Script connection to other Script - c#

I have a script in diferents objects to my boss. I program the script when the healt of boss is 10 or lower the speed to the other script is set to 4. I attach the first script to other script but dosen't work, the speed isn't change when the healt is low and i have no idea whats is the problem.
public int health = 12;
private gameMaster gm;
private UnityEngine.Object explosionRef;
public GameObject Hiedra;
public bool isHurt = false;
private HiedraScript ChangeVelocity;
void Start()
{
gm = GameObject.FindGameObjectWithTag("GameMaster").GetComponent<gameMaster>();
explosionRef = Resources.Load("Explosion");
ChangeVelocity = gameObject.GetComponent<HiedraScript>();
}
void Update()
{
}
void OnTriggerEnter2D(Collider2D collision)
{
if (collision.CompareTag("Bullet"))
{
Destroy(collision.gameObject);
health--;
Hiedra.GetComponent<Animation>().Play("Player_RedFlash");
if (health <= 10)
MovesFaster();
isHurt = true;
if (health <= 0)
KillSelf();
}
if (health <= 0)
{
gm.points += 20;
}
}
private void MovesFaster()
{
ChangeVelocity.moveSpeed = 4f;
}
and the other value in diferent script:
public float moveSpeed = 1f;

Did you try to Debug.Log()?
If unity logging something so you have idea if it really calls MovesFaster() Function.
If so, you can mark moveSpeed variable as static and you can access it. I think this variable in a class inherited from monobehaviour. If you want to all public variable even that not static you can use singleton pattern. Singleton pattern is so useful in many cases.

Updating Enemy Health bar in unity 2d

Why is this connecting all the health bars of my enemies together, even though their actual health is decreasing at its specified rate?
public class FillHealth : MonoBehaviour
{
Image HealthBar;
private NormalMonster normalMonster;
// Start is called before the first frame update
void Start()
{
HealthBar = GetComponent<Image>();
normalMonster = GameObject.FindGameObjectWithTag("Normal Monster").GetComponent<NormalMonster>();
}
// Update is called once per frame
void Update()
{
UpdateHealthLeft();
}
public void UpdateHealthLeft()
{
if (normalMonster.healthLeft > 0)
{
HealthBar.fillAmount = normalMonster.healthLeft / normalMonster.setHealth;
}
}
}
This is the script that is being referenced in FillHealth. As far as I understand it, since the variable isn't static, then the values should not be shared. It should find fill the health bar for each individual enemy.
public class NormalMonster : MonoBehaviour
{
private float _normalSpeed = 2f;
private float _BaseHealth = 20f;
private float _HealthModifier;
public float setHealth;
public float healthLeft;
// Start is called before the first frame update
void Start()
{
UpdateHealth();
}
// Update is called once per frame
void Update()
{
NormMonMov();
}
public void OnTriggerEnter2D(Collider2D other)
{
if (other.tag == "Arrows")
{
healthLeft -= Arrows.Damage;
Destroy(other.gameObject);
if (healthLeft <= 0f)
{
Destroy(this.gameObject);
EarnedGold.earnedGold += 7;
Spawn_Manager.enemyCount--;
}
}
}
public void UpdateHealth()
{
if (StageMode.StageLvl > 5)
{
_HealthModifier = (StageMode.StageLvl * 0.01f) * _BaseHealth;
setHealth = Mathf.Round(_BaseHealth + _HealthModifier);
}
else
{
setHealth = _BaseHealth;
}
healthLeft = setHealth;
}
public void NormMonMov()
{
transform.Translate(Vector3.left * _normalSpeed * Time.deltaTime);
transform.position = new Vector3(Mathf.Clamp(transform.position.x, -7.0f, 10), transform.position.y, 0);
}
}
Any help would be greatly appreciated for this guy who just start playing with unity this weekend.
I believe the issue is with normalMonster = GameObject.FindGameObjectWithTag("Normal Monster").GetComponent<NormalMonster>();
If you have two Monsters
Both have two scripts attached, FillHealth and NormalMonster
Both the "FillHealth" scripts look for the FIRST gameobject in the scene that has a script with tag NormalMonster so both monsters are pointing to the exact same NormalMonster script (the first in the list)
Change "GameObject" capital G to "gameObject" lower case g
Still not the best way to code this, but that may work I think
Instead of getting the image, get the rect transform, like this
public RectTransform healthBar;
and change the length with:
healthBar.sizeDelta = new Vector2(normalMonster.healthLeft,healthBar.sizeDelta.y);

