鱼上钩的概率和赢得的金币个数
//鱼是否可以被钓上来（根据概率计算）
- (BOOL)fishCanBeCatchedWithOffsetX:(CGFloat)offsetX{
if (!self.isCanCatch) return NO;
if (fabs(offsetX - self.hookX) > self.changeX/2.0) return NO; //判断是否到达了可以垂钓的点
int random = arc4random()%100; //[0,99]
DLog(@"random:%d", random);

3.被钓到的鱼
初始化被钓到的鱼方法
//初始化钓到的小鱼
- (instancetype)initCatchedFishWithType:(FishModelImageViewType)type andDirection:(FishModelImageViewDirection)dir{
if (self = [super init]){
self.direction = dir;
[self initViewWithType:type andDuration:0.5];
//重制x,y坐标， 30为鱼钩的宽度，85为鱼钩的长度
self.x = (30 - self.width)/2.0;
self.y = 85 - 6;
if (dir == FishModelImageViewFromLeft){//从左往右，默认所有的鱼都是从右往左
CGAffineTransform transform = CGAffineTransformIdentity;
transform = CGAffineTransformScale(transform, -1, 1);//镜像
transform = CGAffineTransformRotate(transform, M_PI_2);//旋转90度
self.transform = transform;
}else {
self.transform = CGAffineTransformMakeRotation(M_PI_2);
}
}
return self;
}
当鱼被抓到后，执行上钩动画
//鱼被抓到后往上游
- (void)fishCatchedMoveUpWithOffsetX:(CGFloat) offsetX{
//钩沉到鱼塘的高度为45
//位移动画
CABasicAnimation *ani = [CABasicAnimation animationWithKeyPath:@"position"];
ani.duration = 0.7;
if (self.fishType == FishModelImageViewTypeSY){//鲨鱼由于太长，所以不进行上游动画了
ani.fromValue = [NSValue valueWithCGPoint:CGPointMake(offsetX,45 + _fishWidth/2.0)];
ani.toValue = [NSValue valueWithCGPoint:CGPointMake(_hookX, 45 + _fishWidth/2.0)];
}else {
ani.fromValue = [NSValue valueWithCGPoint:CGPointMake(offsetX, (_offsetY < 60) ? 45 + _fishWidth/2.0 : _offsetY)];//离钩子近的话则不进行动画
ani.toValue = [NSValue valueWithCGPoint:CGPointMake(_hookX, 45 + _fishWidth/2.0)];
}
ani.delegate = self;
//设置这两句动画结束会停止在结束位置
[ani setValue:kFishCatchedMoveUpValue forKey:kFishCatchedMoveUpKey];
[self.layer addAnimation:ani forKey:kFishCatchedMoveUpKey];
}
