I am making an achievement system.I have to 2 scene in my game.The first scene is my Main Menu and the other scene is my game scene. I have designed and coded the achievement system in the main menu scene and added a EarnCanvas to my game scene. EarnCanvas will display the achievement that the player has unlocked.
Code i have is only allowing me to link the achievements to a EarnCanvas on the Main Menu scene.i need help to modifier the code or link the two scene so that i can instantiate the unlocked achievement prefab in the EarnCanvas in the game Scene. At the moment no prefab is instantiated or displayed in the EarnCanvas when the player has unlocked an achievement.
