OnTriggerEnter Doesn't work

Questions & Answers

This is some script from the game I’m making

When the player walks into the object it unlocks the new spell but when I walk the player into it nothing happens. I’m not sure whats wrong because both objects have rigidbodys and colliders with the trigger box ticked.

using UnityEngine;
using System.Collections;

public class Magicmanager : MonoBehaviour
{
    void OnTriggerEnter (Collider other) 
    {
        if(other.gameObject.name == "Book1")
        {
            magic1unlock = true;
        }
    }
}

I had the same problem, and I found an easy solution, have a look at this question.

I ran into the similar problem and i realized that i did turn off Physics Auto Simulation. This will exactly stop all collisions and physics calculations.
