Cult3D 高级教程之改变材质颜色的java代码

　　样使用这个class：
　　定义一个新的颜色color,比如" private Color red = new Color ( 198, 58, 41); " 增加该颜色的变量名variable name到colors数组,使用changeColor方法来循环改变颜色。

　　修改如下设置
import com.cult3d.*; import com.cult3d.world.*; import java.awt.Color; import java.awt.Image; import java.awt.Graphics; public class ColorSwap implements Cult3DScript, Runnable { // TEXTURE_NAME 的值是你要改变得纹理的名字 private static final String TEXTURE_NAME = "MADAROSE"; // if you want to add more colors add a Color instance here // and add it to the colors array.
