Detailed Description

QAreaBody objects are objects that don't respond to collisions or receive any response from them, but only report collisions. An operation is not applied for them to move during physics steps, they are stationary. Unlike other body types, they have two event listeners named OnCollisionEnter and OnCollisionExit.

Member Function Documentation

◆ GetGravityFreeEnabled()

bool QAreaBody::GetGravityFreeEnabled ( )

inline

Returns whether the option to exempt objects entering the area from gravity is enabled. If enabled, it will disable both the globally defined gravity and the body-specific gravity applied to physics bodies entering the area.

◆ GetLinearForceToApply()

QVector QAreaBody::GetLinearForceToApply ( )

inline

Returns the amount of linear force to be applied to objects entering the area. If a force vector is defined, objects entering the area will be continuously subjected to this force.

◆ OnCollisionEnter()

virtual void QAreaBody::OnCollisionEnter ( QBody * collidedBody )

inlinevirtual

This event listener is triggered when any object enters the collision list of a QAreaBody for the first time.

Parameters

collidedBody The body entered to the collision list.

◆ OnCollisionExit()

virtual void QAreaBody::OnCollisionExit ( QBody * collidedBody )

inlinevirtual

This event listener is triggered when any object exits the collision list of a QAreaBody for the first time.

Parameters

collidedBody The body exited from the collision list.

◆ SetGravityFreeEnabled()

QAreaBody* QAreaBody::SetGravityFreeEnabled ( bool value )

inline

Sets whether the option to exempt objects entering the area from gravity is enabled. If enabled, it will disable both the globally defined gravity and the body-specific gravity applied to physics bodies entering the area.

Parameters

value A bool vector to set

Returns: A pointer to the body itself.

◆ SetLinearForceToApply()

QAreaBody* QAreaBody::SetLinearForceToApply ( QVector value )

inline

Sets the amount of linear force to be applied to objects entering the area. If a force vector is defined, objects entering the area will be continuously subjected to this force.

Parameters

value A force vector to set.

Returns: A pointer to the body itself.

Member Data Documentation

◆ CollisionEnterEventListener

std::function<void(QAreaBody *areaBody,QBody* collidedBody)> QAreaBody::CollisionEnterEventListener

This is the event listener callback function for the OnCollisionEnter event.

Parameters

areaBody	An area body.
collidedBody	The collided body.

◆ CollisionExitEventListener

std::function<void(QAreaBody *areaBody,QBody* collidedBody)> QAreaBody::CollisionExitEventListener

This is the event listener callback function for the OnCollisionExit event.

Parameters

areaBody	An area body.
collidedBody	The collided body.
