I've been trying to get a Sonic The Hedgehog game working in Pygame and it works for the most part. Sonic can run fast, jump across platforms like a normal platformer, gets affected by gravity, collects rings, etc. (check attached video) https://imgur.com/a/q1YrAXO However, I cannot for the life of me get Sonic to run at different angles and go up slopes and loops like in the real games. I am aware such a project doesn't exist in Pygame (for the public to access anyway) and making the precise, mathematically accurate scripts can be hard to do. Problematic code: (from levels.py) def update(self): self.sonic.update() self.camera.update(self.sonic) # Follow Sonic # Keep Sonic grounded self.sonic.grounded = False for tile in self.tile_group: if self.sonic.mask.overlap(tile.mask, (tile.rect.x - self.sonic.hitbox.x, tile.rect.y - self.sonic.hitbox.y)): self.sonic.Yvel = 0 self.sonic.grounded = True self.sonic.jumped = False self.sonic.angle = tile.angle break (from characters.py) if not self.grounded: self.Yvel += self.gravityforce # Apply gravity self.Yvel = min(self.Yvel, 10) # Cap max fall speed self.Xvel = self.groundSpeed else: # Adjusting speed with some trigonometry self.Yvel = self.groundSpeed * math.sin(self.angle * -1) self.Xvel = self.groundSpeed * math.cos(self.angle) self.x += self.Xvel self.rect.x = self.x # Update self.rect with the new x coordinate self.y += self.Yvel self.rect.y = self.y self.hitbox.x = self.x self.hitbox.y = self.y I am using Tiled for mapmaking by the way, I'm not sure if that helps in my situation. I've manually added an angle attribute to the tiles currently in use and given them unique angles such as 20, 45, 90, etc. (which is why Sonic suddenly changes angle and jumps/phases through floor at times). With all that being said, can anyone help or offer some advice? Literally anything will be appreciated. Continue reading...
