/** Sample 3 - how to load an OBJ model, and OgreXML model, * a material/texture, or text. */ public class HelloAssets extends SimpleApplication {
public static void main(String[] args) { HelloAssets app = new HelloAssets(); app.start(); }
@Override public void simpleInitApp() {
//加载了一个茶壶，是个.obj文件 Spatial teapot = assetManager.loadModel("Models/Teapot/Teapot.obj"); Material mat_default = new Material( assetManager, "Common/MatDefs/Misc/ShowNormals.j3md"); teapot.setMaterial(mat_default); rootNode.attachChild(teapot);
// Create a wall with a simple texture from test_data //加载一个box中心点是Vector3f.ZERO Box box = new Box(Vector3f.ZERO, 2.5f,2.5f,1.0f); Spatial wall = new Geometry("Box", box ); Material mat_brick = new Material( assetManager, "Common/MatDefs/Misc/Unshaded.j3md"); //纹理是个.jpg文件，ColorMap是个键 mat_brick.setTexture("ColorMap", assetManager.loadTexture("Textures/Terrain/BrickWall/BrickWall.jpg")); wall.setMaterial(mat_brick); //对位置进行移动，后附加到根节点 wall.setLocalTranslation(2.0f,-2.5f,0.0f); rootNode.attachChild(wall);
// Display a line of text with a default font //显示一行默认字体的文字，我试过中文不行。guiNode是用户节点，先剔除所有子节点 guiNode.detachAllChildren(); //加载字体，guiFont用户界面字体 guiFont = assetManager.loadFont("Interface/Fonts/Default.fnt"); BitmapText helloText = new BitmapText(guiFont, false); //设置字号，内容 helloText.setSize(guiFont.getCharSet().getRenderedSize()); helloText.setText("Hello World"); //移动字体位置 helloText.setLocalTranslation(300, helloText.getLineHeight(), 0); //附加到guiNode节点 guiNode.attachChild(helloText);
// Load a model from test_data (OgreXML + material + texture) //加载忍者，这是个xml文件 Spatial ninja = assetManager.loadModel("Models/Ninja/Ninja.mesh.xml"); //必要的缩放，旋转和位置移动 ninja.scale(0.05f, 0.05f, 0.05f); ninja.rotate(0.0f, -3.0f, 0.0f); ninja.setLocalTranslation(0.0f, -5.0f, -2.0f); rootNode.attachChild(ninja); // You must add a light to make the model visible //必须加载光，让模型可见，DirectionalLight是定向光线的意思，可以看成太阳光 DirectionalLight sun = new DirectionalLight(); sun.setDirection(new Vector3f(-0.1f, -0.7f, -1.0f)); rootNode.addLight(sun);
