Hey there,
I am learning Unity with this tutorial: Survival Shooter Q&A - Learn Content - Unity Discussions
When I test the shooting, it keeps going through the Zombunny without harming or killing it. The LineRenderer goes through the Zombunny and does not stop.
When browsing around, it seems that people encountering this issue have solved it by setting the Zombunny’s layer to “Shootable” - which is already the case for me 
Anyone could help me here? Thanks!
Here’s my PlayerShooting script:
using UnityEngine;
public class PlayerShooting : MonoBehaviour
{
public int damagePerShot = 20; // The damage inflicted by each bullet.
public float timeBetweenBullets = 0.15f; // The time between each shot.
public float range = 100f; // The distance the gun can fire.
float timer; // A timer to determine when to fire.
Ray shootRay; // A ray from the gun end forwards.
RaycastHit shootHit; // A raycast hit to get information about what was hit.
int shootableMask; // A layer mask so the raycast only hits things on the shootable layer.
ParticleSystem gunParticles; // Reference to the particle system.
LineRenderer gunLine; // Reference to the line renderer.
AudioSource gunAudio; // Reference to the audio source.
Light gunLight; // Reference to the light component.
float effectsDisplayTime = 0.2f; // The proportion of the timeBetweenBullets that the effects will display for.
void Awake ()
{
// Create a layer mask for the Shootable layer.
shootableMask = LayerMask.GetMask ("Shootable");
// Set up the references.
gunParticles = GetComponent<ParticleSystem> ();
gunLine = GetComponent <LineRenderer> ();
gunAudio = GetComponent<AudioSource> ();
gunLight = GetComponent<Light> ();
}
void Update ()
{
// Add the time since Update was last called to the timer.
timer += Time.deltaTime;
// If the Fire1 button is being press and it's time to fire...
if(Input.GetButton ("Fire1") && timer >= timeBetweenBullets)
{
// ... shoot the gun.
Shoot ();
}
// If the timer has exceeded the proportion of timeBetweenBullets that the effects should be displayed for...
if(timer >= timeBetweenBullets * effectsDisplayTime)
{
// ... disable the effects.
DisableEffects ();
}
}
public void DisableEffects ()
{
// Disable the line renderer and the light.
gunLine.enabled = false;
gunLight.enabled = false;
}
void Shoot ()
{
// Reset the timer.
timer = 0f;
// Play the gun shot audioclip.
gunAudio.Play ();
// Enable the light.
gunLight.enabled = true;
// Stop the particles from playing if they were, then start the particles.
gunParticles.Stop ();
gunParticles.Play ();
// Enable the line renderer and set it's first position to be the end of the gun.
gunLine.enabled = true;
gunLine.SetPosition (0, transform.position);
// Set the shootRay so that it starts at the end of the gun and points forward from the barrel.
shootRay.origin = transform.position;
shootRay.direction = transform.forward;
// Perform the raycast against gameobjects on the shootable layer and if it hits something...
if(Physics.Raycast (shootRay, out shootHit, range, shootableMask))
{
// Try and find an EnemyHealth script on the gameobject hit.
EnemyHealth enemyHealth = shootHit.collider.GetComponent <EnemyHealth> ();
// If the EnemyHealth component exist...
if(enemyHealth != null)
{
// ... the enemy should take damage.
enemyHealth.TakeDamage (damagePerShot, shootHit.point);
}
// Set the second position of the line renderer to the point the raycast hit.
gunLine.SetPosition (1, shootHit.point);
}
// If the raycast didn't hit anything on the shootable layer...
else
{
// ... set the second position of the line renderer to the fullest extent of the gun's range.
gunLine.SetPosition (1, shootRay.origin + shootRay.direction * range);
}
}
}
And my EnemyHealth script:
using UnityEngine;
public class EnemyHealth : MonoBehaviour
{
public int startingHealth = 100;
public int currentHealth;
public float sinkSpeed = 2.5f;
public int scoreValue = 10;
public AudioClip deathClip;
Animator anim;
AudioSource enemyAudio;
ParticleSystem hitParticles;
CapsuleCollider capsuleCollider;
bool isDead;
bool isSinking;
void Awake ()
{
anim = GetComponent <Animator> ();
enemyAudio = GetComponent <AudioSource> ();
hitParticles = GetComponentInChildren <ParticleSystem> ();
capsuleCollider = GetComponent <CapsuleCollider> ();
currentHealth = startingHealth;
}
void Update ()
{
if(isSinking)
{
transform.Translate (-Vector3.up * sinkSpeed * Time.deltaTime);
}
}
public void TakeDamage (int amount, Vector3 hitPoint)
{
if(isDead)
return;
enemyAudio.Play ();
currentHealth -= amount;
hitParticles.transform.position = hitPoint;
hitParticles.Play();
if(currentHealth <= 0)
{
Death ();
}
}
void Death ()
{
isDead = true;
capsuleCollider.isTrigger = true;
anim.SetTrigger ("Dead");
enemyAudio.clip = deathClip;
enemyAudio.Play ();
}
public void StartSinking ()
{
GetComponent <NavMeshAgent> ().enabled = false;
GetComponent <Rigidbody> ().isKinematic = true;
isSinking = true;
//ScoreManager.score += scoreValue;
Destroy (gameObject, 2f);
}
}
Thanks a lot! Adriana
