Submit an Alice A2W file and either a flowchart or pseudo-code for each of the following projects:

• Leaving on a Jet Plane: Create a world with an array containing three Grayjumpjets (Web Gallery). You may have to resize the objects. Have each jet lift off the ground, one at a time. Together, all three should turn and fly off together. Reference the objects by their array name and index. For the first part (each jet lifts off the ground), use a loop structure, and reference the jet using the loop variable. For the second part (turn and fly off together) you won't be able to use a loop structure, but still refer to the objects using their array name and index.

• Helicopter Squadron: Create a world with a list containing four Helicopters (Local Gallery). Again, you may have to resize them to fit in the world's view. Either together or one at a time, each helicopter should have its rotor turn (Alice calls the rotors propellers, but they're really called rotors); the rotors should stay turning throughout the entire playing of the world. Then, the helicopters rise to the same height one at a time, still in the camera's view. A message should appear from each windshield (note: from the windshield, not just from the helicopter), one at a time, indicating its readiness for the mission. Then, all four helicopters should move out of the camera's view, together, in the same direction. Once started, each helicopter's propeller should turn throughout the story. Reference each object by its list name.

For the first part (starting the rotors spinning), you will probably need to use four separate instructions (one for each helicopter propeller, as opposed to a loop or something like that). You could probably get it to work with a for all... construct, but you would probably have to come up with a method to do the spinning, and then call that method inside a do together.

For the 'message' part, you'll probably need four separate instructions as well.

For the second part (rising up one at a time) do not use four separate move instructions. There's a list construct that lets you do what you want; use it!

For the last part (move off camera together), do not use a do together construct. There's a list construct that lets you do what you want; use it!
