Dev Update – Parallax!

I’m sure you’ve played a few 2D side-scrollers. I’m sure some of those implemented parallax scrolling as well. If you don’t already know, parallax can be described as follows:

Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines. As the viewpoint moves side to side, the objects in the distance appear to move slower than the objects close to the camera.

One great example of this is standing in a forest, looking out and seeing many tree trunks. If you focus on one tree as you side-step in one direction while looking forward, you’ll see trees farther away are moving slower and trees closer are moving faster in respect to the one you chose to focus on. Making sense? Good! Anyway, I wanted to show a quick clip of what our parallax looked like.

Parallax in the flesh!

Neat, huh? The process behind this is actually remarkably easy. Each “layer” of art gets its own parallax factor. This is just a multiplier that will be applied to the speed of the camera moving. If the parallax factor is less than 1 but greater than 0, the layer will move slower than the camera (such as the ocean at 0.8). If the factor is negative, they will move faster than the camera (such as the light posts at -.1). The pavement, pillars, and the car are all on the same layer as the player, so they move at normal speed (essentially 1.0).

Also, giving a shout-out to GifCam which was used to make this gif. Super easy and free (donations accepted!). Pretty much as good as the Snipping Tool for Windows. Will definitely be using in the future for posts here.

Dev Update – Adjusting Art Style

Before making this post, I realized I didn’t have a category for simply posting updates on work that wasn’t tied in to some release or patch notes. Well, I guess now is as good as any to introduce Development Updates! For the premiere of these posts, I wanted to show a little teaser of our current and possibly future art style we’ll be going with.

Pretty sweet, huh? You can thank Stewart Leith for that and check out more of his work at his own blog. Those waves are animated, too! Obviously, we went with a bit of a retro, pixelated look. Nothing wrong with that, but it turned out to be quite limiting (just check out Stewart’s stuff, epic potential!). So yesterday, he sent me a simple concept of what the new look could be, changing the game into more of a platformer than a runner.

The planned style for the near future.

Much more painterly, interesting to look at, and putting some parallax onto these scenes is gonna be a treat. Maybe I can get some gifs up then to show that off. Might even play around with the current scene to test it. Anyway, I hope that has wet your appetite for a bit of content for now. More to come later this week!
