詳細描述

Qt3DCore::QEntity 是 Qt3DCore::QNode subclass that can aggregate several Qt3DCore::QComponent instances that will specify its behavior.

By itself a Qt3DCore::QEntity is an empty shell. The behavior of a Qt3DCore::QEntity object is defined by the Qt3DCore::QComponent objects it references. Each Qt3D backend aspect will be able to interpret and process an Entity by recognizing which components it is made up of. One aspect may decide to only process entities composed of a single Qt3DCore::QTransform component whilst another may focus on Qt3DInput::QMouseHandler .

成員函數文檔編製

QEntity:: QEntity ( QNode * parent = nullptr)

構造新的 Qt3DCore::QEntity 實例與 parent 作為父級。

`[虛擬]` QEntity:: ~QEntity ()

Destroys the instance of QEntity. The destructor is virtual.

void QEntity:: addComponent ( QComponent * comp )

Adds a new reference to the component comp .

注意： 若 Qt3DCore::QComponent has no parent, the Qt3DCore::QEntity will set itself as its parent thereby taking ownership of the component.

QComponentVector QEntity:: components () const

Returns the list of Qt3DCore::QComponent instances the entity is referencing.

QEntity *QEntity:: parentEntity () const

Returns the parent Qt3DCore::QEntity instance of this entity. If the immediate parent isn't a Qt3DCore::QEntity , this function traverses up the scene hierarchy until a parent Qt3DCore::QEntity is found. If no Qt3DCore::QEntity parent can be found, returns null.

void QEntity:: removeComponent ( QComponent * comp )

Removes the reference to comp .
