A Keyframe holds the Poses applied to joints in a Model at a given point of time in an animation. Keyframes are interpolated between during animation playback.

Note, in most cases developers do not need to manipulate KeyframeSequences as the animation editor covers most animation functionality. However, in some cases a developer may wish to generate an animation from a Script or build their own plugin.

Structure

Keyframes are held within a KeyframeSequence and contain Pose objects. The poses are named in accordance with the BaseParts they correspond to and are structured in terms of joint hierarchy. This means each Pose is parented to the Pose corresponding to the part it is attached to. See below for a visual example.

Note, as Poses are named in accordance with the BaseParts they correspond to, animations require distinct part names to play correctly.

Interpolation

During animation playback the poses in different keyframes are interpolated between. This allows a smooth animation to be created without needing to define every frame. Note, the style of interpolation is determined in the Pose object. The Keyframe object merely holds the Poses at a defined point of time in the animation (Keyframe.Time).

Özet

Özellikler

  • Time:number
    Paralel oku

    The Keyframe time position (in seconds) in an animation. This determines the time at which the Poses inside the keyframe will be shown.

Time

number
Paralel oku

This property gives the Keyframe time position (in seconds) in an animation. This determines the time at which the Poses inside the keyframe will be shown.

Note the Keyframe with the highest time value in a KeyframeSequence is used to determine the length of the animation.

		if keyframe.Time > length then

			length = keyframe.Time

AddMarker

void

This function adds a KeyframeMarker to the Keyframe by parenting it to the keyframe. It is functionally identical to setting the marker's Instance.Parent to the Keyframe.

Note, this function will not error when an instance other than a KeyframeMarker is given as the parameter and will parent it successfully.

More about Keyframes

Keyframe names do not need to be unique. For example, if an Animation has three keyframes named "Particles" the connected event returned by AnimationTrack:GetMarkerReachedSignal() will fire each time one of these keyframes is reached.

Keyframe names can be set in the Roblox Animation Editor when creating or editing an animation. They cannot however be set by a Script on an existing animation prior to playing it.
