Member Function Documentation

Cleanup()

virtual void WBulletPhysics::Cleanup ( )

virtual

Frees all resources allocated by the physics engine.

Implements WPhysicsComponent.

CreateRigidBody()

virtual class WRigidBody* WBulletPhysics::CreateRigidBody ( uint32_t  ID = 0 ) const

virtual

Creates a new rigid body instance. This is equivalent to calling new WRigidBody(app, ID), so care must be taken to free the resource when done with it.

Parameters

ID	ID for the created rigid body

Returns

A newly allocated rigid body instance

Implements WPhysicsComponent.

Initialize()

virtual WError WBulletPhysics::Initialize ( bool  debug = false )

virtual

Initializes the physics engine.

Parameters

debug

If set to true, the physics will run in debug mode

Returns

Error code, see WError.h

Implements WPhysicsComponent.

RayCast()

virtual bool WBulletPhysics::RayCast ( WVector3  from, WVector3  to, W_RAYCAST_OUTPUT *  out = nullptr  )

virtual

Performs a ray cast operation on the physics objects. A ray cast operation checks if a ray segment (given to the function) intersects any geometry, as far as the physics engine is concerned.

Parameters

from	Starting point of the ray
to	End point of the ray
out	A pointer to a structure to be filled with extra output information

Returns

true if the ray intersects some geometry, false otherwise

Implements WPhysicsComponent.

SetGravity() [1/2]

virtual void WBulletPhysics::SetGravity ( float  x, float  y, float  z  )

virtual

Sets the physics gravity.

Parameters

x	Gravity on the x-axis
y	Gravity on the y-axis
z	Gravity on the z-axis

Implements WPhysicsComponent.

SetGravity() [2/2]

virtual void WBulletPhysics::SetGravity ( WVector3  gravity )

virtual

Sets the physics gravity.

Parameters

gravity

Physics gravity vector

Implements WPhysicsComponent.

SetSpeed()

virtual void WBulletPhysics::SetSpeed ( float  fSpeed )

virtual

Sets the simulation speed multiplier

Parameters

fSpeed

Speed multiplier, must be > 0 (1 is normal speed)

Implements WPhysicsComponent.

Start()

virtual void WBulletPhysics::Start ( )

virtual

Start the physics simulation.

Implements WPhysicsComponent.

Step()

virtual void WBulletPhysics::Step ( float  deltaTime )

virtual

Step the physics simulation a certain time forward.

Parameters

deltaTime

Time to step the simulation

Implements WPhysicsComponent.

Stepping()

virtual bool WBulletPhysics::Stepping ( ) const

virtual

This function must return true if called during Step(), and false otherwise

Returns

true if the physics simulation is stepping, false otherwise

Implements WPhysicsComponent.

Stop()

virtual void WBulletPhysics::Stop ( )

virtual

Stop (pause) the physics simulation.

Implements WPhysicsComponent.
