#Losing My Marbles!
true mauve
we started with jbullet, then bullet, then ODE, and finally settled on Jolt
keen plaza
yeah damn
true mauve
both bullet and Jolt have modern java bindings (both by the same guy (also the same guy who has a usable jbullet fork 
)) but jolt just seems better and more modern
keen plaza
thats wild for a single item modfest like this
true mauve
Rayon used bullet, but it's no longer updated
keen plaza
yeah
patbox updated rayon to 1.21.8 but its still not amazing and it switched hands so much nobody really knows the full workings of it
narrow dagger
Usually our fest mods get to like 75% of where we want them to be before dev time ends, and somehow despite the horrors™ required for this one we’re like 90% there and still have a day lmao
abstract grove
Enough time to make it server side
keen plaza
~~Enough time to make it server side~~
real
narrow dagger
Lmao
true mauve
I went all in on data for marbles, I really like how it turned out
keen plaza
the geometry of the marbles is quite a bit more complex than the cubes of physics toys with rayon and it seems to perform better
narrow dagger
Insane data formats my beloved
true mauve
you can do any of these things any time a marble bounces
narrow dagger
Any number and combination*
true mauve
@ember trench if you want to make the hama marble real it's fully data driven
narrow dagger
^
Soon™ we’re gonna have marble rendering that supports a single texture that rotates as the marble moves, it’d be perfect
keen plaza
this is fine
paper forge
does windburst activate redstone that sounds like it could be problematic for the fest
true mauve
"marble types are basically just a component map" - statements dreamed up by the utterly deranged
narrow dagger
We won’t be giving those out in the fest
But yes, they’re just normal wind bursts
Same for explode
No tnt marbles in the fest, but they do in fact explode
true mauve
post-fest I'll likely split the physics into an independent library
keen plaza
what would the process for loading 3d models like a cube into a system like this be?
keen plaza
what would the process for loading 3d models like a cube into a system like this...
and how many degrees do I need to complete first?
true mauve
not possible, all marbles are a single quad
keen plaza
I dont mean within the datagen constraints, I mean within jolt to jvm bindings.
abstract grove
Any?
keen plaza
yeah I think I have a lot of reading ahead of me
abstract grove
You would just need to render it right
keen plaza
thats easier said then done, especially when I have zero clue how mc rendering actually works
abstract grove
Well, assuming you have item model just use that
keen plaza
2400 marbles before lag got unbearable, pretty good, think it was also more render than physics too
I was only getting ~400 on rayon
with basic cubes and that was server before client
abstract grove
Client lag or server lag
keen plaza
Client lag or server lag
with marbles I think it was actually more client lag
id have to do further testing but it seems quite interesting
true mauve
we're also hoping to add flywheel compat if that port is done in time
keen plaza
for create?
keen plaza
oh I only know its part of create
I havent looked into it
ok yeah that would be very interesting
sonic osprey
noooo my marblesss!
narrow dagger
is your marble running? yes? you better go catch it then.
fringe smelt
is there a way to push marbles?
narrow dagger
is there a way to push marbles?
punching gives a moderate amount of velocity, and just walking into them nudges them
there's an item tag for items that add more velocity when punching, too. sticks, blaze rods, breeze rods, and swords do more
fringe smelt
what about when used?
narrow dagger
right clicking picks them back up. they spawn with no velocity, but we're gonna have a solution for automating marble runs
narrow dagger
what are you thinking
fringe smelt
when using the confetti gun it would push marbles, like add force to them
narrow dagger
is the confetti gun purely a visual effect or does it do physical things when you use it too?
we could probably add compat for that either way
fringe smelt
the base gun just shoots particles, but there are 2 enchants, 1 recoils you back and the other shoots a firework
narrow dagger
ah. just checked and right now fireworks dont interact with marbles at all
abstract grove
Your gradle thing doesn't seem to work hm (wanted to check how much was needed to make it a ProjectileEntity )
regal bramble
ah. just checked and right now fireworks dont interact with marbles at all
do you know if explosions push them around?
narrow dagger
do you know if explosions push them around?
they do
latent hemlock
How to make the marbles?
true mauve
the marble maker
ember trench
I think the crafting is bugged rn
narrow dagger
Yeah another mod was breaking certain datapack things, I think it’s been fixed now though
abstract grove
Btw should I look into my own implementation for compat or do you think using you coukd move to projectile entity
true mauve
projectiles come with a lot of implications that I don't think make sense for marbles
abstract grove
"Bare bones" projectile entity doesn't do much
And some things you already have (like owner)
Default hit detection can be ignored
But will look into handling it on my side then
abstract grove
Only issue is that player might pick it up too quickly / by accident
And since it's final, I can't hijack the interaction
Hm
paper forge
cant you set the pickup delay to whatever you want
abstract grove
MarbleEntity has no code for that
true mauve
the funny
true mauve
Only issue is that player might pick it up too quickly / by accident
I don't think that's a big deal honestly
narrow dagger
Nice

hey uh a marble max might be a good idea
and physics errors shouldn't crash
narrow dagger
we're gonna make them have an expiration timer so they don't just build up everywhere
true mauve
and physics errors shouldn't crash
what errors
narrow dagger
and physics errors shouldn't crash
can you explain what you mean by that
true mauve
hey uh a marble max might be a good idea
the game can handle over 1000 without getting too bad. it's no different from causing lag/crashes from spawning too many normal entities

the physics engine throws a hard crash if there's too many marbles
narrow dagger
jay doesn't that happen if enough unique geometry is being used for marble collision too
again, it shouldn't be low enough to ever run into during the fest, but we had that happen when debugging that leak
autumn river
whatever it is we just hit it
true mauve

I think it could but the limits should be way above what you could reasonably hit
oh you actually crashed the test server with this
how many did you spawn
narrow dagger
yeah :ioa:
minor burrow
true mauve
user error

true mauve
2000 is lower than I thought but still two orders of magnitude more than there should've been
hazy shale
Spawning 2000 of any entity is going to cause problems
narrow dagger
yeah
true mauve
narrow dagger
should we do something about that, like making it so that if more than 10 marbles share a block space they don't collide with each other until they leave it
true mauve
not an easy thing to check
hazy shale
The most that realistically would be at the fest is like 100 marbles
true mauve
we need to see what the actual limit is and maybe turn up the cache if it's low
narrow dagger
The most that realistically would be at the fest is like 100 marbles
entirely depends on the free build area, tbh
lets say we have 30 marbles in our booth showcase, everything else is uncertain
keen plaza
the physics engine throws a hard crash if there's too many marbles
How many did it take to do that? I've got 7000+ without engine crash.
Broke the client but server was still fine
