[New UI] Set anchors from script

Questions & Answers
1

Is there a way of setting anchors from script, but using values set from GUI (Center, Middle etc. without specifying number values)?

I dont think you can do that. But you can set them using the AnchorMin & AnchorMax (Both Vector2) properties of the rect transform. So thus

              Bottom Left corner would be
                               X Y
                         Min=>[0,0]
                         Max=>[0,0]

              Bottom Right corner would be
                               X Y
                         Min=>[1,0]
                         Max=>[1,0]

              Top Left corner would be
                               X Y
                         Min=>[0,1]
                         Max=>[0,1]

              Top Right corner would be
                               X Y
                         Min=>[1,1]
                         Max=>[1,1]

                     Center would be
                               X    Y
                         Min=>[0.5,0.5]
                         Max=>[0.5,0.5]

So for example to set your anchor to top left corner :

transform.GetComponent<RectTransform>().AnchorMin = new Vector2(0,1);

transform.GetComponent<RectTransform>().AnchorMax = new Vector2(0,1);

Hope this helps. :slight_smile:

Thank you very much :slight_smile: Do you know if there is a way of achieving from script the effect as when setting anchors in inspector holding “alt”? I mean, to change position along with anchors, or should I calculate it manually?

TextAnchor is an enum, you should call it by ising TextAnchor.“seedocsforalltypes”

Using UnityEngine.UI;

public Text text;

text.alignment = TextAnchor.UpperLeft;

I wrote myself a pretty neat script to easily test whatever I need

SetAnchor.cs

using System; using System.Collections;  using System.Collections.Generic;  using UnityEngine; 

public class SetAnchor : MonoBehaviour {

public float x = 0;
public float y = 0;

public float aminx = 0;
public float aminy = 0;

public float amaxx = 0;
public float amaxy = 0;

public float apivotx = 0;
public float apivoty = 0;

void Start()
{
    setAnchor(this.GetComponent<RectTransform>(), this.transform.parent.GetComponent<RectTransform>());

}

private void Update()
{
    setAnchor(this.GetComponent<RectTransform>(), this.transform.parent.GetComponent<RectTransform>());
}

private void setAnchor(RectTransform rectTransform1, RectTransform rectTransform2)
{
    rectTransform1.anchoredPosition = new Vector2(x, y);
    rectTransform1.anchorMin = new Vector2(aminx, aminy);
    rectTransform1.anchorMax = new Vector2(amaxx, amaxy);
    rectTransform1.pivot = new Vector2(apivotx, apivoty);
    //rectTransform1.sizeDelta = rectTransform2.rect.size;
    //rectTransform1.transform.SetParent(rectTransform2);
}

}

When you are done testing. Comment or Delete the Update Methode.
