Check my scratch profile for an updated version. Welcome to my engine simulator. This is a very barebones engine simulator so please keep that in mind. Also keep in mind scratch's framerate cap hinders the true capability of this simulator. For that reason, I would suggest playing this project on turbowarp. It has more or less been developed for turbowarp. CONTROLS--- A: Enable/Disable Ignition S: Starter motor
Unfortunately right now you need to use the blocks in "see inside" to be able to use different engines. An update has been made to make firing more accurate by using a bit more of a strenuous check.
