                    _ReverseTime

Executes an action in reverse order, from time=duration to time=0

WARNING: Use this action carefully. This action is not sequenceable. Use it as the default `__reversed__` method of your own actions, but using it outside the `__reversed` scope is not recommended.

The default `__reversed__` method for all the Grid3DAction actions and Camera3DAction actions is `_ReverseTime()`.

## Methods

| init(self, other, *args, **kwargs) Gets called by __init__ with all the parameteres received, At this time the target for the action is unknown.
| start(self) External code sets self.target and then calls this method.
| stop(self) When the action must cease to perform this function is called by external code; after this call no other method should be called.
| update(self, t) Gets called on every frame 't' is the time elapsed normalized to [0, 1] If this action takes 5 seconds to execute, `t` will be equal to 0 at 0 seconds.
| __reversed__(self)
| __add__(self, action) sequence operator - concatenates actions action1 + action2 -> action_result where action_result performs as: first do all that action1 would do; then perform all that action2 would do (Inherited from cocos.actions.base_actions.Action)
| __init__(self, *args, **kwargs) dont override - use init (Inherited from cocos.actions.base_actions.Action)
| __mul__(self, other) repeats ntimes the action action * n -> action_result where action result performs as: repeat n times the changes that action would do (Inherited from cocos.actions.base_actions.IntervalAction)
| __or__(self, action) spawn operator - runs two actions in parallel action1 | action2 -> action_result (Inherited from cocos.actions.base_actions.Action)
| done(self) When in the worker role, this method is reliable. (Inherited from cocos.actions.base_actions.IntervalAction)
| step(self, dt) Dont customize this method: it will not be called when in the component role for certain composite actions (like Sequence_IntervalAction). (Inherited from cocos.actions.base_actions.IntervalAction)

## Instance Variables

| target CocosNode object that is the target of the action (Inherited from cocos.actions.base_actions.Action)

## Method Details

### init

init(self, other, *args, **kwargs)
Gets called by __init__ with all the parameteres received, At this time the target for the action is unknown. Typical use is store parameters needed by the action.

Overrides:
  Action.init

### start

start(self)
External code sets self.target and then calls this method. Perform here any extra initialization needed.

Overrides:
  Action.start

### stop

stop(self)
When the action must cease to perform this function is called by external code; after this call no other method should be called.

Overrides:
  Action.stop

### update

update(self, t)
Gets called on every frame 't' is the time elapsed normalized to [0, 1] If this action takes 5 seconds to execute, `t` will be equal to 0 at 0 seconds. `t` will be 0.5 at 2.5 seconds and `t` will be 1 at 5sec. This method must not use self._elapsed, which is not guaranted to be updated.

Overrides:
  IntervalAction.update

### __reversed__

__reversed__(self)

Overrides:
  Action.__reversed__
