CHAPTER 2
The Preferences panel includes controls for defi ning Player behaviors.
You can enable Collisions and Gravity and set values for Acceleration and Maximum Velocity under the Navigation
heading. These options work the same as their respective toolbar buttons.
The Acceleration value determines how quickly your avatar begins to move. A low Acceleration value will cause your
avatar to start moving slowly and pick up speed the longer the arrow key is held down. A high Acceleration value will
cause the avatar to move with Maximum Velocity as soon as one of the arrow keys is pressed.
i
The Acceleration and Maximum Velocity values are only used when navigating with the keyboard.
The Maximum Velocity value is the fastest speed that the avatar will move, regardless of how long the arrow key is
held down. Both Acceleration and Maximum Velocity can range from 1 to 100.
Don't be tempted to set the Acceleration and Maximum Velocity to their maximum value. Unless you are navigating
a very large environment, maximizing these values will make the avatar motion diffi cult to manage.
Display Preferences
The Display tab of the Preferences palette lists and lets you choose your Preferred Renderer. Options include
Hardware (Direct3D) and Software. If your computer system has a video card that supports hardware rendering,
then you will see better performance and image quality by selecting the Hardware (Direct3D) option as the Preferred
Renderer. Software rendering, although slower, will always work regardless of your system.
i
Even if you select the Hardware (Direct3D) option, hardware rendering may be unavailable if Atmosphere is unable
to recognize your video card. Appendix A, "Installing and Confi guring Atmosphere," includes information on
confi guring Atmosphere to recognize your video card as well as a list of supported video cards.
