Detailed Description

This class represents an object inside the world.

Game objects only consists of hierarchical data like transformation and a list of components. You cannot derive from the game object class. To add functionality to an object you have to attach components to it. To create an object instance call CreateObject on the world. Never store a direct pointer to an object but store an ezGameObjectHandle instead.

Member Enumeration Documentation

◆ UpdateBehaviorIfStatic

enum ezGameObject::UpdateBehaviorIfStatic

strong

Defines update behavior for global transforms when changing the local transform on a static game object.

Enumerator
None	Only sets the local transform, does not update.
UpdateImmediately	Updates the hierarchy underneath the object immediately.

Member Function Documentation

◆ FindChildByName()

ezGameObject * ezGameObject::FindChildByName	(	const ezTempHashedString &	sName,
		bool	bRecursive = `true`
	)

Searches for a child object with the given name. Optionally traverses the entire hierarchy.

Test:: Needs a unit test

◆ FindChildByPath()

ezGameObject * ezGameObject::FindChildByPath ( ezStringView sPath )

Searches for a child using a path. Every path segment represents a child with a given name.

Paths are separated with single slashes: / When an empty path is given, 'this' is returned. When on any part of the path the next child cannot be found, nullptr is returned. This function expects an exact path to the destination. It does not search the full hierarchy for the next child, as SearchChildByNameSequence() does.

Test:: Needs a unit test

◆ GetActiveFlag()

EZ_ALWAYS_INLINE bool ezGameObject::GetActiveFlag ( ) const

Checks whether the 'active flag' is set on this game object. Note that this does not mean that the game object is also in an 'active state'.

See also: IsActive(), SetActiveFlag()

◆ GetStableRandomSeed()

EZ_ALWAYS_INLINE ezUInt32 ezGameObject::GetStableRandomSeed ( ) const

Returns a random value that is chosen once during object creation and remains stable even throughout serialization.

This value is intended to be used for choosing random variations of components. For instance, if a component has two different meshes it can use for variation, this seed should be used to decide which one to use.

The stable random seed can also be set from the outside, which is what the editor does, to assign a truly stable seed value. Therefore, each object placed in the editor will always have the same seed value, and objects won't change their appearance on every run of the game.

The stable seed is also propagated through prefab instances, such that every prefab instance gets a different value, but in a deterministic fashion.

◆ GetTeamID()

const ezUInt16& ezGameObject::GetTeamID ( ) const

inline

Returns the 'team ID' that was given during creation (/see ezGameObjectDesc)

It is automatically passed on to objects created by this object. This makes it possible to identify which player or team an object belongs to.

◆ GetVisibilityState()

ezVisibilityState::Enum ezGameObject::GetVisibilityState ( ezUInt32 uiNumFramesBeforeInvisible = 5 ) const

Retrieves a state describing how visible the object is.

An object may be invisible, fully visible, or indirectly visible (through shadows or reflections). This can be used to adjust the update logic of objects. An invisible object may stop updating entirely. An indirectly visible object may reduce its update rate.

Parameters

uiNumFramesBeforeInvisible Used to treat an object that was visible and just became invisible as visible for a few more frames.

◆ IsActive()

EZ_ALWAYS_INLINE bool ezGameObject::IsActive ( ) const

Checks whether this game object is in an active state.

The active state is determined by the active state of the parent game object and the 'active flag' of this game object. Only if the parent game object is active (and thus all of its parent objects as well) and this game object has the active flag set, will this game object be active.

See also: ezGameObject::SetActiveFlag(), ezComponent::IsActive()

◆ PostEventMessage()

void ezGameObject::PostEventMessage	(	ezMessage &	ref_msg,
		const ezComponent *	pSenderComponent,
		ezTime	delay,
		ezObjectMsgQueueType::Enum	queueType = `ezObjectMsgQueueType::NextFrame`
	)		const

Delivers an ezEventMessage to the closest (parent) object containing an ezEventMessageHandlerComponent.

