ios – 雪碧套装套装和最大为跳

概述我想在Y轴上移动一个SKSpriteNode.名为Player的SKSpriteNode没有Velocity.如果Platform与之联系,则播放器只能跳转. 每当屏幕被触动时,我想给玩家一个冲动,最小的冲动或最大的冲动 如果屏幕被轻拍,则最小脉冲应该是例如. y = 50. 如果屏幕保持,则表示手指长度在屏幕上,最大值应为例如. y = 100. 但是玩家也应该能够在最小和最大高度之间跳跃,屏幕 我想在Y轴上移动一个SKSpriteNode.名为Player的SKSpriteNode没有VeLocity.如果Platform与之联系,则播放器只能跳转.

每当屏幕被触动时,我想给玩家一个冲动,最小的冲动或最大的冲动

如果屏幕被轻拍,则最小脉冲应该是例如. y = 50.
如果屏幕保持,则表示手指长度在屏幕上,最大值应为例如. y = 100.

但是玩家也应该能够在最小和最大高度之间跳跃,屏幕不长,但也不短短,玩家只能得到y = 70的冲动.

如果屏幕保持,播放器应该跳到最大高度,掉下来,如果它再次与平台接触,则应该跳转,因为您仍然按住屏幕.

我已经尝试了这个线程中的建议答案：StackOverFlow
但这并不是最小的跳跃,也没有按下跳.

为了清楚起见：脉冲不应该在水龙头完成之后,而是在轻敲.你持有的时间越长,跳跃越长.

请注意,这是一个简单的例子,在实际应用中,您可能需要以不同的方式处理像isOnTheGround这样的状态.现在,要确定字符是否在地面上,您只需设置isOnTheGround = true,当字符与平台进行联系时,在dIDEndContact中设置为false …但是有些情况下,当与空气(如侧面接触)…

编辑：

我改变了代码,让玩家在按下时跳跃.结果如下：

重要：

实际的平台实施和联系人处理取决于你,这并没有被测试.此示例的唯一目的是向您展示如何在按下时跳转.目前,physicsWorld.speed设置为0.5,使动画更慢,因为它更容易调试,但可以将其更改为默认值(1.0).

所以,从图像可以看出,当玩家在第一个平台上时,会出现一些小跳跃(通过简单的敲击或短按).然后(玩家还在第一个平台上)长按了,玩家已经跳上了第二个平台.之后,又做了一个长时间的新闻,但这次没有释放,玩家开始从一个平台跳到另一个平台,最大的力量.

这需要大量的调整和适当的平台&联系检测,但它可以给你一个想法如何实现跳跃你问.
