\qmltype Behavior
\brief Technology Preview Behavior Integration
This is a technology preview (API may change in upcoming version) of how
Qt 3D Studio could support writing custom behavior scripts using QML and
JavaScript. It enables interacting with the runtime using the Behavior
QML class exposed to each behavior script.
In QML behavior script, the integration to Qt 3D Studio is established by using
the metadata tag system similar to the \l {file-formats-effects.html}{effect}
and \l {file-formats-material.html}{material} files.
\badcode
[[
<Property name="somePropertyName" ... />
<Handler name="someHandlerName" ... />
<Event name="onSomeEvent" ... />
...
]]
\endcode
Secondly, the QML behavior script needs access to the QML module.
\badcode
import QtStudio3D.Behavior 1.0
\endcode
Finally, the Behavior type needs to be implemented in the qml script.
\badcode
Behavior {
id: mybehavior
function onInitialize() {
...
}
function onActivate() {
...
}
function onUpdate() {
...
}
function onDeactivate() {
...
}
function someHandlerName() {
...
fireEvent("onSomeEvent")
}
}
\endcode
*/
/*!
\qmlmethod float Behavior::getDeltaTime()
Returns the delta time between this and previous frame in milliseconds.
*/
/*!
\qmlmethod float Behavior::getAttribute(string attribute)
Returns the value of the given \a attribute.
*/
/*!
\qmlmethod void Behavior::setAttribute(string attribute, var value)
Sets the \a value of the given \a attribute.
*/
/*!
\qmlmethod void Behavior::setAttribute(string handle, string attribute, var value)
Sets the \a value of the given \a attribute for a given \a handle.
*/
/*!
\qmlmethod void Behavior::fireEvent(string event)
Fires the given \a event.
*/
/*!
\qmlmethod void Behavior::registerForEvent(string event, QJSValue function)
Registers the script for an \a event with the handler \a function.
*/
/*!
\qmlmethod void Behavior::registerForEvent(string handle, string event, QJSValue function)
Registers the script for an \a event with the handler \a function for a given \a handle.
*/

Unregisters the script from an \a event.
*/
/*!
\qmlmethod void Behavior::unregisterForEvent(string handle, string event)
Unregisters the script from an \a event for a given \a handle.
*/
/*!
\qmlmethod vector2d Behavior::getMousePosition()
Returns the current position of the mouse in presentation coordinates.
*/
/*!
\qmlmethod matrix4 Behavior::calculateGlobalTransform(string handle)
Returns the current global transformation of the element specified by the
\a handle or parent element if the handle is empty string.
*/
/*!
\qmlmethod vector3d Behavior::lookAt(vector3d target)
Returns the rotation angles of the look at \a target.
*/
/*!
\qmlmethod string Behavior::getParent(string handle)
Returns the parent of the given \a handle or parent element if the handle is
empty string.
*/
/*!
\qmlmethod vector3d Behavior::matrixToEuler(matrix4 matrix)
Returns the euler angles extracted from the \a matrix rotations.
*/
/*!
\qmlsignal void Behavior::onInitialize()
This signal is emitted when the script becomes active the first time.
If multiple behaviors match this, the signal for parent elements will
occur before their children/descendants. \note Each behavior will
only have its \c{onInitialize} signaled once, even if it is deactivated and
later reactivated.
*/
/*!
\qmlsignal void Behavior::onActivate()
This signal is emitted when the script becomes active.
Any behaviors which were not active last frame that are active
this frame will have their \c{onActivate} signaled. If
multiple behaviors match this, the signal for parent elements will
occur before their descendants.
*/
/*!
\qmlsignal void Behavior::onDeactivate()
This signal is emitted when the script becomes inactive.
Any behaviors which were active last frame that are not active
this frame will have their \c{onDeactivate} signaled. If
multiple behaviors match this, the signal for parent elements will
occur before their descendants.
*/
/*!
\qmlsignal void Behavior::onUpdate()
This signal is emitted on each frame when the script is active.
Any behaviors that are active this frame will have their
\c{onUpdate} signaled. If multiple behaviors match this, the signal
for parent elements will occur before their descendants.
