It's very easy.
1. You may create a several skins for your clock. For example: skin1.png, skin2.png, skin3.png etc...
2. Then you need add a "states" into clock background object which corresponding to these skins. For example: skin1, skin2, skin3 etc...
3. After that you can use a simple code like this:
Dim num, total
Sub Object_OnScriptEnter
num = 1
total = 10 '<== or any other number (this is a total amount of your skins)
End Sub
Sub Object_OnStateChange(state)
If state = "Command executed" Then
desktopx.object("My Clock").state = "skin"&num
If num < total Then num = num + 1 Else num = 1
End If
End Sub
The clock faces will be changing step by step when you click on it.
Have a nice days with DesktopX.
