App Inventor Summative Project 1 - Rock, Paper, Scissors

From the App Inventor Media Library download the RockPaperScissors_Start.aia file.  Then in AppInventor under PROJECTS, select Import Project (.aia) from computer.  Select the file .aia file you downloaded and begin.

Create an app so that the user can play Rock, Paper, Scissors against the computer. Use the included images.

Add another image control to hold the Player images.

Add two more buttons so that you have three. (Rock, Paper, Scissors) 

When the user clicks on one of the buttons the appropriate Player image will be displayed in the player image control and a random Computer image will display in the Image_Computer control.

App Inventor #6 - Mini-Golf Fling App

Mini-Golf Planning Document (do this before programming the app) Make a copy and then complete.

Create a Mini-Golf app to include the following:

• The screen will include the following: two balls (golf ball and hole), two image sprites (obstacle and tee box), reset button, Hole# label, and a # of strokes label.
• Golf ball will move with the fling event.  After being flung the ball should slow down and eventually stop.  Each fling is one stroke.
• After starting the app the location of the hole, obstacle and tee box will randomly set.  The hole on the top third of the screen, the obstacle in the middle and the tee box at the bottom.  The golf ball will randomly appear on top of the tee box.
• When the ball touches the hole the "Golf Ball in Cup" sound will play then the app will set up the next hole or end the game.
• Variables will track and display the number of strokes and the current hole number.  
• The game will end after the 9th hole.

Challenge Enhancements:

• Add an appropriate sound for every time the user swings(Flings) the ball.
• Add a Water hazard object that randomly appears on the form.  If the ball hits the water then the ball is returned to the tee box and a penalty stroke is added.
