Bambu Lab H3C. Tool Changer. Game Changer!
Bambu Lab H3C launches today. Nine independent PrintTools™ that allow multiple nozzle sizes in a single print. Powered by SwapTek™, Print-to-print tool switch only takes 6 seconds. Multiple toolheads with multiple possibilities. Print, cut, draw and deboss. All on the same machine. We built this machine. Now we want to see what you make with it. -------------------------- To celebrate the launch, we're sending one H3C Combo to a maker ready for it.

Another week of solver instability :( #godot #gamedev

Ok so this turned out to be a nightmare. Dont try to implement a physics engine if you can avoid it. I cant avoid it :(
Implementing XPBD and getting the same exact bug is really funny. its very annoying too but bugs keep boosting each other. bug A is on top of B and rises above but because theyre slightly intersecting B now thinks it can rise on top of A so A rises on top of B :( Wormelisks

Its actually so funny how irregardless simulation 1M physics bodies is just a pain in the ass because ofall the weird little interactions but it isnt slow. No whats slow and costing me more than half my frame time is DRAWING A SLIME TRAIL FUCK OFF

hm. not quite right.

I think ill have to actually implement an XPBD solver rather than my own hacky physics engine running this but I think I'm getting pretty close to a decent implementation. Handles ~100k bugs with plenty of headroom and can probably handle >1M with culling. #gamedev

One of the IMO cooler things im experimenting with is making all bug behavior work based on pheromones ... here's a heartbeat pheromone inspired by how biological clocks work. It controls when bugs move and sync up naturally between large crowds.

Because it is a pheromone, a berserker-like enemy could increase the local speed of such a heartbeat and make all bugs nearby act faster by simply having a faster theartbeat that everything syncs up with. Or the player could use a Rest pheromone emitting tower to slow bugs!

Also these are 500k worms at 120fps on a laptop. GPUs are cool

half a million worms #gamedev

Oh yeah I can make my bug swarm be worms too :o

Having lots of fun doing game dev again
