Parallax scrolling examples1/11/2024 Example 3: Horizontal and Vertical Parallax Scrolling While Following an Object The player’s ship never actually moves up the screen, but you still get a sensation of fast-paced space traveling. This type of parallax scrolling allows us to simulate the depth of space while also simulating forward movement. The static background does not move, and each successive layer of stars grows larger and moves faster, with the final layer of stars ultimately determining the vertical speed of the focal point, the player’s spaceship. This scene features four background layers: a static black background and three collections of stars at different sizes. (We will see just how important this is in our third and final example.) ![]() The most important thing to take away from this vertical example is that parallax scrolling works in all four directions along the x-and y-axes. There may be more efficient ways to create a star field, but parallax scrolling gets the job done. While parallax scrolling is most often used with horizontal backgrounds, it can also be used in vertical scenes, as in this space shooter example. Any foreground layers would move at a speed greater than 5. Moving at a speed of 5, then each successive background layer would move at a For instance, if the focal point is Layer 3 and is Then it would be best to define layer speeds by reading the current speed of Multiple scenes with varying quantities of background and foreground layers, Pre-determined speeds without referencing one another. There are several ways you can implement this kind of So it moves more quickly than the focal point on Layer 3. Layer 2 moves more slowly than Layer 3, and Layer 1 moves more slowly than Layer 2. Would be the focal point of the observer, and would also dictate the speed of Platformer, then our player object would exist on top of Layer 3. To the screen as well as its movement speed. In thisĮxample, the number of the layer defines the order in which the asset is drawn The four layers that make up our first scene. Repetition as the same asset scrolls indefinitely. Since the layers are tiled, this will help to prevent too much obvious Game window, we can prevent the entire asset from being visible at any given By using background elements that are larger than the The game window is 600x300px, and our art assets each haveĪ width of at least 600px. For now, let’s focus on the basics of parallax scrolling without worryingĪbout any player movement or shifting views.įirst, let’s break down the individual elements andĪttributes of our scene. The various background layers move at pre-determined speeds along the x-axis. ![]() Street at night that features horizontal scrolling with no interactiveĮlements. In our first example, we have a very simple scene of a Results in an illusion of depth that makes a 2D scene feel more immersive. ![]() Background objects move slower than theįocal point while foreground objects move faster than the focal point. Game camera stays focused on a particular point or object, while the background The observer, in this case, is the player, and the Into different layers, it is possible to control the speed and position of Is achieved in modern video games, but instead of a multiplane camera, scenesĪre assembled with multiple layers and a single game camera or view.īy dividing the background and foreground elements of a game To the perceived distance from the camera lens. Were able to create a non-stereoscopic 3D effect that created the illusion ofĭepth by allowing different art assets to move at different speeds in relation Takashi Nishiyama’s Moon Patrol is widely credited as theįirst game to feature 2D parallax scrolling, but the technique existed in Of the observer, as scaling the object would require a change along the z-axis. Only an object’s speed and location will change with the position Parallax scrolling, the observer’s position only changes along the x- and y-axes. Observed object due to a change in the position of the observer. Parallax is defined as the apparent displacement of an Click the demo to activate it, then use the number keys to switch scenes and the arrow keys to move the spaceship (for the appropriate scenes). Try the demo below to see scenes that use horizontal, vertical, both, and no parallax scrolling. Into your skill set, regardless of your current skill level. Several methods of implementation, in such a way that you'll be able to confidently and successfully introduce parallax scrolling In this tutorial, I'll cover the fundamentals of parallax scrolling, along with ![]() Tried and true staple of gaming that will greatly increase the immersion and Shooter or a horizontal side scrolling platformer, parallax scrolling is a Parallax scrolling is a simple and effective way to create
