I'm making RPG game on pygame and one of the skills animation requires rotation on its center, the thing is when it collide with other sprites the collision area changes because of the rotation.
Here is my rotation function:
def rotate(self):
self.image = pygame.transform.rotozoom(self.image, self.angle, 1)
self.rect = self.image.get_rect(center=self.rect.center)
self.angle += 1
And this is the projectile class, which has the rotation function inside it basically if the projectile attribute equals to "big_star" it rotates it.
class Projectile(pygame.sprite.Sprite):
def __init__(self, x, y, direction, range, isRotate, projectile, damage):
pygame.sprite.Sprite.__init__(self)
self.range = range
self.projectile = projectile
self.speed = 12
self.hit_count = 0
self.damage = damage
self.isRotate = isRotate
if direction == 1:
self.flip = True
else:
self.flip = False
self.image = pygame.image.load(f'sprites/projectiles/{projectile}/0.png').convert_alpha()
self.image = pygame.transform.flip(self.image, self.flip, False)
self.rect = self.image.get_rect()
self.rect.center = (x, y)
self.direction = direction
self.angle = 0
def update(self, mobs, player):
#move projectile
self.rect.x += (self.direction * self.speed)
if self.isRotate:
self.rotate()
for mob in mobs:
if pygame.sprite.spritecollide(mob, player.projectiles_group, False):
if mob.alive and self.hit_count != 1:
mob.play_sound("mob","hit")
mob.health -= 25
mob.update_action(3)
if self.projectile != 'big_star':
self.kill()
self.hit_count += 1
#check if projectile has gone off range
if self.rect.x > (player.rect.x + self.range) or self.rect.x < (player.rect.x - self.range):
self.kill()
def rotate(self):
self.image = pygame.transform.rotozoom(self.image, self.angle, 1)
self.rect = self.image.get_rect(center=self.rect.center)
self.angle += 1
I think the reason for that is this line:
self.rect = self.image.get_rect(center=self.rect.center)
But I don't know how to fix it with out changing the rect, any ideas?
