Dear friends, please,

I am using Java 11 and I have code:

B4X: 
Yes in B4J / No function in standalone:
                         robot.InitializeNewInstance("javafx.scene.robot.Robot", Null)
                         robot.RunMethod("mouseMove", Array As Object(x,y))
Yes in B4J / No function in standalone:
                          Private robot As JavaObject
                          Dim jo As JavaObject
                          jo.InitializeStatic("com.sun.glass.ui.Application")
                          robot = jo.RunMethodJO("GetApplication",Null).RunMethodJO("createRobot",Null)
                          Dim x As Double =123
                          Dim y As Double =100
                          robot.RunMethod("mouseMove", Array As Object(x, y))  
Yes in B4J / No function in standalone:
                          x=205
                          y=200
                         Dim robot As JavaObject
                         robot.InitializeNewInstance("javafx.scene.robot.Robot", Null)
                         robot.RunMethod("mouseMove", Array As Object(x, y))

- When I am running app in B4J then everything is functioned
- but when I have stand alone package, then cursor is not moving

Why please? Where I am doing mistake?
Best regards

If it runs in the IDE environment then your program code looks ok. The only difference between the IDE and standalone package is that in the standalone version things go faster because the overhead of the IDE is missing. So it is possible that your next program step is already executing while the previous step is not completed.

To eliminate that, just add a sleep(5000) delay to see if it works. If it works, then lower the sleep instruction. You can also record a log time after each step to see how much time is used in IDE execution. It's just trying to find the solution.

You could also look to the time ticks needed for the different steps with the following code:

Log Time ticks example: 
    Dim Ticks As Long = DateTime.now...

You can give time for a screen update to see what happening with the following code:
Screen update: 
    sleep(0)    ' you can increase the value if necessary in steps of 1 msec after each Java call.

Yes MicroDrie, I have this. I can not move cursor. Click is functioned, but moving not.

Are there any errors? Run from the run_debug.bat file and check the console window.
