// more globals go here public GamePadBehavior(JOALSoundMan sm, String nm) { soundMan = sm; soundNm = nm; glove = new FPSGlove(); wakeUpCond = new WakeupOnElapsedTime(DELAY); } // end of GamePadBehavior() public void initialize() { wakeupOn(wakeUpCond); // more methods go here } // end of P5Behavior P5Behavior extends ViewPlatformBehavior so the scene graph s ViewPlatform s transform group, called targetTG, is available. P5Behavior adjusts the player s camera position by applying translations and rotations to targetTG. A reference to JOALSoundManager is required so the listener can be translated and rotated in unison with the camera. JOALSoundManager also switches the cow s music on and off, which requires its name, soundNm.

A first guess might be that this function is used to scan a segment of records from disk for a storage engine So, let s check out ha_rnd_init(), shown in Listing 4-23, which can be found in /sql/handlerh Why just the header file Well, the handler class is really just an interface for the storage engine s subclasses to implement We can see from the class definition that a skeleton method is defined..

Aligning the Atan2 angle with the angle system used by XNA // XNA puts 0 degrees upwards, whereas Atan2 returns it facing left, so add 90 // degrees to rotate the Atan2 value into alignment with XNA targetAngleDegrees += 90; // Atan2 returns values between -180 and +180, so having added 90 degrees we now // have a value in the range -90 to +270 In case we are less than zero, add // 360 to get an angle in the range 0 to 360 if (targetAngleDegrees < 0) targetAngleDegrees += 360; So do we now have an angle that we can turn to face Well, yes we do, but making the spaceship jump immediately toward the touch point feels very unnatural It is much nicer to get it to rotate toward the touch point, so let s transition from the current angle to the target angle.

Listing 4-23. /sql/handler.h handler::ha_rnd_init() int ha_rnd_init(bool scan) { DBUG_ENTER("ha_rnd_init"); DBUG_ASSERT(inited==NONE || (inited==RND && scan)); inited=RND; DBUG_RETURN(rnd_init(scan)); } Since we are querying on a MyISAM table, we ll look for the virtual method declaration for rnd_init() in the ha_myisam handler class, as shown in Listing 4-24. This can be found in the /sql/ha_myisam.cc file. Listing 4-24. /sql/ha_myisam.cc ha_myisam::rnd_init() int ha_myisam::rnd_init(bool scan) { if (scan) return mi_scan_init(file); // } Sure enough, as we suspected, the rnd_init method involves a scan of the table s records. We re sure you ve gotten tired of us saying this by now, but yes, the mi_scan_init() function is implemented in yet another file: /myisam/mi_scan.c, shown in Listing 4-25. Listing 4-25. /myisam/mi_scan.c mi_scan_init() int mi_scan_init(register MI_INFO *info) { info->nextpos=info->s->pack.header_length; /* Read first record */ // } Unbelievable all this work just to read in a record to a READ_RECORD struct! Fortunately, we re almost done. Listing 4-26 shows the rr_sequential() function of the record cache library. Listing 4-26. /sql/records.cc rr_sequential() static int rr_sequential(READ_RECORD *info) { while ((tmp=info->file->rnd_next(info->record))) { if (tmp == HA_ERR_END_OF_FILE) tmp= -1; } return tmp; }

When processStimulus() is triggered, it updates the glove s state with a call to FPSGlove.update(), then reads the current data to possibly translate and turn the camera and toggle the cow s music on and off: public void processStimulus(Enumeration criteria) { glove.update(); // update the glove settings // possibly translate, turn, and toggle the sound translate(); turn(); toggleSound(); wakeupOn(wakeUpCond); // make sure we are notified again } // end of processStimulus() The next scene graph frame is rendered only when processStimulus() has finished, so all the camera changes will appear in the scene at the same time.

To do this we will simply check to see whether the target angle is less than or greater than the current sprite angle If they are not equal, we will move the sprite angle toward the target angle until they meet, at which point we have finished rotating There is a final complication here, however If the current spaceship angle is at 350 degrees, and the calculated target angle is at 10 degrees, the approach that we have just discussed will cause the spaceship to rotate all the way around through 340 degrees in a counterclockwise direction, whereas it would be much more efficient for it to rotate just 20 degrees clockwise This is illustrated in Figure 4 10 In practice, having the ship rotate like this is very jarring and will be very frustrating for the player who asked for only a minor rotation!.
