I Constructed One Thing with A-Frame in 2 Days (and You Probably Can Too)

By | October 3, 2017

A few months in the past, I had the chance to check out a quantity of WebVR experiences for the primary time, and I used to be blown away by the chances. Utilizing only a headset and my Firefox browser, I used to be in a place to play video games, discover worlds, paint, create music and a lot extra. All via the open net. I used to be hooked.

A brief whereas later, I used to be launched to A-Frame, an internet framework for constructing digital actuality experiences. The Hello World demo is a mere 15 strains of code. This blew my thoughts. Constructing an expertise in Digital Actuality looks as if a activity reserved for tremendous builders, or that man from Mr. Robotic. After glancing via the A-Frame documentation, I noticed that anybody with a bit of front-end expertise can create one thing for Digital Realityeven me a advertising man who likes to construct web sites in his spare time.

My crew had an upcoming presentation to provide. Usually we might create one more slide deck. This time, nonetheless, I made a decision to provide A-Frame a shot, and use Digital Actuality to inform our story and demo our work.

Within two days I used to be in a place to educate myself methods to construct this (slightly modified for sharing purposes). You’ll find a way to view the GitHub repo right here.

The end result was a presentation that was enjoyable and distinctive. Individuals had been much more engaged in Digital Actuality than they might have been watching us flip via slides on a screen.

This isnt a how-to get began with A-Frame submit (there are plenty of nice resources for that). I did, nonetheless, discover options for a few gotchas that Unwell share below.

Walking via walls

One of the primary snags I bumped into was that the digital camera would move via objects and partitions. After some analysis, I got here throughout a-frame-extras. It contains an add-on referred to as kinematic-body that helped clear up this concern for me.

Controls

A-frame extras additionally has helpers for controls. It gave me a simple method to implement controls for keyboard, mouse, touchscreen, etc.

Generating rooms

It didnt take me lengthy to determine methods to create and place partitions to create a room. I didnt simply need a room although. I wished a quantity of rooms and hallways. Manually creating them would take endlessly. Throughout my analysis I got here throughout this post, the place the writer created a maze utilizing an array of numbers. This impressed me to create generate my very own map utilizing an analogous method:

const map = { “data”: [ 0, 0, 0, 0, 0, 0, 0, 0, 2, 2, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 2, 0, 0, 0, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 2, 0, 0, 0, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 2, 0, 0, 0, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 0, 1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 1, 0, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 1, 0, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 0, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 1, 0, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 1, 0, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, four, four, four, 0, 1, 1, 1, 1, 0, 1, 1, 1, 1, 1, 0, 0, 0, 0, four, 0, 0, 0, four, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, four, 0, 0, 0, four, four, four, 1, 0, eight, 0, 0, 0, 0, 0, 1, 0, 0, 0, four, 0, 0, 0, 0, 0, 0, three, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 0, four, four, four, four, four, four, 1, 1, 1, 1, 0, 1, 1, 1, 0, 0, 0, 0 ], “height”:19, “width”:19}

0 = no walls
1 four = partitions with varied textures
8 = person begin position
9 = log place to console

This would permit me to strive completely different layouts, begin at completely different spots across the map, and rapidly get coordinates for positioning objects and rooms (youll see why that is helpful below). You’ll find a way to view the the rest of the code right here.

Duplicating rooms

Once I created a room, I wished to recreate a variation of this room at completely different places across the map. That is the place I discovered to embrace the object. While you use as a container, it permits entities contained in the container to be positioned relative to that mother or father entity object. I discovered this submit about relative positioning to be helpful in understanding the idea. This allowed me to duplicate the code for a room, and easily present new place coordinates for the mother or father entity.

Conclusion

I have little question that there are higher and extra environment friendly methods to create one thing like this, however the fact that a novice like myself was in a place to construct one thing in simply a few days speaks volumes to the ability of A-Frame and WebVR. The A-Frame neighborhood additionally deserves a entire lot of credit score. I discovered libraries, code examples, and weblog posts for nearly each concern and query I had.

Now is the right time to get began with WebVR and A-Frame, particularly now that its supported for anybody utilizing the newest model of Firefox on Home windows. Try the net site, join the community, and begin building.
