Desert biome wildlife


Lately I’ve been focusing on desert biome wildlife, which will include rhinos, hyenas and lions. The plan for now is to have 3 biomes (normal, desert, snow) and each will have their unique wildlife. I already created the animals for normal biome – sheep, deer, wild boar.

So this week I finished preparing the rhino with animations and a ragdoll system and did most of the work on the hyena, which is still missing some animations and a ragdoll system. Mostly I’m just repeating the steps from the other animals to keep the process simple and efficient.

Procedural algorithm improvements and optimizations


The nature of Floatlands is now more believable for every island. Now it’s possible to spawn a dense forest or a huge area of nothingness. Another nice addition to an algorithm is that we can tweak generation in one file only with e.g. text editor.

There was a huge need of optimizing the whole world/island. I started to bake similiar meshes together (combining them), implementing better foliage shader and also implementing some features from Unity’s LOD system as well. A lot of work still needs to be done altough the performance has been increased significantly (from 40FPS to 150FPS on i5 6600k and GTX 1070).

Here is a quick preview of a “Father” island (the largest you can find), with all of the optimizations (LOD, draw distance, combined meshes, occlusion, …)

New weapons concepts


There will be a total of 3 weapon tiers. Tier number one will be the most basic craftable tier of weapons available. Resources for these type of firearms will be easy to find and easy to craft. The range of the arsenal varies from simple single shot pistols, assault rifles to powerful shotguns and even a grenade launcher. My task this week was to create a basic concept and sketches for the tier one weaponry. You’ll be able to craft them with the materials that you can find throughout the world. The weapons itself wont be very powerful, but they’ll get the job done until you find something better and stronger. Below are some of the weapons mentioned before, disassembled so we can visualize how they’re crafted.

Polishing animation code, adding behaviour


  • Behaviour tree has been growing for some time, it’s quite big now. I custom wrote almost all Action nodes, like Attack, Move to random position, Looking Around idle, Move to nearest Enemy and so on. I like having custom nodes because it gives me complete control.

  • Another addition is sensor/trigger for attack to deer. With this trigger/sensor I can know NPC has hit something, with it I can also query what it hit and apply damage & force.

  • The most difficult problem was trying to get animations to play nicely in Mecanim. I am still not sure if I am doing it right. I am smoothing a lot of variables over time now, which means animations are smoother but “sliding on floor” while walking can be seen in some instances.
