the new automatic step up mechanic isn't good for just slope transitions, but also means you can naturally step up on to short platforms

#gamedev #indiegamedev #indiegames

walking from a slope to a cube with a capsule collider poses an issue: the side of your capsule hits the cube preventing you from reaching the top of the slope

I implemented a step-up mechanic (essentially teleporting you up on contact), and smoothed it out over a few frames so it's not a jolt

implemented invisible walls. the work the same as normal colliders except they're authored entirely in-engine and are ... well, invisible 👻

#gamedev #indiegamedev #indiegames

massively improved the feel of terrain sloping, feels more natural now as opposed to being on a slip'n'slide

#gamedev #indiegamedev #indiegames

yes, almost always

improved static collision to handle slopes better. it's all coming together slowly but surely

#gamedev #indiegamedev #indiegames

much better, rigid bodies are now behaving almost as desired

still a bug where they don't wake each other on contact, but that's easy to fix

#gamedev #indiegamedev #indiegames

day 2 experimenting with rigid body physics, the cubes are merging to become sentient life forms

#gamedev #indiegamedev #indiegames

rigid body test, needless to say this didn't go quite as planned on the first try

but hey, at least it moves, that's more than I expected it to do

#gamedev #indiegamedev #indiegames

implemented basic colliders for objects, which means we can now actually step on this bridge

the dismount wasn't great, but progress is progress

#gamedev #indiegamedev #indiegames

next up on the physics train is terrain slope. simple but effective, and added a debug vis for it as well

#gamedev #indiegamedev #indiegames

time to start tackling physics, starting off simple with the good old (new) fashioned capsule and terrain snapping

#gamedev #indiegamedev #indiegames

another major improvement for the dev iteration cycle is being able to hot reload models

going to add a "Re-export" shortcut in to Blender as well to cut down unncessary clicks there as well

#gamedev #indiegamedev #indiegames

separated shadows from the view frustum so shadows of objects outside the view don't pop in/out

just need to add some culling for liquid tiles/volumes now

#gamedev #indiegamedev #indiegames

still wasn't happy with foliage, needed something. turns out that something was some ambient occlusion

packed 7 bits of density into the RGB/wind data for some cheap vertex AO

#gamedev #indiegamedev #indiegames

as I'm testing new features for my handmade engine, I often doodle random things

here we have SDF testing tar pit, next to the banana beach

#gamedev #indiegamedev #indiegames

things definitely don't always go to plan, especially when dealing with shader math

#gamedev #indiegamedev #indiegames

many hours later, I think I'm getting there with the look of the liquid volumes.

still not 100% happy with the foam ripples, but this is like the 30th iteration of trying different things

#gamedev #indiegamedev #indiegames

slapped together a little exp(-absorption * depth_diff) for the liquid volumes

dropped MSAA to make this straightforward, FXAA is fine for the art style

#gamedev #indiegamedev #indiegames

this would have be useful to know for my full-game 3D render I did a couple of years ago

added colour support for liquid. for volumes it's a simple RGB per volume

with map liquid, it's a single 128x128 texture per map tile for the colour data

#gamedev #indiegamedev #indiegames

in addition to the dynamic water volumes, also implemented a 64-bit water mask to map tiles

this can be easily painted and is intended for larger static bodies of water like the ocean

#gamedev #indiegamedev #indiegames

here's the water volume prototype in a more sterotypical scenario, rather than a floating cube

#gamedev #indiegamedev #indiegames

just for testing, triggers can do anything (could be a portal, or a trap, etc), here I'm just testing the a screen shake function with them for convinience

very basic prototype for water volumes

most features start this way and build up, iteration is much easier than trying to do a full-feature in one swing

#gamedev #indiegamedev #indiegames

added a little screen shake function, which also means I can show off world triggers as well now

now I can finally touch grass!

had an idea, foliage density only required the R channel, so used the G to encode a layer ID then doubled that (B+A)

now I can paint up to 255 different types of foliage per map (with overlap)

#gamedev #indiegamedev #indiegames

after a lot of iterations, I've got the foliage system to a point that I'm happy with
