| Touch结构体 | 摘要 | 说明 |
| fingerId | The unique index for the touch. | 触摸的唯一索引。 |
| position | The position of the touch in pixel coordinates. | 触摸在像素坐标中的位置。 |
| rawPosition | The raw position used for the touch. | 用于触摸的原始位置。 |
| deltaPosition | The position delta since last change. | 上次改变后的位置。 |

If Input.touchPressureSupported returns false, the value of this property will always be 1.0f. | 当前施加在触摸上的压力。1.0f被认为是平均触摸的压力。如果输入。touchPressureSupported返回false，此属性的值将始终为1.0f。 |
| maximumPossiblePressure | The maximum possible pressure value for a platform. If Input.touchPressureSupported returns false, the value of this property will always be 1.0f. | 平台可能的最大压力值。如果输入。touchPressureSupported返回false，此属性的值将始终为1.0f。 |
| type | A value that indicates whether a touch was of Direct, Indirect (or remote), or Stylus type. | 指示触摸是直接、间接(或远程)或手写笔类型的值。 |
| altitudeAngle | Value of 0 radians indicates that the stylus is parallel to the surface, pi/2 indicates that it is perpendicular. | |

| radius | An estimated value of the radius of a touch. Add radiusVariance to get the maximum touch size, subtract it to get the minimum touch size. | 触摸半径的估计值。添加radiusVariance得到最大的触摸尺寸，减去它得到最小的触摸尺寸。 |
| radiusVariance | The amount that the radius varies by for a touch. | 触摸半径的变化量。 |
| TouchPhase枚举 | 说明 |
| Began | 一根手指触到了屏幕。 |
| Moved | 一根手指在屏幕上移动。 |
