If there’s one thing that I’ve learnt about this digital artefact, it’s that creating VR is very time-consuming and a little difficult! My last blog post depicted the first couple of trials and errors of trying to create VR and I’m pretty sure my greatest success was building a sidewalk.
However, I’ve spent some time following this tutorial series, as I was able to learn the basics of Unity quite seamlessly, and follow it through. This has led to the changing of my aims, as I was aiming to build a house or a building or so forth, now I’ll be following this series to try and build a virtual city, to which you may learn how to use Unity from.
So, I had originally started this tutorial series, and I initially stopped after building a sidewalk and a couple of buildings but because I managed to learn the most with this tutorial series I aimed to follow it through.
So this is where I left off, I documented the beginning of this in my previous blog post, which you can check out if you’re interested.
To begin, one of the most important things I’ve learnt about creating VR in Unity is the use of cubes. These can be accessed by going up the top to Game Objects – 3D Object – Cube. Basically everything I’ve ever made in Unity is with a cube, this is because I’ve been creating more structural objects like buildings and sidewalks etc. but for beginners like myself, cubes are your best friend.
I made the early mistake of using the manual scale button to resize my cubes (The 4th button on the top left), this basically led to everything being uneven, and made it extremely difficult to join buildings to sidewalks and so forth.
On the right under Inspector, I started playing around with the position and scale, which you can see under Transform, this takes a little time getting used to but it definitely makes the whole creating process easier as everything is even and can connect with each other. I always set the position for the x, y and z axis to 0, this became a habit from following the tutorial series as he also did the same thing and it makes it easier to locate your new object that you’ve imported onto the screen.
Moving on, I cheated a little bit by duplicating the first small building (Command D) and dragging next to the first using the second button on the top left. This gave me two buildings that were exactly the same. On the tutorial series he has a range of textures available, these are downloadable and I imported them in order to create realistic looking shops.
This is what they looked like, you may have also noticed that there are buildings on top of my shops, basically I duplicated them (Command D) dragged them on top of the bottom buildings and dragged the textures that I downloaded onto the cube.
The city now looks like this. I did adjust the scale of one of the buildings, changing the y-axis to 7 so that it was slightly taller. Next I duplicated the whole building on the right and dragged it over to the blank spot on the left.
And there we have it, the start of my very own virtual city. The first few trials and errors (which were increasingly frustrating) were incredibly important in understanding what I was doing wrong and how I could fix that. You may remember I was having a little issue with placing objects above/below one another; this was easily fixed by understanding the scale options and positioning the objects to 0, in order to have them even with one another.
For my next blog post, I’ll be following the next couple of tutorials and attempting to build the entrance to a subway station, stay tuned!
