Member Function Documentation

◆ Deinitialize()

void ezTypeScriptComponent::Deinitialize ( )
overrideprotectedvirtual

This method is called before the component is destroyed. A derived type can override this method to do common de-initialization work.

This function is always called before destruction, even if the component is currently not active. The default implementation checks whether the component is currently active and will ensure OnDeactivated() gets called if necessary. For typical game code, prefer to use OnDeactivated().

See also
OnActivated(), OnDeactivated(), Initialize(), Deinitialize(), OnSimulationStarted()

Reimplemented from ezEventMessageHandlerComponent.

◆ DeserializeComponent()

void ezTypeScriptComponent::DeserializeComponent ( ezWorldReader inout_stream)
overrideprotectedvirtual

Override this to load the current state of the component from the given stream.

The active state will be automatically serialized. The 'initialized' state is not serialized, all components will be initialized after creation, even if they were already in an initialized state when they were serialized.

Reimplemented from ezEventMessageHandlerComponent.

◆ Initialize()

void ezTypeScriptComponent::Initialize ( )
overrideprotectedvirtual

Can be overridden for basic initialization that depends on a valid hierarchy and position.

All trivial initialization should be done in the constructor. For typical game code, you should prefer to use OnSimulationStarted(). This method is called once for every component, after creation but only at the start of the next world update. Therefore the global position has already been computed and the owner ezGameObject is set. Contrary to OnActivated() and OnSimulationStarted(), this function is always called for all components.

See also
OnActivated(), OnDeactivated(), Initialize(), Deinitialize(), OnSimulationStarted()

Reimplemented from ezComponent.

◆ OnActivated()

void ezTypeScriptComponent::OnActivated ( )
overrideprotectedvirtual

This method is called when the component gets activated.

By default a component is active, but it can be created in an inactive state. In such a case OnActivated() is only called once a component is activated. If a component gets switched between active and inactive at runtime, OnActivated() and OnDeactivated() are called accordingly. In contrast Initialize() and Deinitialize() are only ever called once.

OnActivated(), OnDeactivated(), Initialize(), Deinitialize(), OnSimulationStarted()

Reimplemented from ezComponent.

◆ OnDeactivated()

void ezTypeScriptComponent::OnDeactivated ( )
overrideprotectedvirtual

This method is called when the component gets deactivated.

Upon destruction, a component that is active first gets deactivated. Therefore OnDeactivated() should be used for typical game code cleanup.

See also
OnActivated(), OnDeactivated(), Initialize(), Deinitialize(), OnSimulationStarted()

Reimplemented from ezComponent.

◆ OnSimulationStarted()

void ezTypeScriptComponent::OnSimulationStarted ( )
overrideprotectedvirtual

This method is called once for active components, at the start of the next world update, but only when the world is simulated.

This is the one preferred method to setup typical game logic. In a pure game environment there is no practical difference between OnActivated() and OnSimulationStarted(), as OnSimulationStarted() will be called right after OnActivated().

However, when a scene is open inside the editor, there is an important difference: OnActivated() is called once the component was created. OnSimulationStarted() is only called once the game simulation is started inside the editor. As an example, if a component starts a sound in OnActivated(), that sound will play right after the scene has been loaded into the editor. If instead the sound gets started in OnSimulationStarted(), it will only play once the user starts the game mode inside the editor.

Additionally, OnSimulationStarted() is only executed once, even if the ezWorld pauses and resumes world simulation multiple times. However, note that it will be called again after the component has been deactivated and is activated again.

◆ OnUnhandledMessage() [1/2]

bool ezTypeScriptComponent::OnUnhandledMessage ( ezMessage msg,
bool  bWasPostedMsg 
) const
overrideprotectedvirtual

When EnableUnhandledMessageHandler() was activated, this is called for all messages for which there is no dedicated message handler.

Returns
Should return true if the given message was handled, false otherwise.

Reimplemented from ezComponent.

◆ OnUnhandledMessage() [2/2]

bool ezTypeScriptComponent::OnUnhandledMessage ( ezMessage msg,
bool  bWasPostedMsg 
)
overrideprotectedvirtual

When EnableUnhandledMessageHandler() was activated, this is called for all messages for which there is no dedicated message handler.

Returns
Should return true if the given message was handled, false otherwise.
