Description 描述

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.
	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.
	defaultPhysicsScene		The PhysicsScene2D automatically created when Unity starts.
	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.
	jobOptions		A set of options that control how physics operates when using the job system to multithread the physics simulation.
	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.
	reuseCollisionCallbacks		Determines whether the garbage collector should reuse only a single instance of a Collision2D type for all collision callbacks.
	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.
