我想提出一个游戏LibGDX（爪哇）。

I am making a game with LibGDX (Java).

我需要的摄像机跟踪快速移动的字符。做到这一点最简单的方法是只写：

I need the camera to follow a fast moving character. The easiest way to do it is to just write this:

this.getCamera().position.set(obj.x, obj.y, 0);

不过，有没有什么算法，使这个更加顺畅？就像当相机并不严格，总是有点晚：性格那张快速正确的，摄像头下面有轻微的延迟，或者如果你突然出现的地方远，相机并没有立刻瞬移，但在行进最高时速为你当它更接近它会减慢了一下，再次找到你。

But, is there any algorithm to make this more smooth? Like when camera is not that strict, and is always a bit late: character goes quick right, camera follows with slight delay, or if you suddenly appeared somewhere far, camera doesn't teleport instantly but travels at a top speed to you when it comes closer it slows down a bit and finds you again.

有没有libgdx库的做到这一点或任何人有过这种经历？

Is there any libgdx libs that do that or anyone had this experience?

推荐答案

尝试一些简单的像lerping距离的十分之一。它的工作原理出奇地好。

Try something simple like lerping a tenth of the distance. It works surprisingly well.

float lerp = 0.1f;
Vector3 position = this.getCamera().position;
position.x += (Obj.x - position.x) * lerp;
position.y += (Obj.y - position.y) * lerp;
