alice-teacher Alice 3.1 World code needed (similar to Greenfoot.stop)

[Grim, Dianne]

Thank you Don!
Yes, the intent is to stop the animation, aka the game.  I will give it a try and let you know the results.
Best to you,

Dianne,
By automatically end, do you mean that the playback window automatically closes and you return to the IDE? Alice does not have that type of command.

If however, you want the animation to stop, but you are not sure exactly when that should happen, then why you might do is create a boolean variable, such as programIsRunning and set it to true. Then create a while loop that controls program execution, with the test condition for the loop being

        while (programIRunnning)

and then set the variable to false when the queen is oriented to the hole.

You could also use this variable to control execution of any events that you may be using, with an if statement testing the programIsRunning variable to fire the event, or not.

Let me know if this does not answer your question…

All the best,
Don Slater
