Properties

Property	Description
Components	The Shapes that make up the PhysicsEntity's collider.
Position	The position of the PhysicsEntity (the center of its first Shape component).
Mass	The mass of the PhysicsEntity.
InvMass
Inertia	The inertia of the PhysicsEntity, calculated from mass.
InvInertia
Velocity	The velocity of the PhysicsEntity.
Acceleration	The acceleration of the PhysicsEntity.
Speed	The speed multiplier applied to acceleration when the PhysicsEntity moves.
Friction	The friction of the PhysicsEntity.
AngleSpeed	The speed at which the PhysicsEntity is currently rotating.
AngleFriction	The friction of the PhysicsEntity's rotation.
Elasticity	The elasticity of the PhysicsEntity when a collision is resolved.
Trigger	Determines if the PhysicsEntity is a trigger. Collisions with triggers will not be resolved, but will still be registered.
BodyColor	The color to render the PhysicsEntity's Shape components when visualizing bodies.
Colliding

Constructors

public `PhysicsEntity`

public PhysicsEntity(RenderObject sprite, Vec2 position, float width, float height, float mass) : base(sprite, position, (int)width, (int)height)

Initialize a new PhysicsEntity. By default, it will have a mass but no Components. In most cases, it is more appropriate to use an extension like a BallEntity or BoxEntity.

Parameter	Description
RenderObject `sprite`
Vec2 `position`
float `width`
float `height`
float `mass`

Methods

void `Move`

public virtual void Move()

Perform physics movement for the Body.

List `GetColliding`

public List<TPhysicsEntity> GetColliding<TPhysicsEntity>(bool includeTriggers = true, bool includeSolids = true) where TPhysicsEntity : PhysicsEntity

Get a list of all PhysicsEntities of a given type currently colliding with this Entity.

Returns: A list of all PhyiscsEntities currently colliding with this one.

Type Parameter	Description
`TPhysicsEntity`	The type of PhysicsEntity to check for.

Parameter	Description
bool `includeTriggers` = `true`	Include PhysicsEntities that are triggers.
bool `includeSolids` = `true`	Include PhysicsEntities that are not triggers.

List `GetColliding`

public List<PhysicsEntity> GetColliding(bool includeTriggers = true, bool includeSolids = true)

Get a list of all PhysicsEntities currently colliding with this Entity.

Returns: A list of all PhysicsEntities currently colliding with this one.

Parameter	Description
bool `includeTriggers` = `true`	Include PhysicsEntities that are triggers.
bool `includeSolids` = `true`	Include PhysicsEntities that are not triggers.

void `DrawBody`

public virtual void DrawBody(SpriteBatch spriteBatch)

Visualize the Components of the Body according to the BodyColor. The default implementation is only intended for debug purposes as some draw calls, particularly for Circles are highly inefficient.
