Problem with Checkpoint counting in Unity 5

Questions & Answers

I’ve made Checkpoint system, where a plane goes through rings and checkpoints are counted. It was done with OnGUI.

Recently I came across one of the Unity tutorials:
http://unity3d.com/learn/tutorials/modules/beginner/live-training-archive/creating-a-jewel-miner-game

It crossed my mind that using UI → Text was better than coding everything manually with OnGUI. I guess it would be more convenient and simpler to modify if I really wanted to do that in the future.

The problem is as follows:
GameManager that is attached to Canvas on the right hand side shows CheckPointCount and TotalCheckpointCount correctly on any particular level. On the other hand on-screen checkpoint count is not changing it’s numbers. It’s always 0/2 with 2 being the amount of Checkpoints on the level. It was done with UI → Text, scripts are attached. I think it’s a problem with code.

Excerpt of code from GameManager.cs:

void Start()
    {
        //Amount of checkpoints = Amount of checkpoints from parent folder
        TotalCheckpointCount = CheckpointParent.transform.childCount;
        CheckpointText.text = ("Checkpoints: " + CheckpointCount + "/" + TotalCheckpointCount);
    }

     //Checkpoint iteration
     public void AddCheckpoint()
    {
        CheckpointCount += 1;
        CheckpointText.text = ("Checkpoints: " + CheckpointCount + "/" + TotalCheckpointCount);
    }

And excerpt of code from Player.cs, when player is colliding with object:

 if (other.transform.tag == "Checkpoint")
        {
            manager.CheckpointCount += 1;
            Destroy(other.gameObject);
        }

I think I should do something with that CheckpointCount in Player.cs, but I’m not exactly sure how to tackle this. Change it with a reference to the AddCheckpoint class from GameManager perhaps? Any ideas would be greatly appreciated.

Hi,

You need to call AddCheckPoint(), that’s the one that will update your text. manager.CheckPointCount += 1 is not needed since you already do it in AddCheckPoint() …

Replace manager.CheckPointCount += 1; by manager.AddCheckPoint(); in your Player.cs script !
