[v1] Soft mask problem with default mask and resolution change about softmaskforugui

[Andrea332]

I presume the problem is when OnRectTransformDimensionsChange is called in the soft mask component

Hey, I have got the same issue in my project.

I have discovered that de-activating and re-activating a parent of the broken SoftMask GameObjects fix them.

So I have just made a dirty workaround with the following script.
It simply de-activate and re-activate its own gameObject when a RectTransformDimensionsChange happen.

Of course you have to put this Script on a parent of the broken SoftMask GameObjects.

using UnityEngine;

[HelpURL("https://github.com/mob-sakai/SoftMaskForUGUI/issues/157#issuecomment-1691486145")]
public class ReActivateOnResize : MonoBehaviour {

    void Start() { }

    void OnRectTransformDimensionsChange() {
        if(isActiveAndEnabled) {
            gameObject.SetActive(false);
            gameObject.SetActive(true);
        }
    }

}

This is not perfect:

• the GameObjects disappear temporally while the window is resized
• side effects might occur with other Scripts/UI components expecting the GameObjects to be active

Of course instead of using my script you can replace all default Unity Masks by SoftMasks, but in my case I prefer using SoftMasks only when necessary (to avoid putting SoftMaskable components everywhere).

I resolved this issue by adding

protected void OnRectTransformDimensionsChange()
{
   OnValidate();
}

to SoftMaskable.cs
