How to replace Texture2D.Reinitialize()? Unity 2020.3 does not have this function

Question

I updated my Unity project to Unity 2020.3.18 and I get this error:

'Texture2D' does not contain a definition for 'Reinitialize'

According to doc, the class Texture2D suddenly doesn't have function Reinitialize() https://docs.unity.cn/2020.3/Documentation/ScriptReference/Texture2D.html

So without this function, I assume I'll have to use constructor instead?

Old code:

 Texture2D tex;
 int newWidth;
 int newHeight;
 
 //get newWidth & newHeight
 
 tex.Reinitialize(newWidth, newHeight);

New code: replace tex.Reinitialize(newWidth, newHeight); with this

 tex = new Texture2D(newWidth, newHeight, tex.format, false);

My question is, was my new code correct? Does it do the same thing that Reinitialize was doing?

The constructor's 4th parameter is "bool mipChain", I don't know what value I should pass for this parameter

I have never seen this function before and it isn't on any docs pages in the Unity archive (Unity 5+) so it was probably either a function for internal use or was deprecated a very long time ago before finally being removed. The replacement you are probably looking for is Texture2D.Resize()

https://docs.unity.cn/2020.3/Documentation/ScriptReference/Texture2D.Resize.html

Make sure to call tex.Apply() afterwards.

In Unity 2020.3, the Reinitialize() method got replaced with Resize()

So, change the following line

 tex.Reinitialize(newWidth, newHeight);

like this

 tex.Resize(newWidth, newHeight);
 // or
 tex.Resize(newWidth, newHeight, tex.format, false);

NB: If you are using Unity 2019.4, 2021+ versions then you can use the Reinitialize() method for changing the texture size.
