- allows you to skew an object horizontally and vertically.
There are three Skew animation actions available:
|
| - allows you to skew an object horizontally and vertically. |
|
| - allows you to skew an object horizontally. |
|
| - allows you skew an object vertically. |
Add the Skew Horizontal / Vertical, Skew Horizontal or Skew Vertical action to your trigger, as described in adding actions. The appropriate tab will automatically appear when you add the action.
At the top of the tab is the Object List. Click the name of the object in the list that you want to skew. By default, This Object is selected (see Note).
Note:
Only one object can be selected from the Object list. The default option This Object refers to the object in which this action has been placed – this option is useful if you want to copy this action to other objects that will follow the same animation because you do not have to re-select the new object name from the list.
Use the Amount panel to set the percentage the object should be skewed by. Enter the percentage in the Across or Down box (or both if you are using the Skew Horizontal / Vertical action).
The Across box sets the horizontal position of the object and therefore does not appear in the Amount panel for the Skew Vertical action. Equally, the Down box sets the vertical position of the object and does not appear in the Amount panel for the Skew Horizontal action.
You can enter positive or negative numbers in the Across and Down boxes. In the Across box a positive number will move the top of the object right, while a negative number will move the top of the object left. In the Down box a positive number will move the right-side of the object up, while a negative number will move the right-side of the object down. In the Skew Horizontal / Vertical action you can use positive and negative numbers to skew an object in a variety of ways. (see Skew examples).
Use the Duration option to set the time over which the animation will happen. Use the spin buttons to increase or decrease the time.
Note:
If the duration is set to 0 seconds, the animation will happen immediately. In other words, you won’t see the animation, just the end result.
Use the Type panel to set the type of movement the object will make. There are two options: Skew By and Skew To (see Note). By default the Skew By option is selected.
The Skew By option will skew the object from its current skew position by the number of pixels entered in the Amount panel i.e. if the object is currently skewed by 20% and you enter 80 in the Down box of the Amount panel, the object will have a final skew value of 100%.
The Skew To option will skew the object to the percentage of skew entered in the Amount panel regardless of the objects current skew position i.e. if the object is currently skewed by 20% and you enter 80 in the Down box of the Amount panel, the object will have a final skew value of 80%.
Note:
You can enter any number in the Amount panel – this means you can have objects skewed off the page. It is also useful to note that Opus will remember an objects current skew position, so you can reset objects you have skewed off the screen.
Click on the …once option if you want the object to animate just once.
Click on the times box if you want to set a specific number of times the object should animate. Use the spin buttons to set a specific number of times.
Click on the …continuously option if you want the object to animate continuously.
Note:
Use the Stop Animation action if you want to stop an object animating continuously.
Click on the down arrow to the right of the Speed Control option to select how the object will animate over a length of time, e.g. at a regular pace or faster at the beginning or end of the animation, and so on. By default, the Constant is selected.
Use the At End options to set the position of the object when it completes its animation. There are three options: Stop, Return and Reset. By default, the Stop option is selected.
Use the Send "Synchronise to End" trigger if you want to start a Synchronise to Animation End trigger when the object reaches the end of the animation.
Click on the Apply button to save your changes.
Note:
When using the Skew actions – it is the centre of the object that is skewed.
You can also skew an object at the same time that you create it using the Skew panel in the General tab of the object’s Properties dialog. This will set the skew of the object as it appears on the screen initially. Please note, this method does not animate the skew, it simply sets the amount of skew for the object.
