參考SpriteKit 創建遊戲的教程今天自己動手做瞭一下，現在記錄一下自己怎麼做的，今天之做瞭第一步，一共有三個部分。
第一步，項目搭建。
項目所用圖片資源：點擊打開鏈接
1.在Xcode打開之後，選擇File
Menu > New > Project,然後你可能會看到下面的示意圖所顯示的內容：
隨便起個名字，我就叫它：2014airplane瞭。
2.創建成功後，點擊運行如果模板運行成功後接著來。
3.復制這些圖片到你項目中的指定目錄並且要確保你的“Copy
Items into destination group’s folder（如果需要）”被選上。
4.代碼修改如下：
MyScene.h中的代碼：
//
// MyScene.h
// 2014airplane
//
// Copyright (c) 2014年 com.wildcat. All rights reserved.
//
#import
#import
@interface MyScene : SKScene{
CGRect screenRect;
CGFloat screenHeight;
CGFloat screenWidth;
double currentMaxAccelX;
double currentMaxAccelY;
}
//聲明變量
//聲明運動管理器
@property (strong,nonatomic)CMMotionManager *motionManager;
@property SKSpriteNode *plane; //飛機
@property SKSpriteNode *planeShadow; //飛機倒影
@property SKSpriteNode *propeller; //螺旋槳
@end
MyScene.m中的代碼：
//
// MyScene.m
// 2014airplane
//

#import "MyScene.h"
@implementation MyScene
-(id)initWithSize:(CGSize)size {
if (self = [super initWithSize:size]) {
//設置場景大小
screenRect=[[UIScreen mainScreen] bounds];
screenHeight=screenRect.size.height;
screenWidth=screenRect.size.width;
//設置飛機圖片
_plane=[SKSpriteNode spriteNodeWithImageNamed:@"PLANE 8 N.png"];
_plane.scale=0.6; //縮放比例
_plane.zPosition=2; //縱坐標
_plane.position=CGPointMake(screenWidth/2, 15+_plane.size.height/2); //設置飛機的初始位置
[self addChild:_plane];
//添加背景
SKSpriteNode *backgroud=[SKSpriteNode spriteNodeWithImageNamed:@"airPlanesBackground.png"];
backgroud.position=CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame));
[self addChild:backgroud];
//添加飛機背景
_planeShadow=[SKSpriteNode spriteNodeWithImageNamed:@"PLANE 8 SHADOW.png"];
_planeShadow.scale=0.6;
_planeShadow.zPosition=1;
_planeShadow.position=CGPointMake(screenWidth/2+15, _planeShadow.size.height/2);
[self addChild:_planeShadow];
//添加螺旋槳
_propeller=[SKSpriteNode spriteNodeWithImageNamed:@"PLANE PROPELLER 1.png"];
_propeller.scale=0.2;
_propeller.position=CGPointMake(screenWidth/2, _plane.size.height+10);
SKTexture *propeller1=[SKTexture textureWithImageNamed:@"PLANE PROPELLER 1.png"];
SKTexture *propeller2=[SKTexture textureWithImageNamed:@"PLANE PROPELLER 2.png"];
SKAction *spin=[SKAction animateWithTextures:@[propeller1,propeller2] timePerFrame:0.1];
SKAction *spinForever=[SKAction repeatActionForever:spin];
[_propeller runAction:spinForever];
[self addChild:_propeller];
//設置運動管理器
self.motionManager=[[CMMotionManager alloc] init];
self.motionManager.accelerometerUpdateInterval=0.2;
[self.motionManager startAccelerometerUpdatesToQueue:[NSOperationQueue currentQueue] withHandler:^(CMAccelerometerData *accelerometerData, NSError *error) {
[self outputAccelertionData:accelerometerData.acceleration];
if (error) {
NSLog(@"%@",error);
}
}];
}
return self;
}
-(void)outputAccelertionData:(CMAcceleration)acceleration{
currentMaxAccelX=0;
currentMaxAccelY=0;
if (fabs(acceleration.x>fabs(currentMaxAccelX))) {
currentMaxAccelX=acceleration.x;
}
if (fabs(acceleration.y>fabs(currentMaxAccelY))) {
currentMaxAccelY=acceleration.y;
}
}
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
/* Called when a touch begins */
}
//Update現在主要處理兩件事情：更新你的位置和交換不同的sprite
-(void)update:(CFTimeInterval)currentTime {
/* Called before each frame is rendered */
//NSLog(@"one second");
float maxY = screenWidth - _plane.size.width/2;
float minY = _plane.size.width/2;
float maxX = screenHeight - _plane.size.height/2;
float minX = _plane.size.height/2;
float newY = 0;
float newX = 0;
if(currentMaxAccelX > 0.05){
newX = currentMaxAccelX * 10;
_plane.texture = [SKTexture textureWithImageNamed:@"PLANE 8 R.png"];
}
else if(currentMaxAccelX < -0.05){
newX = currentMaxAccelX*10;
_plane.texture = [SKTexture textureWithImageNamed:@"PLANE 8 L.png"];
}
else{
newX = currentMaxAccelX*10;
_plane.texture = [SKTexture textureWithImageNamed:@"PLANE 8 N.png"];
}
newY = 6.0 + currentMaxAccelY *10;
float newXshadow = newX+_planeShadow.position.x;
float newYshadow = newY+_planeShadow.position.y;
newXshadow = MIN(MAX(newXshadow,minY+15),maxY+15);
newYshadow = MIN(MAX(newYshadow,minX-15),maxX-15);
float newXpropeller = newX+_propeller.position.x;
float newYpropeller = newY+_propeller.position.y;
newXpropeller = MIN(MAX(newXpropeller,minY),maxY);
newYpropeller = MIN(MAX(newYpropeller,minX+(_plane.size.height/2)-5),maxX+(_plane.size.height/2)-5);
newX = MIN(MAX(newX+_plane.position.x,minY),maxY);
newY = MIN(MAX(newY+_plane.position.y,minX),maxX);
_plane.position = CGPointMake(newX, newY);
_planeShadow.position = CGPointMake(newXshadow, newYshadow);
_propeller.position = CGPointMake(newXpropeller, newYpropeller);
}
@end
運行結果如下：
