It is distributed as a ready-to-run html page and requires only a browser with JavaScript support. The Pirate Ship JavaScript Model was developed using the Easy Java Simulations (EjsS) version 5. Note that torque can not be applied if the simulation is paused or has not been started. Collect gold coins to return your treasure back. Jump over obstacles and cannonballs, play this interesting platform game on pirate ship and many enemies. When drive button is pressed, it turns green and a constant torque is exerted on the ship until the button is released or until the ship moves out of contact with the drive roller. Pirate Jacks ship is invaded by pirates and you need to reach his precious chest and become. The drive buttons are grey when no drive is available (simulation is paused or the ship does not contact the drive roller), the turn white when the drive is available. Because the drive can only push the ship when it is in contact, the drive is only available when the ship is within 30ยบ of its lowest position. The operator presses either the clockwise torque button or the counter clockwise torque button to change the motion of the ship. The ship swings freely from the pivot, and is driven by a roller built into the floor directly below the ship. The "ship" part of the ride has a center of mass that lies 14 m from the pivot point (approximately the center of the boat). These simulations were inspired by the Pirate Ride at Hershey Park. The Pirate Ship JavaScript Model is a JavaScript implementation of the Java version of the same model.
