Topic of the week

Optimization

Where to begin?

"VR is highly dependent on draw calls. If you can get your head around that, then you're sweet. But everything comes down to knowing how to read the frame debugger, and stats panel when you run the game." Recent quote from Thomas Coromandal SAE Sydney

Code Optimization

I know the structure of my code is to put it bluntly, crap. I'm keen to learn how to clean this up and I know from my Diploma that State Machines are the way to go. Along with optimizing Draw Calls, I'm going to focus on re-writing, and commenting all of my code this week.

Mapping my new Systems and States

How to Render 10,000 Animated Characters With 20 Draw Calls in Unity | Jiadong ChenThis post was first published at Medium This is an English translation of a blog I wrote in Chinese in 2017. Although the original blog was a few years ago, I found this article very interesting, so I decided to translate it into English. 0x00 Introduction I think a lot of game developers hope that the more objects they can render in their scene, the better.

Draw Calls Drastically Reduced

Using the Unity profiler, I looked at the area I was having high draw calls, then turned off objects in that area to see where the issues were coming from. It was all coming from my underground mine track, which had hundreds of different meshes. The solution was to use a free Unity Asset called "Simplest Mesh Baker", and I combined similar objects into a single mesh. The disadvantage being baked lighting would no longer work as the light maps now have issued, I also can't move position of meshes once combined. My draw calls however have dropped from over 1000 to around 200-300. Most of the scene now runs very well with quest standalone, still some work to do but big progress!

Just add some particle effects, a quick script and presto, can't wait for Halloween!

Missiles Added

The final modifications for a while. I've suffered from a broken USB cable which is going to prevent me from doing dev work for a while. I'm not able to test what I'm doing when I make changes so it's kind of like flying blind. Looks to be all I'm going to be able to do this week, I still need to re-write the code but it's not a good idea to do that without being able to test as I go.
