Calculate the end position the ball will be in.

The result of this calculation is stored in this->ballEndPosition_.

void orxonox::PongAI::calculateRandomOffset ( )

protected

Calculates the random offset, that accounts for random errors the AI makes in order to be beatable.

The higher the strength of the AI, the smaller the (expected value of the) error. The result of this method is stored in this->randomOffset_.

void orxonox::PongAI::delayedMove ( )

protected

Is called, when a delayed move takes effect.

void orxonox::PongAI::move	(	char	direction,
		bool	bUseDelay
	)

protected

Determine the movement the AI will undertake.

(Either -1, 0 or 1) The result of this calculation is stored in this->movement_;

Parameters

direction	The current direction of movement.
bUseDelay	The time by which this move is delayed. (Again, to make the AI less efficient)

void orxonox::PongAI::setConfigValues ( void )

Sets config values.

void orxonox::PongAI::setPongBall ( PongBall * ball )

inline

Set the ball for the AI.

Parameters

ball	A pointer to the ball.

void orxonox::PongAI::tick ( float dt )

overridevirtual

Implements the behavior of the PongAI (i.e. its intelligence).

Is called each tick.

Implements the behavior of the PongAI (i.e. its intelligence).

Parameters

dt	The time that has elapsed since the last tick.

Reimplemented from orxonox::Tickable.
