Class Animation

Definition

Namespace:

Tizen.NUI

Assembly:

Tizen.NUI.dll

Animation can be used to animate the properties of any number of objects, typically view.
If the "Finished" event is connected to a member function of an object, it must be disconnected before the object is destroyed.
This is typically done in the object destructor, and requires either the animation handle to be stored.
The overall animation time is superseded by the values given in the animation time used when calling the AnimateTo(), AnimateBy(), AnimateBetween() and AnimatePath() methods.
If any of the individual calls to those functions exceeds the overall animation time (Duration), then the overall animation time is automatically extended.

Declaration

public Animation(int durationMilliSeconds)

Parameters

Type	Name	Description
int	durationMilliSeconds	The duration in milliseconds.

The progress must be in the 0-1 interval or in the play range interval if defined
otherwise, it will be ignored.

This action is performed when the animation ends or if it is stopped.
The default end action is cancel.

Declaration

public Animation.EndActions EndAction { get; set; }

Property Value

Type	Description

LoopCount

Set: Enables looping for a specified number of repeats. A zero is the same as Looping = true; i.e., repeat forever.
This property resets the looping value and should not be used with the Looping property.
Setting this parameter does not cause the animation to Play().
Get: Gets the loop count. A zero is the same as Looping = true; i.e., repeat forever.
The loop count is initially 1 for play once.

Declaration

public int LoopCount { get; set; }

Property Value

Type	Description
int

Looping

Gets or sets the status of whether the animation will loop.
This property resets the loop count and should not be used with the LoopCount property.
Setting this parameter does not cause the animation to Play().

Declaration

public bool Looping { get; set; }

Property Value

Type	Description
bool

PlayRange

Gets or sets the playing range.
Animation will play between the values specified. Both values (range.x and range.y ) should be between 0-1, otherwise they will be ignored. If the range provided is not in proper order (minimum, maximum ), it will be reordered.

Declaration

public RelativeVector2 PlayRange { get; set; }

Property Value

Type	Description
RelativeVector2

ProgressNotification

Gets or sets the progress notification marker which triggers the ProgressReachedSignal.
Percentage of animation progress should be greater than 0 and less than 1, for example, 0.3 for 30%
One notification can be set on each animation.

SpeedFactor

Gets or sets specificifications of a speed factor for the animation.
The speed factor is a multiplier of the normal velocity of the animation.
Values between [0, 1] will slow down the animation and values above one will speed up the animation.
It is also possible to specify a negative multiplier to play the animation in reverse.

Declaration

public float SpeedFactor { get; set; }

Property Value

Type	Description
float

State

Queries the state of the animation.

Declaration

public Animation.States State { get; }
