Hi.
I modified my mod to create a new technology.
But now one of my custom technologies needs to require this one first.
Will it work directly in old saves or do I have to reset the tech somehow so that players will have to research the previous tech first before having access to this one ?
Thanks

game.player.force.technologies["name"].reset()
Where name is the name of your tech.
Add this to the migration script.

I don't know wht a migration file is

Edit : found out how to make a migration file.
Now the problem is, i want the previous tech to be already researched if the other one is, how do I do this ?
the field "researched" is read only.
enable() will only allow players to research it ..

In migration script first check to see if the other techonology is already researched by the player.
If it is you do nothing if it is not then you call "game.player.force.technologies["name"].reset()"

You don't get it, so i'll explain :
Before I had technology A.
Now I added technology B that's REQUIRED to even be able to research A.
I want to make it so everyone with already A don't have to research B. using reset() won't enable B is they already have A. That's what I want to do.

to set whether it is enabled or not you can use game.player.force.technologies["name"].setresearched(true) or false if you needed to do that later.

That's what I wanted ! Thanks
