Question

[解决]

我从cocos2d + chipmunk模板中复制了chipmunk文件夹结构并构建好。

'src'文件夹的Classes / Chipmunk / include / src
'include'文件夹的Classes / Chipmunk / chipmunk

感谢Beta尝试提供帮助。

我下载了花栗鼠5.3.1并尝试了一个简单的例子但我收到了这个编译错误：

我不确定是否正确添加了Chipmunk库，来自chipmunk .tgz的来源是什么？

以下是代码：

ChipmunkTestViewController.h

#import <UIKit/UIKit.h>
#import "chipmunk.h"


@interface ChipmunkTestViewController : UIViewController {
    UIImageView *barra;
    UIImageView *esfera;

    cpSpace *space;
}

- (void) configurarChipmunk;
- (void) delta:(NSTimer *)timer;
void updateShape(void *ptr, void *unused);

@end

ChipmunkTestViewController.m

#import "ChipmunkTestViewController.h"

@implementation ChipmunkTestViewController


- (void) configurarChipmunk {
    cpInitChipmunk(); // Init Chipmunk engine

    space = cpSpaceNew(); // Create new Space
    space->gravity = cpv(0, -100); // Direcction and magnitude of gravity in Space

    [NSTimer scheduledTimerWithTimeInterval:1.0f/60.0f target:self selector:@selector(delta:) userInfo:nil repeats:YES];    // NSTimer for animations

    // Create esfera Body
    cpBody *esferaBody = cpBodyNew(50.0f, INFINITY); 
    esferaBody->p = cpv(160,250);
    // Create esfera Shape
    cpShape *esferaShape = cpCircleShapeNew(esferaBody, 15.0f, cpvzero);
    esferaShape->e = 0.5f; // Elasticity
    esferaShape->u = 0.8f; // Friction
    esferaShape->data = esfera; // UIImageView association
    esferaShape->collision_type = 1;

    cpSpaceAddBody(space, esferaBody);
    cpSpaceAddShape(space, esferaShape);

}

- (void) delta:(NSTimer *)timer {
    cpSpaceStep(space, 1.0f/60.0f);     // Refresh Space info
    cpSpaceHashEach(space->activeShapes, &updateShape, nil);     // Refresh Shapes info
}

void updateShape(void *ptr, void *unused) {
    cpShape *shape = (cpShape*)ptr;
    if (shape == nil || shape->body == nil || shape->data == nil) {
        NSLog(@"Invalid Shape...");
        return;
    }
    // Refresh Shape position
    if ([(UIView*)shape->data isKindOfClass:[UIView class]]) {
        [(UIView*)shape->data setCenter:CGPointMake(shape->body->p.x, 480 - shape->body->p.y)];
    } else {
        NSLog(@"Shape updated outside updateShape function...");
    }

}

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [super viewDidLoad];

    barra = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"barra.png"]];
    barra.center = CGPointMake(160, 350);
    esfera = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"esfera.png"]];
    esfera.center = CGPointMake(160, 230);

    [self.view addSubview:barra];
    [self.view addSubview:esfera];

    [self.view setBackgroundColor:[UIColor whiteColor]];

    [self configurarChipmunk];
}

...

您应该使用macosx /目录中的iphonestatic.command脚本来构建静态库并为您复制标题，就像README所说的那样。然后，您只需将该文件夹放入项目中即可。

如果您只是将源代码复制到项目中，几乎肯定会遗漏几个非常重要的优化标记。不要这样做！

我从cocos2d + chipmunk模板中复制了chipmunk文件夹结构并构建好。

* Classes/Chipmunk/include/src for 'src' folder
* Classes/Chipmunk/chipmunk for 'include' folder

这几天我有同样的问题，我这样做了：

1.-转到项目 - ＆gt;添加到项目并找到cocos2d-iphone-0.99.5文件，然后在该目录中我添加了外部目录（包含chipmunk文件）。确保在将项目复制到目标组的文件夹（如果需要）旁边的框中有复选标记，然后单击添加按钮。

2.-我遵循本教程：http://monoclestudios.com/cocos2d_whitepaper.html（在页面中间是需要添加花栗鼠的所有信息）

3.-将#include“constraints / util.h”声明更改为：“＃include util.h”

我认为已经完成了。

Answer 4

如果您使用CocoaPods：

在xCode中点击 Pods 项目
选择 chipmunk-physics 目标

在搜索路径中将始终搜索用户路径设置为是在标题搜索路径中设置
“$ {PODS_ROOT} / Headers / Private / chipmunk-physics”到递归和

“$ {PODS_ROOT} / Headers / Public / chipmunk-physics”到递归

希望它可以帮助某人

如何将Chipmunk库包含到iPhone Xcode项目中？
