Question

我正在实例化带有RectTransform组件和个人脚本（某些Monobehaviour）的预制件。

我完全可以将此实例化的预制件作为所需的GameObject的父级，甚至可以设置其localPosition.x值和localPosition.z值，但不能设置其Y值。

目标是实例化此预制件，并对其进行实例化，然后用一个新的实例进行重复。

旧的预制件应向上移动，以便让新的实例代替它。

我可以更改其localPosition X和Z值，如（1234，y，5678），但Y保持为0。始终。

这是代码：

脚本A：https://pastebin.com/Q5jqy6rz
脚本B：https://pastebin.com/64sChs3S

注意。每个实例都作为其父对象的GameObject仅具有RectTransform组件，Image组件，Script A和CanvasRenderer组件。

/*Script A, this is part of the script were I instantiate the game object*/

             /*Fields:*/

             private LineTPA CurrentLine; //last Line created
             private List<LineTPA> listLinesTPA; //Where I keep reference to each line created.

             [Serializedfield] GameObject PrefabLineTPA; //Ref to the prefab I'm instantiating.

             //Position where I want each new Line to be:
             private Vector3 StartPosition = new Vector3 (someX, someY, someZ); 

             /*Methods: */

             private void CreateNewLine()
             {
                 //Instantiating:
                 GameObject GOinstance= Instantiate(PrefabLineTPA);
                 GOinstance.transform.SetParent(this.transform, worldPositionStays:false);

                //Getting the Monobehaviour from the GameObject:
                CurrentLine = GOinstance.GetComponent<LineTPA>();

                //Keeping a reference to the script for later.
                listLinesTPA.Add(CurrentLine);

                //The script needs some parameters to start working.
                CurrentLine.InitiateMe(/*some parameters*/); 

                //Placing the object in the position that I want.     
                CurrentLine.MyPosition= StartPosition; 
                //It gets the X and Z, but the Y stays on 0. 
             }

             private void CreateSpaceForNewLine()
             {
                 foreach(LineTPA line in listLineTPA)
                 {
                     line.MoveUp();
                 }
             }

/*Script B, this is part of the LineTPA script, it's a component on the Prefab. */

             //In the prefab, this field is given through the editor:
             public RectTransform rectTransform; 

             //Just some shorthand props:
             public Vector3 MyPosition
             { 
                get => rectTransform.localPosition; 
                set => rectTransform.localPosition = value; 
             }

             public float MyHeight => rectTransform.rect.height;
             //-----------------------------------------------------

             public void InitiateMe(/*some parameters*/)
             {
                /*gets references for some stuff*/                
             }

             /// <summary>
             /// Called from ScriptA.
             /// </summary>
             public void MoveUp()
             {
                 float sameX = MyPosition.x;
                 float sameZ= MyPosition.z;

                 //Here's where I try to change the Y position
                 float newY = MyPosition.y + MyHeight ;
                 //-------------------------------------------
                 
                 MyPosition = new Vector3(sameX , newY, sameZ);
             }

任何帮助将不胜感激。

好吧，我最终添加了VerticalLayoutGroup组件（如@derHugo的建议），它完成了工作。我不知道为什么只有Y值没有变化。

编辑：之所以不能更改游戏对象的rectTransform是因为我的动画控制器。

无法在Y轴上移动RectTransform.localPosition。仅在Y轴上
