java游戏开发包_LWJGL
软件简介
LWJGL(Lightweight Java Game
Library)它可以帮助Java程序员开发有着商业性质的游戏.LWJGL为开发者提供简单易用的API来访问OpenGL (Open Graphics
Library)与OpenAL (Open Audio Library) 同也提供操作控制器(Gamepads, Steering
wheel和操纵杆)的API.
示例代码：
import org.lwjgl.Sys;
import org.lwjgl.opengl.*;
import org.lwjgl.system.glfw.*;
import java.nio.ByteBuffer;
import static org.lwjgl.opengl.GL11.*;
import static org.lwjgl.system.MemoryUtil.*;
import static org.lwjgl.system.glfw.GLFW.*;
public class HelloWorld {
private long window;
public void execute() {
System.out.println("Hello LWJGL " + Sys.getVersion() + "!");
try {
init();
loop();
glfwDestroyWindow(window);
} finally {
glfwTerminate();
}
}
private void init() {
glfwSetErrorCallback(ErrorCallback.Util.getDefault());
if ( glfwInit() != GL11.GL_TRUE )
throw new IllegalStateException("Unable to initialize GLFW");
glfwDefaultWindowHints();
glfwWindowHint(GLFW_VISIBLE, GL_FALSE);
glfwWindowHint(GLFW_RESIZABLE, GL_TRUE);
int WIDTH = 300;
int HEIGHT = 300;
window = glfwCreateWindow(WIDTH, HEIGHT, "Hello World!", NULL, NULL);
if ( window == NULL )
throw new RuntimeException("Failed to create the GLFW window");
WindowCallback.set(window, new WindowCallbackAdapter() {
@Override
public void key(long window, int key, int scancode, int action, int mods) {
if ( key == GLFW_KEY_ESCAPE && action == GLFW_RELEASE )
glfwSetWindowShouldClose(window, GL_TRUE);
}
});
ByteBuffer vidmode = glfwGetVideoMode(glfwGetPrimaryMonitor());
glfwSetWindowPos(
window,
(GLFWvidmode.width(vidmode) - WIDTH) / 2,
(GLFWvidmode.height(vidmode) - HEIGHT) / 2
);
glfwMakeContextCurrent(window);
glfwSwapInterval(1);
glfwShowWindow(window);
}
private void loop() {
GLContext.createFromCurrent();
glClearColor(1.0f, 0.0f, 0.0f, 0.0f);
while ( glfwWindowShouldClose(window) == GL_FALSE ) {
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glfwSwapBuffers(window);
glfwPollEvents();
}
}
public static void main(String[] args) {
new HelloWorld().execute();
}
}
