Need Help With Scene 2d and Buttons

PyNewb94

So in my code I have a script which shows a button on screen , when I press the button it’s suppose to make a sound but it doesn’t , eventually I want the button to control the character here’s the code

from scene import *
import ui
import sound 
import os 

x, y = get_screen_size()

button_font = ('Avenir Next' , 20)


class ButtonNode (SpriteNode):
	def __init__(self, title, *args, **kwargs):
		SpriteNode.__init__(self, 'pzl:Button1', *args, **kwargs)
		button_font = ('Avenir Next', 20)
		self.title_label = LabelNode(title, font=button_font, color='black', position=(0,1), parent=self)
		self.title = title
		


class Game(Scene):
	def setup(self):
		
		
		self.background_color = '#000000'
		self.btn = ButtonNode ('Rotate')
		self.btn.position =(100,80)
		self.add_child(self.btn)
		
		def touch_began(self, touch):
		 self.handle_touch(touch)
		 
		 
		def touch_moved(self, touch):
			pass
		
		def touch_ended(self, touch):
			pass 
		
		def handle_touch(self, touch):
		 if touch.location in self.btn.frame:
		 	sound.play_effect('8ve:8ve-beep-attention')
		
		self.player = SpriteNode('spc:PlayerShip2Red')
		self.player.anchor_point = (0.5, 0)
		self.player.position = (self.size.w/2, 120)
		self.player.size = (20,20)
		self.add_child(self.player)
		
		
		
if __name__=='__main__':
			run(Game(),LANDSCAPE, show_fps = True, multi_touch = True )

Can anyone point me in the right direction ?

@PyNewb94 you have a problem of indentation of your def's.

class Game(Scene):
  def setup(self):

    self.background_color = '#000000'
    self.btn = ButtonNode ('Rotate')
    self.btn.position =(100,80)
    self.add_child(self.btn)
    
  def touch_began(self, touch):
     self.handle_touch(touch)

cvp

Thus

from scene import *
import ui
import sound 
import os 

x, y = get_screen_size()

button_font = ('Avenir Next' , 20)


class ButtonNode (SpriteNode):
    def __init__(self, title, *args, **kwargs):
        SpriteNode.__init__(self, 'pzl:Button1', *args, **kwargs)
        button_font = ('Avenir Next', 20)
        self.title_label = LabelNode(title, font=button_font, color='black', position=(0,1), parent=self)
        self.title = title
        


class Game(Scene):
    def setup(self):
        
        
        self.background_color = '#000000'
        self.btn = ButtonNode ('Rotate')
        self.btn.position =(100,80)
        self.add_child(self.btn)
        
    def touch_began(self, touch):
        self.handle_touch(touch)
         
         
    def touch_moved(self, touch):
        pass
        
    def touch_ended(self, touch):
        pass 
        
     
    def handle_touch(self, touch):
        if touch.location in self.btn.frame:
            sound.play_effect('8ve:8ve-beep-attention')
        
        self.player = SpriteNode('spc:PlayerShip2Red')
        self.player.anchor_point = (0.5, 0)
        self.player.position = (self.size.w/2, 120)
        self.player.size = (20,20)
        self.add_child(self.player)
        
        
        
if __name__=='__main__':
            run(Game(),LANDSCAPE, show_fps = True, multi_touch = True )

@cvp how would I set the code up to make the player rotate when I press the button ?

mikael

@PyNewb94, check the Action class (and consider where you have the anchor point).

E.g.

self.player.run_action(Action.rotate_by(math.pi, 1))

Rotates the node by a relative 180 degrees in 1 second.

@cvp Okay got it to rotate left and to rotate right , how can I go about applying force now like a thrust , I tried action_by But spaceship jumps across the screen ,

cvp

@PyNewb94 I'm not a specialist of Scene, action.. and the guy who adviced "action rotate" is @mikael

enceladus

https://github.com/encela95dus/ios_pythonista_examples contains some scene examples (look at the scene section of the readme ).

mikael

@PyNewb94, you can

run_action(Action.forever(Action.move_by(*speed)), "thrust")

where speed is an (x,y) tuple or a Point, giving the relative change in ship’s position in 0.5 seconds. You change the speed by starting the action again with the same key, "thrust", or stop it with Node.remove_action.
