This action represents a fade-in towards total opacity.
When applied to a node, this action will adjust the alpha value of the node color until it is eventually 1. Unless the node is set for its children to inherit is color, this will have no affect on the children of the node.
An action contains only the definition of the animation. This can include information about the transform to use or the duration of the animation. However, it does not contain any attribute of the target. Hence, an action can be reapplied to different targets.
By itself, an action does nothing. It only specifies an action that may take place. To use an action, it must be passed to the ActionManager. The manager will create an action instance and animate that instance. While an action may be reused many times, an action instance corresponds to a single animation.
|
inline |
Creates an uninitialized fade-in action.
NEVER USE A CONSTRUCTOR WITH NEW. If you want to allocate an object on the heap, use one of the static constructors instead.
|
inline |
Deletes this action instance, disposing all resources
|
inlinestatic |
Returns a newly allocated, instantaneous fade-in towards opacity
When applied to a node, this action will adjust the alpha value of the node color until it is eventually 1. Unless the node is set for its children to inherit is color, this will have no affect on the children of the node.

inlinestatic |
Returns a newly allocated fade-in towards opacity
When applied to a node, this action will adjust the alpha value of the node color until it is eventually 1. Unless the node is set for its children to inherit is color, this will have no affect on the children of the node. The animation will take place over the given number of seconds.
time | The animation duration |
|
overridevirtual |
Returns a newly allocated copy of this Action.
Reimplemented from cugl::scene2::Action.
|
inline |
Disposes all of the resources used by this action.
A disposed action can be safely reinitialized.

overridevirtual |
Prepares a target for action
The important state of the target is stored in the given state parameter. The semantics of this state is action-dependent.
target | The node to act on |
state | The relevant node state |
Reimplemented from cugl::scene2::Action.
|
overridevirtual |
Returns a string representation of the action for debugging purposes.
If verbose is true, the string will include class information. This allows us to unambiguously identify the class.
verbose | Whether to include class information |
Reimplemented from cugl::scene2::Action.

overridevirtual |
Executes an action on the given target node.
The important state of the target is stored in the given state parameter. The semantics of this state is action-dependent.
target | The node to act on |
state | The relevant node state |
dt | The elapsed time to animate. |
