Defined in: packages/physics/utils/ContactProcessedUtil.ts:8

Collision processing utility

Constructors

Constructor

new ContactProcessedUtil(): ContactProcessedUtil

Returns

ContactProcessedUtil

Methods

registerCollisionCallback()

static registerCollisionCallback(pointer, callback): void

Defined in: packages/physics/utils/ContactProcessedUtil.ts:18

Register a collision event.

Parameters

pointer

number

Pointer to the physics object

callback

Callback

Event callback

Returns

void

---

unregisterCollisionCallback()

static unregisterCollisionCallback(pointer): void

Defined in: packages/physics/utils/ContactProcessedUtil.ts:32

Unregister a collision event.

Parameters

pointer

number

Pointer to the physics object

Returns

void

---

addIgnoredPointer()

static addIgnoredPointer(pointer): void

Defined in: packages/physics/utils/ContactProcessedUtil.ts:64

Add a pointer to the ignored set. Once added, no collision event will be triggered when any object collides with the object referenced by this pointer.

Parameters

pointer

number

Pointer to the physics object

Returns

void

---

removeIgnoredPointer()

static removeIgnoredPointer(pointer): void

Defined in: packages/physics/utils/ContactProcessedUtil.ts:74

Remove a pointer from the ignored set.

Parameters

pointer

number

Pointer to the physics object

Returns

void

---

isIgnored()

static isIgnored(pointer): boolean

Defined in: packages/physics/utils/ContactProcessedUtil.ts:82

Check whether the pointer is in the ignored set.

Parameters

pointer

number

Pointer to the physics object

Returns

boolean

---

isCollision()

static isCollision(pointer): boolean

Defined in: packages/physics/utils/ContactProcessedUtil.ts:90

Check whether the pointer has a registered collision event.

Parameters

pointer

number

Pointer to the physics object

Returns

boolean

---

performCollisionTest()

static performCollisionTest(bodyA, bodyB?): object

Defined in: packages/physics/utils/ContactProcessedUtil.ts:129

Perform a one-shot collision test. If bodyB is provided, tests whether bodyA collides with bodyB. Otherwise, tests whether bodyA collides with any other rigid body.

Parameters

bodyA

btRigidBody

The first rigid body.

bodyB?

btRigidBody

(Optional) The second rigid body.

Returns

object

An object with collision information if a collision occurred; otherwise null.

cpPtr

cpPtr: number

colObj0Wrap

colObj0Wrap: btCollisionObjectWrapper

colObj1Wrap

colObj1Wrap: btCollisionObjectWrapper

partId0

partId0: number

index0

index0: number

partId1

partId1: number

index1

index1: number

---

checkCollision()

static checkCollision(bodyA, bodyB): boolean

Defined in: packages/physics/utils/ContactProcessedUtil.ts:174

Collision check: determines whether two rigid bodies are currently colliding.

Parameters

bodyA

btRigidBody

bodyB

btRigidBody

Returns

boolean

boolean
