Still in the early process of my game. However, I want it so the coin sound effect doesn't start playing (when it intersects) until the FIRST tap of the screen. Then the rest is the same.
Thanks in advance!
Here's the code:

import random, scene, sound
from scene import *
import sys

g_speed = 5
g_number_of_enemies = 10

def random_color():
    return scene.Color(random.random(), random.random(), random.random())

class Particle(object):
    def __init__(self, frame=None, velocity=None, color=None):
        self.frame = frame or scene.Rect(0, 0, 25, 25)
        self.velocity = velocity or scene.Point(0, 0)
        self.color = color or random_color()

    def update(self):
        self.frame.x += self.velocity.x
        self.frame.y += self.velocity.y

    def draw(self):
        self.update()
        scene.stroke(0, 0, 0)
        scene.fill(*self.color)
        scene.rect(*self.frame)

        if (self.frame.y <= bounds.y

        frame = scene.Rect(140, (self.bounds.h - player_size) / 2, player_size, player_size)
        color = scene.Color(1, 1, 1)
        return Particle(frame=frame, color=color)

    def draw(self):

[SOLVED!] Help needed with touch (game)
