我一直在尝试在屏幕上显示一个模型（来自Blender的简单UVSphere）。我首先将其导出为.fbx格式，然后使用gdx-conv-win32.exe转换为.g3db格式。到目前为止，我有了这段代码，但它只显示一个空黑屏... 它只能使用此教程中找到的模型（一个.obj模型）https://xoppa.github.io/blog/loading-models-using-libgdx/。
package com.mygdx.game.screens;
/.../ imports
public class GameScreen extends MenuScreens {
public Environment environment;
public PerspectiveCamera cam;
public CameraInputController camController;
public ModelBatch modelBatch;
public Model model;
public ModelInstance instance;
AssetManager manager = new AssetManager();
public boolean loading;
public Array<ModelInstance> instances;
public GameScreen(ProjectSurvival game){
super();
this.game = game;
modelBatch = new ModelBatch();
environment = new Environment();
environment.set(new ColorAttribute(ColorAttribute.AmbientLight, 0.4f, 0.4f, 0.4f, 1f));
environment.add(new DirectionalLight().set(0.9f, 0.9f, 0.9f, 20f, 20f, 20f));
environment.add(new PointLight().set(1, 1, 1, 20, 20, 20, 500));
instances = new Array<ModelInstance>();
cam = new PerspectiveCamera(67, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
cam.position.set(1f, 1f, 1f);
cam.lookAt(0,0,0);
cam.near = 1f;
cam.far = 300f;
cam.update();
camController = new CameraInputController(cam);
Gdx.input.setInputProcessor(camController);
manager = new AssetManager();
manager.load("ship.g3db", Model.class);
loading = true;
}
private void doneLoading() {
Model test = manager.get("ship.g3db", Model.class);
ModelInstance shipInstance = new ModelInstance(test);
instances.add(shipInstance);
loading = false;
}
@Override
public void show() {
}
@Override
public void render(float delta) {
//super.render(delta);
if (loading && manager.update()) {
doneLoading();
System.out.println("loaded");
}
camController.update();
Gdx.gl.glViewport(0, 0, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT | GL20.GL_DEPTH_BUFFER_BIT);
modelBatch.begin(cam);
modelBatch.render(instances, environment);
modelBatch.end();
}
@Override
public void resize(int width, int height) {
super.resize(width, height);
}
@Override
public void pause() {
}
@Override
public void resume() {
}
@Override
public void hide() {
}
@Override
public void dispose() {
super.dispose();
modelBatch.dispose();
model.dispose();
instances.clear();
manager.dispose();
}
}
还有几个类似的话题，但是没有一个能解决我的问题...拜托，我需要帮助！
