This vertical scrolling shooter features a detailed background, many enemies, and new powerups in the Extended mode only. This is a recommened game for Phoenix fans. PaRappa The Rapper is a game of reflexes. Did you try your code? Did you fix any errors? It is very important you check your code as you go. It makes finding and fixing errors easier. Our piano keyboard has 14 keys on it.

You could make 14 IF statements to play each note based on the light level. How could we use a mathematical relationship to help decrease the number of lines of code? Depending on your light source, the brightness B can range from 0 to Therefore, we need to split the range of values over 14 keys.

If we split the values evenly, we get the equation:. That means the frequency should change each time the brightness increases by 7. Lets say B, the brightness, is To get n for the formula, you need the integer part of result. How do you think you should modify your code to play the right note?

Note: If you have a darker room, you might have to change your value of 7. In order to draw a point on the selected key, you need to know if the exponent numerator, N, matches a sharp or a flat.

Store these values in two different lists. Natural list :. Notice there are two negative 1s in the list. We need to save a space for the missing keys. Recall in the piano Mini Project 1, you wrote the code to highlight all the natural keys. Recall in Mini Project 1, you wrote the code to highlight all the sharp keys. Insert Alpha Graph seven blank lines above the last End statement in your code. Check your answer with the next step. Can you play a song with your piano? You can choose either approach, depending on the availability of materials.

Create a temporary project named T. Type the following lines of code. Do not type the code, get the code from the menu. Now type the rest of the program, after the 'Connect Ranger' command:. On the first line, use recall to import the keyboard code:. It should draw the keyboard first, then display the brightness sensor data. The display should override your keyboard, which is okay for now. Delete the three lines of code that uses the brightness sensor.

You will insert code to read from the ultrasonic ranger instead. Insert the statements to read from the Ultrasonic Ranger Module. Using the numbers from your investigation and Mini Project 3, what do you think goes in the empty line to produce the various notes?

Hover your hand over the sensor. What types of values do you get? Remove the three lines of code from the brightness sensor. Using the numbers from your investigation and Mini Project 4, what do you think goes in the missing line to produce the various notes? If your ranger is reading in meters, most of your numbers in the temporary project were under 1. If you multiply the distance by , your distance values will be about the same as the brightness variables from Mini Project 3.

Therefore, we can use the following code:. In this project, you will write a program that draws a musical note on a staff that corresponds to the tone played. Change the orientation of the screen so 0, 0 is in the lower left and the value increase as you go up the screen. Put ClrDraw as your first line of code [2 nd ][ prgm ]. This will clear any old drawing off the screen. Use the [vars] menu to set the window using the following four statements.

Write a FOR loop to draw the five lines of the musical staff on the board. This particular scale starts at E. Each note has a y-value. Store each value in a list so you can use the heights later. You will also use a list to determine IF you need to draw a sharp. You will use 0 to represent a natural note and a 1 to represent a sharp note. Create a variable K to store key press values. If the user pressed the clear key 45 , the While loop repeating your code will terminate.

You need to create a variable T to store the last note played. Store 0 as the first value for K. Store 0 as the first value for T. There are 13 values stored in L 1 and 13 in L 2. Can you code the following? Draw the new note as a circle with a center at 5, L 1 B and a radius of 0. Set the circle color to magenta or any other color of your choosing.

Remember L 2 has 1s and 0s stored representing the sharp note. If the value in L 2 B is a 1, draw a sharp sign. The scale starts at E, so In order to get E, the exponent needs to be 0. Subtract 1 from the B value for the exponent. Try dividing by values other than 8. Optimize this value for the brightness level in your setting. All rights reserved.

TI Codes: TI Plus Technology Encourage students who have some programming experience to build on their knowledge with activities that take them a little deeper into coding. Guessing Game. Write a Simple Guessing Game The guessing game includes several components: 1. Variable N and randInt used to pick the number to guess.

A Repeat loop that repeatedly asks for a guess until the player guesses correctly. The Prompt command used to get a guess from the player. If conditionals and Disp used to tell the player if their guess is too high or too low. Variable M and Disp used to track and report how many guesses the player made. Guessing Game Last. Try putting the simple guessing game together.

First Introduction. How it Works Last. How it Works. How the Guessing Game Works The diagram below is a flowchart of how the program works. First Guessing Game. Step 1 Last. Step 1. First How it Works. Step 2 Last. Step 2. First Step 1. Step 3 Last. Step 3. First Step 2. Step 4 Last. Step 4.

First Step 3. Step 5 Last. Step 5. The game in this lesson picked a number between 1 and Display the range in which the player should be guessing, here 1 to Keep track of the high score the lowest number of guesses made. You could keep track of other statistics as well, like the average number of guesses or the worst score the highest number of guesses.

