htc vive 游戏切换武器功能思路以及demo（unity，c#）

标签：

</pre>个人感觉vr游戏或者展示类程序的灵魂就是真实感以及身临其境的感觉，如果场景中加入了大量的ui会破坏真实感，影响感觉，因此我觉得ui这种东西在vr里应该尽量转化为现实物体，比如显示屏，按钮等，一来增加了交互，二来也在增加真实感的同时也实现了ui的功能。<span style="font-family:黑体; word-wrap:break-word; color:rgb(105,105,105); font-size:16px; line-height:25px"><span style="font-size:24px; word-wrap:break-word"><span style="word-wrap:break-word; font-weight:700">  以上是废话，意思就是ui最好做成3d的，个人感觉。。。。。。<br style="word-wrap:break-word" /></span></span></span><p><span style="font-family:黑体; word-wrap:break-word; color:rgb(105,105,105); font-size:16px; line-height:25px"><span style="font-size:24px; word-wrap:break-word"><span style="word-wrap:break-word; font-weight:700">  htc vive 在steam上有款游戏叫HoverJunkers，个人感觉是目前所有htc viveFPS游戏里的顶端作品了，沉浸感很强，虽然是虚构出来的科幻的末世风格，枪械手感做的也非常有感觉，感觉这款游戏里的换枪功能做的手感不错，所以用自己的思路模仿着做了一下，大体实现了功，界面简陋，代码写的也太嫩，有很多需要优化的地方，因此仅仅提供一个思路，不仅仅可以换钱，也可以当做其他的功能使用，算是抛砖引玉，大家有体验更好的这类交互希望也一起分享一下.</span></span></span></p><p><span style="font-family:黑体;
