Is it possible to use UnityEvents and/or UnityActions in scriptable objects?
My attempt looks like this:
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Events;
[CreateAssetMenu(menuName ="Dog", fileName ="New Dog")]
public class Dog : ScriptableObject
{
public string Id;
public string Text;
public UnityEvent WhenFinished;
public GameObject Go;
}
Is it possible to make a scriptable object hold a reference to a GO in the hierarchy or have an event point to a listener in the hierarchy. Is there anyway a scriptable object can communicate with the logic in the hierarchy?
Yes and no.
You can get an SO to GO reference and the reverse, but only during runtime.
When outside runtime, you can only get a SO to GO reference, an SO created in the editor outside of runtime can't reference any game object (it wouldn't know from which scene to get the GO).
Following is the code showing how to achieve this.
Scriptable Object Code
using System;
using UnityEngine;
[CreateAssetMenu(menuName = "Dog", fileName = "New Dog")]
public class Dog : ScriptableObject {
public GameObject Go;
public static event Action<string> ScriptableToGameobjectEvent;
private void Awake() {
EventScript.GameobjectToScriptableEvent += InstanceCreated;
if (Application.isPlaying) {
ScriptableToGameobjectEvent("Dog Created");
}
}
private void InstanceCreated(GameObject go) {
Go = go;
Debug.Log(Go.name);
}
}
Game Object Code
using UnityEngine;
using System;
public class EventScript : MonoBehaviour {
public static event Action<GameObject> GameobjectToScriptableEvent;
public ScriptableObject myScriptable;
private void Awake() {
Dog.ScriptableToGameobjectEvent += DogCreated;
}
private void Start() {
myScriptable = ScriptableObject.CreateInstance<Dog>();
}
private void DogCreated(string str) {
Debug.Log(str);
GameobjectToScriptableEvent(gameObject);
}
}

I'm making a dialogue system in unity, in which a player would walk up to an NPC and press E to trigger a dialogue response, However, when I attempt to access the "Text" Component of the GameObject, I receive two of the same errors:
Assets/DialogueTrigger.cs(28,24): error CS0118: DialogueTrigger.Text is a field' but a `type' was expected
This is the component I am trying to access:
Text (Script)
The component is in This game object:
Game Object
Here is the code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class DialogueTrigger : MonoBehaviour {
public string Text;
public string Name;
public GameObject Dialog;
public GameObject Texta;
public GameObject Namea;
public Collider2D collision;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
}
void OnTriggerEnter2D(Collision col)
{
if (Input.GetKeyDown(KeyCode.E))
{
Dialog.SetActive(true);
Texta.GetComponent<Text>().Text = "Hello!";
Namea.GetComponent<Text>().Text = "Guy";
}
}
}
Any solutions are greatly appreciated.
There's a name conflict between your field named 'Text' and the component type 'Text', so the compiler doesn't understand which one you meant by GetComponent<Text>().
You can resolve this by changing the name of your field to something else, like for example 'text'.
You also don't even need to call GetComponent<Text>() if you change the types of your Texta and Namea fields to Text.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class DialogueTrigger : MonoBehaviour {
public string Text;
public string Name;
public GameObject Dialog;
public Text Texta;
public Text Namea;
public Collider2D collision;
void OnTriggerEnter2D(Collision col)
{
if(Input.GetKeyDown(KeyCode.E))
{
Dialog.SetActive(true);
Texta.text = "Hello!";
Namea.text = "Guy";
}
}
}
I just started to work with scriptableobject, and I'm trying to Instantiate / Create Instance of a very basic scriptableobject that got 4 line of arrays.
I'm trying to Instantiate one scriptableobject that I created, that every time he's been created he will randomize his variables
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[CreateAssetMenu(fileName = "New Character",menuName = "Character Creation/Player Units")]
public class CharStats : ScriptableObject
{
[SerializeField]
public string [] charName;
public string [] charDescription;
public string [] charSin;
public Sprite [] charIcon;
}
The changing I'm doing do inside the inspector for one scriptableobject, and just his inside variables will change every time I create new one. Is it possible to achieve?
Ok so I manage to create something might be not the right way, but after pressing a key ( for now testing) its Instantiate my scriptableobjectwith a random Icon I put on for now. Ill add the 3 scripts, bad names coz it's for testing only, (testing - its script that sitting on empty gameobject with reference to my scriptableobject, testing 2 - its script that sitting on a prefab that I Instantiate with the scriptableobject)
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Random = UnityEngine.Random;
public class testing2 : MonoBehaviour
{
//public ScriptableObject person;
public CharStats charSats;
public Sprite sprite2;
private SpriteRenderer spriteRender;
private void Start()
{
spriteRender = GetComponent<SpriteRenderer>();
GetRandomSprite();
}
public Sprite GetRandomSprite()
{
int randomIndex = Random.Range(0, charSats.charIcon.Length);
Debug.Log(charSats.charIcon[randomIndex]);
if (sprite2 == null)
{
sprite2 = charSats.charIcon[randomIndex];
spriteRender.sprite = sprite2;
}
return charSats.charIcon[randomIndex];
}
}
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Random = UnityEngine.Random;
public class Testing : MonoBehaviour
{
public GameObject Player;
private void Update()
{
SpawnPlayer();
}
public void SpawnPlayer()
{
if (Input.GetKeyDown(KeyCode.A))
{
GameObject spawnPalyer = Instantiate(Player, new Vector3(Random.Range(-10,10), Random.Range(-10, 10)), Quaternion.identity) as GameObject;
}
}
}
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[CreateAssetMenu(fileName = "New Character",menuName = "Character Creation/Player Units")]
public class CharStats : ScriptableObject
{
[SerializeField]
public string [] charName;
public string [] charDescription;
public string [] charSin;
public Sprite [] charIcon;
}
So I am creating a game, which is a Novel game. I want to add a functionality where my friend can add a new dialogue on a character game object. To do that, I already created a main script that enqueue and dequeue all of what is written on the inspector. Two more scripts, one script is a class for creating a new properties on the inspector where my friend can write, the other script functionality is to patch it on the inspector itself. I decided to add a patcher to customize unity editor to add a button. All what is left is a function to add another class where in my friend can write another character name and sentences.
This is what it looks like on Unity Inspector:
Please Help.
DialogueManager.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class DialogueManager : MonoBehaviour
{
private Queue<string> sentences;
public Text WrapperName;
public Text WrapperContent;
void Start()
{
sentences = new Queue<string>();
}
public void StartDialogue (Dialogue dialogue)
{
WrapperName.text = dialogue.name;
sentences.Clear();
foreach (string sentence in dialogue.sentences)
{
sentences.Enqueue(sentence);
}
DisplayNextSentence();
}
public void DisplayNextSentence()
{
if(sentences.Count == 0)
{
EndDialogue();
return;
}
string sentence = sentences.Dequeue();
WrapperContent.text = sentence;
}

