Global settings and helpers for 2D physics.

정적 변수

AllLayersLayer mask constant that includes all layers.
alwaysShowCollidersShould the collider gizmos always be shown even when they are not selected?
angularSleepToleranceA rigid-body cannot sleep if its angular velocity is above this tolerance.
autoSimulationSets whether the physics should be simulated automatically or not.
autoSyncTransformsWhether or not to automatically sync transform changes with the physics system whenever a Transform component changes.
baumgarteScaleThe scale factor that controls how fast overlaps are resolved.
baumgarteTOIScaleThe scale factor that controls how fast TOI overlaps are resolved.
callbacksOnDisableUse this to control whether or not the appropriate OnCollisionExit2D or OnTriggerExit2D callbacks should be called when a Collider2D is disabled.
colliderAABBColorSets the color used by the gizmos to show all Collider axis-aligned bounding boxes (AABBs).
colliderAsleepColorThe color used by the gizmos to show all asleep colliders (collider is asleep when the body is asleep).
colliderAwakeColorThe color used by the gizmos to show all awake colliders (collider is awake when the body is awake).
colliderContactColorThe color used by the gizmos to show all collider contacts.
contactArrowScaleThe scale of the contact arrow used by the collider gizmos.
defaultContactOffsetThe default contact offset of the newly created colliders.
defaultPhysicsSceneThe PhysicsScene2D automatically created when Unity starts.
DefaultRaycastLayersLayer mask constant that includes all layers participating in raycasts by default.
gravityAcceleration due to gravity.
IgnoreRaycastLayerLayer mask constant for the default layer that ignores raycasts.
jobOptionsA set of options that control how physics operates when using the job system to multithread the physics simulation.
linearSleepToleranceA rigid-body cannot sleep if its linear velocity is above this tolerance.
maxAngularCorrectionThe maximum angular position correction used when solving constraints. This helps to prevent overshoot.
maxLinearCorrectionThe maximum linear position correction used when solving constraints. This helps to prevent overshoot.
maxRotationSpeedThe maximum angular speed of a rigid-body per physics update. Increasing this can cause numerical problems.
maxTranslationSpeedThe maximum linear speed of a rigid-body per physics update. Increasing this can cause numerical problems.
positionIterationsThe number of iterations of the physics solver when considering objects' positions.
queriesHitTriggersDo raycasts detect Colliders configured as triggers?
queriesStartInCollidersSets the raycasts or linecasts that start inside Colliders to detect or not detect those Colliders.
reuseCollisionCallbacksDetermines whether the garbage collector should reuse only a single instance of a Collision2D type for all collision callbacks.
showColliderAABBShould the collider gizmos show the AABBs for each collider?
showColliderContactsShould the collider gizmos show current contacts for each collider?
showColliderSleepShould the collider gizmos show the sleep-state for each collider?
timeToSleepThe time in seconds that a rigid-body must be still before it will go to sleep.
velocityIterationsThe number of iterations of the physics solver when considering objects' velocities.
velocityThresholdAny collisions with a relative linear velocity below this threshold will be treated as inelastic.
