如何将 Chipmunk 库包含到 iPhone Xcode 项目中？

Question

[已解决]

我从 cocos2d+chipmunk 模板复制了chipmunk文件夹结构并构建成功。

• Classes/Chipmunk/include/src 用于“src”文件夹
• Classes/Chipmunk/chipmunk 用于“include”文件夹

感谢 Beta 的帮助。

我下载了chipmunk 5.3.1 并尝试使用一个简单的示例，但收到此编译错误：

Undefined symbols:
  "_cpSpaceStep", referenced from:
      -[ChipmunkTestViewController delta:] in ChipmunkTestViewController.o

      -[ChipmunkTestViewController configurarChipmunk] in ChipmunkTestViewController.o

我不确定是否正确添加了Chipmunk 库，我必须包含chipmunk .tgz 中的哪些源？

代码如下：

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复制标头，如自述文件所述。然后您所要做的就是将该文件夹放入您的项目中。

如果您只是将源代码复制到项目中，那么您几乎肯定会丢失几个非常重要的优化标志。不要这样做！

我从 cocos2d+chipmunk 模板复制了chipmunk文件夹结构并构建成功。

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

我今天有同样的问题，我这样做了：

1.- 转到项目 -->添加到项目并找到 cocos2d-iphone-0.99.5 文件，然后从该目录中添加 External 目录（包含花栗鼠文件）。请务必选中“将项目复制到目标组的文件夹（如果需要）”旁边的复选框，然后单击“添加”按钮。

2.- 我遵循本教程： http://monoclestudios.com/cocos2d_whitepaper.html （在中间该页面的内容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。

Answer 4

如果您使用 CocoaPods：

1. 在 xCode 中单击您的 Pods 项目，
2. 在搜索路径中选择chipmunk-physicals目标
3. ，设置始终搜索用户路径< /strong> 为
4. 标头搜索路径中的

YES，将“${PODS_ROOT}/Headers/Private/chipmunk-physicals”设置为递归，并将

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