1.2 “When stop sign clicked” hat block
Some users want a block (…) allowing users to click the stop sign to run a script. However, the stop sign is designed to stop all the scripts in the project. With this block in place, more scripts will start when you want the project to stop, thus defeating the purpose of the stop sign. This could also be rather confusing for the “stop all” block. Regardless, there is a workaround that uses the “when (timer) > (number)” hat block.
