Handle touch input or mouse click with Unity

unity-handle-touch-or-click.cs

// Example of handling click or touch down in Unity
using System.Collections;
using System.Collections.Generic;
using Unity;

public class CharacterMovement : MonoBehaviour {
  void start() {
    Debug.Log("Start");
  }
  void update() {
    if (Input.touchCount > 0 || Input.GetMouseButtonDown(0)) {
      // Either touch down or Mouse click
      Debug.Log("Explosion");
    }
  }
}

I tested it on android (one click add one shot) and it continuously add shot. As "Input.GetMouseButtonDown(0)" work in android, you can remove "Input.touchCount > 0 ||" from =the condition and now it will work.
