ACT_ definitions in the source code Created 9 months ago2023-08-01 17:38:37 UTC by Xenpanther420

does anyone know where the “ACT_” (parameters in a models QC file) is defined in the half life source code so I can understand how they function better?

You can do a file search for ACT_ in HL SDK.
Firstly in dlls/activity.h you have all the activity IDs defined: Further, elsewhere you will find given situations or events where animations are looked up by activity: So for example, when the grunt does a "victory dance" i.e. enemy is dead, it looks for an animation with the ACT_CROUCH activity. And then more of them later.

Thanks, now all I need help with is finding the specifics for the “ACT_” tags such as how many units (In hammer 3.4) of distance each Animation use

Well, that depends entirely on the animations themselves. You can inspect them in Blender and roughly see how far they go, I think.

I tried that with a really simple walk animation where the model pivots ~45 degrees around its feet (setting the pivot point to the 3D cursor which is placed near the bottom center of the feet).

however since I currently can’t compile the SDK to add custom NPC’s to my mod. I’ve had to rely on Monster_generic entities (in this case entity), with ai_scripted nodes to test movement animations, and other animations (besides the ACT_IDLE sequences).

The problem I’m having is my npc gets stuck (it shouldn’t be the terrain as the map is a barren cube) for some reason and I don’t know if it’s a ai navigation issue, an animation issue, or maybe even a distance issue (Hence why I want to find where the ACT_ scripts are located.

I'm not sure if it can actually move by itself, I'll have to take a look at the code tomorrow.
