Hi, I have a problem dealing with time in this line of code:
Time.timeSinceLevelLoad % levelUpBySeconds == 0f;
It works perfectly if I’m in the scene with that script in empty gameObject called “GameManager” in “Level_Start” scene as my starting scene, but when it came from other scene (“Start_Scene”) and load it or load it again ( Application.LoadLevel("Level_Start") / using UnityEngine.SceneManagement; SceneManager.LoadScene("Level_Start") ) – it does not work anymore. Why is this happening?
Is Time.time or Time.timeSinceLevelLoad loses its precision in calculations when Application.LoadLevel() is done? or is the problem with modulus ( % )?
My “Level_Start” scene:
You see, when I play this scene with my editor, this works properly; let’s say, I set my public preference “levelUpBySeconds” to 10, it means every 10 secs will update my “LevelValue” in hierarchy added by 1, and also instantiate 1 “EnemySpawn” prefab every level rises by 1: (working properly)
My “Start_Scene” scene: if I start here or go here…
…and go to “Level_Start” scene (again) by Application.LoadLevel(); now the “LevelValue” stays at 1 forever: (not working)
Please just look for this line below:
if (Time.timeSinceLevelLoad % levelUpBySeconds == 0f && Time.timeSinceLevelLoad > 0f) in line 38 (and also 54 which have no problem unlike line 38) of GameController.cs.
Note: I have tried Time.time - timeElapse % levelUpBySeconds == 0f where timeElapse is a variable initiate from start with Time.time, or Mathf.Repeat(Time.timeSinceLevelLoad, levelUpBySeconds) == 0 still the same result…
