Я создаю игру с использованием Python и Pygame.
Я использовал эту функцию перед использованием JS с p5.js и Java с libwjgl, но по какой-то причине она не работает с Pygame.
Я пытаюсь нанести статический удар по цели из движущегося объекта.Теперь мне не хватает цели.Вы можете увидеть это в GIF.Каждый снаряд должен поразить цель (теперь все пропускает, но выстрелы в правильном направлении)
Пуля стреляет, когда игрок нажимает кнопку мыши.
Вот как я это делаю:
def shoot(self):
posX, posY = 100, 100 # Static target coordinates
diffX = self.player.x - posX
diffY = self.player.y - posY
distance = math.sqrt((diffX * diffX) + (diffY * diffY)) # Calculate the distance
velX = float((-1 / distance * diffX * 6)) # Calculate volocity required to hit the target
velY = float((-1 / distance * diffY * 6)) # Calculate volocity required to hit the target
# Bullet(x, y, width, height, velocityX, velocityY)
# Will be rendered on the screen
self.bullets.append(Bullet(self.player.x, self.player.y, 10, 10, velX, velY)) # The bullet is added to array, which later gets rendered on the screen
Класс маркера:
import pygame
class Bullet(object):
def __init__(self, x, y, width, height, velY, velX):
self.width = width
self.height = height
self.x = x
self.y = y
self.velX = velX
self.velY = velY
self.bullet = pygame.Rect(self.x, self.y, self.width, self.height)
def render(self, screen):
pygame.draw.rect(screen, (255, 255, 255), self.bullet)
def update(self):
self.bullet.x += self.velX
self.bullet.y += self.velY
Это прекрасно работает с другими языками, которые я упомянул, но в Python запущенный снаряд выключен ...
Вот как этовыглядит.Красный квадрат - цель:
СПАСИБО, ВСЕМ, ЗА ПОМОЩЬ.Я действительно ценю это:)
