Some of us know what the “wait until Unix timestamp) block is (I actually don’t have it lol, but I think I know how it works). But I found a way to recreate it using the Time variable (only visible in beta editor). So how I did it, I first put a “when game starts” block, with what happens before the timestamp block. Then, where you would place the hidden block, make a variable, and set it the the Unix timestamp you want it to wait for (use https ://epochconverter.com). After that, place a “repeat forever” block, and inside that, place a “check once if” block. For the condition, use (Time > (your variable that you made)). Inside that, use the broadcast message block with something you can remember. After the broadcast message block, put a repeat forever block so it doesn’t continuously broadcast the message. Then, put a “when I get message” magenta block with the message you broadcasted, and inside that, put what you would put after the wait until Unix timestamp block.
Sorry if this was a bit long, but if you skimmed through it, here’s a link to a project I made with this:
