GO HERE FOR A MUCH BETTER VERSION: https://scratch.mit.edu/projects/980743149/ click see inside if you are interested in knowing how this works note that this has not been thoroughly tested and might not work on everyone's computer. this is a project capable of storing data on your computer through caching without cloud variables! to use, type in a key, only letters are allowed, if you type any characters such as a number, symbol or upper case letter then it will not work. next, duplicate the tab and type in the same key on the other window. now, on both windows, and not at the same time, click a to calibrate the engine for your computer. now comes the interesting part: press w to write a bit, type either 1 or 0, and on the other window if you press r to read the cache, then it will read the same 1 or 0! you can even reload the page and it will read the same bit, it will even work if you remix the project and use the remix as another tab! there are many possible uses for this, such as saving your game without the need for cloud variables, you could use it to stop people voting multiple times in a cloud voting project, or to store if they have seen the tutorial to a project before. note that the more that you use this system, the longer it will take to read and write data with a given key, so change key if it is taking too long. you must use the same key on both tabs also note that data cannot be stored for too long, or it erases.
massive credit to @Retr0id for the idea of using translate blocks to store data, this was inspired by this project: https://scratch.mit.edu/projects/678420788 however it may have been @TimeTravel2022 who did it first. I am not sure who actually invented it.