Unity-Breakout Game with a Healthbar

I'm making a breakout game, and I wanted to add a healthbar that decreases when the ball touches a certain object with the tag "hazard". I have a Game Manager Script, and A Pickup interact script, but with the way I set it up, I'm kind of confused with how to trigger takedamage from my GM script to my pickup script, considering I put my playerhealth elements into my GM script, so I can attach it to empty gameobject call Game Manager, since the actual player isnt in the hierarchy, but instantiated during runtime. I'm hoping I don't have to redo the whole thing just for this purpose. If someone could help me figure this out, I'd appreciate it.
Here's my GM script:
public class GM : MonoBehaviour
{
public int lives = 3;
public int bricks = 20;
public float resetDelay = 1f;
public Text livesText;
public GameObject gameOver;
private GameObject clonePaddle;
public GameObject youWon;
public GameObject bricksPrefab;
public GameObject paddle;
public GameObject deathParticles;
public static GM instance = null;
public int startingHealth = 100;
public int currentHealth;
public Slider healthSlider;
bool isDead;
bool damaged;
void Awake()
{
currentHealth = startingHealth;
TakeDamage(10);
if (instance == null)
instance = this;
else if (instance != this)
Destroy(gameObject);
Setup();
}
public void TakeDamage(int amount)
{
damaged = true;
currentHealth -= amount;
healthSlider.value = currentHealth;
if (currentHealth <= 0)
{
LoseLife();
}
}
public void Setup()
{
clonePaddle = Instantiate(paddle, transform.position, Quaternion.identity) as GameObject;
Instantiate(bricksPrefab, transform.position, Quaternion.identity);
}
void CheckGameOver()
{
if (bricks < 1)
{
youWon.SetActive(true);
Time.timeScale = .25f;
Invoke("Reset", resetDelay);
}
if (lives < 1)
{
gameOver.SetActive(true);
Time.timeScale = .25f;
Invoke("Reset", resetDelay);
}
}
void Reset()
{
Time.timeScale = 1f;
Application.LoadLevel(Application.loadedLevel);
}
public void LoseLife()
{
lives--;
livesText.text = "Lives: " + lives;
Instantiate(deathParticles, clonePaddle.transform.position, Quaternion.identity);
Destroy(clonePaddle);
Invoke("SetupPaddle", resetDelay);
CheckGameOver();
}
void SetupPaddle()
{
clonePaddle = Instantiate(paddle, transform.position, Quaternion.identity) as GameObject;
}
public void DestroyBrick()
{
bricks--;
CheckGameOver();
}
}
And here's my Pickup Script:
public class Pickups : MonoBehaviour {
public float PaddleSpeedValue = 0.5f;
private bool isActive = false;
public float thrust=20f;
public Rigidbody rb;
GameObject player;
private void OnTriggerEnter(Collider other)
{
if (other.tag == "Hazard")
{
isActive = true;
Destroy(other.gameObject);
}
}
}
The Pickups class should not have or store a reference to the player at all (although it is not clear from your question if this is a script attached to the player or attached to something else). Your Game Manager class should. Afterall, it is the class that is responsible for managing the game which includes the player. From there, you can use GetComponent<?>() to access any scripts attached to the player GameObject.
Then as the GM contains a public static reference to itself, any other class can get a reference to the player by doing GM.instance.player as needed, even if the player is created and destroyed several times (as the GM should always have a reference to the current one!)
Presumably the clonePaddle field is the player('s GameObject), all you have to do is make it public.

Unity How to remove gameobject if they are on same line?

I am making a game like 2 cars. And I have written code to create a instantiater. It is a car game and there are 4 lanes. Let me show you a picture of my game and yeah this is solely for practise.
Player should avoid square objects and eat circle objects but sometimes 2 square objects get spawned in a same lane making impossible for player to win. I have written this script to control that but I failed. Please help me. At least have a check to my DetectSameLaneFunction(). And tell me what I am doing wrong.

