Detailed Description

A Trigger is an object that can either be active or inactive, with a specified behavior how to switch between the two.

Each time a switch occurs an Event is fired with as the originator the Trigger that caused the Event.

Triggers also allow for additional complexity which can be added through the choice of the parameters explained below: But first it is imperative to understand a small implementation detail. There is a distinction between the Trigger being triggered (there is the state triggered for that) and the Trigger being active (for that is the state activity). From the outside only the activity is visible. The state triggered tells us whether the trigger is actually triggered, but it could pretend (for some reason, some of which we will see shortly) to be active, while it in fact isn't. The standard behavior is, that the activity changes, when the Trigger transits from being triggered to being not triggered or the other way around. The parameters are:

An example of a Trigger created through XML would look like this:

<Trigger position="0,0,0" delay="1.3" switch="true" stayactive="true" activations="7" invert="true" mode="xor" broadcast="false" target="Pawn">

Constructor & Destructor Documentation

orxonox::Trigger::Trigger ( Context context)

Constructor.

Registers and initializes the object.

orxonox::Trigger::~Trigger ( )
virtual

Destructor.

Member Function Documentation

void orxonox::Trigger::changedVisibility ( void  )
virtual

React to a change of visibility of the trigger by adjusting the visibility of the debug billboards.

Reimplemented from orxonox::WorldEntity.

bool orxonox::Trigger::checkAnd ( )
private

Check whether all the sub-triggers of this Trigger are active.

This is in fact the conjunction (logical AND) of the activity of all its sub-triggers.

Returns
Returns true if all the sub-triggers of this Trigger are active, false if at least one of them is not active.
bool orxonox::Trigger::checkOr ( )
private

Check whether at least one of the sub-triggers of this Trigger is active.

This is in fact the disjunction (logical OR) of the activity of all its sub-triggers.

Returns
Returns true if at least one of the sub-triggers of this Trigger is active, false if none of them is active.
bool orxonox::Trigger::checkXor ( )
private

Check whether exactly one of the sub-triggers of this Trigger is active.

This is in fact the logical XOR of the activity of all its sub-triggers.

Returns
Returns true if exactly one of the sub-triggers of this Trigger is active, false if none of them or two or more of them are active.
void orxonox::Trigger::debugFlares ( bool  bVisible)
static

Set the visibility of all debug billboards of all Triggers.

Parameters
bVisibleThe visibility the billboards are set to.
void orxonox::Trigger::delayChanged ( void  )
virtual

React to a change in delay.

Only newly arriving states are affected by a change in delay.

Reimplemented from orxonox::TriggerBase.

bool orxonox::Trigger::isActive ( void  ) const
inlinevirtual

Check whether the Trigger is active.

Returns
Returns if the Trigger is active.

Reimplemented from orxonox::TriggerBase.

bool orxonox::Trigger::isTriggered ( )
inlineprotected

Check whether the Trigger is triggered according to its mode.

Returns
Returns true if the Trigger is triggered, false if not.
bool orxonox::Trigger::isTriggered ( TriggerMode  mode)
protectedvirtual

Check whether the Trigger should be triggered, given only its sub-triggers, given a specific mode.

Parameters
modeThe Trigger mode. Specifies how the sub-triggers are combined and how they affect the Trigger.
Returns
Returns true if the Trigger should be triggered and false if not.

Reimplemented in orxonox::DistanceTrigger, and orxonox::EventTrigger.

void orxonox::Trigger::setBillboardColour ( const ColourValue &  colour)
private

Set the colour of the debug billboard.

Parameters
colourThe colour the billboard is set to.
void orxonox::Trigger::storeState ( )
private

Stores the state in the queue.

The queue is a list of states that are waiting to take effect paired with the time it has to wait after its preceding state takes effect.

bool orxonox::Trigger::switchState ( )
private

Switch (toggle) the activity of the Trigger.

Returns
Returns true if the activity of the Trigger has changed. False if not.
void orxonox::Trigger::tick ( float  dt)
virtual
Parameters
dtThe time elapsed since last tick.

Reimplemented from orxonox::Tickable.

void orxonox::Trigger::triggered ( bool  bIsTriggered)
protectedvirtual

Fires an event with the input triggered state.

Parameters
bIsTriggeredThe triggered state.

Reimplemented in orxonox::CheckPoint.

Member Data Documentation

bool orxonox::Trigger::bActive_
private

Whether the trigger is active (to the outside triggered).

bool orxonox::Trigger::bTriggered_
private

Whether the trigger is triggered (to the inside).

BillboardSet orxonox::Trigger::debugBillboard_
private

A set of debug billboards to visualize the state of the trigger.

char orxonox::Trigger::latestState_
private

Temporarily stores a state consisting of whether the trigger is triggeres at the first bit (least significant bit) and its activity at the second bit.

float orxonox::Trigger::remainingTime_
private

The time until the next state (in the queue) takes effect.

std::queue<std::pair<float, char> > orxonox::Trigger::stateChanges_
private

A queue of state changes (in the same format as latestState_) paired with the time they will take effect since the last state change took effect.

float orxonox::Trigger::timeSinceLastEvent_
private

The time since the last event came in.
