base_actions.Action --+ | base_actions.IntervalAction --+ | JumpBy --+ | JumpTo
Moves a CocosNode object to a position simulating a jump movement by modifying it's position attribute.
Example:
action = JumpTo(50,200, 5, 6) # Move the sprite 200 pixels to the right sprite.do( action ) # in 6 seconds, doing 5 jumps # of 50 pixels of height
start(self)
External code sets self.target and then calls this method.
|
|
__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)
|
|
__reversed__(self) (Inherited from cocos.actions.interval_actions.JumpBy) | |
done(self)
When in the worker role, this method is reliable.
(Inherited from cocos.actions.base_actions.IntervalAction)
|
|
init(self,
position=( 0, 0) ,
height=100,
jumps=1,
duration=5)
Init method
(Inherited from cocos.actions.interval_actions.JumpBy)
|
|
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)
|
|
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)
|
|
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,
(Inherited from cocos.actions.interval_actions.JumpBy)
t will be equal to 0
at 0 seconds. |
target
CocosNode object that is the target of the action
(Inherited from cocos.actions.base_actions.Action)