FindObjectOfType returning null

The issue I am having is with a dropped item i pick up adding ammo to a gun.
Built a Gun class with all the methods and variables.
Built a Rifle class derived from the Gun class
The Rifle works perfect No Issues
I now am adding a "PickUp" system where x amount of enemies drop a pickup.
This is the script on the item to pick up
public class AddARAmmo : MonoBehaviour
{
private Rifle rifle;
private void Awake()
{
rifle = FindObjectOfType<Rifle>();
}
private void OnTriggerEnter(Collider other)
{
if (other.tag == string.Format("Player"))
{
rifle.AddAmmo(30);
Destroy(gameObject);
}
}
}
The rifle and gun scripts are kind of long but here is the relevant stuff from the Gun base class is public abstract class ......
public int bulletsInStock;
public void AddAmmo(int ammoToAdd)
{
bulletsInStock += ammoToAdd;
UpdateAmmo();// updates on screen Ammo
}
......
Then in the Rifle Class
public override void Modifiers() // This is where the guns starts are stored
{
bulletSpeed = 2777f;
bulletsInStock = 200;
bulletsInMag = 30;
bulletPoolSize = 40;
desiredRPS = 15;
muzzleFlashPoolSize = 10;
}
I am getting an Object Reference Not Set To An Instance
The Rifle script is on the rifle in the game hierarchy so it should find it.
Does anyone see anything wrong?

There are three reasons why FindObjectOfType may return null:
Let's say the script name to find is Rifle:
And FindObjectOfType<Rifle>() is returning null.
1.The GameObject the Rifle script is attached to is in-active. You must make sure that the GameObject is active.
2.The Rifle is not attached to any GameObject at-all. Make sure that the Rifle script is attached to a GameObject..
It doesn't matter if the script is enabled or disabled, it should find it as long as the GameObject it is attached to is active. See #1.
3.When loading new scene:
When you trigger scene loading with functions such as SceneManager.LoadScene
and Application.LoadLevel, FindObjectOfType will not be able to find anything until the scene loading it done.
See here for how to check when scene has finished loading.
If you still have problems which you shouldn't, simply find the GameObject then get the Rifle component from it. Assuming that the name of the GameObject is "Rifle" too.
GameObject.Find("Rifle").GetComponent<Rifle>();
I figured out how to fix this for anyone having a similar issue.
The issue was when the enemy dropped the item, the Awake() method ran. When it ran the gun was inactive in the scene so FindObjectOfType did not find the reference script because as mentioned above, It has to be active in the scene to be found.
So what I did was create a Holder script i called EnemyDrops and this script calls the findobjectoftypes for the guns. That way the call is done on the initial game start .
I then changed the pickup to find the EnemyDrops script(which is on en empty game object) and send the call to it.
EnemyDrops Script
private Handgun handgun;
private void Awake()
{
handgun = FindObjectOfType<Handgun>();
}
public void AddHandgunAmmo(int x)
{
handgun.AddAmmo(x);
}
and the new pickup script
public class AddHandgunAmmo : MonoBehaviour
{
private EnemyDrops enemyDrops;
private void Awake()
{
enemyDrops = FindObjectOfType<EnemyDrops>();
}
private void OnTriggerEnter(Collider other)
{
if (other.tag == string.Format("Player"))
{
enemyDrops.AddHandgunAmmo(50);
Destroy(gameObject);
}
}
}
As you can see it all still works with passing values through the methods just had to have a "middle man" to relay the information. But this works just fine
Thanks for everyones feedback and I hope this helps someone

