<h4 class="subsubsection"> 4.2.4.3 Constants </h4>
<p>There are several constants that we use in this game. By using constants it
is easier to change the behaviour. Even better would be to read these fields
from a configuration file but that is beyond the scope of this tutorial:
</p>
<table><tr><td> </td><td><pre class="example">// World defines.
#define ROOM_DIMENSION 10.0
#define MAZE_DIMENSION 3
// Adversary defines.
#define ADVERSARY_DIMENSION 1
#define ADVERSARY_MOVETIME 1.0
// Explosion defines.
#define EXPLOSION_EMITTIME 2000
#define EXPLOSION_PARTTIMELOW 500
#define EXPLOSION_PARTTIMEHIGH 600
#define EXPLOSION_TIME (EXPLOSION_EMITTIME+EXPLOSION_PARTTIMEHIGH)
// Laserbeam defines.
#define LASER_WIDTH 0.05f
#define LASER_LENGTH 100.0f
#define LASER_LIFETIME 300 // Milliseconds the laser will be visible.
#define LASER_FLICKTIME 20
#define LASER_OFFSET csVector3(0,-.5f,0)
// Movement defines.
#define MOVE_DISTANCE 5.0 // In one keypress we will move this far.
#define STEP_DISTANCE 1.0 // Step size for collision detection along path.
#define MOVECAMERA_SPEED 5.0 // Speed with which we move the camera.
#define ROTATE_ANGLE 0.5 // How much we want to rotate in one keypress.
#define ROTATECAMERA_SPEED 3.0 // Speed to rotate with.
#define PLAYER_SIZE 2.0
// These numbers define the position of the specific portal
// for the CreateRoom() function.
#define PORTAL_UP 0
#define PORTAL_DOWN 1
#define PORTAL_LEFT 2
#define PORTAL_RIGHT 3
#define PORTAL_FRONT 4
