我正在制作一个小的3D场景，角色可以通过按下WASD按钮来行走，但是正在播放的动画不正确，并且角色转过身来，因此看起来他在移动时正在行走。
按钮的控制代码为
private void setupKeys() {
inputManager.addMapping("wireframe", new KeyTrigger(KeyInput.KEY_T));
inputManager.addListener(this, "wireframe");
inputManager.addMapping("CharLeft", new KeyTrigger(KeyInput.KEY_A));
inputManager.addMapping("CharRight", new KeyTrigger(KeyInput.KEY_D));
inputManager.addMapping("CharUp", new KeyTrigger(KeyInput.KEY_W));
inputManager.addMapping("CharDown", new KeyTrigger(KeyInput.KEY_S));
inputManager.addMapping("CharSpace",
new KeyTrigger(KeyInput.KEY_RETURN));
inputManager
.addMapping("CharShoot", new KeyTrigger(KeyInput.KEY_SPACE));
inputManager.addListener(this, "CharLeft");
inputManager.addListener(this, "CharRight");
inputManager.addListener(this, "CharUp");
inputManager.addListener(this, "CharDown");
inputManager.addListener(this, "CharSpace");
inputManager.addListener(this, "CharShoot");
}
public void simpleUpdate(float tpf) {
Vector3f camDir = cam.getDirection().clone().multLocal(0.1f);
Vector3f camLeft = cam.getLeft().clone().multLocal(0.1f);
camDir.y = 0;
camLeft.y = 0;
walkDirection.set(0, 0, 0);
if (left) {
walkDirection.addLocal(camLeft);
}
if (right) {
walkDirection.addLocal(camLeft.negate());
}
if (up) {
walkDirection.addLocal(camDir);
}
if (down) {
walkDirection.addLocal(camDir.negate());
}
if (!character.onGround()) {
airTime = airTime + tpf;
} else {
airTime = 0;
}
if (walkDirection.length() == 0) {
if (!"Idle1".equals(animationChannel.getAnimationName())) {
animationChannel.setAnim("Idle1", 1f);
}
} else {
character.setViewDirection(walkDirection);
if (airTime > .3f) {
if (!"stand".equals(animationChannel.getAnimationName())) {
animationChannel.setAnim("stand");
}
} else if (!"Walk".equals(animationChannel.getAnimationName())) {
animationChannel.setAnim("Walk", 0.7f);
}
}
character.setWalkDirection(walkDirection);
}

我更改了一行代码以包含开始时要做的转换:
character.setViewDirection(walkDirection.add(new Vector3f(1, 0, 0)));即我添加了Vector3f(1, 0, 0)，这似乎有所帮助，现在我的角色似乎可以完美地向前和向后移动了。但是，尽管“月球行走”消失了，但侧向移动还是不完美的，也许您可以使用向量的加法确认我做了正确的事情？
更新2
当更改向量以求取反时，忍者开始像他应该的那样运动!

camDir.y = 0;

}
if (walkDirection.length() == 0) {
if (!"Idle1".equals(animationChannel.getAnimationName())) {
animationChannel.setAnim("Idle1", 1f);
}
} else {
System.out.println("setting walk direction " + walkDirection);
character.setViewDirection(walkDirection.negate());
if (airTime > .3f) {
if (!"stand".equals(animationChannel.getAnimationName())) {
animationChannel.setAnim("stand");
}
} else if (!"Walk".equals(animationChannel.getAnimationName())) {
System.out.println("in walk Walk ");
animationChannel.setAnim("Walk", 0.7f);
}
}
character.setWalkDirection(walkDirection);
}
现在剩下的问题是使char跳跃并在楼梯上移动。
最佳答案
我不是动画专家，但是如果您在播放步行动画时继续前进，应该没问题。为了获得更好的结果，您可能需要在各个仿真之间进行一些过渡(例如站立，行走，转弯)，这些过渡既可以是单独的动画，也可以通过使用动画混合来实现。
但是，很难理解您真正的问题是什么，因为描述非常简短，而且通过查看大量代码也看不到动画问题。
除此之外，如果您的问题是如何正确配置JMonkeyEngine，那么在他们的论坛上可能会更好。或在https://gamedev.stackexchange.com/。