Unity3D - enemy not taking damage

In Unity3D my enemy is not taking damage upon colliding with my projectile explosion.
Although this is not the case as it the health variable is unaffected upon colliding with my projectile explosion.
My Enemy and Barrel classes inherit from Entity which handles the taking of damage (subtracting the damage variable from the health variable). Although only the barrel class is working as intended.
The tags are 100% correct and I would prefer to continue using inheritance so please no suggestions to change the method in which my classes take damage.
the class that Enemy and Barrel inherit from
using UnityEngine;
using System.Collections;
public class Entity : MonoBehaviour {
public float health = 25;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
}
public virtual void takeDamage(float dmg){
health -= dmg;
if (health <= 0){
Destroy(this.gameObject);
}
}
}
Enemy class
using UnityEngine;
using System.Collections;
public class Enemy : Entity {
private NavMeshAgent agent;
public GameObject target;
// Use this for initialization
void Start () {
agent = GetComponent<NavMeshAgent> ();
}
// Update is called once per frame
void Update () {
agent.SetDestination (target.transform.position);
}
}
Barrel class
using UnityEngine;
using System.Collections;
public class Barrel : Entity {
private Transform myTransform;
//Effects
public GameObject barrelExplosion;
public GameObject explosionDamage;
public GameObject explosionSound;
// Use this for initialization
void Start () {
myTransform = this.transform;
}
// Update is called once per frame
void Update () {
}
public override void takeDamage(float dmg){
health -= dmg;
if (health <= 0){
Instantiate(barrelExplosion, myTransform.position, myTransform.rotation);
Instantiate(explosionSound, myTransform.position, myTransform.rotation);
Instantiate(explosionDamage, myTransform.position, myTransform.rotation);
Destroy(this.gameObject);
}
}
}
ExplosionAOE the class that sends the damage
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class ExplosionAOE : MonoBehaviour {
public float damage = 100.0f;
public float lifeTime = 0.05f;
private float lifeTimeDuration;
public List<GameObject> damageTargets = new List<GameObject>();
public float radius = 15.0f;
GameManager gameManager;
void Start() {
gameManager = GameObject.FindGameObjectWithTag("GameManager").GetComponent<GameManager>();
//Destroy (this.gameObject, lifeTime);
lifeTimeDuration = Time.time + lifeTime;
transform.GetComponent<SphereCollider>().radius = radius;
}
void Update() {
//Explosion finishes, damage targets and remove AOE field
if (Time.time > lifeTimeDuration) {
foreach (GameObject target in damageTargets) {
if (target != null) {
//Calculate damage based on proximity to centre of explosion
float thisDamage = ((radius - Vector3.Distance(target.transform.position, transform.position)) / radius) * damage;
print(thisDamage);
target.GetComponent<Entity>().takeDamage(thisDamage);
//target.SendMessage("takeDamage", damage); //<< This is not good code. Let's fix this!
}
}
Destroy(this.gameObject);
}
}
void OnTriggerEnter(Collider otherObject) {
if (otherObject.gameObject.tag == "Enemy") {
damageTargets.Add(otherObject.gameObject);
}
if (otherObject.gameObject.tag == "Player") {
Vector3 jumpVector = (otherObject.transform.position - transform.position).normalized;
jumpVector *= 25;
otherObject.GetComponent<CharacterMotor>().SetVelocity(jumpVector);
}
}
}
Sorry this is a bit of a lengthy one and EVERYTHING is tagged correctly so that is not the issue, thanks.
Problem 1.
Use "Debug.Log" everywhere
void OnTriggerEnter(Collider otherObject) {
Debug.Log("in trig");
Debug.Log("otherObject.gameObject.tag is " + otherObject.gameObject.tag);
if (otherObject.gameObject.tag == "Enemy") {
Debug.Log("a");
damageTargets.Add(otherObject.gameObject);
}
if (otherObject.gameObject.tag == "Player") {
Debug.Log("b");
Vector3 jumpVector = (otherObject.transform.position -
transform.position).normalized;
jumpVector *= 25;
otherObject.GetComponent<CharacterMotor>().SetVelocity(jumpVector);
}
}
In particular, in Entity and Enemy.
Questions such as this one are instantly answered by tracking with Debug.Log.
Problem 2.
It's a PITA getting the relationships between triggers, rigidbody, etc.
It's very likely that's a problem here.
http://docs.unity3d.com/Manual/CollidersOverview.html
Go down to the annoying "trigger action matrix" and work from there.
Problem 3.
As a rule, never use the "tags" feature in Unity. (They only added tags to help "hello world" tutorials.)
In practice you use layers everywhere and always:
(Layers are particularly essential in shooting games: every single category needs a layer.)
Problem 4.
The code shown is definitely looking good. Here's some example code not unlike yours for tips.
Trivial example, note the breakaway code (the returns) inside the OnTrigger, you should do that).
Also,
use extentions
everywhere and always in Unity. Quick tutorial
it's the #1 tip if you actually want to work professionally.
