i plan on it.....which gives me the though....could you make half the dwarves fight the other half? sort of a turnbased multiplayer game? at home?

graphics, but not things like physics and item spamming....oblivion has a lot of that lol

"look up item duplication glitch on youtube for obilvion"

Did that, then I looked this up again.
3000 barrel boom in crysis
Crysis has an editor. ;)

edit: fixed linkz

that was cool....but the barrels didint fall until after hit by your guy. they seemed to just stay in midair until interacted with. thats not constant physics.

Well yeah they had to be messed with... In the game, almost every building is collapsible. If it enabled physics on everything long before being seen or touched, crysis would be even harder on the CPU than it is now.

Optimization. It's a good thing.

everytime i talk about phyics games i die a little inside knowing i cant play one with perfect physics.

i mean to the point where there is actual natural weather type physics with heat and pressure and stuff in a large city where you can build and tear down building reaistically

Welp, the only solution is to learn as much as possible about the math behind IRL physics, then make your own physics engine with "100% real physics"*

*Minus the optimizations you need to make because simulating realistic atoms and the interactions between them is quite simply impossible with anything resembling modern technology.

not impossible, just not something that anyone would pay for

... No, it's just impossible.

Do you realize just how much data would be needed to simulate, say, a spoon at the atomic/subatomic level?
Let's say it's a really small silver spoon and weighs just five grams.
MATH TIME! (I don't feel like carrying through the significant figures, so I'm just doing these based on what the calculator spits out)

grams -> mols conversion
5.000g Ag * 1mol Ag/107.8682g Ag = 0.046352863958 mol Ag

mols -> atoms conversion
0.046352863958 mols Ag * 6.022 141 79 E23 atoms per mol = 2.791435191279 E22 atoms Ag
That's how many individual atoms you would need to represent... about twenty eight billion trillion.

So how much data would need to be stored? Let's say each atom can be represented with a VERY conservative four bytes.

2.791435191279 E22 atoms * 4 bytes per atom = 1.116574076511 E23 bytes
(111,657,407,651,189,136,371,979.87914881 B) /1024
=(109,040,437,159,364,390,988.26160073126 KiB) /1024
=(106,484,801,913,441,788.07447421946412 MiB) /1024
=(103,989,064,368,595.49616647872994543 GiB) /1024
=(101,551,820,672.45653922507688471234 TiB) /1024
=(99,171,699.875445839086989145226892 PiB) /1024
=(96,847.363159615077233387837135637 EiB) /1024
=(94.57750308556159886073030970277 ZiB) /1024
So just to store the data that represents five grams of pure silver (shape really has no meaning) assuming a measly four bytes per atom, you would need a hundred million million gigs of storage.
So... you would need a billion (or so) of the fastest supercomputer in the world to fit all the data in to memory.

For just a small, five gram, silver spoon.

Sorry, buddy, but it's not going to happen this century.

I'm not going to bother getting into how many years it would take to perfectly simulate a full second of the physics within the same spoon.

nice, but i was talking about "i mean to the point where there is actual natural weather type physics with heat and pressure and stuff in a large city where you can build and tear down building reaistically"


atoms like you showed would be insane and quite frankly, impossible, as you would need more mass then thing you are trying to simluate, so simulating a city would mean you would need a city-sized computer or more
