Final Project - Winter

Completed 12/11/2003.

Project Overview

This program is an interactive outdoor winter scene.

Interaction

There are two main modes of interaction -- on foot and on a sled.

To detect mouse motion, the cursor is locked inside the window. To free the cursor, press the escape key. To regain focus, click inside the window.

• Common Controls
  • Keyboard
    • a/s/d/w = Move left/back/right/forward.
    • q/e = Turn left/right.
    • o = Get into or out of the sled.
    • x = Exit.
    • escape = Free the cursor.
  • Mouse
    • Left click = Throw a snowball, or just regain focus if the cursor was freed.
    • Middle click Get into or out of the sled.
  • On Foot
    • Mouse
      • Motion = Look around or turn.
      • Right click = Jump.
  • On Sled
    • Mouse
      • Right button (hold it) = Let go and let gravity move the sled.
    • Keyboard
      • Space (hold it) = Let go and let gravity move the sled.
