The click variable is meant to go up by one everytime I click the button. What do I do?. :(

Thanks in advance!

Here's the code:

from scene import *
from PIL import Image
clicks = 0
class JitterClick(Scene):
    def setup(self):
        self.button = Button(Rect(self.size.w/2-100, self.size.h/2-140, 200, 200))
        self.button.background = Color(0,0,0)
        self.button.stroke = Color(0,0,0)
        self.button.image = 'Red_Circle'
        self.button.action = self.add_clicks
    def add_clicks(sender):
        global clicks
        clicks += 1
    def draw(self):
        self.button.draw()
        text('Clicks: %i' % clicks, x=self.size.w/2, y=self.size.h/4*3, font_size=64)
run(JitterClick())

Sorry

Lmao, I still need help

Here's a very simple scene that counts clicks/touches, hope that helps:

from scene import *
clicks = 0

class ClickScene(Scene):
    def touch_began(self, touch):
        # the "global" keyword is important here:
        global clicks
        clicks += 1

    def draw(self):
        background(0, 0, 0)
        text('Clicks: %i' % clicks, 'Helvetica', 30, self.size.w/2, self.size.h/2, 5)

run(ClickScene())

I NEED HELP AGAIN!!!

@omz what can I do about the global error

What "global error"? You need to be a little more specific.

When the code is run there is a global error on the text().

Why not in your setup method, just do self.clicks = 0. Then reference self.clicks thereafter. I had to do that before in your previous code to get it to run. No need for the global.

This should work

from scene import *
#clicks = 0

class ClickScene(Scene):
    def setup(self):
        self.clicks = 0

    def touch_began(self, touch):
        # the "global" keyword is important here:
        #global clicks
        #clicks += 1
        self.clicks += 1

    def draw(self):
        background(0, 0, 0)
        # clicks, changed to self.clicks below
        text('Clicks: %i' % self.clicks, 'Helvetica', 30, self.size.w/2, self.size.h/2, 5)

run(ClickScene())

Man, stop writing in caps and pretending answers like a little kid -.-

😑

So much for your help @filippocld

The global error in the original script is caused by the fact that the first click is singular (without an 's') and the second clicks is plural (with an 's') so they are not the same variable.

Changed the question.

Add the following line as the last line of setup():

        self.add_layer(self.button)

This will make the counter update but you will have a screen refresh problem to solve. See the draw() methods that @omz and @Phukett2 have provided above for a partial answer to your refresh problem.

THANK YOU!

I figured out how to fix the screen refresh error.
Thanks a lot everyone!
