如何设置SKScene的背景图像？ [英] How to set the background image for a SKScene?

问题描述

由于目前无法将 SKScene 的颜色设置为 clearColor ，所以

Since currently it is not possible to set the color to of a SKScene to clearColor, by doing

-(id)initWithSize:(CGSize)size {
    if (self = [super initWithSize:size]) {


        self.backgroundColor = [SKColor clearColor];

    }
    return self;
}

如下所示： LINK

然后 怎么能一个设置 SKScene 的背景图片？请尽可能具体，示例代码会很棒！

Then how can one set the background image for a SKScene? Please be as specific as possible, sample code would be great!

推荐答案

使用 SKSpriteNode 以场景为中心：

-(id)initWithSize:(CGSize)size {    
    if (self = [super initWithSize:size]) {
        // Replace @"Spaceship" with your background image:
        SKSpriteNode *sn = [SKSpriteNode spriteNodeWithImageNamed:@"Spaceship"];

        sn.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame));
        sn.name = @"BACKGROUND";

        [self addChild:sn];
    }
    return self;
}
