Oh my goodness crazy stuff

make a source engine mod that makes all the props way too bouncy like this and play hl2 with it

I wonder what would happen if you tried something like this in GTA V. With speedrunners having uncapped FPS, the effects I've seen range from missions instafailing to ladders becoming catapults

that was my thoughts exactly expecially with the ragdoll physics.

I mean, its the same game engine so there's no surprise here

I like how the physics are more lifelike in some parts and beyond broken in others.

I'm pretty sure physics simulation is scaled/proportioned to tickrate, but I can't tell if it A) doesn't, or B) the simulation (read: the faster approximations of physics aspects actually used) break down as the tick rate departs expected ranges.

Maybe. Usually when physics engines are accelerating something they multiply the acceleration/ velocity by the time the last frame took to complete in seconds so everything scales properly no matter what

@@disk0__ could be worse could be a case of some part of the physics simulation is scaled/proportioned to the tickrate (also part of the Frame rate) and some is not. Iknow there was a few games that ran fine in 30 and 60 FPS but if you set the FPS cap to 120 and ran it from that Physic would break in some cases because some physic calculation was done at 30/60 times a sec and some would end up been done 120 times a sec. and that would just break.

You’re partially correct. In the source engine, whenever a physics object touches any other object that it cannot pass through, it is pushed away. It is not stopped, no, it is pushed. So for example, if you take a box and drop it on the ground, the box doesn’t actually stop as soon as it hits the ground, instead it slightly clips into the ground and gets pushed back out, making it seem like it stopped. On low tick rates, this would make the object either sink, or bounce weirdly as the object isn’t being pushed away instantly most of the time. However, on high tick rates, the check for whether the object is clipping happens too much, causing it to, well… go absolutely ape shit. You can actually see this occurring even on default tick rate, depending on certain conditions. If you’ve ever seen a physics object in a source game slightly dip into the floor or another object, that’s the push failing to occur (this will generally be caused by a performance dip, or something else). The only objects that don’t follow this rule in the source engine are: entities and ragdolls (technically ragdolls are entities)

​@@disk0__ Numerical simulations are not stable under all step sizes\tick rates. Pretty general statement but I'm sure that's to blame here

That's something that sounds like it's straight out of portal 2.

Everything about this clip is hysterical

the combine turret and the aperture turret are reskins of each other so playing portal on a high tick rate would let the same thing happen

given what seems to be going on with gravity, i can imagine some puzzles being way more exploitable and others becoming impossible, but with the speed cap it might mantain some degree of stability.

from personal expirence airboat vr is PAIN.

Oh shit? How do you do vehicle stuff like that, is there documentation?

Oh fr?

Yeah, it's a cool feature. Fun fact, actually; portal 2 has some base source entities that are related to HL2 entities, and one of them is a generic vehicle. The original player based controls are completely broken, but the IO based controls still kinda work. Ended up just barely restoring the jeep in Portal 2, was really neat.

I bet that will crash the game

@@Pacca64 you can spawn airboats in portal 2 without sv_cheats on.

tbh with everything else in the video it was just a minor note.

I didn't know i needed this until I saw this comment

I remember in one of pine splash's other videos he said player vehicles have a flag that makes them land right side up, and there's a special exception so the car can land upside down in sandtraps when it's dropped. Maybe it's just the physics trying to nudge it right side up and going haywire?

Most calculations do seem to be deltaTimed - just certain contact modifications and velocity applications not

A bunch of shit breaking, THEN an explosion to cap it off.

expecially with all the loose props and explosions and such.

All i found while playing with high (acceptable) tickrate of 100 that it can break some part of the scripted event and softlock the game, example the undue alarm chapter in ep1 where you on an elevator with alyx to goes down to the core, the stop at the stalker section doesnt work even you put energy balk in the reactor thingy, the stalker simply does not spawn and the elalevator stuck in place.

@@doggobind Well if my life is nothing and serves no purpose, I have nothing to lose! The pfp stays!

@@doggobind whats the context of all this statements ? sorry i seem to be missing something...

I mean wouldnt you be panicing?

It’s actually to do with how the engine handles objects touching each other iirc. Basically the objects touching each other aren’t a hard “don’t go in this” thing. Instead, objects resist each other like magnets, but slightly clip into each other leading forces to push them out making it seem like they’re stopped. But the high tick rate causes them to push too much, leading to, well… chaos. Also, entities (including ragdolls) are exempt from that kind of physics simulation (it’s why you can’t pick up ragdolls or do a lot of other physics-based things with them)

Broken trigger. It wants to go to a specific position and drop the APC. But the APC is gone. So it derps. You can do it legit at the lighthouse, if you destroy one of the troop carriers the drop ship derps and just starts doing loops trying to figure out where it’s supposed to go next.

@@FenekkuKitsune I was mostly just goofing, but that's a really cool piece of information too! Had a feeling it had something to do with breaking the script. Makes me just imagine the dropship turning around and going "Gordon, what the HELL!? Now we need to re-shoot this scene AND get a new deployment pod!"

By default, -tickrate is at 66. In his low tickrate video, it was 11. This time, it's set to 400, not a multiple of 11

@@tristenarctician6910 So 440 would work better?

While the gameplay remain the same, higher tickrate break some part of the game and soft lock you. I tried playing with 100 tickrate (cs source high tickrate standard) in episode one, the elavator section with alyx did not work correctly, when revert back to 66 it worked flawlessly.

@@frozenheartedgiant8330 maybe, though I tested a 500 tickrate game and it appeared to an amplified version of tickrate 400
