间距精灵在屏幕上

Question

大家好我希望有人可以告诉我如何减少从阵列中添加的精灵之间的间距，当它们均匀间隔和居中时，我需要减小精灵之间的宽度

整个代码块就足以测试间距

了

int images = 5
     for(int i = 0; i < images; ++i)
         {
             ///load same ammount of spriteimages as images
            SKSpriteNode *sprite = 
            [SKSpriteNode spriteNodeWithImageNamed:@"Null.jpg"];

            sprite.name = @"sprite.name =Sprite%d",[NSString stringWithFormat:@"%i",i];
            NSLog(@"***sprite.name %@",[NSString stringWithFormat:@"%i",i]);

             ///spriteSpacing
             float offsetFraction = ((float)(i + 1)) / (images + 1);
             float widthOfScreen =self.frame.size.width;

             sprite.position = CGPointMake(widthOfScreen * offsetFraction,self.frame.size.height/2 +200);
            [self addChild:sprite];
        }

Answer 1

试试看看会发生什么

float widthOfScreen = self.frame.size.width + 100.0;

Answer 2

最后我做了这个

float padding = 100.0f;
        int blockWidth = [SKSpriteNode spriteNodeWithImageNamed:@"Null.jpg"].size.width;
        float xOffset = (self.frame.size.width - (blockWidth * images + padding * (images-1))) / 2;
        //float xOffset = (self.frame.size.width - (blockWidth * numberOfBlocks + padding * (numberOfBlocks-1))) / 2;
        float StartPoint = xOffset+blockWidth/2;
         for(int i = 0; i < images; ++i)
         {

        SKSpriteNode *sprite = [SKSpriteNode spriteNodeWithImageNamed:@"Null.jpg"];


         ///set start point of 1st sprite to load 
         if (i>0&&i<images)
         {

             StartPoint = StartPoint+ blockWidth+padding;
         }

         //increment sprite position
         else if (i==images)
         {

              StartPoint = StartPoint+ blockWidth;
         }
         sprite.position = CGPointMake(StartPoint, self.frame.size.height * 0.8f);
        [self addChild:sprite];
    }
