I am using the Survival Shooter tutorial code and i am trying to prototype upgrading damage.
This is the code for PlayerShooting
using UnityEngine;
using UnitySampleAssets.CrossPlatformInput;
namespace CompleteProject
{
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 = new Ray(); // 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.
public Light faceLight; // Duh
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> ();
//faceLight = GetComponentInChildren<Light> ();
}
void Update ()
{
// Add the time since Update was last called to the timer.
timer += Time.deltaTime;
#if !MOBILE_INPUT
// If the Fire1 button is being press and it's time to fire...
if(Input.GetButton ("Fire1") && timer >= timeBetweenBullets && Time.timeScale != 0)
{
// ... shoot the gun.
Shoot ();
}
#else
// If there is input on the shoot direction stick and it's time to fire...
if ((CrossPlatformInputManager.GetAxisRaw("Mouse X") != 0 || CrossPlatformInputManager.GetAxisRaw("Mouse Y") != 0) && timer >= timeBetweenBullets)
{
// ... shoot the gun
Shoot();
}
#endif
// 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;
faceLight.enabled = false;
gunLight.enabled = false;
}
void Shoot ()
{
// Reset the timer.
timer = 0f;
// Play the gun shot audioclip.
gunAudio.Play ();
// Enable the lights.
gunLight.enabled = true;
faceLight.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 this is my ‘DamageUpgrade’ Script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class DamageUpgrade : MonoBehaviour {
public float multiplier = 1.2f;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if (Input.GetKeyDown(KeyCode.U))
UpDamage();
}
void UpDamage()
{
Debug.Log("Damage Up?");
PlayerShooting weaponDamage = GetComponent<PlayerShooting>();
weaponDamage.damagePerShot *= (int)multiplier;
}
}
When I press U the game pauses and gives me the error.
The PlayerShooting Script is on the GunBarrel which is a child to the player.
I Have put the DamageUpgrade Script onto the Player which is Parent to the GunBarrel.
