This factory creates an action rotating by a given angle amount.
The angle is measured in radians, counter-clockwise from the x-axis.
This class is actually a factory for creating movement actions. To create an action, call attach
with the appropriate SceneNode
. Note that this class contains no duration information. That is supplied when the action is added to ActionTimeline
.
|
inline |
Creates an uninitialized rotation animation.
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 animation, disposing all resources
|
inlinestatic |
Returns a newly allocated, degenerate rotation animation.
The rotation amount is set to 0.0, meaning no rotation takes place.
|
inlinestatic |
Returns a newly allocated rotation animation of the given angle.
When animated, this action will rotate its target by the given delta. The angle is measured in radians, counter-clockwise from the x-axis.
delta | The amount to rotate the target node |
ActionFunction cugl::scene2::RotateBy::attach | ( | const std::shared_ptr< scene2::SceneNode > & | node | ) |
Returns an action attaching this animation to the given scene node
This action will reference this object during the animation. Any changes to this object during that time may alter the animation.
Note that the action has no associated duration. That should be set when it is added to ActionTimeline
.
node | The node to attach |
|
inline |
Disposes all of the resources used by this animation.
A disposed animation can be safely reinitialized.
|
inline |
Returns the rotation delta for this action.
Changing this value for an actively animating action can have undefined side effects.
|
inline |
Initializes a degenerate rotation animation.
The rotation amount is set to 0.0, meaning no rotation takes place.
bool cugl::scene2::RotateBy::init | ( | float | delta | ) |
Initializes a rotation animation of the given angle.
When animated, this action will rotate its target by the given delta. The angle is measured in radians, counter-clockwise from the x-axis.
delta | The amount to rotate the target node |
|
inline |
Sets the rotation delta for this action.
Changing this value for an actively animating action can have undefined side effects.
delta | the rotation delta for this action. |
