7、示例4：Hello States

1.2 详细说明

// Get a URL that points to the texture we're going to load

URL monkeyLoc; monkeyLoc=HelloStates.class.getClassLoader().getResource("jmetest/data/images/Monkey.jpg");

获取图片资源的路径。

// Get a TextureState

TextureState ts=display.getRenderer().createTextureState();

// Use the TextureManager to load a texture

Texture t=TextureManager.loadTexture(monkeyLoc,Texture.MinificationFilter.BilinearNearestMipMap,Texture.MagnificationFilter.Bilinear);

// Assign the texture to the TextureState

ts.setTexture(t);

// Signal that b should use renderstate ts

b.setRenderState(ts);

把立方体的六个面加载上图片。效果如图：

// Create a point light

PointLight l=new PointLight();

// Give it a location

l.setLocation(new Vector3f(0,10,5));

// Make it a red light

l.setDiffuse(ColorRGBA.red.clone());

// Enable it

l.setEnabled(true);

// Create a LightState to put my light in

LightState ls=display.getRenderer().createLightState();

// Attach the light

ls.attach(l);

这是设置一个点光源（代码rootNode.setLightCombineMode(LightCombineMode.Off);得去掉），效果如图：

将材质设为绿色：

// Get a MaterialState

MaterialState ms=display.getRenderer().createMaterialState();

// Give the MaterialState an emissive tint

ms.setEmissive(new ColorRGBA(0f,.2f,0f,1));

b.setRenderState(ms);
