I am trying to make a ship selector for my shooter game.
I have a ship selector scene and a UI that works, when selecting a ship, it changes a public int in GameSession, which doesnotdestroy. This int does change, and stays persistent on level load.
The player GO has 3 different ships in it, all not enabled, and a script to decide which one to activate.
on Load I am trying to get the Player script to check the public int in GameSession and use that to determine which ship to load.
I can not get Player script to bring back a value other than 0, even if the GameSession inspector says a number.
The only way I can get it to even register is if I put a debug.log on an Item pickup, which is obviously too late. but just to see if it even can read it.
I can’t seem to figure out how to get it to read the value on level load.
I do realize my code is atrocious. I have a lot to learn so far, I just want to make this work for now.
I have no errors related to this.
