SortaBomber - Explosion Physics

SortaBomber

Blow up stuff.

This is my replica of Roblox's "welds" system. This groups static objects together, e.g buildings, but when hit above a set speed, the building will break.

Controls

(RIGHT) click and drag to look around.
(LEFT) click to fire explosives.

Improvements

I modified Physijs to work with the WASM version of Ammo, which has improved performance by.. a lot. It's now possible to simulate a few hundred blocks now without any lag. I would update the car physics game with this, but there are a few underlying problems with Physijs itself and Ammo (I spent a few hours getting collisions to work correctly), which means more bug fixing :/

How it works

Objects are first added to a parent object. This makes them a compound shape. Explosions are calculated by their position and force. The overall group has a set "strength", and this is reduced by repeated explosions, amplifying the damage done. The velocity of an object is reduced by the distance it is from the explosion, and increased by the explosion force. Objects farther away from the bomb move slower, and vice versa. Because objects cannot move independently from their parent, the ones nearest to the explosion are ~~orphaned~~ and made dynamic. Simply removing the object from the parent and adding it to the scene doesn't work, so I clone the object (probably a bad idea) instead.

Enjoy!

Play it!

Not working?

This Repl uses experimental technology that may not yet be supported across all platforms and browsers. For the best experience, use the following:

A home desktop/laptop computer, some schools may block some files
Chrome 89 or as recent as possible

What may be the issue:

WASM
Module Web Workers
WebGL
ES6 (Don't use Internet Explorer :sob:)

hot new top

I have found....the unbreakable thingy:

Behold in all it's grandeur:

Still here!

So many explosions I've made the other orchid blocks go away!

Now it's all alone! :(

@Bookie0 Behold...

the parent object!

@tussiez *gasp!

@Bookie0 I see you use ChromeOS. It seems everyone on replit does.

@mollthecoder i uh don't. I use macOS what makes you say that?

@Bookie0 My mistake. I said that cause the cursor was the same as Chrome OS's cursor. It seems they have the same cursor.

@mollthecoder ah I see np lol

@Bookie0 lol @mollthecoder @tussiez

@mollthecoder I'm on Ubuntu 20.04 and I also have the same cursor

@JWZ6 super ping

@FlaminHotValdez Yee

@tussiez lol

@mollthecoder I am on a school chromebook for coding in school and a bunch of other people probably are

@personmandude Yea

Let's honor the people who play this without a mouse.

@LaneMartin This is how the Germans bombed London:

@LaneMartin

"Can you see where it's going to land?"
"No."
"Just spam it ig"

@LaneMartin I played this without a mouse.

@AryyanVineeth o_o

I like how you can launch bombs from the top, change the angle, and view it like a 3D bombing simulation

@Soccer135246 oh wow I can hit them from under and they still move...

@Soccer135246 ikr

This is really cool, with nice physics, the only citicism about it I have is the update ing of physics, it looks like a bomb only updates blocks around it and dosn't account for physisics that was not in the radious of the blocks

This is pogger @tussiez

@LaneMartin pogger

@tussiez you're an imposter

@notTussiez lol notTussiez lol funny name

@LaneMartin Trust me, he's not the real one

@notTussiez lol ok hehe

Wait, firstly, it says:

Assuming it is "Physics" with a "C", How in the "PHYSICS WORLD" does this make sense?:

Oh or probably it is just the subject of "Physijs" not "Physics".

Well, IMMA call Mr.Neil deGrasse, this can't be tolerated. @OldWizard209

lol @IronStarkMan

@OldWizard209 Well... ~~Roblox exhibits the same behavior, doesn't it?~~

Ball go boom

@FloCal35 lol

@FloCal35 Booom

@FloCal35 my eyes

Which library was this built with?

@novaflippers Threejs (WebGL) and Physijs (physics, using Ammo --> pybullet)

@tussiez ooo ty

this is basically roblox 2007

the ball is from crossroads roblox lol.

@PyCoder01 Heh

*throws a literal bomb at the tower*
*blocks explode*
*top of the tower doesn't fall down*
Ah yes, physics.

Or is it fisix?

@FlaminHotValdez This is normal Roblox behavior

bumbs go brrrr

Brr @ChopSueyMaster

@TheC0derGirl

pogger

@tussiez

poggers

@TheC0derGirl Super pogger

@tussiez super duper pogger

Aymazing
Pog

@LingWu1 Ay

lol @tussiez

solid proof that green is better than purple. Time to spraypaint my room

@FlaminHotValdez 100%

COME ON @tussiez ONLY 4 MORE TO GO:

@LaneMartin boi...why do you care about cycles? they are useless internet points. Also that is weekly...In the long run, RayhanADev is more than 500 cycles ahead of tussiez anyway

@FlaminHotValdez i know that

@FlaminHotValdez Yee

Neither the window in this repl or another tab will load... How long should I wait?

@alpha2442 ?! Press Run?

@tussiez even if I press run it doesn't work bruh

@alpha2442 Are you using a personal not school, desktop computer and Chrome? A lot of my Repls use experimental technology

@tussiez yeah I'm using a PC and also chrome

@alpha2442 Latest version? Huh, send me a screenshot of DevTools' console and Network tab

@alpha2442 Looks like this:

@tussiez i restarted my tab and also closed all of my tasks i don't need in windows task manager and it seems to be working now because the program needs quite a bit of power to run apparently

@alpha2442 True - it's a 3D physics engine

tower gravity when?

poggers 100

@FallenAngel6 pogger

This needs a lot more upvotes

@LaneMartin Oke

@tussiez yay

The dust clears

It still stands

@SudhanshuMishra The all powerful

What are you doing here you should be in mojang

@SudhanshuMishra Heh

You should add an option where you can have more than 1 tower but the maximum in 10 so it feels like bombing an entire city and not just a puny building.

the second slider's snap is 1, not .5, which makes the bomb explosion numbers funni

@RahulChoubey1 Funni number
