Flash what is a tween

In a Motion Tween you move the small red rectangle at the top of the timeline, the shuttle, to the location where you want to change tween properties. Let's move the shuttle to frame Next hold down the Shift key and click and drag the ball to the bottom of the visible stage holding the shift key ensures that we will drag the ball in a straight line.

Next move the shuttle to frame 30 and shift-drag the ball back to the top of the screen. Notice the green motion path created where the ball will travel. The animation works, however, it lacks a realistic feeling since it moves up and down constantly at the same speed; what we want to do now is to add some real-life ingredients; when a ball hits the ground in real life, it will squeeze and squash. This adds a small black dot to the frame and saves the scale of the symbol at that frame.

Do the same thing for frame Finally, move the shuttle to frame 15 again, select the Free Transform Tool from the toolbar and squeeze the ball a bit at the top and stretch the ball a bit at the sides. Simple easing can be done by clicking on the tween and adjusting the Ease in the property tab.

If we had seperated this into two tweens, we could have set one to ease in and one to ease out. However, we want one tween to both ease in and ease out. Select the Motion Editor tab next to the Timeline tab.

Make sure that the scale indicates 30 the red box in the lower left below. Click where is says '2-Custom' to expand the graph. Click the left control point, grab the handlebar and move it along the x-axis.

Then click the right control point, grab its handlebar and move it so it is along the x-axis like below. Finally, scroll up in the Motion Editor to where it says 'Basic Motion' and in the drop-down select '2-Custom' to indicate that we want our custom ease applied to the motion. Nesting means to place all the compositional element in one of your animation sequence into a single symbol; It is an incredibly powerful technique for animators.

Let me show you how it works in this tutorial; first, let us select all the frames on the timeline of your bouncing ball animation;.

Create a new symbol named bouncingGR you can use anything you want , select Graphic as its type and click OK;. Double click on the new symbol in the Library, right-click on the timeline if there is no frame on timeline, simply press F6 to insert a frame and select Paste Frames;. Now we can delete everything on the scene1's timeline since the animation has been pasted into a symbol; then let us drag the symbol bouncingGR to the stage; On frame 1, move the symbol all the way to the left of the canvas; next, click on frame 90, press F6 then move the symbol all the way from the left to the right of the stage; finally, let us create a motion tween between this two frames, then you will see the bouncing ball is now bouncing across the screen.

In Flash CS3, not only that we can copy frames, we can also copy motions. Copy motions allows you to apply the same motion to a complete different object.

Drag the crazybunny graphic symbol to the stage or if you have not imported it yet, just import the crazybunny. Now this bunny is doing exactly the same thing as the bouncing ball you just animated; Copy motion is a very simple technique but it is a huge time saver.

Note that the green line which appeared when we first moved our symbol after creating the motion tween is its motion path. The motion path is editable like any line. Click either end of the line to begin editing both should be in the same place with our ball and now you can drag the control points to make the ball move anywhere on the screen.

Here we are going to create a few animations using motion tweens in Flash. The finished file is in the source file masking.

Here Katherine Ulrich discusses the two ways Flash mitigates both problems with a process called tweening.

What is a tween animation? Inbetweening or tweening is a key process in all types of animation, including computer animation. It is the process of generating intermediate frames between two images, called key frames, to give the appearance that the first image evolves smoothly into the second image.

How do I make a motion tween in Animate CC? Creating a motion tween animation Create a graphic or instance that you want to tween, and then right-click a frame and select Create Motion Tween.

How do you spin something in an animation? Rotate and skew objects by dragging Select the object or objects on the Stage. Do one of the following: Drag a corner handle to rotate the object.

Drag a center handle to skew the object. To end the transformation, click outside the selected object or objects. Indicates whether an instance of the Object class is in the prototype chain of the object specified as the parameter. Indicates whether the specified property exists and is enumerable. Sets the availability of a dynamic property for loop operations. Stops the play of a tweened animation at its current value.

Returns the string representation of this object, formatted according to locale-specific conventions. Checks whether an event listener is registered with this EventDispatcher object or any of its ancestors for the specified event type. Click for more information on events. Hide Inherited Events. Show Inherited Events. Property Detail. Implementation public function get duration : Number public function set duration value: Number : void. Example provided by ActionScriptExamples.

Implementation public function get position : Number public function set position value: Number : void. Implementation public function get time : Number public function set time value: Number : void. Parameters obj : Object — Object that the Tween targets. The function uses seconds if true or frames in relation to the value specified in the duration parameter if false.

Related API Elements fl. Related API Elements start. Event Object Type: fl. TweenEvent property TweenEvent. The properties of the event object have the following values: Property Value bubbles false cancelable false currentTarget The object that defines the event listener that handles the event.

For example, if you use myButton. Use the currentTarget property to always access the object listening for the event. Examples How to use this example.

This example animates a rectangle using the value provided by entering a number in a text field. The text field sets the width property of the tweened square to match the provided value.
