Basic Bullet Hole

The following snippet shows how to implement a simple bullet hole creation component with EasyDecal.
 

using UnityEngine;
using ch.sycoforge.Decal;
 
/// <summary>
/// Demo class for runtime decal placement.
/// </summary>
public class DynamicDemo : MonoBehaviour 
{
 
    public EasyDecal DecalPrefab_A;
 
     
    // Update is called once per frame
    void Update () 
    {
        if (Input.GetMouseButtonUp(0))
        {
            // Shoot a ray thru the camera starting at the mouse's current screen space position
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            RaycastHit hit;
 
            // Check if ray hit something
            if (Physics.Raycast(ray, out hit, 200))
            {
                // Draw a line along the projection axis for visalizing the projection process.
                Debug.DrawLine(ray.origin, hit.point, Color.red);
 
                // Instantiate the decal prefab according the hit normal
                EasyDecal.ProjectAt(DecalPrefab_A.gameObject, hit.collider.gameObject, hit.point, hit.normal);
            }
        }
    }
}
