我认为我已经将Box2d配置为对任何身体都有某种最大速度,但我不确定.我施加了一种冲动(100000000, 100000000),身体的移动速度一样快(100, 100)- 这根本不是那么快.

我正在使用Box2d XNA C#端口.

我的游戏是自上而下的2d.

以下是一些可能相关的代码:

private readonly Vector2 GRAVITY = new Vector2(0, 0);

    public void initializePhysics(ContactReporter contactReporter)
    {
        world = new World(GRAVITY, true);
        IContactListener contactListener = contactReporter;
        world.ContactListener = contactListener;
    }

    public void Update(GameTime gameTime)
        {
     // ...

            worldState.PhysicsWorld.Step((float)gameTime.ElapsedGameTime.TotalSeconds, 10, 10);

     //...
        }

以下是一些应用冲动的示例代码:

    private void ApplyImpulseFromInput()
    {
        Vector2 movementImpulse = new Vector2();

        if (inputReader.ControlActivation(ActionInputType.MOVE_LEFT) == 1f)
        {
            movementImpulse.X = -Constants.PLAYER_IMPULSE_CONSTANT;
        } else if (inputReader.ControlActivation(ActionInputType.MOVE_RIGHT) == 1f)
        {
            movementImpulse.X = Constants.PLAYER_IMPULSE_CONSTANT; ; …
