No instructions need to be provided. This is an automatic project.
Credits to me for making the project. You might be thinking, what is this "event casting"? Well, this is a enhanced project where 2 events and 2 blocks are both connected together in 1 "when flag clicked" function. This is several blocks, variables & lists coming in and dropping off the events that need to be transferred to one another. When all blocks, variables & lists finally cast the "loop" event, all blocks, variables & lists associated with a function that recently had other functions/events added to it; by the other event, will rebroadcast a loop. Meaning that all functions, events, blocks, variables & lists will repeat the previous action(s) recently broadcasted, until the tempo in music reaches a desired variable number, 500.001. After this number is reached (which is extremely unlikely), the function(s) from the start will stop, causing the associated functions, events, blocks, variables & lists to all connect together; causing the project & interior projects to stop. I'm sorry if you didn't get specific parts of the explanation, or the entire explanation. I don't know any other ways to explain it.
