alice-teacher Alice 3 Event Listener Question

[Joel Caulum]

Don,

Could you send a code sample, preferably in Alice 2, showing an example of what you described here?


Thanks,

Emily,
One solution would be to create a Boolean variable for the Scene / World, maybe called isActive, with an initial value of true.

In the event, create an if... statement
        if (isActive)

And then the work of the event would be inside the if statement code block...

You would set the isActive variable to false at the point in the program where the user should NOT be able to move the wolf.

Let me know if you have any questions...

All the best,
Don Slater
