help with game - hammza - Oct-30-2017 hi every one I'm trying to make a game , i need help to make the bullet start from the ship i don't know how to use coords this is the code from tkinter import * import random import time WIDTH=600 HEIGHT=400 tk=Tk() c=Canvas(tk,width=WIDTH,height=HEIGHT) c.pack() def ship(a): c.create_polygon(a,a/2,a-20,a/2+30,a+20,a/2+30,fill="blue") return a def bullet(i): c.create_oval(i,i,i+5,i+5,fill="blue") #=================== KEYS ===================================== def go_left(event): c.move(1,-5,0) c.update() def go_right(event): c.move(1,5,0) c.update() def go_up(event): c.move(1,0,-5) c.update() def go_down(event): c.move(1,0,5) c.update() def spaceKey(event=0): c.move(2,0,-100) c.update() ship=ship(300) bult=bullet(298) tk.bind("<Left>", go_left) tk.bind("<Right>", go_right) tk.bind("<Up>", go_up) tk.bind("<Down>", go_down) tk.bind('<space>',spaceKey) tk.mainloop() RE: help with game - heiner55 - Nov-11-2017 See https://python-forum.io/Forum-Game-Tutorials RE: help with game - hammza - Nov-11-2017 (Nov-11-2017, 03:24 PM)heiner55 Wrote: See https://python-forum.io/Forum-Game-Tutorials Thank you very much But Iam looking for a canvas solution without pygame RE: help with game - heiner55 - Nov-11-2017 >> make the bullet start from the ship def create_bullet(i): return c.create_oval(i,i/2,i+5,i/2+5,fill="blue") RE: help with game - hammza - Nov-12-2017 (Nov-11-2017, 05:25 PM)heiner55 Wrote: >> make the bullet start from the ship Thank you, I'll try this tomorrow RE: help with game - heiner55 - Nov-13-2017 I took the liberty of changing some names in your program from tkinter import * from time import time, sleep import random WIDTH =600 HEIGHT=400 tk=Tk() cs=Canvas(tk,width=WIDTH,height=HEIGHT) cs.pack() def create_ship(x,y): return cs.create_polygon(x,y, x-20,y+30, x+20,y+30, fill="blue") def create_bull(x,y): return cs.create_oval(x-3,y-3, x+3,y+3, fill="blue") def go_left(event): cs.move(ship,-5,0) cs.update() def go_right(event): cs.move(ship,5,0) cs.update() def go_up(event): cs.move(ship,0,-5) cs.update() def go_down(event): cs.move(ship,0,5) cs.update() def spaceKey(event=0): cs.move(bult,0,-50) cs.update() ship = create_ship(300,200) bult = create_bull(300,200) tk.bind("<Left>", go_left) tk.bind("<Right>", go_right) tk.bind("<Up>", go_up) tk.bind("<Down>", go_down) tk.bind('<space>', spaceKey) tk.mainloop() RE: help with game - hammza - Nov-13-2017 (Nov-13-2017, 06:13 AM)heiner55 Wrote: I took the liberty of changing some names in your program Thank you very much for your help Your idea is good But I'm looking for something else, What i want is how to make it shoot like (space invaders), I don't know how to use coords, and I didn't found any good tutorial or explanation. Thank you again RE: help with game - metulburr - Nov-13-2017 Quote:What i want is how to make it shoot like (space invaders), I don't know how to use coords, and I didn't found any good tutorial or explanation.Thats because no one uses tkinter to make games. There is a better library to handle that kind of software and it called pygame. In fact, we have a tutorial on how to make a ship shoot like space invaders on this forum. Tkinter is a GUI library mainly for building window form apps. RE: help with game - heiner55 - Nov-13-2017 This needs big changes. A class for the ship and a class for the bullet. Each class take care of the position x and y and has a draw/update function. Then you need a function which is called every 1/100s. This function calls all updates functions from your ship and from many bullets. You should google for ping pong. If you understand ping pong, you can also code your game. See https://gist.github.com/calebrob6/4022622 RE: help with game - Windspar - Nov-13-2017 here an example import tkinter as tk SCREEN = 600, 400 class Bullet: def __init__(self, canvas, x, y, tk_fill, movement): self.bullet = canvas.create_oval(x -3 , y - 3, x + 3, y + 3, fill=tk_fill) self.movement = movement def move(self, canvas): canvas.move(self.bullet, self.movement[0], self.movement[1]) class App(tk.Frame): def __init__(self, master): # put canvas in frame so you can have other goodies tk.Frame.__init__(self, master) self.pack() self.canvas = tk.Canvas(self, width=SCREEN[0], height=SCREEN[1]) self.canvas.pack() self.bullets = []# store bullets self.tick_loop() # start the tick loop self.ship = self.create_ship(300, 370, "blue") master.bind("<Left>", self.go_left) master.bind("<Right>", self.go_right) master.bind("<Up>", self.go_up) master.bind("<Down>", self.go_down) master.bind("<space>", self.space_key) def create_ship(self, x, y, tk_fill): return self.canvas.create_polygon(x, y, x - 20, y + 30, x + 20, y + 30, fill=tk_fill) def tick_loop(self): remove_list = for enum, bullet in enumerate(self.bullets): if self.canvas.coords(bullet.bullet)[1] < 0: remove_list.append(enum) self.canvas.delete(bullet.bullet) else: bullet.move(self.canvas) for index in remove_list: self.bullets.pop(index) # framerate per seconds 1000/30 = 30 frames roughly self.after(int(1000/30), self.tick_loop) def go_left(self, event): self.canvas.move(self.ship, -5, 0) self.canvas.update() def go_right(self, event): self.canvas.move(self.ship, 5, 0) self.canvas.update() def go_up(self, event): self.canvas.move(self.ship, 0, -5) self.canvas.update() def go_down(self, event): self.canvas.move(self.ship, 0, 5) self.canvas.update() def space_key(self, event=0): # only want the first two coords x, y = self.canvas.coords(self.ship)[:2] # just having shoot straight up self.bullets.append(Bullet(self.canvas, x, y, "blue", (0, -10))) def main(): root = tk.Tk() app = App(root) app.mainloop() if __name__ == '__main__': main()Don't like how keypress working but here it is.
