QLerpClipBlend Class

  • Header: QLerpClipBlend

  • Since: Qt 5.9

  • CMake:

    find_package(Qt6 REQUIRED COMPONENTS 3danimation)

    target_link_libraries(mytarget PRIVATE Qt6::3danimation)

  • qmake: QT += 3danimation

  • Inherited By:

  • Instantiated By: qml-qt3d-animation-lerpclipblend.xml

  • Inherits: Qt3DAnimation::QAbstractClipBlendNode

Detailed Description

QLerpClipBlend can be useful to create advanced animation effects based on individual animation clips. For instance, given a player character, lerp blending could be used to combine a walking animation clip with an injured animation clip based on a blend factor that increases the more the player gets injured. This would then allow with blend factor == 0 to have a non injured walking player, with blend factor == 1 a fully injured player, with blend factor == 0.5 a partially walking and injured player.

Property Documentation

 

blendFactor : float

Specifies the blending factor between 0 and 1 to control the blending of two animation clips.

Access functions:

  • float blendFactor() const

  • void setBlendFactor(float blendFactor)

Notifier signal:

  • void blendFactorChanged(float blendFactor)

endClip : Qt3DAnimation::QAbstractClipBlendNode*

Holds the sub-tree that should be used as the start clip for this lerp blend node. That is, the clip returned by this blend node when the blendFactor is set to a value of 1.

Access functions:

  • *endClip() const

  • void setEndClip( *endClip)

Notifier signal:

  • void endClipChanged( *endClip)

startClip : Qt3DAnimation::QAbstractClipBlendNode*

Holds the sub-tree that should be used as the start clip for this lerp blend node. That is, the clip returned by this blend node when the blendFactor is set to a value of 0.

Access functions:

  • *startClip() const

  • void setStartClip( *startClip)

Notifier signal:

  • void startClipChanged( *startClip)