To store information in more permanent locations than the numeric variables A-Z, take a look at the information on custom lists. Use Input instead of Prompt to ask for a guess. First Step 4. Event Loops. Event Loops and getKey The following diagram shows the basic structure of an event loop-based program. There are three major components of an event loop: An escape condition that defines when the event loop stops repeating. In a computer program, an escape condition might be something like exiting from the program or pressing [ESC].

Non-event code. However, in other programs, this is code that runs regardless of whether events occur or not. Conditional statements allow you to control whether sections of code are executed. Conditional statements consist of a condition that can be true or false, and code that is executed if the condition is true.

The simplest form of conditional on your calculator consists of the condition on one line, followed directly by a second line of code that is run if the condition was true or skipped if the condition was false. Step 6 Last. Step 6. First Step 5. Step 7 Last. Step 7. First Step 6. Step 8 Last. Step 8. First Step 7. Step 9 Last. Step 9. First Step 8. Step 10 Last. Step If the left arrow key was pressed, we want to subtract 1 from the x -coordinate so that the M will move one space to the left.

First Step 9. Step 11 Last. First Step Step 12 Last. Step 13 Last. An easy place to start would be to make something other than an M move around the screen. Perhaps a different letter? Or a group of letters in a shape? Handle diagonal movement so that the letter can move in 8 directions instead of just 4.

Which commands do you need to change, and which stay the same? What are the new bounds you need to use to keep the text from going off the screen? How can you implement a weapon, and keep track of where the asteroids are and the score? You can, of course, also use your imagination to think of features you want to add. Step 14 Last. X is the length of the snake, here, 10 segments.

As the snake moves, P moves as well, so that it always points to the end of the snake without having to move the data in L1 and L2 forward. D is the direction in which the snake is heading. In this version, we used P as both the head and tail pointer, because the circular buffer was always completely full. This will lead you to some interesting design decisions: should you start with lists as large as the snake could possibly grow? Or should you expand the lists when the snake is in danger of outgrowing the buffers?

Some approaches store the contents of the homescreen in a matrix, so you can easily test which spots on the homescreen are occupied. You can go even further and add things like walls and differently-shaped levels.

If you do this, you might want to strongly consider the matrix approach to easily detect when the snake has hit a wall or its own tail. Maze New. Along the way you will learn how to: 1. Step 1 Last MP2. Step 2 Last MP2. Step 3 Last MP2. Insert the following IF statement before the display line. Step 4 Last MP2. Last MP2. In this mini project, you will learn how to store your name as a string. You will use the getKey command from the first project to move your name on the screen.

This project will teach you how to move objects similarly to how you will move your shape for the maze project. Step 1 Last MP3. Step 2 Last MP3. Use the variable K to store the value from the key press Use a WHILE loop to continually get key press values until the clear key is pressed You will need four IF statements, one for each arrow key Do you remember the arrow key numbers from Mini Project 1?

What do you think the IF statements will look like to control the movement of the string? Step 3 Last MP3. Step 4 Last MP3. Step 5 Last MP3. Step 6 Last MP3. Error trapping The row and column variables have to be larger than 0.

To color one pixel the code is: Pxl-On row number, column number, color To create a blue rectangle that has a width of five and a height of two, type the code below.

All other commands are under DRAW 2nd prgm. Step 2 Last MP4. Modify your code. Following these instructions shows you how to program using the Texas Instruments 84 Plus.

These instructions are intended for beginners in programming, there is no need to know any programming knowledge prior to these instructions. It is important for users new to the TI Plus to carefully go through the instructions and get familiar with buttons that are used. We will be using every button that is mentioned. Programs help users whom execute many of the same computations clerically.

While programs can help get to an answer more efficiently, it is not always the best practice to use programs in situations like: learning new material, practicing mathematical assignments, and taking exams. In many cases this can lead to an accusation of cheating, even if you created the program yourself. It is important to check with your professors before using programs on exams! The only required equipment that is essential to completing these instructions is the Texas Instruments 84 Plus Graphing Calculator.

There are many other versions of this calculator that will work with these instructions, but we will cover the instruction using the TI Plus. The green letters above buttons correspond to the alphabetical buttons. While inside you program, you can find commands by pressing PRGM.

INPUT [ Input ] : This command lets you create a variable under any arbitrary alphabetical character and will prompt the user to enter a value. Navigate to the programming screen by pressing the PRGM button. The next screen prompts you to enter a name. Choose a suitable name for your program e. You should still be inside the text editor. Begin creating a menu by pressing PRGM once more.
