Cave Adventure

A text-only adventure written in Scratch. Update: I have posted a walk-through in this forum post: http://scratch.mit.edu/forums/viewtopic.php?pid=240980#p240980 This project lets you play a small, text-only adventure pretty much like they did in the mid-70’s. It’s based on the original Colossal Cave adventure by Willie Crowther and Don Woods. The program has built-in hints, help, and info. Be sure to use the down-arrow key instead of the Enter key. If you need it here is a hand-drawn map of the important map through the maze.I’ve posted my map here. http://sites.google.com/site/fgrc64a/Home/pictures/MapofCave.jpg

Beginning Scratch 3

I used this project to show a young potential programmer how to use math equations in Scratch. Of course the equation in the program is wrong. We worked on fixing it and making other changes. I also tried to introduce the concept of variables to my six-year-old subject by creating a variable for Sissy’s age. The result? I was told that "I don’t want to do this anymore because it is using up my time to play Webkinz". Oh well, I tried.

Beginning Scratch 2

The move and say blocks are two of the most basic Scratch programming blocks. My actual intent with this program was to encourage my young programmer to explore the set of programming blocks and practice dragging them and snapping them together. A beginning programmer might need help with finding and using the next costume block. I had used costumes in my example but did not have the Scratch sprite explain how to make or use them. BTW, there are long pauses between the sentences. Much of our session was just spend doing fun things like exploring the different Motion and Look blocks. Because I had slyly introduced the topic of costumes, we also investigated the Scratch paint editor.

Beginning Scratch 1

I used this project to introduce Scratch programming to a certain young programmer who was six at the time. We also moved the circles to draw different shapes. I did it this way to avoid mentioning the coordinate system. We also explored different pen sizes and colors.

Christmas Jukebox

I’ve added three holiday snapshots and three two-part songs to Lanie’s remix of Paddle2see’s Christmas Jukebox. I also changed the music player sprite to work with my two-part music transcriber http://scratch.mit.edu/projects/digimath/339751 My two-part arrangement for "Away In A Manger" and "We Three Kings of Orient Are" are based on arrangements from a beginners piano book called Christmas Carols by Rachel Beatty Kahl. It would be wonderful if others would remix this and add a few of their own holiday snapshots. From the original project description: Plays Christmas Songs in a random order with random instruments. Will continue until you are very tired of them! Currently, there are 12 songs in it. Hold down the Space Bar to skip to the next song. Have fun and Happy Holidays!

Music_Transcriber_2_parts

I’ve modified Paddle2see’s Music Transcriber project by adding a feature to allow two notes to be played at the same time. After you enter a melody note you can add a secondary note by first clicking on the blue "Add Secondary Note" button and then clicking on the staff to add the note. When the program starts or after clicking the Green Flag, you can press the space bar to hear a sample two-part song. A melody note that has a secondary note is stored in the notes array as a negative value. I’ve modified the player script to test for this and, when true, play the melody node and the next note in the notes list at the same time. The following is from Paddle2see’s original project notes: Controls: ====== Up/Down Arrows: Set the Sharp/Flat/Natural Left/Rigth Arrows: Set the note duration Mouse Click on Staff to enter a note Play Button: Play back the music Rest Button: Insert a rest at the current note duration. Nothing is printed on the staff. Clear Button: Clear the staff so you can enter more notes. Delete Button: Delete the last note entered into the Notes list. Green Flag to delete the list of notes Once the list is populated with values, right-click on it and export the list. Then, drop the Music Player sprite onto the project and import the list of notes. Technical Notes: ============ The note durations are stored in the fractional portion of the list values. I have set it up as 32 is a whole note, 16 half note and so on. Once you have built a list of notes, right-click on the Notes list viewer and Export the list to a text file. Then, import it into a project that has the Music Player sprite.

Drive a Car!

Drive this car along the path using the path points 1 through 8. I modified AFawcett’s program by adding more levels and changing some of the logic. The instructions are included in the project (Help button). You won’t advance to the next level unless you complete the path while in the "keep to the path" mode. In the "keep to the path mode" the car does not always stop when it touches green. I think this is because I used the glide block and a technique to stop the car in mid-glide. If you switch to Random mode it will be more obvious where the car went into the green. There might still be some bugs. Let me know what you think and if you have problems. The original song that was used in this project was the Benny Hill theme song (Yakety Sax) which might be copyrighted. I have replaced that song with one that is covered under the Created Commons license.

The Princess and Frog

I liked the way kekkle’s Princess Beauty project was starting out so it inspired me to make it into a small game. When the Princess catches the frog, the frog turns into a … well, uhm, a handsome Prince?!?! The sound will be a little more interesting if you download and play it since the volume gets louder as the Princess gets closer to the frog. Did you catch the frog?

THE SEARCH - V1.1

I downloaded SuperZac’s game to make a small logic change. Level 2 will now start right after you complete level one. Also, to make things harder, level 2 does not reset the life meter. And I changed the music of level 2 to this Big Band song: "Mills Cavalcade Orchestra - Lovely Liza Lee 1935" Creative Commons license: Public Domain From the web site www.archive.org Level 1:You are a lost tire, seeking to find the car to which you belong... Level 2: You are a lost coin, looking for your piggy bank... Left ; Right arrows to move. Up arrow to jump. Don't touch red. Space to Start.

AFawcetts_Halloween_Competition

Since I can’t draw I remixed AFawcett’s competition project in a different way. I’ve changed the first screen and added some spooky sound effects. The spooky sounds come from Gurdonark Drone Sample Pack 1" by Gurdonark 2006 - Licensed under Creative Commons. Click on the background to continue to the next screen. Update November 1, 2008. I've added two drawings to this project.

Platform_(with_shadow_variable_displays)

This is Coolstuff's project. He says "See my other project without the variable displays. It's so much faster...". I have modified Coolstuff's project to use "shadow" variables that are only updated once per 0.25 seconds. From what I can tell, the IDE (offline) performance is about the same as the performance with no display of variables. This might be the same effect that Jens displays in his race project [url] <A href="/projects/Jens/170845[/url">(link to project)</A>]. The display for a variable is updated for every iteration. This does not seem to work online and will probably need to be downloaded to see the variables being updated.

Math Minute

The Math Minute. This creates a set of 30 addition equations which can be saved as a graphic file and then printed as a worksheet. The goal is to do them quickly, but, accuracy is a must. In one timed minute, write down as many sums as you can. Count how many you got right but stop after the first mistake. Complete the worksheet with no errors to become a member of the one-hundred club.

Seahorse_for_superzac

I added some animation and music to superzac's seahorse project. The music is "Looking Out Distractedly" by jaspertine 2008 - Licensed under Creative Commons Attribution Noncommercial (3.0) Updated 10/22/2008 The seahorse brightness modification was suggested by AFawcett.