Regular SendMessage() and PostMessage() send a message directly to the target object (and all attached components). SendMessageRecursive() and PostMessageRecursive() send a message 'down' the graph to the target object and all children.

In contrast, SendEventMessage() / PostEventMessage() bubble the message 'up' the graph. They do so by inspecting the chain of parent objects for the existence of an ezEventMessageHandlerComponent (typically a script component). If such a component is found, the message is delivered to it directly, and no other component. If it is found, but does not handle this type of message, the message is discarded and NOT tried to be delivered to anyone else.

If no such component is found in all parent objects, the message is delivered to one ezEventMessageHandlerComponent instances that is set to 'handle global events' (typically used for level-logic scripts), no matter where in the graph it resides. If multiple global event handler component exist that handle the same message type, the result is non-deterministic.

Parameters

msg	The message to deliver.
senderComponent	The component that triggered the event in the first place. May be nullptr. If not null, this information is stored in msg as ezEventMessage::m_hSenderObject and ezEventMessage::m_hSenderComponent. This information is used to pass through more contextual information for the event handler. For instance, a trigger component would pass through itself. A projectile component sending a 'take damage event' to the hit object, would also pass through itself (the projectile) such that the handling code can detect which object was responsible for the damage (and using the ezGameObject's team-ID, it can detect which player fired the projectile).
queueType	In which update phase to deliver the message.
delay	An optional delay before delivering the message.

◆ SearchForChildByNameSequence()

ezGameObject * ezGameObject::SearchForChildByNameSequence	(	ezStringView	sObjectSequence,
		const ezRTTI *	pExpectedComponent = `nullptr`
	)

Searches for a child similar to FindChildByName() but allows to search for multiple names in a sequence.

The names in the sequence are separated with slashes. For example, calling this with "a/b" will first search the entire hierarchy below this object for a child named "a". If that is found, the search continues from there for a child called "b". If such a child is found and pExpectedComponent != nullptr, it is verified that the object contains a component of that type. If it doesn't the search continues (including back-tracking).

Test:: Needs a unit test

◆ SearchForChildrenByNameSequence()

void ezGameObject::SearchForChildrenByNameSequence	(	ezStringView	sObjectSequence,
		const ezRTTI *	pExpectedComponent,
		ezHybridArray< ezGameObject *, 8 > &	out_objects
	)

Same as SearchForChildByNameSequence but returns ALL matches, in case the given path could mean multiple objects.

Test:: Needs a unit test

◆ SendEventMessage() [1/2]

bool ezGameObject::SendEventMessage	(	ezMessage &	ref_msg,
		const ezComponent *	pSenderComponent
	)

Delivers an ezEventMessage to the closest (parent) object containing an ezEventMessageHandlerComponent.

Regular SendMessage() and PostMessage() send a message directly to the target object (and all attached components). SendMessageRecursive() and PostMessageRecursive() send a message 'down' the graph to the target object and all children.

In contrast, SendEventMessage() / PostEventMessage() bubble the message 'up' the graph. They do so by inspecting the chain of parent objects for the existence of an ezEventMessageHandlerComponent (typically a script component). If such a component is found, the message is delivered to it directly, and no other component. If it is found, but does not handle this type of message, the message is discarded and NOT tried to be delivered to anyone else.

If no such component is found in all parent objects, the message is delivered to one ezEventMessageHandlerComponent instances that is set to 'handle global events' (typically used for level-logic scripts), no matter where in the graph it resides. If multiple global event handler component exist that handle the same message type, the result is non-deterministic.

Parameters

msg The message to deliver.

senderComponent The component that triggered the event in the first place. May be nullptr. If not null, this information is stored in msg as ezEventMessage::m_hSenderObject and ezEventMessage::m_hSenderComponent. This information is used to pass through more contextual information for the event handler. For instance, a trigger component would pass through itself. A projectile component sending a 'take damage event' to the hit object, would also pass through itself (the projectile) such that the handling code can detect which object was responsible for the damage (and using the ezGameObject's team-ID, it can detect which player fired the projectile).

