Detecting Turbo Mode can be done with a simple script:
when green flag clicked reset timer repeat (10) switch backdrop to (please wait v) end if <(timer) > [0.1]> then switch backdrop to (please use turbo mode v) ... end switch backdrop to (Turbo mode detected! v) ...
In turbo mode, the action of switching to the same background 10 times will take less than 0.1 seconds, but off it will take longer. If turbo mode is not on, the project will stop.
when gf clicked set [Counter v] to (0) reset timer repeat until <(timer) > [1]> change [Counter v] by (1) end if <(Counter) > [100]> then switch backdrop to (Turbo Mode detected! v)//or your Turbo Mode code. else switch backdrop to (Normal Mode v)//or your Normal Mode code. End
This script is a little different. Turbo speed will greatly speed up the repeat until C Block and the counter variable value will be very high.
Single Stepping
This article or section documents something not included in the current version of Scratch (3.0). It is only useful from a historical perspective. |
In Scratch 1.4, single stepping could be detected with the following script:
when green flag clicked reset timer switch backdrop to [Please wait v] // This block is required! if <(timer) > [0.1]> then switch backdrop to [Single stepping detected v] else switch backdrop to [Single stepping off v] end
The "switch to background" block can also be replaced with other blocks, such as "wait (0) seconds" if desired. Its purpose is to delay the script. If a script is single stepping, that block will take over 0.1 seconds to run, thus entering the "if" block.
