AndEngine的预测
原标题:Projection in AndEngine

我想将我的<代码>Sprite移至 AndEngine

没有人能够用一部法典帮助我? 遗憾的是,我没有看到关于<代码>AndEngine的预测的例子。

您可以使用物理处理器,然后可以操纵加速速度和速度,使之像投射器一样移动。

projectile=new Sprite(X,Y, ProjectileTextureRegion);
physprojectile = new PhysicsHandler(projectile);
projectile.registerUpdateHandler(physprojectile);
physprojectile.setVelocityX(Xvelocity);
physprojectile.setVelocityY(Yvelocity);
pyhsprojectile.setAcceleration(Accelration)  //negative acceleration
stakesprite.registerEntityModifier(new RotationModifier(0.1f, 0.0f,(float) ((360.0f/Math.PI)*Math.atan(velY/velX))));
            stake=PhysicsFactory.createCircleBody(this.mPhysicsWorld, stakesprite, BodyType.DynamicBody, FIXTURE_DEF);
            //stake = PhysicsFactory.createBoxBody(this.mPhysicsWorld, stakesprite, BodyType.DynamicBody, FIXTURE_DEF);
            stake.setBullet(true);
            stake.setLinearVelocity(new Vector2(velX, velY));
            stake.setSleepingAllowed(true);
            mScene.attachChild(stakesprite);
