How to Use Tweening in Fireworks CS5
Tweening is provided as a tool for fine tuning animations in Adobe Fireworks Creative Suite 5. Tweening is the process of creating a state between two others, usually as a start or stop point for the animation. Use tweening to simulate an object moving, like a ball bouncing, or fading an image in or out of an animation.
Create a symbol
To use the tweening feature in Fireworks, you must have a symbol — for this example, an arrow. To create this symbol, follow these steps:
Choose File→New and create a new document large enough to contain your animation.
For this example, create a document that measures 500 pixels by 500 pixels.
Click and hold the Rectangle tool and select the Arrow tool from the Vector section of the Tools panel.
In the upper left corner of the canvas, click and drag to create a small arrow.
Choose Modify→Symbol→Convert to Symbol.
The Convert to Symbol dialog box appears.
Type an appropriate name (such as Arrow) for the symbol in the Name text box, select the Graphic radio button, and click OK.
Fireworks converts your arrow graphic to a symbol.
Clone the symbol
After you create a symbol, you need to clone the symbol to create start and end points for the animation. Follow these steps:
Select the arrow symbol on the canvas.
Holding down the Alt (Windows) or Option (Mac) key, drag the arrow to the lower right corner of the canvas.
By holding down the Alt or Option key while you drag, you’re cloning the arrow.
Choose the Scale tool in the Select section of the Tools panel and make the cloned arrow (in the lower right corner) larger than the original.
Using the Pointer tool, position both arrow symbols on the canvas the way you want them.
These symbols are the start and end points for your animation, so place them where you want the animation to begin and end.
Tweening the symbols
When you have two instances of the symbol on the artboard, you’re ready to tween the symbols to create an animation. Follow these steps:
Use the Pointer tool to select one of the arrow symbols and then Shift-click the other to select both at the same time.
Choose Modify→Symbol→Tween Instances.
The Tween Instances dialog box appears.
Enter a value in the Steps text box.
For this example, enter 5 to create five new states (or frames) for transforming the small arrow into the large arrow.
If you want the symbols to appear one at a time, you want those states to be distributed to separate states in the States panel, so select the Distribute to States check box.
Test your animation by clicking the Play button in the lower right section of the Fireworks workspace and then save the file.
