I'm making a dumbed down version of agar.io.
Currently, the cell is placed upon a grid background like in the game. The cell eats food, but only a smaller square section inside the circle actually eats the food (in my program), which is noticeable when you are big enough. Also, when you press the spacebar, it would split the cell into 2 smaller parts, which after a few seconds would merge back. This would require a KEY_UP and K_SPACE event, but I am not sure how to implement that. Also, once you are around a mass of 34, you can press w to shoot a tiny bit of yourself, a smaller cell at around 14 set mass.
I attempted to slow down the cell once it reaches a certain mass with a bunch of if statements. In the game, it slows down naturally. Here and Here are sources depicting the math used in the game.
Here is the code I have:
import pygame, sys, random from pygame.locals import * # set up pygame pygame.init() mainClock = pygame.time.Clock() # set up the window width = 800 height = 600 thesurface = pygame.display.set_mode((width, height), 0, 32) pygame.display.set_caption('') bg = pygame.image.load("bg.png") basicFont = pygame.font.SysFont('calibri', 36) # set up the colors BLACK = (0, 0, 0) GREEN = (0, 255, 0) WHITE = (255, 255, 255) BLUE = (0, 0, 255) size = 10 playercolor = BLUE # set up the player and food data structure foodCounter = 0 NEWFOOD = 35 FOODSIZE = 10 player = pygame.draw.circle(thesurface, playercolor, (60, 250), 40) foods = [] for i in range(20): foods.append(pygame.Rect(random.randint(0, width - FOODSIZE), random.randint(0, height - FOODSIZE), FOODSIZE, FOODSIZE)) # set up movement variables moveLeft = False moveRight = False moveUp = False moveDown = False MOVESPEED = 10 score = 0 # run the game loop while True: # check for events for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() if event.type == KEYDOWN: # change the keyboard variables if event.key == K_LEFT or event.key == ord('a'): moveRight = False moveLeft = True if event.key == K_RIGHT or event.key == ord('d'): moveLeft = False moveRight = True if event.key == K_UP or event.key == ord('w'): moveDown = False moveUp = True if event.key == K_DOWN or event.key == ord('s'): moveUp = False moveDown = True if event.type == KEYUP: if event.key == K_ESCAPE: pygame.quit() sys.exit() if event.key == K_LEFT or event.key == ord('a'): moveLeft = False if event.key == K_RIGHT or event.key == ord('d'): moveRight = False if event.key == K_UP or event.key == ord('w'): moveUp = False if event.key == K_DOWN or event.key == ord('s'): moveDown = False if event.key == ord('x'): player.top = random.randint(0, height - player.height) player.left = random.randint(0, width - player.width) if event.type == MOUSEBUTTONUP: foods.append(pygame.Rect(event.pos[0], event.pos[1], FOODSIZE, FOODSIZE)) foodCounter += 1 if foodCounter >= NEWFOOD: # add new food foodCounter = 0 foods.append(pygame.Rect(random.randint(0, width - FOODSIZE), random.randint(0, height - FOODSIZE), FOODSIZE, FOODSIZE)) if 100>score>50: MOVESPEED = 9 elif 150>score>100: MOVESPEED = 8 elif 250>score>150: MOVESPEED = 6 elif 400>score>250: MOVESPEED = 5 elif 600>score>400: MOVESPEED = 3 elif 800>score>600: MOVESPEED = 2 elif score>800: MOVESPEED = 1 # move the player if moveDown and player.bottom < height: player.top += MOVESPEED if moveUp and player.top > 0: player.top -= MOVESPEED if moveLeft and player.left > 0: player.left -= MOVESPEED if moveRight and player.right < width: player.right += MOVESPEED thesurface.blit(bg, (0, 0)) # draw the player onto the surface pygame.draw.circle(thesurface, playercolor, player.center, size) # check if the player has intersected with any food squares. for food in foods[:]: if player.colliderect(food): foods.remove(food) size+=1 score+=1 # draw the food for i in range(len(foods)): pygame.draw.rect(thesurface, GREEN, foods[i]) printscore = basicFont.render("Score: %d" % score, True, (0,0,0)) thesurface.blit(printscore, (495, 10)) pygame.display.update() # draw the window onto the thesurface pygame.display.update() mainClock.tick(80) Once again, here are the issues I want to solve.
- I want the cell to split into 2 parts when the spacebar is pressed. This can happen only if the cell is above 30 size.
- I want the cell to spit out a fraction of itself when you press W. The part that is spit out will be a set 15 mass. The original cell will be 15 smaller. Hitting W multiple times will allow multiple small balls to be spit out, until the original cell's mass is 20, in which case it isn't viable to spit out any more.
Edit: I have tried doing the splitting thing:
if event.key == K_SPACE: pygame.draw.circle(thesurface, playercolor,(player.centerx,player.centery),int(size/2)) pygame.draw.circle(thesurface, playercolor,(player.centerx+size,player.centery+size),int(size/2)) After putting the above code in, and running the program and pressing the spacebar, nothing happens. The program acts like I never pressed it.
