Overview

Moto Trial Racer XNA is a Nokia example application and a motorcycle racing game on Windows Phone 7 & XNA Game Studio 4.0, demonstrating especially the use of Box2D.XNA. This application has been ported from corresponding​Qt/QML example, and thereby also demonstrates and provides guidance on the porting and co-development between Qt and Windows Phone. Application concept and graphics are reused from QML version.

More information about the porting of the application can be found from the Porting Story page.

Instructions

Playing the game

A new game can be started by selecting New Game from the main menu and then the desired level from the shown list. After selecting the level the clock starts and the player can start driving the motorcycle. The goal is to get the motorcycle and the driver to the chequered flag as fast as possible. The game ends if any part of the motorcycle or player touches the spikes, or if the player's head touches any other object. If that happens, the same level can be tried again or another level can be selected. When the player gets to the chequered flag fast enough, he/she gets his/her name and time on the high scores list. The game can be paused, restarted, and exited at any time via the options menu.

The motorcycle is accelerated by tilting the device towards the player and braked by tilting the device away from the player. The center of mass can be moved backwards/forwards by pressing the arrow buttons in top corners of the game screen.

If you are running the game on emulator, you need to enable the keyboard by pressing PAGE UP key or PAUSE/BREAK key. When the keyboard is enabled the motorcycle can be accelerated by pressing the UP arrow key and braked by pressing the DOWN arrow key. In the level editor you can rotate an active object counterclockwise/clockwise by pressing 'A'/'D' key.

Creating own custom levels

The level editor can be launched from the main menu. In the level editor view new objects can be added by pressing the object buttons in top of the screen. After a new object is added, it can be dragged to any position. An active object can be also rotated by using two fingers. The starting point of the motorcycle can be adjusted by moving the motorcycle icon to the desired position. When the level is completed, it can be named and saved. The custom levels can be deleted by pressing and holding a level button in the level selecting view down for two seconds.
