Volo Airsport v3.5 Released

Play Volo Airsport right now, get it through our website, the Humble Store, Itch.io or Steam.

See the Volo Airsport User Manual for instructions on downloading new updates.

New Release

It took bloody forever, but here we are! v3.5 is finally out, you get to play it, and we get to move on to multiplayer.

Lots has changed, lots has stayed the same. For all the details, check out this new featurette video:

Major changes:

  • Engine upgrade to Unity 5
  • Linux support
  • Physically based shading
  • New, more stylized terrain shading
  • Real-time day/night and weather cycles
  • Long range shadows
  • Completely revamped sound effects
  • Significant performance optimizations
  • More stability, more polish
  • New logo art

As always, let us know what you think about this new release! Leave a comment here, or better yet: discuss on the forums!

Progress, and a Thank You

(Shame on me, and egg on my face; this blog needs a new post so very badly.)

First, it’s video time!

This is a new level I created for the Think Design Play conference, where I was showcasing my game last month. It’s an 8km square island with a large peak and some valleys. I made sure there are plenty of interesting creases and paths to explore no matter where you look. It uses some assets from the Unity Asset Store: The Nature Pack and Cloud System to be precise, both of which I haven’t explored to their full extent yet.

A user on the Unity forums asked me for some details on how I achieved this look, and if you’re interested you can find my answer here: Unity Forums: What do you guys use for realistic terrains?

Anyway, the game was very well received and I got lots of great feedback*. A crazy amount of kind comments on the video, too! Thanks everyone.

I’ve been looking into the physics and aerodynamics again. The main problem I have with it is that the current components make it almost impossible to make the wingsuit aerodynamically stable to a satisfying degree. They lack some properties that make it hard to achieve this effect. When you play for the first time this is not too much of an issue, but after a while you can notice that the amount of oscillation and illogical stalls really get in the way. I’ll stress that I don’t want to get rid of the struggle for control, as that’s one of the most interesting things about the game, but right now some of the difficulty in control is unfair and unfun.

The last couple of days I’ve been experimenting with techniques that analyze a mesh for its aerodynamic properties. For example, using a matrix of raycasts to determine profile drag in high resolution:

Using raycasts to sample a mesh for its profile area in the relative wind.

This goes some way towards the techniques X-Plane uses for its simulation. It uses an offline phase in which it analyzes aircraft geometry in painstaking detail, storing coefficients of motion that can be looked-up while the simulation is running.

I can tell that this is not the way to go for Volo. For one, a typical aircraft has a mostly static shape, whereas a wingsuit flyer’s shape continuously changes in profound ways. The aerodynamic properties of someone curled up in a ball are completely different from someone flying in normal position. Doing this kind of analysis in real-time, say on a deforming cloth mesh and animated character would be very costly in terms of performance.

My current flight model might not be the most physically accurate, but one of its major qualities in terms of play is that every microscopic limb movement has a definitely noticeable effect on play. This nuance is exactly what I want to preserve, since it is what makes playing the game so much fun. So instead I will focus on patching the largest holes in the current system.

The other issue is that my brain is too small for the fancy tricks X-Plane does, or at least lacks the necessary training in aviation to pull them off within the foreseeable future . ­čÖé

 

Other than Volo development I’ve been freelancing a lot, and its finally started to resemble an actual job. I also have some things underway for the Unity Asset Store! Landmass is almost ready for release, for example.

 

Thanks for sticking around, everyone! Your kind words have motivated me to get back at it, I owe you one.

 

* I have this video of a kid playing and having the most exuberant reaction when he crashed into the completely faked ocean, he felt so cheated there wasn’t any actual water! He liked the game a lot though, came back a couple of times. I must remember to upload it.
