Good time of the day! Tell me please. I'm making a side view game, a player on a bus. There is a Parallax Background() function that is responsible for parallax. How can I synchronize it with the movement of the bus? I tried to call the function when the player presses on the gas, but it looks terrible, because when the player releases the gas, and the bus is still going, and the background immediately stops. I want the background to smoothly gain momentum and stop smoothly, depending on the player's speed. I am attaching an archive with a level.

you would need to multiply each background layer's scrolling speed by the player's current speed

Since it looks like you're using physics, you could probably use GetSpritePhysicsVelocityX(). Alternatively, you could get the player's speed by subtracting the player's x position at the last frame from the player's x position at the current frame, IE



Just note that the 2 methods will return different values, since GetSpritePhysicsVelocityX() returns units (pixels) per second and the alternative method would return units per frame.

note that images need to be power of 2.
