I decided to make a compilation of different scratch features that I know of that aren't obvious. That's why I made this simple game. There's 8 levels, divided in different sections. If you know any other cool stuff I can add more levels. Try to beat it on your own, you can look at the code to help yourself, though it won't help you much. Levels 1-2: Mouse stuff Levels 3-4: Color stuff Levels 5-6: Sound Stuff Levels 6-8: External Stuff WARNING: Levels 6-8 require changing your devices settings, make sure to put them back to their original states after beating the level. If you don't know how to do this, don't change them. If you get stuck, here's a guide with explanations of how each works: Level 1: No sprite can touch your mouse when it's out of the project! Move your mouse out of the project and around the red wall, then just touch the star. Level 2: When your mouse is on a menu, it isn't in the project! Right click and move your mouse over the pop-up menu to the star. Make sure not to touch the red part when doing this. Level 3: In scratch, if you divide by 0 you get Infinity. Setting the color effect to this puts your sprite in gray scale. If you just type "Infinity" instead of putting ((1)/(0)), it still works! To beat this level, click CHANGE COLOR and type in "Infinity". NOTE: This is case sensitive, so "infinity" doesn't work. Level 4: Did you know scratch accepts hexadecimal color codes? These codes are the way most programs store color. They're formatted #RRGGBB (Red, Green, Blue) where each letter represents a number in base 16 (Instead of just 0 to 9, you've also got a, b, c, d, e, and f!). Scratch cats orange color is #ffab19, so by setting the wall to that color, you can pass through! Level 5: According to Oxford Dictionary, a pitch is "the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone", in other words the pitch is determined by the frequency of vibrations. The higher the pitch, the higher the frequency, and with higher frequencies come higher speeds. But this also works in reverse! If the pitch is very low, the frequencies are lower and the speed is too. To solve this you can set the pitch to a really low number... but do you know whats the lowest number scratch lets you pick? That's right, -Infinity! WARNING: From here on the levels require changing your devices settings, make sure you know what you're doing before continuing Level 6: When you play a sound in scratch, it sends it to your audio playback device which in turn plays the sound. The scratch block [play sound ( ) until down] waits until the playback device receives and plays the sound. If you have your volume at 0, your playback device receives the audio and plays it despite the fact you can't hear it. Now, what if you didn't have a playback device? Then scratch would just get stuck waiting for the non-existent device to receive the sound and wouldn't continue running the code. To beat this level you must not have an audio playback device. Luckily that doesn't mean to rip off your computers speakers! All you have to do is go to your sound settings, find the manage devices button, and disable all of them. After that just get to the star. NOTE: Make SURE you enable them again, otherwise not only scratch, but no apps or sites will play sound (not even system sounds). If you don't know how, just google "How to re-enable audio devices in [your operating system (Windows/Linux/Mac/etc)]" Level 7: This ones a lot simpler. Did you know scratch has an <online?> block that returns true or false depending on whether or not you have WiFi? I didn't, and I don't think I've ever seen someone use it in a project. Just disconnect from WiFi and you can get the star. NOTE: Make sure to get connected again so you can comment and stuff. If you don't know how, just google "How to connect to WiFi". Level 8: Scratch's (current [year/month/day/etc]) blocks use your computers date instead of checking online. That makes it susceptible to lying. Go into your computer settings and set your date to before 2010. NOTE: Make SURE to set it back to normal, because most websites don't work with your date set so far back. I learned this the hard way when, while making this, I changed it, and then I couldn't even google how to fix it. Credits: Obvious credit to scratch and the scratch team for making this possible. The scratch cat head comes from none other that the scratch cat sprite. The star comes from the wand sprite. The WiFi dinosaur is by John Google. The rest is drawn by me. The mouse part came when I was thinking of features and remembered The Impossible Quiz. The color stuff comes from comments I read years ago on the studio Dads & Mums on Scratch ( ) (you can probably pinpoint the when I saw the hex comment based on when I started using them in projects).
