如何在libgdx中移动鼠标滚轮速度或鼠标滚轮槽口？

[英]How to get mouse wheel speed or mouse wheel notches moved in libgdx?

原文 2016-06-21 21:49:45 1 1 java/ libgdx/ mousewheel

I know that LibGDX offers interfaces like InputProcessor and classes like InputAdapter .我知道LibGDX提供了像InputProcessor这样的接口和像InputAdapter这样的类。 They do have a scrolled method which can be override and be activated when the mouse wheel is moved.它们确实有一个滚动方法，可以在移动鼠标滚轮时覆盖和激活。

It returns a boolean value and take an integer for the argument.它返回一个boolean值并为参数取一个integer 。 The integer will either be -1 or 1 depending on the mouse wheel's scrolling direction.根据鼠标滚轮的滚动方向，整数将为 -1 或 1。 -1 is up and 1 is down. -1 上升，1 下降。

That's nice, but not fully what I need.这很好，但不完全是我需要的。 I need to figure out the mouse wheel's scrolling speed .我需要弄清楚鼠标滚轮的滚动速度。 Java does have a MouseWheelListener that allows one to find out how many notches the wheel has spun. Java 确实有一个MouseWheelListener可以让人们知道轮子旋转了多少个槽口。 I tried implementing that into LibGDX and it just didn't work.我尝试将其实施到LibGDX ，但没有奏效。

Thanks in advance!提前致谢！

You can track the wheelattacks/second by counting the mousewheel-attacks via the scrolled() method in the inputprocessor and reset the timer at every call of the render() method.您可以通过 inputprocessor 中的 scrolled() 方法计算鼠标滚轮攻击来跟踪滚轮攻击/秒，并在每次调用 render() 方法时重置计时器。 attacks*delta should give you the speed.攻击*增量应该给你速度。
