Lesson 21. Controlling Sprites with Lingo > Using if-then to Set Limits

Using if-then to Set Limits

Did you notice that the arm moves off the stage when it reaches the top or bottom? You can fix this problem by adding limits to the arm movement. You'll do that now by using the Lingo construct if-then. You used this in a previous lesson.

Note

If you did not complete the preceding tasks, open Start2.dir in the Lesson 21 folder to continue with this lesson.
