CTools provides extra information about the performance of the project that can be extremely useful to developers. Importing CTools is fairly easy. - Put the CTools sprite in the backpack - Enter the project you want to use CTools in - Open the backpack and click and drag the CTools sprite into your sprite list. CTools provides the following: - Current framerate of the project(Scratch targets 30 and usually ends up with 31) - Whether turbo mode is enabled(causing framerates way above 31) - If the computer running the project is underperforming(framerate lower than 30 causing the project to run slower than normal) - Detection of pressing the stop button(or using stop all block, useful for thumbnails and other things) - Wait for certain amount of ticks.(frames, but will always run as if project is at 30fps)
