我希望绿色人留在地上，但我似乎无法将物理位置更改为合适的。你有什么主意吗？我拿了这个程序，只是将角色从 oto 切换到 ninja： http ://code.google.com/p/jmonkeyengine/source/browse/trunk/engine/src/test/jme3test/bullet/TestWalkingChar.java
您知道如何使相机缩小以显示整个绿色人并更改绿色人的位置以使他在地面上吗？
我注意到我可以用这个更改主字符的位置
character.setPhysicsLocation(new Vector3f(-140f, 9.9f, -9f));
但是当我输入较低的 y 坐标时，主字符会从地面下降，然后在天空中漂浮，就像他穿过地面时最终到达了所有物体的顶部一样。我可以完美地使用 Oto 运行该示例，它将主字符更改为对我不起作用的 ninja。
更新
当使用setlocaltranslation而不是setphysicallocation我的主字符时，它位于空中：
更新 2
缩放主字符后：
model.scale(0.25f);
如答案中所建议的，渲染效果要好得多：
更新 2
经过更多操作，它看起来更像我想要的方式：

// ninja.setViewDirection( new Vector3f( 1, 0, 1 ) );
// model.rotate(0.0f, -3.0f, 0.0f);
float scale = 0.25f;
model.scale(scale, scale, scale);
model.addControl(character);
character.setPhysicsLocation(new Vector3f(-141f, 10.5f, -9f));
model.setShadowMode(ShadowMode.CastAndReceive);
// model.setLocalTranslation(0, 50, 0);

getPhysicsSpace().add(character);
