Static Variables 静态变量

AllLayers	Layer mask constant that includes all layers. 图层遮罩常量，包括所有层。
angularSleepTolerance	A rigid-body cannot sleep if its angular velocity is above this tolerance. 刚体的角速度如果超过这个公差，是无法进入休眠状态的。
baumgarteScale	The scale factor that controls how fast overlaps are resolved. 控制如何快速解决重叠的缩放系数。
baumgarteTOIScale	The scale factor that controls how fast TOI overlaps are resolved.(TOI: Time of Impact) 控制如何快速解决撞击时重叠的缩放系数。（TOI：撞击的时间）
DefaultRaycastLayers	Layer mask constant that includes all layers participating in raycasts by default. 一个图层遮罩常量，包含所有默认参与光线投射的图层。
gravity	Acceleration due to gravity. 重力加速度。
IgnoreRaycastLayer	Layer mask constant for the default layer that ignores raycasts. 一个图层遮罩常量，包含默认忽略参与光线投射的图层。
linearSleepTolerance	A rigid-body cannot sleep if its linear velocity is above this tolerance. 刚体的线速度如果超过这个公差，是无法进入休眠状态的。
maxAngularCorrection	The maximum angular position correction used when solving constraints. This helps to prevent overshoot. 最大角位置修正在解决约束的时候被使用。这有助于防止运动过度。
maxLinearCorrection	The maximum linear position correction used when solving constraints. This helps to prevent overshoot. 最大线性位置修正在解决约束的时候被使用。这有助于防止运动过度。
maxRotationSpeed	The maximum angular speed of a rigid-body per physics update. Increasing this can cause numerical problems. 每次物理更新刚体的最大角速度。增加这个值会导致数值问题。
maxTranslationSpeed	The maximum linear speed of a rigid-body per physics update. Increasing this can cause numerical problems. 每次物理更新刚体的最大线速度。增加这个值会导致数值问题。
positionIterations	The number of iterations of the physics solver when considering objects' positions. 当考虑对象位置时，物理求解器的迭代次数。
raycastsHitTriggers	Do raycasts detect Colliders configured as triggers? 是否让光线投射检测触发器？
timeToSleep	The time in seconds that a rigid-body must be still before it will go to sleep. 以秒为单位，刚体将要休眠前，在这段时间内必须保持静止。
velocityIterations	The number of iterations of the physics solver when considering objects' velocities. 当考虑对象速度时，物理求解器的迭代次数。
velocityThreshold	Any collisions with a relative linear velocity below this threshold will be treated as inelastic. 任何碰撞的相对线速度低于这个临界值将被视为非弹性的碰撞。
