ActionTween is an action that lets you update any property of an object. For example, if you want to modify the "width" property of a target from 200 to 300 in 2 seconds, then:
Another example: ScaleTo action could be rewritten using PropertyAction:
|
static |
Create and initializes the action with the property name (key), and the from and to parameters.
duration | The duration of the ActionTween. It's a value in seconds. |
key | The key of property which should be updated. |
from | The value of the specified property when the action begin. |
to | The value of the specified property when the action end. |
|
overridevirtual |
Called before the action start.
It will also set the target.
target | A certain target. |

time a value between 0 and 1.
For example:
time | A value between 0 and 1. |