{
Debug.Log("dialogue Ended..");
}
}

}
StoryElement.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class StoryElement : MonoBehaviour
{
public Dialogue dialogue;
public void TriggerDialogue()
{
FindObjectOfType<DialogueManager>().StartDialogue(dialogue);
}
}
elementscriptpatcher.cs
using System.Collections;
using UnityEditor;
using UnityEngine;
[CustomEditor(typeof(StoryElement))]
public class elementscriptpatcher : Editor
{
public override void OnInspectorGUI()
{
DrawDefaultInspector();
if(GUILayout.Button("Add another script"))
{
// I need to write a function for appending a class Dialogue on Dialogue.cs which was initialized on the StoryElement.
}
}
}
you can use GameObject.AddComponent.
if(GUILayout.Button("Add another script"))
{
gameObject.AddComponent<Dialogue>();
}
EDIT : As #derHugo said in comments, we can't add a class that's base is not Monobehaviour. So you will require an Access Class to access Dialogue.cs.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class AccessClass : MonoBehaviour {
public Dialogue mClassObject;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
}
}
Use Ink for Unity, and author the dialogue as text files.
I'm trying to get the title/description of a playing card to change by creating a card class that holds the information:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[CreateAssetMenu (menuName = "Card")]
public class Card : ScriptableObject
{
public string cardName;
public Sprite art;
public string cardDetail;
}
Then load it with another script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class CardViz : MonoBehaviour
{
public Text title;
public Text detail;
public Image art;
public Card card;
private void start()
{
LoadCard(card);
}
public void LoadCard(Card c)
{
if (c == null)
{
return;
}
card = c;
title.text = c.cardName;
detail.text = c.cardDetail;
art.sprite = c.art;
}
}
I created prefab with the basic layout of a card. Then I created a new asset value in unity for a card and given it a name and detail. Then assigned it to the public valuable Card under CardViz along with the corresponding title, detail and image variable to create a new prefab but none of the text change when I drag the newly made prefab into the hierarchy. Any clue as to what I'm doing wrong here?
A small typo. Your start method needs to have a capital s.
private void Start()
{
LoadCard(card);
}
I am trying to make it so that collecting an item will cause the score to increase. After perusing the documentation for Unity, I have written the following C# scripts. CollectableItem.cs is attached to the items in the game. ScoreBoard.cs is attached to the UI display. I'm getting the error message, "'ScoreBoard.score' is inaccessible due to its protection level." If I make the variables in ScoreBoard.cs public, I get a different error message: "An object reference is required for the non-static field, method, or property 'ScoreBoard.score'."
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class CollectibleItem : MonoBehaviour {
[SerializeField] private string itemName;
[SerializeField] private int pointsValue;
void OnTriggerEnter(Collider other) {
Managers.Inventory.AddItem(itemName);
Destroy(this.gameObject);
ScoreBoard.score += pointsValue;
}
}
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class ScoreBoard : MonoBehaviour {
[SerializeField] private Text scoreLabel;
private int score;
void Start () {
score = 0;
}
void Update () {
scoreLabel.text = "Score: " + score.ToString();
}
}
UPDATE: Here is Take 2 on CollectibleItem.cs. Now I'm being informed that "board" does not exist in the current context...
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class CollectibleItem : MonoBehaviour {
[SerializeField] private string itemName;
[SerializeField] private int pointsValue;
void Start() {
var uiObject = GameObject.Find("Timer");
ScoreBoard board = uiObject.GetComponent<ScoreBoard>();
}
void OnTriggerEnter(Collider other) {
Managers.Inventory.AddItem(itemName);
Destroy(this.gameObject);
board.score += pointsValue;
}
}
This is not able to work because you make a so-called static access to the ScoreBoard class. That means you try to change the variable of the ScoreBoard class. What you want to do is to change the variable on one of the instances. When the UI Object is created, an instance of the class of your ScoreBoard-Script is created. Like every item has its own instance of CollectibleItem.
You can get the instance in this way:
var uiObject = GameObject.Find("Name of UI Object");
ScoreBoard board = uiObject.GetComponent<ScoreBoard>();
You can do this in Start() and save the ScoreBoard variable in the script where your other private variables reside and use it later in the trigger, or you can do this directly in your Trigger function and directly set the score:
board.score += pointsValue;
EDIT: You have to place the declaration of Scoreboard inside the class:
ScoreBoard board;
void Start ()
...
Or put the code from start to OnTriggerEnter.
