Choose a stopping rule
1 · Learn
A count-controlled repeat ends after its specified number of repetitions. A forever loop continues until the program is stopped or another control ends it.
Choose according to the purpose. A short three-beat introduction needs a known ending. An animation that should keep moving while a project runs may use a continuing loop, but users still need a clear stop control.
2 · Worked example
I use repeat 3 for a three-ring signal. Forever would keep ringing, which does not match the plan and could be annoying.
3 · Your turn
Which loop better fits flashing an on-screen shape exactly six times: repeat 6 or forever?
Check your answer
Repeat 6, with a clearly defined flash sequence inside it.
4 · Apply your learning
Compare count-controlled and continuing loops in an approved tool using gentle movement rather than rapid flashing or loud repeated sound.
