Game Development Reference
In-Depth Information
on the screen. In this section, we will look at how
Actor
is implemented, followed by some concrete
examples. Let's start by taking a look at the header file of the
Actor
class, shown in Listing 6-9.
Listing 6-9. Actor.h
#import <Foundation/Foundation.h>
@class GameController, Actor;
@protocol Representation
-(UIView*)getViewForActor:(Actor*)anActor In:(GameController*)aController;
-(void)updateView:(UIView*)aView ForActor:(Actor*)anActor In:(GameController*)aController;
@end
@protocol Behavior
-(void)applyToActor:(Actor*)anActor In:(GameController*)gameController;
@end
long nextId;
@interface Actor : NSObject {
}
//State
@property (nonatomic, strong) NSNumber* actorId;
@property (nonatomic) BOOL added;
@property (nonatomic) BOOL removed;
//Geometry
@property (nonatomic) CGPoint center;
@property (nonatomic) float rotation;
@property (nonatomic) float speed;
@property (nonatomic) float radius;
//Behavoir

//Representation
