平行讀取

The Animation object that was used to create this AnimationTrack. To create an AnimationTrack, you must load an Animation object onto an AnimationController using the Animator:LoadAnimation() method.

範例程式碼

Listen For New Animations
local function listenForNewAnimations(humanoid)

	humanoid.AnimationPlayed:Connect(function(animationTrack)

		local animationName = animationTrack.Animation.Name

		print("Animation playing " .. animationName)

	end)

end



local humanoid = script.Parent:WaitForChild("Humanoid")



listenForNewAnimations(humanoid)

IsPlaying

bool
唯讀
未複製
平行讀取

A read only property that returns true when the AnimationTrack is playing.

This property can be used by developers to check if an animation is already playing before playing it (as that would cause it to restart). If a developer wishes to obtain all playing AnimationTracks on a Humanoid or AnimationController they should use Humanoid:GetPlayingAnimationTracks()

範例程式碼

AnimationTrack IsPlaying
local function playOrAdjust(animationTrack, fadeTime, weight, speed)

	if not animationTrack.IsPlaying then

		animationTrack:Play(fadeTime, weight, speed)

	else

		animationTrack:AdjustSpeed(speed)

		animationTrack:AdjustWeight(weight, fadeTime)

	end

end



local animation = Instance.new("Animation")

animation.AnimationId = "rbxassetid://507765644"



local humanoid = script.Parent:WaitForChild("Humanoid")

local animator = humanoid:WaitForChild("Animator")

local animationTrack = animator:LoadAnimation(animation)



playOrAdjust(animationTrack, 1, 0.6, 1)

Length

number
唯讀
未複製
平行讀取

A read only property that returns the length (in seconds) of an AnimationTrack. This will return 0 until the animation has fully loaded and thus may not be immediately available.

When the AnimationTrack.Speed of an AnimationTrack is equal to 1, the animation will take AnimationTrack.Length (in seconds) to complete.

animation.AnimationId = "rbxassetid://507765000"



local humanoid = script.Parent:WaitForChild("Humanoid")

local animator = humanoid:WaitForChild("Animator")



local animationTrack = animator:LoadAnimation(animation)



playAnimationForDuration(animationTrack, 3)

Looped

bool
平行讀取

This property sets whether the animation will repeat after finishing. If it is changed while playing the result will take effect after the animation finishes.

The Looped property for AnimationTrack defaults to how it was set in the animation editor. However this property can be changed, allowing control over the AnimationTrack while the game is running. Looped also correctly handles animations played in reverse (negative AnimationTrack.Speed). After the first keyframe is reached, it will restart at the last keyframe.

This property allows the developer to have a looping and non looping variant of the same animation, without needing to upload two versions to Roblox.

Priority

Enum.AnimationPriority
平行讀取

This property sets the priority of an AnimationTrack. Depending on what this is set to, playing multiple animations at once will look to this property to figure out which Keyframe Poses should be played over one another.

The Priority property for AnimationTrack defaults to how it was set and published from Studio's Animation Editor. It uses Enum.AnimationPriority which has 7 priority levels:

  1. Action4 (highest priority)
  2. Action3
  3. Action2
  4. Action
  5. Movement
  6. Idle
  7. Core (lowest priority)

Properly set animation priorities, either through the editor or through this property, allow multiple animations to be played without them clashing. Where two playing animations direct the target to move the same limb in different ways, the AnimationTrack with the highest priority will show. If both animations have the same priority, the weights of the tracks will be used to combine the animations.

This property also allows the developer to play the same animation at different priorities, without needing to upload additional versions to Roblox.

Speed

number
唯讀
未複製
平行讀取

The Speed of an AnimationTrack is a read only property that gives the current playback speed of the AnimationTrack. This has a default value of 1. When speed is equal to 1, the amount of time an animation takes to complete is equal to AnimationTrack.Length (in seconds).

If the speed is adjusted, then the actual time it will take a track to play can be computed by dividing the length by the speed. Speed is a unitless quantity.

Speed can be used to link the length of an animation to different game events (for example recharging an ability) without having to upload different variants of the same animation.

This property is read only, and you can change it using AnimationTrack:AdjustSpeed().

TimePosition

number
未複製
平行讀取

Returns the position in time in seconds that an AnimationTrack is through playing its source animation. Can be set to make the track jump to a specific moment in the animation.

TimePosition can be set to go to a specific point in the animation, but the AnimationTrack must be playing to do so. It can also be used in combination with AnimationTrack:AdjustSpeed() to freeze the animation at a desired point (by setting speed to 0).

範例程式碼

WeightCurrent

number
唯讀
未複製
平行讀取

When weight is set in an AnimationTrack it does not change instantaneously but moves from WeightCurrent to AnimationTrack.WeightTarget. The time it takes to do this is determined by the fadeTime parameter given when the animation is played, or the weight is adjusted.

WeightCurrent can be checked against AnimationTrack.WeightTarget to see if the desired weight has been reached. Note that these values should not be checked for equality with the == operator, as both of these values are floats. To see if WeightCurrent has reached the target weight, it is recommended to see if the distance between those values is sufficiently small (see code sample below).

The animation weighting system is used to determine how AnimationTracks playing at the same priority are blended together. The default weight is one, and no movement will be visible on an AnimationTrack with a weight of zero. The pose that is shown at any point in time is determined by the weighted average of all the Poses and the WeightCurrent of each AnimationTrack. In most cases blending animations is not required and using AnimationTrack.Priority is more suitable.

