动态地向游戏对象添加脚本并为其属性分配值 [英] Adding a script to a game object dynamically and assigning values to its properties

问题描述

我想向游戏对象添加脚本/组件并在该脚本中填充值.输入值来自父对象"LineManagerProperty".在下面的示例中，我想将"LineManager"类添加到"Line"游戏对象，并在"LineManager"中分配属性.如果您查看"Line"类，则添加"LineManagerProperty"，以便它可以作为值传递到"LineManager"中，并出现在统一检查器中.有更好的方法吗?

I want to add a script/component to a game object and populate values in that script. The values for input come from the parent object as 'LineManagerProperty'. In the example below I want to add the 'LineManager' class to the 'Line' game object and assign the properties in 'LineManager'. If you look at the 'Line' class I add 'LineManagerProperty' so that it can appear in the unity inspector as values to pass into 'LineManager'. Is there a better way to do this?

public class Line : MonoBehaviour
{
    //This is added here so that values can appear in inspector
    //These values will be passed into 'LineManager' when its created and added to 'Line' game object
    public LineManagerProperty LineManagerProperty;

    void Update()
    {
        if (Input.GetMouseButtonDown(0))
        {
            //Add the 'LineManager' script and assign its properties
            gameObject.AddComponent<LineManager>().LineManagerProperty = new LineManagerProperty()
            {
                CollisionTag = LineManagerProperty.CollisionTag,
                MaxTimeDuration = LineManagerProperty.MaxTimeDuration,
                NumberOfHits = LineManagerProperty.NumberOfHits,
                Health = LineManagerProperty.Health
            };
        }
    }
}

public class LineManager : MonoBehaviour
{
    public LineManagerProperty LineManagerProperty;

    //...
}

[Serializable]
public class LineManagerProperty
{
    public string CollisionTag;
    public float MaxTimeDuration;
    public float NumberOfHits;
}

推荐答案

我不明白您想要什么，您是否想在检查器中看到LineManager，或者什么，但是我会尽力帮助.我猜您正在创建一些编辑器，而又不想将LineManager保存在预制件中.

I don't understand what you want, do you wanna see LineManager in inspector or not, or what, but i will try to help. I guess you are creating some editor and you don't want to save LineManager in prefab.

idk，也许它将为您提供一些想法.

Maybe it will give some idea for you, idk.

#define EDIT_MODE // if you delete this, code in EDIT_MODE fields will ignored and never compiled
using UnityEngine;
public class Line : MonoBehaviour {
    public LineManagerProperty lineManagerProperty;
#if EDIT_MODE
    LineManager lineManager;
#endif
    void Start() {
#if EDIT_MODE
        lineManager = new LineManager(lineManagerProperty);
#endif
    }

    void Update() {
#if EDIT_MODE
        lineManager.Update();// if you want to call something
#endif
    }
}

public class LineManager  {
   public LineManager(LineManagerProperty lmp) {
       LineManagerProperty = lmp;
   }

   public LineManagerProperty LineManagerProperty;

   public void Update() { // if you want to call something
   }
}
