Today in class, I finished my spacewar game. I added a background image, and explosions.

This is the code for the background image.

turtle.bgpic("starfield.gif")

This is the code that makes the player smaller.

self.shapesize(stretch_wid=0.6, stretch_len=1.1, outline=None)

This is the code for the explosion particles.

class Particle(Sprite):
	def __init__(self, spriteshape, color, startx, starty):
		Sprite.__init__(self, spriteshape, color, startx, starty)
		self.shapesize(stretch_wid=0.1, stretch_len=0.1, outline=None)
		self.goto(-1000,-1000)
		self.frame = 0			
		
	def	explode(self, startx, starty):
		self.goto(startx,starty)
		self.setheading(random.randint(0,360))
		self.frame = 1

	def move(self):
		if self.frame > 0:
			self.fd(10)	
			self.frame += 1

		if self.frame > 15:
			self.frame = 0
			self.goto(-1000, -1000)	

This is the code for the particles.

particles = []	
for i in range(20):
	particles.append(Particle("circle", "orange", 0, 0))

This is the code that does the explosion.

for particle in particles:
    particle.explode(missile.xcor(), missile.ycor())
