Collision Detection: Creating SVG Polygons for the Game Actors and Writing Code to Detect Collision - Beginning Java 8 Games Development - page 521

There are one or two basic changes that we'll need to make in the InvinciBagel.java
class, before we switch over into the Bagel.java class to implement collision detection.
Since we are going to use the CastingDirector object in the collision code, we'll have
to remove the private access control keyword in the CastingDirector
castDirector; declaration, as shown in Figure 16-28 . We are trying to keep as
many of the variables in our InvinciBagel class private as possible, and later make
them package protected if we need to access them from another class, such as Ba-
gel.java.

tion
The next thing that we'll want to do is to remove the iBagel object from the .ad-
dCurrentCast() method call parameter list in the createCastingDirection() method. We
are doing this so that the InvinciBagel, who we are going to be checking for collision
against the rest of the Actor objects, which are contained in the CURRENT_CAST
List<Actor> object, does not check for collision against itself! The new shorter meth-
od call (minus the iBagel object) should look like the following Java code, which is
shown highlighted at the bottom of Figure 16-29 :
castDirector.addCurrentCast( iPR0, iPH0, iPV0, iPB0 );
