I was looking at Fbrd's 'Curve Art 3' project (an amazing project!) and I started playing around with connected dots. Then, I made them act like a series of masses connected by springs and started getting some cool vibrational behavior. So I sort of threw this project together to let people play with vibrations. It has a bunch of setups controlled by the "Change Setup button at the bottom of the screen. Here are the setups: Jump Rope Setup: Your mouse is holding the right end of the chain, the left end is fixed. Try shaking the rope at different speeds and directions and see what shapes you can make. By shaking it slowly, you should be able to get all the dots going up and down at the same time, that is the First Vibrational Mode. Shaking at a rate about twice as fast, you should be able to get the right half dots going up while the left half is going down; that is the Second Vibrational Mode. Maybe you can find others! Pluck Setup: The chain is fixed at both ends. Use your mouse to pluck on the dots and watch the chain respond. You could use this mode to roughly estimate the base natural frequency, if you counted vibration cycles in a given period of time. Forced Excitation Setup: This is the most compllicated setup by FAR! Here, you control the rate at which the right end of the chain is shaken. The size of the shake is always the same but the response of the chain will vary depending on how fast it is shaken. By searching around, you should be able to find the Resonant Frequencies; these are the ones that cause the chain to vibrate the most. You can use the mouse buttons (+ and -) to move the shaker frequency or use the Left/Right arrows. I have built in plotting capability (controlled by the Plotting On/Off button) so you can plot Peak Amplitude (how high it shakes) against shaker Excitation Frequency (how fast it is shaken). Use the Reset Peak Amp. button to reset the Peak Amplitude to zero before each reading. Then, use the Plot Point button to record a reading, when you feel the system has reached a steady state. Note that the Peak Amplitude can also be reset with the Down Arrow key and the Plot Point function can be done with the Up Arrow. Finally, the Excitation Frequency can also be set by clicking on the Graph, if you have plotting turned on. Controls Summary: Left/Right - Shaker Frequency Down - Reset Peak Amplitude Up - Plot point Space - Next Setup http://scratch.mit.edu/static/projects/Paddle2See/163487_sm.png http://scratch.mit.edu/projects/bigB/157218 Play as Bulgaria in the Quidditch World Cup. Compete against teams from across the world for the Ultimate Prize. Use the arrow keys to fly and space to throw. You need 150points to win each round. Scoring gets you 10points and the snitch gets you 50. Goodluck http://scratch.mit.edu/static/projects/bigB/157218_sm.png http://scratch.mit.edu/projects/AddZero/152472 Remix me! Make your own lathed 3d shapes! Download to edit save and share. Just move the black dots in "edit mode" When you want to see it in 3d, change it to "View Mode" Try making Cups, Classes, Bowls, CD's, Tops, Lamp Shades, Tires... Anything symmetrical! Feel free to save and share your work! Download and edit in scratch. I'll add it to the Lathed 3d shapes gallery. HOW IT WORKS: When you enter "edit mode" every dot moves to it's x, y location and becomes visible, and it's drag-able so you can move it around. When you enter "view mode" every dot becomes invisible, and copies it's sprite location to it's x, y. Now it sets the DrawRotY to 0 and increments it based on the "DrawSteps" setting. for each of those increments, every dot's x,y location is rotated twice: First to the "DrawRotY", then to the "CamRotX", then the point is moved back from the camera "CamZ". After all the points are moved to where they go for that step, the "draw" sprite, with the pen down moves to all the points 01 through 16. Also all those points have the pen down so they draw the horizontal lines as they're rotating along the "DrawRotY". Let me know if you have more questions. UPDATED: Now with color picker. http://scratch.mit.edu/projects/AddZero/153575 Drawing now resets when sliders change. KNOWN ISSUES: It makes stray lines sometimes when changing values or switching to view mode. Please "love it" if you do! http://scratch.mit.edu/static/projects/AddZero/152472_sm.png http://scratch.mit.edu/projects/Colkadome/151510 Escape from the jail cell in this point-and-click adventure. Only the intro has a slow frame-rate so be patient... If you download it then the intro should work much faster (remember to play in presentation mode). ============= SPOILER ALERT ============= If you are stuck, refer to this walkthrough: Light Bulb: Screw into light on ceiling and flick the switch underneath to shine the code to the toilet onto the wall. Note: Slip it under the door. Nail: Once the note is under the door, use it to push the screwdriver out of the lock and onto the note. Screwdriver: Once on the note, collect the note with the screwdriver ontop. Use the screwdriver to open the vent. Acid: Zoom in on the toilet and pour it into the toilet bowl. Key: There is no point in saying what to do with the key. http://scratch.mit.edu/static/projects/Colkadome/151510_sm.png http://scratch.mit.edu/projects/axu/28142 One-Player game. This has AI enemy Arrows to move, SPACE to shoot (mouse to aim). !!NEW!! You can now set the lives and amount of creating land! If your hidden enemy is one of 8 adjacent squares then they'll be visible Legend: In bush and water other player can't see you. On sand you'll be slow On grass you leave track You can't go trough