Enemy Projectiles Attack Way To Fast Problem

2024/10/8 20:35:11

I am trying to make my enemy bullets attack the player but its attacking way to fast I dont know why VIDEO my enemy bullets class

    # enemys bulletsksud = pygame.image.load("heart.png")class Boolss(object):def __init__(self, x, y,color, xspeed, yspeed):self.x = xself.y = yself.xspeed = xspeedself.yspeed = yspeedself.ksud = pygame.image.load("heart.png")self.hitbox  = self.ksud.get_rect()self.rect  = self.ksud.get_rect()self.rect.topleft = (self.x,self.y)self.color = colorself.hitbox = (self.x + 57, self.y + 33, 29, 52) # NEWdef draw(self, window):self.rect.topleft = (self.x,self.y)player_rect = self.ksud.get_rect(center = self.rect.center) player_rect.centerx += 0 # 10 is just an exampleplayer_rect.centery += 0 # 15 is just an examplewindow.blit(self.ksud, player_rect)self.hitbox = (self.x + 97, self.y + 33, 10, 10) # NEWwindow.blit(self.ksud,self.rect)

this is where it appends bullet like attack the player

          for shootss in shootsright:shootss.x += shootss.xspeedshootss.y += shootss.yspeedif shootss.x > 500 or shootss.x < 0 or shootss.y > 500 or shootss.y < 0:shootsright.pop(shootsright.index(shootss))if len(shootsright) < 1:start_x = round(enemyshoots1.x+enemyshoots1.width-107)start_y = round(enemyshoots1.y + enemyshoots1.height-50)target_x = playerman.x+playerman.width//2target_y = playerman.y+playerman.width//2dir_x, dir_y = target_x - start_x, target_y - start_ydistance = math.sqrt(dir_x**2 + dir_y**2)if distance > 0:shootsright.append(Boolss(start_x,start_y,(0,0,0),dir_x, dir_y))#------------------------------------------------------------------------------
Answer

The problem is here:

start_x = round(enemyshoots1.x+enemyshoots1.width-107)
start_y = round(enemyshoots1.y + enemyshoots1.height-50)
target_x = playerman.x+playerman.width//2
target_y = playerman.y+playerman.width//2
dir_x, dir_y = target_x - start_x, target_y - start_y

If you print the dir_x and dir_y you'll see that the values are very high. You probably add this values each frame to the position of the bullet. That's why they leave the screen before you can really see them.

You could try this:

BULLET_SPEED = 5delta_x, delta_y = target_x - start_x, target_y - start_y
distance = math.sqrt(delta_x ** 2 + delta_y ** 2)
dir_x = BULLET_SPEED * delta_x / distance
dir_y = BULLET_SPEED * delta_y / distance

Consider that this solution doesn't rounds the values and pygame might throw an exception because of coordinates with float values. You should round the coordinates before using them for drawing.
