#!/usr/bin/env python3
# example.py

import pygame
import particlepy

import time
import random

pygame.init()

# pygame config
SIZE = 800, 800

pygame.mouse.set_visible(False)

# timing
clock = pygame.time.Clock()
FPS = 60

# delta time
old_time = time.time()
delta_time = 0

# particle system to manage particles
particle_system = particlepy.particle.ParticleSystem()

# main loop

# delta time

# update particle properties
particle_system.update(delta_time=delta_time)

# get mouse position

velocity=(random.uniform(-150, 150), random.uniform(-150, 150)),

# color manipulation
for particle in particle_system.particles:
particle.shape.color = particlepy.math.fade_color(particle=particle,
color=(83, 150, 181),
progress=particle.inverted_progress)

# render shapes
particle_system.make_shape()

# post shape creation manipulation
for particle in particle_system.particles:
particle.shape.angle += 5

# render particles
particle_system.render(surface=screen)

# update display
pygame.display.update()
screen.fill((13, 17, 23))
clock.tick(FPS)
