base_actions.Action --+ | Driver
Drive a CocosNode object around like a car in x, y according to a direction and speed.
Example:
# control the movement of the given sprite sprite.do(Driver()) ... sprite.rotation = 45 sprite.speed = 100 ...
The sprite MAY have these parameters (beyond the standard position and rotation):
speed
: float- Speed to move at in pixels per second in the direction of the target's rotation.
acceleration
: float- If specified will automatically be added to speed. Specified in pixels per second per second.
max_forward_speed
: float (default None)- Limits to apply to speed when updating with acceleration.
max_reverse_speed
: float (default None)- Limits to apply to speed when updating with acceleration.
step(self,
dt)
Gets called every frame.

__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.Action)
|
|
__or__(self,
action)
spawn operator - runs two actions in parallel
action1 | action2 -> action_result
(Inherited from cocos.actions.base_actions.Action)
|
|
__reversed__(self) (Inherited from cocos.actions.base_actions.Action) | |
done(self)
False while the step method must be called.
(Inherited from cocos.actions.base_actions.Action)
|
|
init(*args,
**kwargs)
Gets called by __init__ with all the parameteres received,
At this time the target for the action is unknown.
(Inherited from cocos.actions.base_actions.Action)
|
|
start(self)
External code sets self.target and then calls this method.
(Inherited from cocos.actions.base_actions.Action)
|
|
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.
(Inherited from cocos.actions.base_actions.Action)
|
target
CocosNode object that is the target of the action
(Inherited from cocos.actions.base_actions.Action)
|
dt
is the number of seconds that elapsed
since the last call.
