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.
