Physics2D

class in UnityEngine

Description

Global settings and helpers for 2D physics.

Static Properties

AllLayers	Layer mask constant that includes all layers.
alwaysShowColliders	Should the collider gizmos always be shown even when they are not selected?
angularSleepTolerance	A rigid-body cannot sleep if its angular velocity is above this tolerance.
autoSimulation	Sets whether the physics should be simulated automatically or not.
autoSyncTransforms	Whether or not to automatically sync transform changes with the physics system whenever a Transform component changes.
baumgarteScale	The scale factor that controls how fast overlaps are resolved.
baumgarteTOIScale	The scale factor that controls how fast TOI overlaps are resolved.
callbacksOnDisable	Use this to control whether or not the appropriate OnCollisionExit2D or OnTriggerExit2D callbacks should be called when a Collider2D is disabled.
changeStopsCallbacks	Whether or not to stop reporting collision callbacks immediately if any of the objects involved in the collision are deleted/moved.
colliderAABBColor	Sets the color used by the gizmos to show all Collider axis-aligned bounding boxes (AABBs).
colliderAsleepColor	The color used by the gizmos to show all asleep colliders (collider is asleep when the body is asleep).
colliderAwakeColor	The color used by the gizmos to show all awake colliders (collider is awake when the body is awake).
colliderContactColor	The color used by the gizmos to show all collider contacts.
contactArrowScale	The scale of the contact arrow used by the collider gizmos.
defaultContactOffset	The default contact offset of the newly created colliders.
DefaultRaycastLayers	Layer mask constant that includes all layers participating in raycasts by default.
gravity	Acceleration due to gravity.
IgnoreRaycastLayer	Layer mask constant for the default layer that ignores raycasts.
linearSleepTolerance	A rigid-body cannot sleep if its linear velocity is above this tolerance.
maxAngularCorrection	The maximum angular position correction used when solving constraints. This helps to prevent overshoot.
maxLinearCorrection	The maximum linear position correction used when solving constraints. This helps to prevent overshoot.
maxRotationSpeed	The maximum angular speed of a rigid-body per physics update. Increasing this can cause numerical problems.
maxTranslationSpeed	The maximum linear speed of a rigid-body per physics update. Increasing this can cause numerical problems.
positionIterations	The number of iterations of the physics solver when considering objects' positions.
queriesHitTriggers	Do raycasts detect Colliders configured as triggers?
queriesStartInColliders	Sets the raycasts or linecasts that start inside Colliders to detect or not detect those Colliders.
showColliderAABB	Should the collider gizmos show the AABBs for each collider?
showColliderContacts	Should the collider gizmos show current contacts for each collider?
showColliderSleep	Should the collider gizmos show the sleep-state for each collider?
timeToSleep	The time in seconds that a rigid-body must be still before it will go to sleep.
velocityIterations	The number of iterations of the physics solver when considering objects' velocities.
velocityThreshold	Any collisions with a relative linear velocity below this threshold will be treated as inelastic.
