更新： WorldConfiguration 和 World 还是一样的，
WorldConfiguration setup = new WorldConfigurationBuilder()
.with(new HelloSystemArtemis())
.with(new RenderSystem(batch, environment))
.with(new BulletSystem(this))
.with(new PlayerSystem(perspectiveCamera, batch, gameUi, this))
.with(new AthmosphereSystem(modelComponent,
bulletComponent))
.with(new MovementSystem(this))
.with(new StatusSystem(this))
.with(new EnemySystem(this))
.build();
World world = new World(setup);
world.setDelta(delta);
int entityId = world.create();
world.edit(entityId).create(HelloComponentArtemis.class).message = "\n\rHello Oxyddians!\n\r";
出于清晰的原因决定发布完整的代码，实际上无法解释问题出在哪里，即使我遇到了指向我的错误
@All({ModelComponentArtemis.class, ModelComponentArtemis.class})
public class AthmosphereSystem extends BaseSystem {
private static OxyddiA game;
private static Assets assets = new Assets();
private ComponentMapper<ModelComponentArtemis> mc;
private ComponentMapper<BulletComponentArtemis> bc;
public AthmosphereSystem(ComponentMapper<ModelComponentArtemis> mc,
ComponentMapper<BulletComponentArtemis> bc) {
this.mc = mc;
this.bc = bc;
}
@Override
protected void processSystem() {
int entity = world.create();
ModelComponentArtemis mc = new ModelComponentArtemis(assets.Athmosphere,0,0,0);
mc.create(entity); //Not working
BulletComponentArtemis bc = new BulletComponentArtemis();
btCollisionShape shape = Bullet.obtainStaticNodeShape(assets.Athmosphere.nodes);
bc.bodyInfo = new btRigidBody.btRigidBodyConstructionInfo(0, null, shape, Vector3.Zero);
bc.body = new btRigidBody(bc.bodyInfo);
bc.body.userData = entity;
bc.motionState = new MotionState(mc.instance.transform);
((btRigidBody) bc.body).setMotionState(bc.motionState);
bc.create(entity); //Not working
return entity; //Not working as well
}
}
此方法中使用的 ModelComponent
public class ModelComponentArtemis extends Component {
public Model model;
public ModelInstance instance;
public ModelComponentArtemis(Model model, float x, float y, float z)
{
this.model = model;
this.instance = new ModelInstance(model, new Matrix4().setToTranslation(x, y, z));
}
public void reset() {
}
}
此方法中使用的 BulletComponent
public class BulletComponentArtemis extends Component {
public MotionState motionState;
public btRigidBody.btRigidBodyConstructionInfo bodyInfo;
public btCollisionObject body;
public Model model;
public void init() {
ModelComponentArtemis modelComponent = new ModelComponentArtemis(model,0,0,0);
BulletComponentArtemis bulletComponent = new BulletComponentArtemis();
btCollisionShape shape = Bullet.obtainStaticNodeShape(model.nodes);
bulletComponent.bodyInfo = new btRigidBody.btRigidBodyConstructionInfo(0, null, shape, Vector3.Zero);
bulletComponent.body = new btRigidBody(bulletComponent.bodyInfo);
Object bCuD = null;
bulletComponent.body.userData = bCuD;
bulletComponent.motionState = new MotionState(modelComponent.instance.transform);
((btRigidBody) bulletComponent.body).setMotionState(bulletComponent.motionState);
}
public void reset() {
}
}
当然还有这个项目中使用的 BulletSystem
@All(ModelComponentArtemis.class)
public class BulletSystem extends EntitySystem
{
public Entity e;
public final btCollisionConfiguration collisionConfiguration;
public final btCollisionDispatcher dispatcher;
public final btBroadphaseInterface broadphase;
public final btConstraintSolver solver;
public final btDiscreteDynamicsWorld collisionWorld;
public GameWorld gameWorld;
public PreGameWorld preGameWorld;
private final btGhostPairCallback ghostPairCallback;
public final int maxSubSteps = 5;
public final float fixedTimeStep = 0.2f / 60f;
private EntityContactListener myContactListener;
public BulletSystem(GameWorld gameWorld)
{
super(Aspect.all(ModelComponentArtemis.class));
this.gameWorld = gameWorld;
myContactListener = new EntityContactListener();
myContactListener.enable();
collisionConfiguration = new btDefaultCollisionConfiguration();
dispatcher = new btCollisionDispatcher(collisionConfiguration);
broadphase = new btAxisSweep3(new Vector3(-1000, -1000, -1000), new Vector3(1000, 1000, 1000));
solver = new btSequentialImpulseConstraintSolver();
collisionWorld = new btDiscreteDynamicsWorld(dispatcher, broadphase, solver, collisionConfiguration);
ghostPairCallback = new btGhostPairCallback();
broadphase.getOverlappingPairCache().setInternalGhostPairCallback(ghostPairCallback);
this.collisionWorld.setGravity(new Vector3(0f, -0.5f, 0f));
}
public BulletSystem(PreGameWorld preGameWorld)
{
this.preGameWorld = preGameWorld;
myContactListener = new EntityContactListener();
myContactListener.enable();
collisionConfiguration = new btDefaultCollisionConfiguration();
dispatcher = new btCollisionDispatcher(collisionConfiguration);
broadphase = new btAxisSweep3(new Vector3(-1000, -1000, -1000), new Vector3(1000, 1000, 1000));
solver = new btSequentialImpulseConstraintSolver();
collisionWorld = new btDiscreteDynamicsWorld(dispatcher, broadphase, solver, collisionConfiguration);
ghostPairCallback = new btGhostPairCallback();
broadphase.getOverlappingPairCache().setInternalGhostPairCallback(ghostPairCallback);
this.collisionWorld.setGravity(new Vector3(0f, -0.5f, 0f));
}
public void update(float deltaTime)
{
collisionWorld.stepSimulation(deltaTime, maxSubSteps, fixedTimeStep);
}
protected void processSystem(int entityId) {
this.world.getEntity(entityId).getComponent(BulletComponentArtemis.class);
}
@Override
protected void processSystem() {
}
public void dispose()
{
collisionWorld.dispose();
if (solver != null) solver.dispose();
if (broadphase != null) broadphase.dispose();
if (dispatcher != null) dispatcher.dispose();
if (collisionConfiguration != null)
collisionConfiguration.dispose();
ghostPairCallback.dispose();
}
}
考虑到所有这些，我知道我找不到任何解决方案，也许对于任何希望提供帮助的人来说会更清楚谢谢无论如何。
