game can be postponed until the player actually looks at them.

All games with the same map seed are created with the same world. If you look at a water tile 100 hours into a game 100 chunks away from the start area and locate all the fish in it, it wouldn't look any different as if you just take the map seed, create a new game, and locate the same tile just after creating the game. You will find the same fish in it.
