我正在一个类（路径）中创建一个 CGRect。我已经验证该类正在创建矩形。现在，我在类中构建了一个方法，理论上，当被问及触摸位置是否在矩形内时，它应该返回 true。问题是，它总是返回 false。我已经根据需要验证了该方法是否有效。相关代码如下：
路径.h
#import <Foundation/Foundation.h>
#import "cocos2d.h"
@interface Path : CCSprite {
CGPoint startP;
CGPoint endP;
CGRect pathRect;
CGPoint touchP;
}
-(id)initWithPoints:(CGPoint)sP :(CGPoint)eP;
-(bool)touchWithinBounds:(CGPoint)touch;
@property (nonatomic, assign) CGPoint startP;
@property (nonatomic, assign) CGPoint endP;
@property (nonatomic, assign) CGRect pathRect;
@end
路径.mm
#import "Path.h"
@implementation Path
@synthesize startP;
@synthesize endP;
@synthesize pathRect;
-(id) initWithPoints:(CGPoint)sP :(CGPoint)eP {
if ((self = [super init])) {
startP = sP;
endP = eP;
pathRect = CGRectMake(startP.x-2, endP.y, 5, 480);
}
return self;
}
-(bool)touchWithinBounds:(CGPoint)touch {
touchP = touch;
if(CGRectContainsPoint([self pathRect], touch)) {
return true;
} else {
return false;
}
}
-(void) draw {
glColor4f(1.0f,1.0f,1.0f,1.0f);
glLineWidth(5.0f);
ccDrawLine(startP, endP);
}
-(void) dealloc {
[super dealloc];
}
@end
在我的主游戏场景中，我初始化了一个路径并将其添加到一个可变数组中：
paths = [[NSMutableArray alloc] init];
Path *path1 = [[[Path alloc] initWithPoints:ccp(winSize.width/3, 0.0) :ccp(winSize.width/3, winSize.height)] autorelease];
[self addChild:path1 z:0];
[paths addObject:path1];
然后在 ccTouchesBegan 中，我将触摸位置发送到 touchWithinBounds。但是当矩形被触摸时，它不会报告 true，而是总是报告 false：
UITouch *touch = [[event allTouches] anyObject];
CGPoint location = [touch locationInView: [touch view]];
location = [[CCDirector sharedDirector] convertToGL: [touch locationInView:touch.view ]];
for (Path *path in paths) {
CCLOG(@"%d", [path touchWithinBounds:location]);
我在各个部分之间是否缺少某种联系，或者我是否误解了交互是如何一起工作的？
谢谢
