The reason is that we can actually end up rotating outside of this range, as you will see shortly Once this has been established, the sprite angle is converted into degrees Personally I find working in radians quite uncomfortable and I much prefer degrees, so this makes the code much easier to understand There is, of course, a small performance hit for performing this conversion, so if you can work in radians (or convert your code back to using radians once you have it working), it will run a little faster as a result Now for the trigonometry XNA provides a Math class function called Atan2, which returns the angle through which we need to rotate from 0 radians in order to face the specified point exactly what we.

Figure 14-11. Class diagrams for HandView3D HandView3D creates a JFrame holding a WrapHandView3D JPanel where the scene is rendered. HandView3D andWrapHandView3D are very similar to the ObjView3D and WrapObjView3D classes in 7. The ModelLoader, CheckFloor, and ColouredTiles classes are unchanged. JOALSoundMan (from 13) manages the 3D sound; FPSGlove is from the previous section. All that s really new is P5Behavior and several methods in WrapHandView3D that create the behavior, utilize JOALSoundMan, and close down the glove and sound production at termination time. I ll describe those in detail now.

But first, the join_init_read_record() function, shown in Listing 4-21, is our link (finally!) to the storage engine abstraction subsystem The function initializes the records available in the JOIN_TAB structure and populates the read_record member variable with a READ_RECORD object Doesn t look like much when we look at the implementation of join_init_read_ records(), does it Listing 4-21 /sql/sql_selectcc join_init_read_record() static int join_init_read_record(JOIN_TAB *tab) { init_read_record(&tab->read_record, tab->join->thd, tab->table, tab->select,1,1); return (*tab->read_recordread_record)(&tab->read_record); } It seems that this simply calls the init_read_record() function, and then returns the record number read into the read_record member variable of tab That s exactly what it is doing, so where do the storage engines and the record cache come into play We thought you would never ask Take a look at init_read_record() in Listing 4-22 It is found in /sql/recordscc (sound familiar ) Listing 4-22 /sql/records.

need Because we are now storing the touch point in object space, we can simply find the angle needed to face the point and we are there well, nearly, anyway To keep things using the same measurements, we convert the return value from Atan2 into degrees The code is shown in Listing 4 32 Listing 4 32 Finding the angle required to face the touch point // Ensure that the current angle is between 0 and 2 PI while (Angle < 0) { Angle += MathHelperTwoPi; } while (Angle > MathHelperTwoPi) { Angle -= MathHelperTwoPi; } // Get the current angle in degrees float angleDegrees; angleDegrees = MathHelperToDegrees(Angle); // Calculate the angle between the ship and the touch point, convert to degrees float targetAngleDegrees; targetAngleDegrees = MathHelperToDegrees((float)MathAtan2(pointY, pointX)); We have a little more work to do, however.

P5Behavior is a class implementing a time-driven Java3D behavior triggered every DELAY ms: public class P5Behavior extends ViewPlatformBehavior { private static final int DELAY = 75; // ms (polling interval) // more constants go here private WakeupCondition wakeUpCond; private FPSGlove glove; // sound-related private JOALSoundMan soundMan; private String soundNm; // name of the JOAL source

cc init_read_record () void init_read_record(READ_RECORD *info,THD *thd, TABLE *table, SQL_SELECT *select, int use_record_cache, bool print_error) { info->read_record=rr_sequential; table->file->ha_rnd_init(1); } Two important things are happening here First, the info pointer to a READ_RECORD variable (passed in the arguments of init_read_records()) has had its read_record member variable changed to rr_sequential rr_sequential is a function pointer, and setting this means that subsequent calls to info->read_record() will be translated into rr_sequential(READ_RECORD *info), which uses the record cache to retrieve data We ll look at that function in a second For now, just remember that all those calls to read_record() in the while loop of Listing 4-21 will hit the record cache from now on First, however, notice the call to ha_rnd_init() Whenever you see ha_ in front of a function, you know immediately that you re dealing with a table handler method (a storage engine function).

XNA considers 0 degrees to point straight upward, and we generally expect it to range from 0 to 360 degrees Atan2 returns an angle in the range of -180 to 180 degrees, however, with 0 degrees pointing to the left instead of up To map this angle into the same space that XNA uses, we can first add 90 to the angle we have calculated This puts the 0 degree angle pointing up again, and results in a range of -90 to 270 degrees To get back to the positive degree range, we check to see whether the value is less than 0, and add 360 if it is This finally results in an XNA-aligned angle in the range of 0 to 360 Listing 4 33 contains the calculations for this Listing 4 33.
