使用 LibGDX 顺时针旋转图像

问题描述

我们如何使用 LibGDX 顺时针旋转图像?我正在寻找的是当加载图像时，假设一个星，我需要将它从屏幕的开头水平旋转到屏幕的结尾，随着星的旋转，我该如何在 libgdx 中做到这一点?

How can we rotate a Image Clockwise using LibGDX? what i am looking is when a image is loaded,suppose a star, i need to rotate it from beginning of screen to end of the screen horizontally, with star rotating,how can i do that in libgdx?

推荐答案

使用 SpriteBatch 绘制纹理时，可以使用包含旋转的绘制函数之一.此 javadoc 具有所有绘图功能:SpriteBatch

When you draw the Texture with your SpriteBatch, you can use one of the draw functions that includes rotation. This javadoc has all the draw functions: SpriteBatch

可以为位置和旋转保留一个变量，并在每次渲染时增加位置的旋转和x分量，使其在水平移动的同时旋转.

You can keep a variable for position and rotation, and increase the rotation and x component of the position each time you render to make it rotate while moving horizontally.
