OnTriggerEnter() is occasionally not occurred

I am making some kind of casual sport game with some rhythm-tap contents.

I tried to make a system of touching to decide what score you get for that trial.

A target pad comes down from top, and there is a “node”. If you touch right in time(when the node is in the target area), it will gives you certain amount of score.

the dark green-white area is target, and the white line under red person is node.

I have named dark-green area “pass”, light green area “good”, and white area “perfect”.

And I have created a code

using UnityEngine;
using System.Collections;

public class NodeCtrl : MonoBehaviour {

	public GameMgr gameMgr;
	public int score = 0;

	void Awake(){
		gameMgr = GameObject.Find ("GameMgr").GetComponent <GameMgr>();
	}

	void OnTriggerEnter(Collider coll){
		if (coll.CompareTag ("PERFECT")) {
			Debug.Log("perfect");
			score += 1;
		}
		if (coll.CompareTag ("GOOD")) {
			Debug.Log("good");
			score += 1;
		}
		if (coll.CompareTag ("PASS")) {
			Debug.Log("pass");
			score += 1;
		}
		coll.enabled = false;
	}

	public void SendBackScore (){
		Debug.Log (score);
		//GameObject.Find ("GameMgr").GetComponent<GameMgr>().Call(score);
		gameMgr.Call (score);
		score = 0;
	}
}

However the console log occasionally says that I have got “miss”(which is 0 of score) when appropriately matching the node into target area. It happens about once in 5~15 trials randomly. By checking with Debug.Log(), it seems like to be that the OnTriggerEnter() part of my code does not work properly.

What can I do for solving this?

I don’t really understand when/how you get the “miss”, but try to set “Collision Detection” to “Continuous” or “Continuous Dynamic” on the rigidbody.
It often helps to prevent problems with collisions/collider.