◆ SendEventMessage() [2/2]

bool ezGameObject::SendEventMessage	(	ezMessage &	ref_msg,
		const ezComponent *	pSenderComponent
	)		const

Delivers an ezEventMessage to the closest (parent) object containing an ezEventMessageHandlerComponent.

Regular SendMessage() and PostMessage() send a message directly to the target object (and all attached components). SendMessageRecursive() and PostMessageRecursive() send a message 'down' the graph to the target object and all children.

In contrast, SendEventMessage() / PostEventMessage() bubble the message 'up' the graph. They do so by inspecting the chain of parent objects for the existence of an ezEventMessageHandlerComponent (typically a script component). If such a component is found, the message is delivered to it directly, and no other component. If it is found, but does not handle this type of message, the message is discarded and NOT tried to be delivered to anyone else.

If no such component is found in all parent objects, the message is delivered to one ezEventMessageHandlerComponent instances that is set to 'handle global events' (typically used for level-logic scripts), no matter where in the graph it resides. If multiple global event handler component exist that handle the same message type, the result is non-deterministic.

Parameters

msg The message to deliver.

senderComponent The component that triggered the event in the first place. May be nullptr. If not null, this information is stored in msg as ezEventMessage::m_hSenderObject and ezEventMessage::m_hSenderComponent. This information is used to pass through more contextual information for the event handler. For instance, a trigger component would pass through itself. A projectile component sending a 'take damage event' to the hit object, would also pass through itself (the projectile) such that the handling code can detect which object was responsible for the damage (and using the ezGameObject's team-ID, it can detect which player fired the projectile).

◆ SendMessage() [1/2]

EZ_ALWAYS_INLINE bool ezGameObject::SendMessage ( ezMessage & ref_msg )

Sends a message to all components of this object.

Returns true, if there was any recipient for this type of message.

◆ SendMessage() [2/2]

EZ_ALWAYS_INLINE bool ezGameObject::SendMessage ( ezMessage & ref_msg ) const

Sends a message to all components of this object.

Returns true, if there was any recipient for this type of message.

◆ SendMessageRecursive() [1/2]

EZ_ALWAYS_INLINE bool ezGameObject::SendMessageRecursive ( ezMessage & ref_msg )

Sends a message to all components of this object and then recursively to all children.

Returns true, if there was any recipient for this type of message.

◆ SendMessageRecursive() [2/2]

EZ_ALWAYS_INLINE bool ezGameObject::SendMessageRecursive ( ezMessage & ref_msg ) const

Sends a message to all components of this object and then recursively to all children.

Returns true, if there was any recipient for this type of message.

◆ SetActiveFlag()

void ezGameObject::SetActiveFlag ( bool bEnabled )

Sets the 'active flag' of the game object, which affects its final 'active state'.

The active flag affects the 'active state' of the game object and all its children and attached components. When a game object does not have the active flag, it is switched to 'inactive'. The same happens for all its children and all components attached to those game objects. Thus removing the active flag from a game object recursively deactivates the entire sub-tree of objects and components.

When the active flag is set on a game object, and all of its parent nodes have the flag set as well, then the active state will be set to true on it and all its children and attached components.

See also: IsActive(), ezComponent::SetActiveFlag()

◆ SetLocalPosition()

EZ_ALWAYS_INLINE void ezGameObject::SetLocalPosition ( ezVec3 vPosition )

Changes the position of the object local to its parent.

Note: The rotation of the object itself does not affect the final global position! The local position is always in the space of the parent object. If there is no parent, local position and global position are identical.

◆ SetStableRandomSeed()

EZ_ALWAYS_INLINE void ezGameObject::SetStableRandomSeed ( ezUInt32 uiSeed )

Overwrites the object's random seed value.

See GetStableRandomSeed() for details.

It should not be necessary to manually change this value, unless you want to make the seed deterministic according to a custom rule.
