Backup unity project
https://www.shiftescape.com/2024/07/which-all-files-and-folders-to-backup.html

In order to be able to recreate the Unity Project from a backup zip, just remove Library and Temp folder when backing up the project to a zip file.



What's in there?

- Drawing Board Drag for moving objects while holding them, zooming in using mouse scroll and pinch zoom for touch devices.

- SimpleAES for encrypting and decrypting content.

- Orientation Manager for forcing a certain orientation on Android Devices

- Photon Connect contains a very robust Photon Matchmaking Example using Hashtable for Room Properties and Player Properties.

-SSUpload for taking screenshot of unity screen - flipping the textures and uploading screenshot using REST API.

############### for input to upper case ################
########################################################


        
public InputField inputField;
this goes to start function:

  inputField.onValidateInput += delegate (string input, int charIndex, char addedChar) {
        return nameValidation(addedChar);
  };
and this is the addedChar function that does the control and modification on per character basis:

 private char nameValidation(char c)
 {
     if (c >= 'A' && c <= 'Z') {
         return (char)((int)c - 'A' + 'a');
     }
     else if ((c >= 'a' && c <= 'z') || (c >= '0' && c <= '9') || c == '_' || c == ' ') {
         return c;
     } else {
         return '\0';
     }
 }

no more onChange causing more change!


And here's an even simpler function to force uppercase...

 void Start()
 {
     your_input.onValidateInput += 
         delegate (string s, int i, char c) { return char.ToUpper(c); };
 }
 
And if you want ONLY letters:

 void Start()
 {
     your_input.onValidateInput += delegate (string s, int i, char c) { return char.ToUpper(c); };
 }
 
 char Val(char c)
 {
     c =  char.ToUpper(c);
     return char.IsLetter(c) ? c : '\0';
 }

Here's uppercase letters only, and a length limit:

     your_input.onValidateInput += delegate (string s, int i, char c)
     {
         if (s.Length >= 4) { return '\0'; }
         c = char.ToUpper(c);
         return char.IsLetter(c) ? c : '\0';
     };

(Alternately, don't forget the very handy .CharacterValidation approach. It is often all you need:)

 void Start()
 {
     your_input.characterValidation = InputField.CharacterValidation.Alphanumeric;
 }


So when using .onValidateInput the .Net "char." functions are very handy.
