So, I've been working on this animation player kinda thing lately to make it reusable in future projects. After i attempted to implement the reverse feature, it just didn't work properly, i start from the last frame of the spritesheet, keeps going, reaches the first frame and boom suddenly it works for the rest of the time the project is run. Here is my code (if you have any questions about how it functions feel free to ask): class Spritesheet: def __init__(self, filename, pos, scale, frame_h, frame_v, current_frame: Vector2): self.filename = filename self.pos = pos self.scale = scale self.frame = current_frame self.frame_h = frame_h self.frame_v = frame_v self.image = load_image(self.filename) self.texture = load_texture_from_image(self.image) self.rect = Rectangle(self.frame.x * self.image.width / self.frame_h, self.frame.y * self.image.height / self.frame_v, self.texture.width / self.frame_h, self.texture.height / self.frame_v) def draw(self): draw_texture_pro( self.texture, self.rect, Rectangle(self.pos.x, self.pos.y, self.rect.width * self.scale, self.rect.height * self.scale), Vector2(0, 0), 0, WHITE ) class Animation: def __init__(self, spritesheet, start_frame, end_frame, loop, vertical_anim: bool=False, speed: float = 10, reverse: bool = False): # Variables self.spritesheet = spritesheet self.start_frame = start_frame self.end_frame = end_frame self.loop = loop self.speed = speed self.reverse = reverse self.vertical_anim = vertical_anim self.frame_attr = 'y' if self.vertical_anim else 'x' self.initial_frame = self.end_frame if self.reverse else self.start_frame setattr(self.spritesheet.frame, self.frame_attr, self.initial_frame) self.current_frame = getattr(self.spritesheet.frame, self.frame_attr) self.frame_counter = 0 def update(self): self.animate() self.current_frame = getattr(self.spritesheet.frame, self.frame_attr) print(self.initial_frame) self.spritesheet.rect.x = self.spritesheet.frame.x * (self.spritesheet.image.width / self.spritesheet.frame_h) self.spritesheet.rect.y = self.spritesheet.frame.y * (self.spritesheet.image.height / self.spritesheet.frame_v) def animate(self): if self.frame_counter >= (framerate / self.speed): step = -1 if self.reverse else 1 new_frame = self.current_frame + step setattr(self.spritesheet.frame, self.frame_attr, new_frame) if self.is_finished(): if self.loop: # Reset to the correct loop start new_frame = self.end_frame if self.reverse else self.start_frame setattr(self.spritesheet.frame, self.frame_attr, new_frame) else: # Ensure it stops at the correct frame new_frame = self.start_frame if self.reverse else self.end_frame setattr(self.spritesheet.frame, self.frame_attr, new_frame) self.current_frame = new_frame self.frame_counter = 0 # Reset counter self.frame_counter += 1 def set_speed(self, new_speed): self.speed = new_speed def reset(self): setattr(self.spritesheet.frame, self.frame_attr, self.start_frame) self.frame_counter = 0 def is_finished(self): if self.reverse: return self.current_frame <= self.start_frame # Stop at start when reversing return self.current_frame >= self.end_frame def draw(self): self.spritesheet.draw() def run(self): self.update() self.draw() class AnimationPlayer: def __init__(self, animation_dict, default_animation): self.animation_dict = animation_dict self.current_animation = self.animation_dict[default_animation] def play(self, animation_name): if animation_name in self.animation_dict: self.current_animation = self.animation_dict[animation_name] self.current_animation.reset() # Reset animation when switching def run(self): self.current_animation.update() # Update animation frames self.current_animation.draw() # Draw the updated frame Here is the settings.py: from pyray import * from raylib import * import math, os, sys, json screen_width = 1280 screen_height = 720 framerate = 60 # Useful methods def clamp(value, min_value, max_value): return max(min_value, min(value, max_value)) def lerp(start, end, t): return start + (end - start) * clamp(t, 0, 1) def is_empty(obj): return isinstance(obj, (list, tuple, dict, set)) and len(obj) == 0 # Timer class Timer: def __init__(self, duration: int, repeat = False, autostart = False, func = None): self.duration = duration self.start_time = 0 self.active = False self.repeat = repeat self.func = func if autostart: self.activate() def activate(self): self.active = True self.start_time = get_time() def deactivate(self): self.active = False self.start_time = 0 if self.repeat: self.activate() def update(self): if self.active: if get_time() - self.start_time >= self.duration: if self.func and self.start_time: self.func() self.deactivate() I've tried to set the start_frame to the end_frame and vice versa with this piece of code: self.start_frame, self.end_frame = self.end_frame, self.start_frame But it just didn't work Continue reading...
