Member Function Documentation

ConfirmFrame()

void game::RollbackManager::ConfirmFrame	(	Frame	newValidatedFrame,
		const std::array< PhysicsState, maxPlayerNmb > &	serverPhysicsState
	)

ConfirmFrame is a method that confirms the new validate frame by checking the Physics State checksums It is called by the clients when receiving Confirm Frame packet.

Parameters

newValidatedFrame	is the new frame that is validated
serverPhysicsState	is the physics state given by the server through a packet

DestroyEntity()

void game::RollbackManager::DestroyEntity

(

core::Entity

entity

)

DestroyEntity is a method that does not destroy the entity definitely, but puts the DESTROY flag on. An entity is truly destroyed when the destroy frame is validated.

Parameters

entity

is the entity to be "destroyed"

OnTrigger()

void game::RollbackManager::OnTrigger ( core::Entity  entity1, core::Entity  entity2  )

overridevirtual

Implements game::OnTriggerInterface.

SetPlayerInput()

void game::RollbackManager::SetPlayerInput	(	PlayerNumber	playerNumber,
		PlayerInput	playerInput,
		Frame	inputFrame
	)

SetPlayerInput is a method that set the input of a certain player on a certain game frame. It can change an input between the last validated frame and the current frame. It is called by the GameManager when receiving new inputs from packets.

Parameters

playerNumber	is the player number whose input will change
playerInput	is the new input
inputFrame	is the game frame of the new input

ValidateFrame()

void game::RollbackManager::ValidateFrame

(

Frame

newValidateFrame

)

ValidateFrame is a method that validates all the frames from lastValidateFrame_ to newValidateFrame. It changes lastValidateFrame_ to be newValidateFrame.

Parameters

newValidateFrame

is the new value of lastValidateFrame_