trees, but you can explode them http://scratch.mit.edu/static/projects/axu/28142_sm.png http://scratch.mit.edu/projects/JSO/15845 This is a basic platform game. It's a simple idea, get the basketball into the ring. But, in fact the ball makes a travel... Sometimes you will get some pseudo-3D levels. There are in-game instructions. Have fun! (maybe for a minute?) http://scratch.mit.edu/static/projects/JSO/15845_sm.png http://scratch.mit.edu/projects/goch/142552 Guess ten words by typing the letters with your keyboard! Wait until all the white rectangles are shown. You know all the words from Scratch. If a letter is wrong, an orange will disappear. http://scratch.mit.edu/static/projects/goch/142552_sm.png http://scratch.mit.edu/projects/dmagee/5670 This is a take on the classic asteroids game, but with many changes. The sound track is from bionic commando from the NES. The graphics come from random free sources on the internet. Gameplay: Use the arrow keys to turn and up and down to fire rockets to speed up and slow down. Press the space bar to fire. There are 3 powerups, Health (gears) gives you 10 extra health, shield gives you a 2 hit shield (saves you from 2 hits), this can be stacked for a total of 4 hits of protection. And the superman logo, which gives you 10 seconds of super powers (you can not die, and you can ram asteroids). You have 100 health, with no max health, each hit takes away your health (big = 50, Medium = 30 or 40, and small = 20) See how far you can get, and good luck. http://scratch.mit.edu/static/projects/dmagee/5670_sm.png http://scratch.mit.edu/projects/the_guardian/142104 This is based on bigb's Block Buster game. I remixed it to speed up the block detection routine. I also aded some additional levels and features. Hope you enjoy it. http://scratch.mit.edu/static/projects/the_guardian/142104_sm.png http://scratch.mit.edu/projects/am-barry/7998 Note ... some sounds are a bit loud, so very young children probably ought to play something else! I developed this as an example for pre-1st year undergrad students of what can be done with Scratch. It took me 3 hours total to complete the first version, and another 2 hours to enhance it to add better progression of difficulty, a spy plane, a bomber, and fix some coding problems. It is a version of the popular 1980's Atari Missile Command game, with most of the key features present. It starts slowly with only a small number of slow moving incoming missiles, but things hot up as you progress. You move the crosshair with the mouse and fire a defence missile using the mouse button. You have limited defence missiles in each city, which you must defend, and the number of remaining incoming missiles is displayed. You score more for missiles hit higher in the air. You will gain an extra city for each 10000 points you accumulate, but the missiles come in faster and more come at once the further you go in the game. You will also see a spy plane fly over at high altitude after you have reached 5000 points and a bomber come across at low altitude after 15000 points. The bomb drops by 'gravity', so get it early before it speeds up too much! I have got to 49590 so far (but it took me a lot of goes!)... Have fun! http://scratch.mit.edu/static/projects/am-barry/7998_sm.png http://scratch.mit.edu/projects/fullmoon/125755 Sea lions play volleyball! This game was my brother's idea, but I wrote the entire thing. He was my beta tester, though. Be sure to adjust the settings before you play. http://scratch.mit.edu/static/projects/fullmoon/125755_sm.png http://scratch.mit.edu/projects/blob8108/125971 Fly your plane through a 3D tunnel in space, avoiding obstacles by flying through holes in walls! CONTROLS: use the arrow keys to move, and press space to do a roll (this doesn't do anything at the moment, I just put it in for fun.) I was trying to make a 3D game, and this is what I came up with. It's occasionally a bit slow because Scratch is slow, but for me it ran perfectly in presentation mode in Scratch and on the website. I made a NEW VERSION! Check it out at http://scratch.mit.edu/projects/blob8108/157221 , with a new level, mouse contol, the plane's shadow added, and cool music! http://scratch.mit.edu/static/projects/blob8108/125971_sm.png http://scratch.mit.edu/projects/the_guardian/130518 Help the spider avoid the bubbles, or shoot them. If he gets caught with no webs, the game is over. Use the arrow keys to move and space bar to shoot. M - turns off the music. P - pauses the game. http://scratch.mit.edu/static/projects/the_guardian/130518_sm.png http://scratch.mit.edu/projects/BATzerk/57705 Corrected shadows' range on screen, made the balls 'throwable', and reduced blockiness of balls. Now with optional elastic band. Also, toggle the band with "B". "C" for clear. Spacebar to cycle through 3 backgrounds. Up arrow key to thrust balls away from you. Enjoy!! =] http://scratch.mit.edu/static/projects/BATzerk/57705_sm.png http://scratch.mit.edu/projects/Jens/98418 this project attempts to let a sprite bounce off irregular surfaces. What makes this project special is that the bouncer can rotate around its center, and also around each sensor, simply using copies of the same costume with the rotation axis set to different positions each, thereby enabling it to measure the wall's slope at any point. If it gets stuck somewhere press the green flag to reset it. For some reason it currently does *not* work correctly online all the time. It's supposed to rotate until both sensors touch the surface in order to measure the surface's slope. If it doesn't do that online, you may need to download it.
