modify existing recipe

[grobyc]

I have write some mod, create recipe run game, and play with it.
Now I want modify it and add to technology tree. I do this and problem was appeared.
When I start new game item require technology first and recipe is modify.
When I load old save, item doesn't require technology and recipe use old materials.

Any clue what to do with this?

the title tells me what you need is this:

And with the text I think that what you need to do is to reload the recipes in old saves
To do that you need to use:

game.player.forze.recipes["the recipe name"].reload()

Already done it by creating migration file in mod, good to knew alternative.

And with the text I think that what you need to do is to reload the recipes in old saves
To do that you need to use:

Code: Select all

game.player.force.recipes["the recipe name"].reload()

This is better than

Code: Select all

game.player.force.reloadrecipes();

Because soon(er or later), we will start modifying recipe of players (technology to make some recipes cheaper for example).
This way you would revert all these kind of changes.
