To enter this contest, Download this project, then adjust the sliders to get colorful patterns that you think are cool. TRY the sliders now to see how easy it is. Clear screen with space bar. Hide sliders with "H" key. Bring slider back with "Z" key. When you have something that looks fun, edit the scripts to adjust the starting values for those slider variables (they are easy to find and at the top of the script). After changing the variable starting values, share your project back online, then add it to the contest gallery at http://scratch.mit.edu/galleries/view/160055 Hints : Some people are replacing some of my costumes with some of their own, and the new patterns are awesome! Pick your costumes as there are many different colorful ones. At the very top of Sprite 3 and Sprite 13 you can pick each one of the starting costumes. If you want to change costumes on the fly while using the sliders during your testing, slide costumeLockOn to zero and mouse clicks will cycle through the costumes. Slide costumeLockOn back to zero when you have a cool costume, or go set the desired costume in the script. If you want to use size modulation, change growSpeed to a non zero number, then the min size and max size sliders will come into play. If you set min size to a small negative number such as -30 that will cause some pulsing of the patterns. When you have found all the cool values of the sliders that you want to save, edit Sprite 3 and save your values. It's a good idea to edit Sprite 3 in order to hide all of the sliders before you share this back online. At the top of the script there is a second when green flag clicked that currently shows the slider variables to the screen. I left in some hide variable commands just below there that are not attached. Just slide the hide variable block up and snap it onto the bottom of the second when green flag clicked and when you share your project no one will see the sliders. You can also edit the Stage to change the starting background color. That contol is the first thing in the script. Before sharing it back online, hit the green flag to make sure it does what you want. Message me if you have any questions or problems. Below are project notes from the original project http://scratch.mit.edu/projects/MikeKucinski/2437192. Most everything noted below still applies. ADDED COOL NEW FEATURES!!! Pressing the "2" key turns on automatic size modulation. Pressing the "3" key turns it off. It's a cool effect. Pressing the "4" key locks the current costumes so they can't change. Pressing "5" unlocks the costumes so they can change when you mouse click or press "M" or U". Press "6" key to freeze colors at current colors. Press "7" key to unfreeze colors so the colors of the costumes and background can flow. TRY THESE CONTROL ADJUSTMENTS : IT IS SO FUN!! Press the "9" key, then the "Q" key, then the "K" key and then the "4" key and you are in full control but the screen is very busy with sliders. Don't forget to press "W" to resume randomizing after done with sliders. Press space bar to clear screen if desired. Press "5" key to unlock costumes when done. "H" key will hide all of the sliders when you are done. Makes a great FREE gift or TOY!!! Give it to a brother, sister, friend, etc. You can email the link as the gift! Even toddlers will love the controls if you teach them how to operate a few of them. Press "R" to randomize now, or wait and randomizing will happen based on the slider value. Press R a few dozen times now to see what kind of cool patterns you can expect. Then read the rest of the project notes. Press "M" to sync both drawing costumes to same pattern. Press "H" key to hide the sliders. Space bar clears screen. Press "V" key and the patterns follow the mouse pointer. Press "A" key and the patterns are random and don't follow the mouse. Click mouse down to change drawing costumes but keep current random overall pattern. Use PatternChangeRate slider to lengthen/decrease randomize times or use up arrow to lengthen randomize time or down arrow to decrease randomize time. Type "B" to change the background color. I added a size modulation control. Type "Z or O or K or L or P" keys to use it. Slide growSpeed control to zero to stop size modulation effects or press "Y" key. If you find a random pattern you like and don't want it to change, type "Q" to stop the Randomizing. Type "W" when you want Randominzing to begin again. Mouse clicks still work while the Randomizer is off so you can cycle the costumes. Running growSpeed slider to zero and back will de"sync" patterns for a cool effect. Pressing "U" key will also unsync the drawing patterns too. Press "M" key to resync, if desired. Small values are best for PatternChangeRate slider. A value of 10 will change patterns every 35 seconds. A value of 100 will change patterns every 350 seconds. "S" key stops the current drawing so you can change to next costume without clearing screen. Or while stopped you can do a screen capture or a snippet. After hiting "S" key, click mouse to change costume. If you downloaded this project, you can see which costume is selected to draw next, but online, you can't see which is next. "C" key continues drawing operations. "X" key stops all. To insert your own costumes, follow below instructions. If you have any questions, message me. First note the script/code is different for my two sprites, but the costumes are the same between both sprites. I made the costumes the same by duplicating the first sprite, then modifying the code for the second sprite. To use your own costumes, download this project. Then the first thing to do is replace all of the costumes of Sprite 3 with the costumes that you want to use. After you are done adding ALL of your costumes that you want to use, then duplicate Sprite 3. In the duplicate that you made, delete all of the script/code so you can cut and paste the unique code from my second sprite into your duplicate. After you paste all of the code from my second sprite into your duplicate sprite (which has all of your own costumes), then delete my original second sprite since it has all my old costumes in it, and it doesn't have your new costumes. Adjust the initial "switch to costume selection" to the same costume in each of your sprites to "sync" the first costume used by each of the sprites. If you do this successfully, please message me with a link to your project online so I can check it out. Try holding the "U" key down for awhile. Also, it is fun to note the spaces not filled for some patterns. It's often symmetrical with a little fuzziness due to costume shapes. New features : P key decreases min size when grow Speed is modulated. L key increases min size when grow Speed is modulated. K key increases max size when grow Speed is modulated. O key decreases max size when grow Speed is modulated. The K and P keys allow extended range of max and min size beyone what the sliders allow. Pressing the "9" key shows some of the master sliders that are fun to control too. Suggest that you pause the randomizer at the same time by pressing the "Q" key too. When done playing with the sliders press "H" key to hide all sliders. To allow the background color to flow slowly through it's color range, hold the "F" key down for 2 seconds. To freeze the background color, hold the "I" key down for 2 seconds.
