Modifying Instance Properties Flash

Every instance of a symbol has specific properties that can be modified. These properties only apply to the specific instance not to the original symbol. Properties such as the brightness, tint, alpha (transparency), and behavior can all be modified. An instance can also be scaled, rotated, and skewed. As previously discussed, any changes made to the original symbol will be reflected in each instance this still holds true even if the instance’s properties are modified.

Modifying color effects with symbols
Each instance of a symbol can have a variety of color effects applied to it. The basic effects are changes of brightness, tint, and alpha (transparency). Tint and alpha changes can also be combined for special effects. To apply color effects to a symbol instance:

  1. Select the instance that you want to modify.
  2. Open the Effect Panel with Window➪Panels➪Effect.
  3. Select one of the options from the drop-down menu. The Effect Panel drop-down with the Tint option selected shows below.
  4. The Effects Panel has several options to choose from. Shown here is the Effect drop-down with the Tint option selected.

    Effects Panel has several options

    The options available from the Effect drop-down are as follows:

    • None: No effect is applied.
    • Brightness: Adjusts the relative brightness or darkness of the instance. It ranges from 100 percent (black) to 100 percent (white). Use the slider to change the value or just type a numeric value into the entry field.
    • Tint: Enables you to change the color of an instance. Either select a hue with the color picker, or enter the RGB values directly. Then, select the percentage of saturation (Tint Amount) by using the slider or by entering the percentage in the entry field. This number ranges from 0 percent (no saturation) to 100 percent (completely saturated).
    • Alpha: Enables you to modify the transparency of an instance. Select a percentage by using the slider or by entering a number directly. The Alpha percentage ranges from 0 percent (completely transparent) to 100 percent (no transparency).
    • Advanced: Enables you to adjust the tint and alpha settings of an instance. The controls on the left reduce the tint and alpha values by a specified percentage, while the controls on the right either reduce or increase the tint and alpha values by a constant value. The current values are multiplied by the numbers on the left, and then added to the values on the right.

Changing the behavior of an instance
You don’t need to limit yourself to the native behavior of a symbol. There may be times when you want an animated Graphic symbol to have the behavior of a Movie Clip. You don’t have to go through the extra effort of creating a new symbol just change the behavior of the instance as needed:

  1. Select the instance that you want to modify.
  2. Open the Instance Panel with Window➪Panels➪Instance, or click the Instance Button on the Launcher.
  3. From the Behavior drop-down, select the desired behavior. As shown below you can select Graphic, Button, or Movie Clip, which is the default behavior.
  4. As this composite screen shot indicates, you can change the Behavior of an instance from the Instance Panel.

Switching symbols
There may be times when you need to replace an instance of one symbol with another symbol. You don’t have to go through and recreate your entire animation to do this just use the Switch Symbol feature. This feature only switches the instance of the symbol for an instance of another symbol all other modifications previously applied to the instance will remain the same. Here’s how to switch symbols:

  1. Select the instance that you want to switch.
  2. Open the Instance Panel with Window➪Panels➪Instance (or use the Instance Button on the Launcher).
  3. Click the Swap Symbol button and, from the ensuing Swap Symbol dialog , select the symbol that you want to switch to.
