自定义球拍

Though the basic and advanced presets do attempt to approximate the racquets used by many players in real table tennis, the spin and speed settings of each side of the virtual racquet in ETT can be changed. In addition, because of the different grips and adaptors used by many players, bat orientation can be customised so that the virtual bat can be oriented anywhere relative to the controller.

Finding an orientation and paddle settings that are comfortable for you is one of the most important things to do to have a good experience in Eleven Table Tennis, especially if you play real table tennis at a club level.

## Customising Paddle Surface

You can use custom presets for your paddle surface which can be retrieved later, either by modifying the "custom" preset or by creating your own preset. Bounciness determines how much speed can be transferred to the ball from the bat, and spin determines how much rotation can be added to the ball. Throw coefficient changes the resultant angle from shots, particularly spin shots, with higher values resulting in angles which are closer to the direction the bat moves rather than the reflected angle.

There is no one-size-fits-all approach to surface settings. The best approach is to pick a preset and see how comfortable that feels to you, and if you feel it needs more or less speed or spin, to adjust accordingly. If you are used to real table tennis racquets which are custom assembled with quality spinny rubbers, it is best to start with the advanced preset. If you are not used to racquets like that, and are either new to table tennis, not used to anything in particular or are used to premade cheaper racquets, old worn bats etc, best to start with the default/beginner preset.

Throw coefficient, as a new addition to the game, is still being explored, but players used to real life table tennis have been finding values from 1.05 to 1.30 to match their experience best. While it does not directly increase the amount of spin a player can produce, a throw coefficient higher than 1 can allow players to use their real life technique better and it can allow a more closed bat angle to be used which does increase spin.

It is tempting for beginner players to try using maximum spin and speed settings. While this gives you more potential to generate spin and speed, it also makes your opponent's spin and speed harder to handle and control, and may be better to approach gradually as your understanding of and control over spin improves.

As many players of real table tennis have different rubbers applied to each side of their bat, ETT allows you to select "separate sides" so that you can independently select settings for each side.

**分步解析如何将游戏里的球拍参数调整到和你现实球拍类似：**

1. 点击“拍面”左边的齿轮，选择名为“进阶”的预设拍面，点击“创建预设”。输入新预设的名字。然后点击新创建的预设，这样就可以修改拍面参数了。
2. 校准回弹力（速度）。让乒乓球在你的现实球拍之上的固定高度下落。多做几次，然后切换进游戏，做同样的测试，调节回弹力，直到弹跳高度和现实一致。如果你的现实球拍是粘性胶皮，这可能有些难做到。这种情况，可以让球从更高的高度下落，让粘性不会起作用。（胶皮的粘性在游戏中还不能模拟）
3. 校准旋转。将你现实的球拍旋转到一个适当的角度，让球横向飞行击中球拍时，刚好会向上弹 起（注意让球拍不要移动）。假如你的球拍拥有真实世界不存在的0摩擦系数，这个角度应该会是45度。球拍的摩擦系数越大，它横向牵扯乒乓球的力就越大，这个实验里球拍的角度就会越“平”。（如果你的球拍是粘性胶皮，目前进行这个实验还有些困难）
4. 校准掷球系数（throw coefficient）。现在用游戏里的发球机发出上旋球，试图拉或挡球，同时调整掷球系数，直到你可以复现真实的球的弹起角度。一般来说Tenergy的胶皮会在1.15-1.2，而别的胶皮可能在1.05或更低。
5. 现在球的弹起角度以及回弹力都基本固定了，下一步有一些不那么精确，总之是这样的：当你横向搓球的时候，你的球拍会让球产生旋转。试图让现实和游戏里的旋转一致。如果你觉得游戏里旋转太大了，就降低旋转。因为旋转和掷球系数是相关联的，所以在向一个方向调整旋转的时候，需要将掷球系数往另一个方向调整。

跟随玩家反馈以及研究的进展，游戏里的物理引擎会继续更新。

## Customising orientation

In the Paddle Position sub-menu, you can alter the orientation of the paddle relative to your controller, saving presets in a similar manner to surface presets. Holding down the grip of either controller will freeze the paddle in place, allowing you to move your preferred controller into the desired position relative to the paddle. You can rotate the paddle 180° so that red and black sides are swapped (but orientation otherwise is unchanged) by using the "Flip Paddle" button in the previous "Paddle Settings" menu.

If you choose a different preferred hand in the Player Settings Menu, your orientation will be mirrored to that hand, meaning that if you hold your other controller the same way, your paddle will be correctly oriented for that hand.

Many players use not only a custom orientation but hold the controllers in very different ways to how they were intended, including 3D printed peripherals.

## Customisation tips

Try comparing VR with your real bat and how much height gentle bounces can give the ball, how much rebound there is from dropping the ball from a certain height etc.