WeightTarget

number
唯讀
未複製
平行讀取

AnimationTrack.WeightTarget is a read-only property that gives the current weight of the AnimationTrack. It has a default value of 1 and is set when AnimationTrack:Play(), AnimationTrack:Stop() or AnimationTrack:AdjustWeight() is called. When weight is set in an AnimationTrack it does not change instantaneously but moves from WeightCurrent to AnimationTrack.WeightTarget. The time it takes to do this is determined by the fadeTime parameter given when the animation is played, or the weight is adjusted.

WeightCurrent can be checked against AnimationTrack.WeightTarget to see if the desired weight has been reached. Note that these values should not be checked for equality with the == operator, as both of these values are floats. To see if WeightCurrent has reached the target weight, it is recommended to see if the distance between those values is sufficiently small (see code sample below).

方法

AdjustSpeed

void

This function changes the AnimationTrack.Speed of an animation. A positive value for speed plays the animation forward, a negative one plays it backwards, and 0 pauses it.

An AnimationTrack's initial speed is set as a parameter in AnimationTrack:Play(). However a track's Speed can be changed during playback, using AdjustSpeed. When speed is equal to 1, the amount of time an animation takes to complete is equal to AnimationTrack.Length (in seconds).

When is adjusted, then the actual time it will take a track to play can be computed by dividing the length by the speed. Speed is a unitless quantity.

Speed can be used to link the length of an animation to different gameplay events (for example recharging an ability) without having to upload different variants of the same animation.

AdjustWeight

void

Changes the weight of an animation, with the optional fadeTime parameter determining how long it takes for AnimationTrack.WeightCurrent to reach AnimationTrack.WeightTarget.

When weight is set in an AnimationTrack it does not change instantaneously but moves from WeightCurrent to AnimationTrack.WeightTarget. The time it takes to do this is determined by the fadeTime parameter given when the animation is played, or the weight is adjusted.

WeightCurrent can be checked against AnimationTrack.WeightTarget to see if the desired weight has been reached. Note that these values should not be checked for equality with the == operator, as both of these values are floats. To see if WeightCurrent has reached the target weight, it is recommended to see if the distance between those values is sufficiently small (see code sample below).

The default weight is one, and no movement will be visible on an AnimationTrack with a weight of zero. The pose that is shown at any point in time is determined by the weighted average of all the Poses and the WeightCurrent of each AnimationTrack. See below for an example of animation blending in practice. In most cases blending animations is not required and using AnimationTrack.Priority is more suitable.

GetMarkerReachedSignal

RBXScriptSignal

This function returns an event similar to the AnimationTrack.KeyframeReached event, except it only fires when a specified KeyframeMarker has been hit in an animation. The difference allows for greater control of when the event will fire.

To learn more about using this function, see Animation Events in the Animation Editor article.

More About Keyframes

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.

Keyframe names do not need to be unique. For example, if an Animation has three keyframes named "EmitParticles," the connected event returned by this function will fire each time one of these keyframes is reached.

See also:

參數

name: string

The name of the KeyFrameMarker the signal is being created for.

GetTimeOfKeyframe

number

Returns the time position of the first Keyframe of the given name in an AnimationTrack. If multiple Keyframes share the same name, it will return the earliest one in the animation.

This function will return an error if it is uses with an invalid keyframe name (one that does not exist for example) or if the underlying Animation has not yet loaded. To address this make sure only correct keyframe names are used and the animation has loaded before calling this function.

To check if the animation has loaded, verify that the AnimationTrack.Length is greater than zero.

Play

void

When AnimationTrack:Play() is called the track's animation will begin playing and the weight of the animation will increase from 0 to the specified weight (defaults to 1) over the specified fadeTime (defaults to 0.1).

The speed the AnimationTrack will play at is determined by the speed parameter (defaults to 1). When the speed is equal to 1 the number of seconds the track will take to complete is equal to the track's AnimationTrack.Length property. For example, a speed of 2 will cause the track to play twice as fast.

The weight and speed of the animation can also be changed after the animation has begun playing by using the AnimationTrack:AdjustWeight() and AnimationTrack:AdjustSpeed() methods.

If the developer wants to start the animation at a specific point using AnimationTrack.TimePosition, it is important the animation is played before this is done.

Stop

void

Stops the AnimationTrack. Once called playback of the AnimationTrack will stop and the weight of the animation will move towards zero over a length of time specified by the optional fadeTime parameter.

For example, if Stop is called with a fadeTime of 2 seconds it will take two seconds for the weight of the AnimationTrack to reach zero and its effects completely end. Please note this will be the case regardless of the initial weight of the animation.

It is not recommended to use a fadeTime of 0 seconds to try to override this effect and end the animation immediately as presently, this causes the AnimationTrack poses to freeze.

KeyframeReached

Fires every time playback of an AnimationTrack reaches a Keyframe that does not have the default name - "Keyframe."

This event allows a developer to run code at predefined points in an animation (set by Keyframe names). This allows the default functionality of Roblox animations to be expanded upon by adding Sounds or ParticleEffects at different points in an animation.

Keyframe names do not need to be unique. For example, if an Animation has three keyframes named "Particles" the KeyframeReached event 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.

參數

keyframeName: string

The name of the Keyframe reached.


Stopped

Fires whenever the AnimationTrack finishes playing.

This event has a number of uses. It can be used to wait until an AnimationTrack has stopped before continuing (for example, if chaining a series of animations to play after each other). It can also be used to clean up any Instances created during the animation playback.
