That page mostly talks about scripting because the character controller will automatically damage any object that has the health component on it. From the demo scene the red boxes have the health component attached so you can use that as an example and it really is just attaching the component so it's not enough to do a video on.
Sure, maybe that
single aspect of it isn't enough to do a video on, but do you really feel like the robust feature set you have around managing character health and other attributes isn't more deserving of a visual demonstration?
I finally figured out part of what my issue was and the issue was that I just couldn't tell when something was working and when it wasn't. I setup the character through the character manager, which seemed to work better than just trying to attach the scripts on my own. To test if the character was taking damage, I setup an audio clip to play on damage. That audio clip never played. When the object was hit, there was no indicator in the console. The only way I was able to finally notice that the object was taking damage was when I happened to be hovering over the health values in the Inspector while shooting at the object in play mode.
If I toggle "Deactivate on Death", that works just fine. Why does that work and not the audio clips? I have no idea at all, and the only way I'll get any clue about it is to jump back and forth between the demo scene, the documentation, these forums, and the discord channel.
I think most people on here are okay with trying to figure things out to some extent, but gosh. A 30 minute from you guys running through setting up this asset in some basic projects would go an insanely long way in making this asset more accessible.
You're an incredibly nice guy and I'm always amazed at how much patience you show when helping people, but man. I really wish we had more materials to learn from so that we could reference those more instead of desperately waiting for you to swing by in the forums or on the discord and save the day.
