Having trouble loading a canvas once all collectibles have been collected

Question

UPDATED CODE

In my 3d Unity game I am trying to add in a canvas once all the collectibles are collected that says "Level completed... loading next level" and then loads the next level but once all the collectibles are collected, the game still plays. The script is successfully disabling the canvas but its not re-enabling it once the 5 collectibles are collected and the score reaches 5. Please help. Heres a screenshot of my script.

Collectible Script

Answer 1

The problem is because you are destroying the object with the script before running the code that enables the canvas, because your script is attached to your collectable. Try disabling the mesh renderer and collider of your pickup, then destroying it after the code has run.

private MeshRenderer meshRenderer; // the mesh renderer attached to  the player
private Collider collider; // pickup's collider

private void Start ()
{
    meshRenderer = GetComponent<MeshRenderer>(); // get the mesh renderer component from the pickup (put this in the start function)
    collider = GetComponent<Collider>(); // get the collider attached to the pickup 
}

In your OnTriggerEnter function instead of using Destroy (gameObject), use meshRenderer.enabled = false and collideer.enabled = false. Then at the end of your OnTriggerEnter function, you can use Destroy (gameObject).

Also you don't need a separate canvas for every UI element. You can just have 1 canvas that contains all the different menus/elements and enable each of those.
