i love these videos

3:05 Great comedic timing

just one more half-life 2 playthrough before bed

Awesome video! I once made my own navigation system for my game when I was using a custom fork of the Q2RTX engine, without looking at any references or other solutions except for the actual pathfinding algorithm (Breadth-First Search), and I'm quite surprised how close parts of my solution was to some of the stuff you explained in this video. Now I just moved to UE5 lol.

the half life version of shounic. i love this guy. He has answers to questions i never asked, but very much needed to know. ill probably never use this information, but ill be damned if i dont find it incredibly interesting.

10:34 sliiide to the left, sliiide to the right!

6:57

wow, just wow

when he talked about the xbox 360 cheat codes, and said that in theory they would work, was i the only one to notice that the code is commented out? it won't work if it's commented out that's for sure

i fully expected the last guy to make an entirely new page about displacements just so he could make that edit

Half Life 2 if the gunplay was good:

Hi @pinsplash, is this mod working also for the latest Half-Life 2 - 20th Anniversary Celebration update? Thanks

This reminds me of the "desktop mode" mod on Half Life Alyx. Where they got everything working with a mouse and keyboard. Only problem? You can REALLY feel the game was not meant to be played like that, like how this shows.

very nice, cheers :)

So if there’s lighting issues with displacements, would having your perpendicular wall overlap even a bit with the other wall be a fix, or am I talking out of my ass?

Decinc?😮

I too like large sized holes

first video was understandable with some minor confusion, watching this one made my head hurt

Trae pistola no chiste muerto pistola

Needed something to watch on our date tonight, thank you Pinsplash

16:10 see if you can find it in code that StudioMDL uses when handling `walkframe`

YES NODEGRAPHS I ACTUALLY UNIRONICALLY REQUIRE THIS INFORMATION! YEEEAAAAAHHHH

this inspired me to node my map

4:10 you could say theyre... comparing nodes

Many thanks- and Merry Christmas!

Now I want to know how different Source 2 is

7:08 this is possibly one of the biggest half life lore drops I've ever witnessed, the only bigger mystery is who's G-man LOL

This is vital information to beginner source modders

Node Graph out of Date. Rebuilding...

Nav_edit 1 My favorete command (especially in tf2, rly helpful)

Thanks for making these videos. It's really interesting learning how it Source handles navigation. Makes me wonder what changes Source 2 navigation has. Also, if by chance you make more nav videos, I'd love to know how flying NPCs navigate. Especially the man hacks because they seem to use the Z axis really well, swooping up and down.

Atleast this looks better than my runs. Usually I or others get kicked or leave (not me leaving) if they get hit ONCE, lol. There's a reason I stopped playing L4D2 versus

Perfect! Another video discussing a really old game engine!

Node Graph out of Date. Rebuilding...

In the new HL2 Commentary, a running problem that is brought up is the combined cost of displacements and navigation creating performance issues. What makes it prohibitive to have both at the same time?

Thank you, this is very informative :)

"Go on, Gordon. I won't Look 🥺😳😏"

Shounic's lost brother

new pinsplash video and it's also epic

thanks man this is actually a big help, the valve wiki does not mention alot of important info that you have to learn to properlly node your map, where did you get all this information anyway?

Is there a way to check the compile date that it’s checking to see if the node graph is updated? Or is it just the creation date on the file?

Are you meaning to tell me that Node Graph Rebuilding isn't just a stutter generation engine???

This video is out of date. Rebuilding.

lowering framerates, scripts, save-loading like mad.... Dislike all of it and i can see why the pompus oldschool people tried to stem things like that.

hello

This is a great video

I created a very similar system in my game and I've never seen how Valve did it before. that felt weird watching it. what I do differently is that each node has a height and a radius. When placed It automatically expands and tests to see how big of a radius and height it can get before it collides with the world. a node that's under a door frame for example cannot get too big. then each npc can only use that node to find a path only if it's smaller or equal to the node's height and radius. so it creates a graphmap for each npc you have in the map. a big enemy would have to find another path around the doorway to navigate. a small enemy could simply walk right to it.

Thanks for these deep dives. I love these things. Source engine is just full of quirks, showing how battle tested it must have been for the time.
