        countName  ;

}

I'm checking if descriptionContent is not empty but even if it does it's entering inside like it's not empty :

In the editor the variable savedGameDescriptionText is a TextMeshPro - Text (UI) and it's empty. what is not empty is the Placeholder :

The Enter description text is in the Placeholder not the savedGameDescriptionText :

The Placeholder contain the Enter description text :

When i click on the Save ui button in the editor it's calling the Save method.

I want that only if the Text(savedGameDescriptionText) is not empty then create the description text file. it seems like checking for "" is not working as i expected.

CodePudding user response：

I suspect the string comparison is dangerous. Try savedGameDescriptionText.text.Equals("") or just see if it's length is 0 like savedGameDescriptionText.text.Length == 0

CodePudding user response：

The problem is that i tried to get direct access to the child text but what i had to do is to get access to the inputfield : TMP_InputField and then to the TMP_InputField text.

This is working :
