void Mezzanine::Physics::PhysicsManager::RemoveCollision

(

Physics::Collision *

Col)

Removes an existing collision from the world.

Remarks

In general it's not a great idea to call on this manually, but there are some situations where you would. Mostly this function exists to facilitate removal of objects from the world before the simulation ends. In such cases you have to clean up traces of the collision.

Parameters

Col	The collision to be removed.

Definition at line 985 of file physicsmanager.cpp.

void Mezzanine::Physics::PhysicsManager::RemoveCollisionsContainingProxy

(

CollidableProxy *

Proxy)

Removes all stored collisions that involve the specified CollidableProxy.

Parameters

Proxy

The Proxy which will have all of it's collisions removed.

Definition at line 999 of file physicsmanager.cpp.

void Mezzanine::Physics::PhysicsManager::RemoveConstraint

(

Physics::Constraint *

Con)

Removes a constraint from the world.

Removes a constraint from the world so that it will have no effect.

Parameters

Con	The constraint to be removed.

Definition at line 898 of file physicsmanager.cpp.

void Mezzanine::Physics::PhysicsManager::RemoveWorldTrigger

(

WorldTrigger *

Trig)

Removes a trigger from the world.

Removes a trigger from the world so that it will have no effect.

Parameters

Trig	The trigger to be removed.

Definition at line 951 of file physicsmanager.cpp.

void Mezzanine::Physics::PhysicsManager::ResetPhysicsWorld

(

ManagerConstructionInfo *

Info = 0)

Resets all the internal physics structures in this manager.

Warning

This should only be called while the world is emtpy and objects have be unloaded from it.

Parameters

Info	If you want to change the configuration of the world when restarting, you can optionally provide a new set of parameters to build the world with.

Definition at line 1069 of file physicsmanager.cpp.

void Mezzanine::Physics::PhysicsManager::SetDebugRenderingMode

(

const Integer

DebugRenderingMode)

Enables and Disables Physics Debug Drawing.

Enables and Disables Physics Debug Drawing using default wireframes. This will force renderings that match the physics subsytem pixel for pixel.

Parameters

DebugRenderingMode

1 to turn it on, 0 to turn it off. There may be other options in the future, to enable fine tuned control

Definition at line 1053 of file physicsmanager.cpp.

void Mezzanine::Physics::PhysicsManager::SetSimulationSubstepModifier

(

const Whole &

Modifier)

Sets the modifier to be used when stepping the physics simulation.

Remarks

For the most part, the simulation tick is determined by your target framerate set on Mezzanine::World. However there are some occasions when you will want to have it tick more often, in particular with sensative simulation setups involving many constraints, or small objects, or fast moving objects, or any combination of those. In order to make your simulation more stable you have to tick in smaller intervals, making it less likely for the engine to miss something or become unstable. When you pass in a modifier it'll ensure it ticks faster by that amount. For example, if you pass in 2 to this as the modifier, the physics simulation will take 2 smaller steps (the time being based on the target framerate) instead of one big one during the course of one frame.

Parameters

Modifier

The amount of substeps per frame to perform.

Definition at line 1107 of file physicsmanager.cpp.

void Mezzanine::Physics::PhysicsManager::SetWorldGravity

(

const Vector3 &

pgrav)

Sets the gravity.

Sets the strength and direction of gravity within the world.

Parameters

pgrav

Vector3 representing the strength and direction of gravity.

Definition at line 774 of file physicsmanager.cpp.

void Mezzanine::Physics::PhysicsManager::SetWorldSoftGravity

(

const Vector3 &

sgrav)

Sets the gravity for soft bodies.

Gravity for soft bodies is stored separately from rigid bodies. So if you plan to use soft bodies in your game/simulation you need to call this function otherwise they won't fall.

Parameters

sgrav

Vector3 representing the strength and direction of gravity.

Definition at line 785 of file physicsmanager.cpp.

bool Mezzanine::Physics::PhysicsManager::SimulationIsPaused

(

)

Gets Whether or not the simulation is currently paused.

Returns

Returns whether or not the simulation is paused.

Definition at line 766 of file physicsmanager.cpp.
