How do you get a certain sprite to stop moving when it gets to a certain level on scratch?

To stop a Sprite from moving when it reaches a certain level in Scratch, you can use an if-else block to check the sprite's y-coordinate. For example, you can use the condition if <y position> < [desired level]> then to stop the movement by setting the sprite's velocity (or movement variable) to 0. Additionally, you can use the stop block to halt any ongoing movement scripts when the condition is met. This ensures the sprite remains at that specific level.
