Furnace is a ‘machine’ that converts primitive materials, found in the world of Floatlands, to more uncommon ones. This conversion is defined by internal recipes and it takes time to produce.

We have already added furnaces in the early stages of the development. Check them out HERE. They were obsolete and their design didn’t fit properly with other objects in the game, so we managed to recreate a furnace model with revamped background functionality. We also added new particles for the furnace as seen below:

Item Stacking


We’ve seen a performance drop whenever you wanted to drop a lot of items out of your inventory. To optimize this, I’ve created a world item stacking, this means that nearby items with the same ID get merged. To add sugar on top of it, I’ve managed to increase the size of a stack – the bigger the stack, the bigger a certain item is in the game:

We have decided to revamp the electric system used in the game – you can have a look at our initial electricity implementation with generators HERE. Our new direction is to have cables and the whole system will be more dynamic as well. I was mostly designing & planning though, so not a lot of programming involved. Still, I managed to finish up the cable connectivity – the cable is done with cylinder bending shader (wrote by ‘Metapyziks’), bending is done with cubic bezier (4 control point).

I also added capsule colliders through the existing cables, we need them because cables will be destroyable (either in build menu or by a player raiding). Still lots of work awaits though, I have drawn some technical sketches of electronic devices, Mito will then retouch those sketches and finally Andrej will make 3D models.

Villager buildings


In preparation for adding humans to Floatlands I started modeling buildings for their villages. So far I made two barns, water tower, granary and a central firepit.

When making models for a game we also need to make LOD models (levels of detail) which swap when the player is further away to save system resources and so the world can be fuller. I start by making the most detailed model first and then copy it and start removing details in two ways – by hand and by using modifiers, depends on what works best for the given model.

I usually make the last LOD from scratch, since it’s just the general outside shape. After that, larger models like buildings also need a collider model. This is an optimized mesh that serves as an approximation for the physics engine.
