I'll attach my Megaman codes that carry out the switch along with the insane error i keep receiving: When I hit run again the switch is carried through and I can continue playing, until I try to switch Actors again. It compiles perfectly fine, but when I try to do the switch while running the program I get a crazy error, which in turn stops my program. My idea was that if one were to change the direction (aka hit the left arrow key whilst facing right) then I would replace the current Actor with the a new one which would have the same methods and such as the previous, except the animated gif would be facing the opposite way. I have animated gifs (achieved via the AnimatedActor class) of the two to make the running and jumping seem more realistic. I'm making a little Megaman vs Bass game for myself where two opponents face off as, you guessed it, Megaman and Bass.

The call uses the argument 8 to replace the first while loop and the argument 10 to replace the second loop. View Lecture-using-greenfoot.pdf from CS CS-134 at Johnson County Community College. In Greenfoot, which initially provided only one language, Java. Replace the two while loops with method calls.

Write the method definition in the class Cat: private void twoPlayMoves(int howMany) count = 1 while (count <= how Many) 8. The method's signature had return type void and one parameter, let's call it how Many of type int. Instead of writing two almost identical while loops, we can write a method let's call it twoPlayMoves. How similar are the two while loops you wrote? What makes them different? Answer: number of times the code in the for-loop is executed repeatedly (8, first for-loop, and 10, second for-loop). Is there another opportunity to replace repetitive code with a while lago Comment it out and write a while loop instead. Test your code that uses a while loop with 4 statements instead of 4 statements repeated 8 times 6. Increment your counter variable with the statement 5. Inside ( ) write the three calls that repeat so much: setImage('cat-play-3-piano.png') wait(6): setImage('cat-play-48-piano.png') wait(6) vi. Open bracket (start new line, and close) on another new line. Open (and close ) and inside the parentheses write ne 8 iv. Initialize your counter variable with the statement: n=1 ii. Start a while loop on the line ABOVE the second call to play Sound: Greenfoot playSound('Snoopy.wav), which is online 104.

Select these lines of code and use F8 key (or select Edit-Comment). Comment out the first block of code that uses these three lines repeatedly clines 71 to 102). author Michael Kolling author Denise Lodge author Rebecca Lee author Mihaela Sabin version 2. We can make the cat do the same thing with a while loop in which we use each of the calls identified at #3 only once a. // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)/ A cat.

wait(6), and setImage('cat-play-4B-piano.png'). Returns: The info about the current state of the mouse, or null if the mouse cursor is outside the world boundary (unless being dragged). Which are the lines of code that repeat the most? Answer: setImage['cat-play-3-piano.png'). public static MouseInfo getMouseInfo() Return a mouse info object with information about the state of the mouse. When you have code that repeatedly does the same thing, you can use a while loop to shorten the text of code. We are going to alter the code to use while loops. Describe what is happening in the body of the play method. Use your Greenfoot knowldege: If an Actor class Fly has a variable defined to store the current speed, which of the following statements would successfully add a Fly and define the current speed as 2 Mark for Review. On the cat object placed in the CatWorld, call the playPiano method.
