Valve tried to stop speedrunners and in turn accidentally created one of the most fun speedrunning tactics.

heck they even created a new genre of maps.
Imagine giving Pinsplash a power of Shounic to illustrate his explanations.

It's weird how they messed up coding the speedlimiter despite having a pretty robust one in HL1. The systems are different, sure, but I guess the intern who coded it that day totally winged it. At least it gave us one of the coolest movement techs in gaming.

Because the one who added the one for HL2 wasn't named John Carmack/Romero, whichever.

My favorite thing about this channel is that Pinsplash sounds exactly like a Valve developer commentary node.
the car is ready for you now dr. freeman
Oh, and by the way - huge thanks for subtitles. It's very important.
Debugging hl 2 code for understanding how glitches work. Marvelous job. Thx

i always wondered how bhopping worked...interesting video! I liked it!
great video! It's great to have resources like this explaining the logic behind weird wonderful mechanics
As a person coding gmod addons, hearing code related stuff like normalized vectors puts a smile on my face
hey pinplash I don't know why but your voice is very comforting and I like your videos, they speak very loudly to my adhd.
You explain everything so well! Keep it up man!
How does one 'walk' in HL2 while wearing a HEV suit? Is it some separate, normally-unused keybinds or something? You mentioned that being HEV-less forced you to walk, but in some of the footage (mainly 2:10 ), it's implied that the player is in the HEV suit (mainly from the UI), but are still somehow walking. This video also gives me a terrible idea: Beat HL2 while going as slow as possible (while constantly moving - no waiting 8 hours then beating the game lol).

@@vladls Wait, seriously? That's a keybind? How did I not notice that while going through the controls? I guess it's a bit of a weird and obscure one since alt is a bit hard to press with one hand while also pressing a directional key :P

super in depth video about my niche interest? yes please!
I would like more in-depth code analysis of source or other games pls.
cool video, well explained
Omg! Another pinsplash video! And with captions! I love you for captions.
This is one of those VERY rare videos i never knew i wanted to see
When you landed one of the big jumps KZread shat itself and restarted my playlist. I was very confused
I never knew I needed something like this to know
Thank you Mr Pinsplash for teaching me the ways of Half-Life.
I guess the Certified Valve Polish (TM) isn’t applied very much for patches. This wouldn’t have slipped through the cracks in mid-stage development… right?
Why didn't they just clamp all the speed vector components (separately) after all these calculations, and recombine it back?
I want to put something like ABH into Alien Swarm: Reactive Drop, but the player not being able to jump causes some problems with this.
Great material for falling a sleep
We give a player a forward speed boost when they jump. But now, we want that speed boost gone. So, do we just remove the speed boost then? No, we surround it by more spaghetti logic
subtitles took 2 times more than previous video about episode one wtf
So, I'm just curious, in terms of MPH, what is Gordon's max possible speed with ABH?
@NoahGooder

well if you had an infinately large map to test it you could probably reach somewhere in the range of 2147483647 units per second.

Player's movement speed in HL2 is hard capped to 3500 HU/s. Which you can reach pretty quickly with ABH.
Honestly, I would love if you could implement some of your stuff into HL2 reUpdate mod, would be quite cool tbh.
I did not understand anything but great video nontheless
i love pinsplash
yeah its the backwards long jump from mario 64

why not just set it at max speed if new speed is greater than max speed...

Oh Boy, time to listen to some Bismuth piano music and watch some Pinsplash.
According to this vid (hl2 devs reacting to speedrun), it seems that devs left this on purpose. kzread.info/dash/bejne/pX-TssawfJi_aMo.htmlsi=7tET1wB4wIgWfZVY
Sorry. This meth ache in my skull is hurting like hell.
AARRRRRRGGH *I FUCKING HATE MATH*
My fix if (flNewSpeed > flMaxSpeed) { if (mv->m_flForwardMove > 0.0f) { flSpeedAddition -= flNewSpeed - flMaxSpeed; } else if (mv->m_flForwardMove { flSpeedAddition *= -1.0f; flSpeedAddition += flNewSpeed - flMaxSpeed; } } else if (mv->m_flForwardMove { flSpeedAddition *= -1.0f; } Fixes this
