unity scriptableobject and scriptable objects code example

Example 1: unity scriptable objects

using UnityEngine;

[CreateAssetMenu(fileName = "Data", menuName = "ScriptableObjects/SpawnManagerScriptableObject", order = 1)]
public class SpawnManagerScriptableObject : ScriptableObject
{
    public string prefabName;

    public int numberOfPrefabsToCreate;
    public Vector3[] spawnPoints;
}

Example 2: ScriptableObject

using UnityEngine;

public class Spawner : MonoBehaviour
{
    // The GameObject to instantiate.
    public GameObject entityToSpawn;

    // An instance of the ScriptableObject defined above.
    public SpawnManagerScriptableObject spawnManagerValues;

    // This will be appended to the name of the created entities and increment when each is created.
    int instanceNumber = 1;

    void Start()
    {
        SpawnEntities();
    }

    void SpawnEntities()
    {
        int currentSpawnPointIndex = 0;

        for (int i = 0; i < spawnManagerValues.numberOfPrefabsToCreate; i++)
        {
            // Creates an instance of the prefab at the current spawn point.
            GameObject currentEntity = Instantiate(entityToSpawn, spawnManagerValues.spawnPoints[currentSpawnPointIndex], Quaternion.identity);

            // Sets the name of the instantiated entity to be the string defined in the ScriptableObject and then appends it with a unique number. 
            currentEntity.name = spawnManagerValues.prefabName + instanceNumber;

            // Moves to the next spawn point index. If it goes out of range, it wraps back to the start.
            currentSpawnPointIndex = (currentSpawnPointIndex + 1) % spawnManagerValues.spawnPoints.Length;

            instanceNumber++;
        }
    }
}
