How To Create a Crank Wheel and Shutter Door in Source 2 Hammer

Please leave a comment if you have any video ideas!
This tutorial involves the use of the prop_animinteractable entity to create a crank wheel that controls a func_movelinear and a prop_dynamic rolling shutter door.
This can be used to create all sorts of dynamic systems for the player to interact with.
Made using the Half Life Alyx Workshop Tools version of Hammer for Source 2

bless you for making these tutorials

[@romeogolf7761]

@Hosomi you are a real OG for posting these tutorials. Thanks.

[@willhart2188]

Very cool!

[@afriendlykoopatroopa5001]

I know that this seems quite simple, but I was wondering if you could teach how to activate the player's flashlight in a dark room. I cannot figure out how to use a trigger to activate it.

[@Hosomi]

I haven't looked into that yet, but thats a good idea!

[@doctorfaker391]

Are you thinking about making a tutorial about markers that are able to draw on surfaces?
Btw I’m not super into mapmaking but your videos are entertaining to watch!

[@DimensionalRun]

Here's an already-made tutorial on it if you're interested th-cam.com/video/h-uFYfYjQis/w-d-xo.html

[@doctorfaker391]

DimensionalRun Oh thanks!

[@Hosomi]

I haven't made a markers tutorial, as I've seen a few other tutorials for it around and it doesn't seem like a very important thing to cover

[@HUDcats]

Yes

[@Marcus_-bb9ho]

Great video! Could you make one on the green energy balls at the end of the campaign?

[@Hosomi]

Could do. They're pretty simple to do!

[@NationalSecessionistForces]

Very nice tutorials. Are you familiar with VScript by any chance? I'm a very experienced programmer, but the documentation is really lacking and I'm not sure what it can do in HL:A and what it cant. Looking at some of the weird example scripts it seems possible to create entire new entities just using Lua, but I see no documentation for this shit anywhere. Valve, give us a real SDK with C++ Codebase assess already.

[@Hosomi]

I'm not too familiar with VScript myself, but people are making progress with it. Afaik you can't create new entities with it at the moment, but I may be wrong
All I can say is, keep an eye on the VDC, and try asking around on the Source modding discord servers

[@Hosomi]

Just checked the VDC and found there's a new page listing a load of API calls
developer.valvesoftware.com/wiki/Half-Life_Alyx_Scripting_API

[@perify_]

Hey. Ik I'm a little late here but how do u make it retract if you haven't turned the crank fully?
Edit: NVM I'M AN IDIOT!

[@amber.mp4]

Could you make a video on how to make drawers? I can't find any videos on it

[@Hosomi]

Good idea. They're just a prefab. You can see how to load prefabs in my video on dynamic lights, but I'll make a video dedicated to them too

[@FoxGAMING-NTF]

Hi, could you do a video on how to use the point_value_remapper? I don't have Alyx, and I'm making something for SteamVR's Source 2, and this tutorial is essentially exactly what I want to do, have a wheel that turns in VR, which will open a door, however prop_animinteractable is unfortunately not in SteamVR's Source 2.

[@Hosomi]

I'm unfamiliar with the differences between HLA and SteamVR, but there is a tutorial on how to use point_value_remapper on the VDC you can refer to

[@FoxGAMING-NTF]

@@Hosomi Yeah, that's the only tutorial there is of it, and it doesn't work right for me.

[@Perenbarn]

@@FoxGAMING-NTF same here. how do I make an Animation Cycle move. Only axis works for me.

[@peluchefps]

Can you make water in source 2?... it would be groundbreaking to see a video about that, there isn't any video about fluids.

[@Hosomi]

There is no water in Half Life Alyx unfortunately

[@abstract_duck]

is there a way to make sliding door that you can drag open?

[@Hosomi]

That'd be simple to achieve, just a physics prop and a phys_slideconstraint should work :)

[@abstract_duck]

@@Hosomi yup ... works just fine ... thanks

[@Jess_Atomoxetine]

Please can you explain physics hinges next?

[@Hosomi]

They should be the same as in Source 1, but I could do a video on them still

[@elliotbusse452]

Do you/anyone reading this know about in Hammer view distance? In making a map a few weeks ago I've somehow changed my render distance in the 3d tools section to around a thousand units. I don't even know what I was doing when I did it. At some point I while hitting a few buttons my main viewing screen went black (unless looking at the sky) and so anything past 1k units is not drawn in.

[@Hosomi]

There should be an option for this if you go to Tools>Options>View 3D and reset Backplane distance to the default 25000

[@elliotbusse452]

@@Hosomi You are amazing, thank you so much!

[@fakeporpss3237]

how do you use a switch to open the door?

[@Hosomi]

I have a tutorial that covers switches
Just add an output to that switch that opens or unlocks a prop_door_rotating_physics

[@fakeporpss3237]

@@Hosomi i found out that with the switch you can just set the trigger to open and it will open the door

[@st1kcc333]

How did Half-Life make train crash animations?

[@Hosomi]

The train crash scene was probably just an animated prop

[@st1kcc333]

How do you make a button???
