3D shake

Shake 3D objects with translation and rotation.

Behavior properties

  • Frequency (🔢 Number). Default value is 5.
  • Start to shake at the object creation (🔘 Boolean). Default value is false.
  • Rotation amplitude around X axis (🔢 Number, Angle). Default value is 5.
  • Rotation amplitude around Y axis (🔢 Number, Angle). Default value is 5.
  • Rotation amplitude around Z axis (🔢 Number, Angle). Default value is 5.
  • Translation amplitude on X axis (🔢 Number, Distance). Default value is 0.
  • Translation amplitude on Y axis (🔢 Number, Distance). Default value is 0.
  • Translation amplitude on Z axis (🔢 Number, Distance). Default value is 0.
See internal technical details
  • Frequency is stored as Frequency (Number). Default value is 5.

  • Start to shake at the object creation is stored as IsStartingAtCreation (Boolean). Default value is false.

    This behavior must be used on an object also having a behavior with type "Scene3D::Base3DBehavior". This is stored on property Object3D.

  • Rotation amplitude around X axis is stored as RotationAmplitudeX (Number). Unit is DegreeAngle. Default value is 5.

  • Rotation amplitude around Y axis is stored as RotationAmplitudeY (Number). Unit is DegreeAngle. Default value is 5.
  • Rotation amplitude around Z axis is stored as RotationAmplitudeZ (Number). Unit is DegreeAngle. Default value is 5.
  • Translation amplitude on X axis is stored as TranslationAmplitudeX (Number). Unit is Pixel. Default value is 0.
  • Translation amplitude on Y axis is stored as TranslationAmplitudeY (Number). Unit is Pixel. Default value is 0.
  • Translation amplitude on Z axis is stored as TranslationAmplitudeZ (Number). Unit is Pixel. Default value is 0.
