What is repeat until loop in Scratch?
The “repeat until” block is a combination of a loop and a condition. It will run over and over until some question is answered as “yes”, or becomes true.
What is the difference between wait until and repeat until?
while loops continue on as long as their condition is met. Since wait() always exists, then that condition is met and is true. Therefore the script will loop until that statement is false.
What is the difference between repeat and repeat until block?
Explanation: The program repeats the blocks inside the loop. means if the block is true,the program skips the blocks inside the loop and moves on to the next statement in the program. But repeat until block is a loop. that means if the program false then again repeat the blocks inside the loop.
What is the difference between the repeat and the forever loop in Scratch?
The Repeat X times block repeats one or more block for a given number of times in a loop. Add a parameter as a number to determine the number of times the loop should be repeated. Attach one or more block in a loop to repeat. Forever block repeats one or more blocks in a loop forever means the loop will never stop.
Under which block palette does the repeat until block come?
Answer. Answer: In scratch programming under: Control palette.
What’s the difference between broadcast and broadcast and wait?
Just “broadcast” makes it broadcast the message then move on to the next block while “broadcast and wait” makes it broadcast the message, wait until it’s complete and then move on to the next block.
What does broadcast block do in scratch?
Broadcasting blocks are used to set the timing of events in an animated scene, game, or story.
Why would you use a repeat until loop?
REPEAT… UNIL loops are used to repetitively execute a subject statement until a condition is true. The condition is checked after the subject statement is executed.
Is Repeat until do while?

How to repeat a block with a break condition?
By adding an incremeting loop counter variable in the loop you can use a “repeat until” to replicate the function of a “repeat n times” block By using a “repeat until” block with only your break condition you get the equivalent of a “forever” block
What is repeat until in C Block?
Repeat Until () (block) – Scratch Wiki Repeat Until () (block) The Repeat Until () block is a Control block and a C block. Blocks held inside this block will loop until the specified boolean statement is true, in which case the code beneath the block (if any) will execute.
Is there a way to repeat a value inside of script?
The first and most simple one follows this: But this isn’t technically part of the script – it’s just repeating until some value returns true. In order to do it inside of the script, you’ll need to use a sneaky little trick with custom blocks.
How to break out of a script when it is running?
Create a custom block called whatever you want – but probably along the lines of “breakable loop”. Inside of it, create this script: By using stop script we are breaking out of the script that is currently running – which, according to Scratch, is the custom block. You could also use a broadcast-and-wait method, very similar to above:
