Class: ManifoldMap
physics/manifoldMap.ManifoldMap
Represents a 2 layered {@link Map} containing Manifolds for CollisionObject pairs.
Constructors
constructor
• new ManifoldMap()
Properties
map
• map: Map<CollisionObject, Map<CollisionObject, Manifold>>
Defined in
src/physics/manifoldMap.ts:9
Methods
addManifold
▸ addManifold(a, b, m): void
Adds a manifold to the map with the top level key being a and inner key being b.
If a manifold is already in the map with key [b, a] then that manifold will be updated instead.
Parameters
| Name | Type | Description |
|---|---|---|
a | CollisionObject | The first object for the key |
b | CollisionObject | The second object for the key |
m | Manifold | The manifold to insert |
Returns
void
Defined in
src/physics/manifoldMap.ts:79
getAllManifolds
▸ getAllManifolds(): Manifold[]
Gets all the manifolds in the map and returns them as a contiguous array.
Returns
Manifold[]
All the manifolds in the map as an array
Defined in
src/physics/manifoldMap.ts:16
getManifold
▸ getManifold(a, b): Manifold
Finds a manifold in the ManifoldMap.
Parameters
| Name | Type | Description |
|---|---|---|
a | CollisionObject | The first collision object |
b | CollisionObject | The second collision object |
Returns
The manifold for the collision between a and b or undefined.
Defined in
src/physics/manifoldMap.ts:34
getManifoldKey
▸ getManifoldKey(a, b): Object
Finds the correct key in the map for objects a and b.
Parameters
| Name | Type | Description |
|---|---|---|
a | CollisionObject | An object in the key |
b | CollisionObject | An object in the key |
Returns
Object
The manifold key or undefined
| Name | Type |
|---|---|
key | CollisionObject |
top | CollisionObject |
Defined in
src/physics/manifoldMap.ts:54
killAllManifolds
▸ killAllManifolds(): void
Sets isDead to true for every manifold in the map.
Returns
void
Defined in
src/physics/manifoldMap.ts:156
removeDeadManifolds
▸ removeDeadManifolds(): void
Removes all manifolds in the map which have isDead set to true.
Returns
void
Defined in
src/physics/manifoldMap.ts:141
removeManifold
▸ removeManifold(a, b): boolean
Removes the manifold involving objects a and b.
Parameters
| Name | Type | Description |
|---|---|---|
a | CollisionObject | An object in the manifold |
b | CollisionObject | Another object in the manifold |
Returns
boolean
Wether or not a manifold was removed
Defined in
src/physics/manifoldMap.ts:116
removeManifoldsInvolving
▸ removeManifoldsInvolving(obj): void
Removes all manifolds involving the given object.
Parameters
| Name | Type | Description |
|---|---|---|
obj | CollisionObject | The obj to remove manifolds of |
Returns
void
Defined in
src/physics/manifoldMap.ts:131
