[SOLVED] Calling methods every n seconds in scene.update()

[Splefix]

Hi, I want to know if it is possible to call a method every n seconds (example: every 1 second) in scene.update.

If this is possible, can you please provide the right way of going about this?

Thank you, and God bless you all abundantly in Jesus Christ!!!

@Splefix see here

@cvp Yield causes the LabelNodes to disappear, and other code seems to stop working when using it in the scene.update function. Do you maybe know why?

[cvp]

@Splefix No, sorry, I'm not skilled in Scene..

Basically, I want to add a point every 1 second automatically if a statement is currently true. How can I do this?

[JonB]

you will need to post some code.

you have a few choices. either an Action.delay/Action.call Action.sequence.

or, in scene.update you would check if self.t, and take action as approppriate.

or depend on update being called every 1/60 second, and just count frames:
in update:
if condition_is_true:
someobject.points += 1/60/n

then you will have a fractional points, and you would just floor when displaying it.

update should always try to exit as fast as it can -- nothing in your scene can change until it does.

@JonB

Here is the code for the update subclass:

    def update(self):
        self.score_label.run_action(Action.remove())
        self.goal_label.run_action(Action.remove())
        self.score_label = LabelNode(str(f'Score: {self.score}'), ('Arial Rounded MT Bold', 33), position=(self.size.x/2, (self.size.y/1)-133))
        
        self.goal_label = LabelNode(f'Goal: {self.goal}', position=(self.size.x/2, ((self.size.y/1)-133)+50))
        
        self.add_child(self.score_label)
        self.add_child(self.goal_label)
        
        if self.auto_amount >= 1:
            spawn_bubble(self, False)
        
        if self.chest_visible == True:
            if self.score >= self.goal:
                buy_automate_chest = SpriteNode('plc:Chest_Open', position=(self.size.x/2, self.size.y/5), parent=self)
                
                self.chest_location = buy_automate_chest.frame
            else:
                buy_automate_chest.run_action(Action.remove())```

So @Splefix - I have done something similar previously, where I needed to run different tasks at different intervals. Specifically, it was to upload IoT data from a pressure/temp/humidity sensor I have here, to an online MQTT server - but that is by the by.

This script shows how to set up 3 separate timers for task1, task2 and task3 (obviously amend the number of variables for your specific requirements)

# you will need the time module, so...
import time

# Then simply set up timers for each task you wish to run
last_task1=time.time()
last_task2=time.time()
last_task3=time.time()

# Execute specific tasks within each variable you have set up above

# to execute task1 every 5 seconds
if time.time()-last_task1>=5: 
    # run whatever code you need to execute every 5 seconds here
    # put your code for task1 here
    
    # then reset the timer for this task1
    last_task1=time.time()
    

# to execute task2 every 300 seconds
if time.time()-last_task2>300: 
    # run whatever code you need to execute every 300 seconds here
    # put your code for task2 here

    # then reset the timer for this task2
    last_task2=time.time()
    

# to execute task3 every 3 seconds
if time.time()-last_task3>3: 
    # run whatever code you need to execute every 300 seconds here
    # put your code for task2 here

    # then reset the timer for this task3
    last_task3=time.time()

Hope this helps.

@Splefix - specifically for your example...

# you will need the time module, so...
import time

# set the variable for your single timer
last_task1=time.time()

# then execute task1 every 1 second if 'your_statement' is true
if your_statement == True:
    if time.time()-last_task1>=1:
        # run whatever code you need to execute every 1 second here
        # put your code for task1 here

        # then reset the timer for this task1
        last_task1=time.time()

dont use time module in scene. use the scene t parameter.

here is an example showing three methods i mentioned

[Splefix]

@musicman305 Haha brother, God just helped me figure that out myself! Thank you very much though for your answer! God bless you abundantly and may peace be with you!!!

Nice meeting you brother!

[JonB]

why are you deleting you goal/score label every frame! instead of just updating the text?

[Splefix]

@JonB Hey, can I ask you to show me an example of calling a method containing args using the example you gave me above?

[JonB]

use lambda, or functools.partial.

i.e Action.call(lambda arg1:self.some_method(arg1) )

You're very welcome matey...

[Splefix]

@JonB Concerning your question above: Can you show me how to update the text? This is my first time using the scene module.

Also, say I have two args, and the function is out of the MyScene class: How would I tackle this?

[JonB]

see my example, the .text attribute is used to update text.
note, you probably want to set the anchor_point=(0,0) for left justification, unless you want the text centered.

Lambdas accept multiple args
lambda arg1,arg2:some_function(arg1, arg2)

If you do a lot of these types of things, I (once again) promote the scripter, which works with views and scenes, for example like this:

from scene import *
from scripter import *

class MyScene (Scene):
    def setup(self):
        self.ship = SpriteNode('spc:PlayerShip1Orange')
        self.ship.position = self.size / 2
        self.add_child(self.ship)
        self.do_a_thing_every_second()
        
    @script
    def do_a_thing_every_second(self):
      while(True):
        print('do the thing')
        yield 1.0

run(MyScene())

@mikael Hi friend, I am having trouble with importing scripter? It says that this is invalid syntax:

from scripter import *

[mikael]

@Splefix, as an unfortunate barrier to entry, you need to download scripter.py from the link and place it in your site-packages.

[Splefix]

@mikael Hey sorry man, I am new to Pythonista, especially concerning the installation you are talking about. Can you please help me install scripter? If it isn’t too much trouble. I haven’t worked with github before either.
