Implementing high scores is a must for almost every game to make players compete with each other or to make players replay levels to improve their result. So let's modify our GameManager class to also manage score for each level.
Inside our GameManager class createLevel method, we already stored default score and time values, so now we only need methods to set and retrieve them.
First, we will create a method to set the score, which would simply take pack and level number and the user score as the parameters, and return true to indicate that the user has beat a high score or false if the user'sscore is lower than the highest score.
So, as done previously for almost each GameManager method, at first we try to load the pack and create the level information if we need. Then we check if the user's high score is higher than the saved one; and if it is, we save the new score and time when it was achieved. Then we return true, else we simply return false.
function GameManager:setScore...
