Hi Mr. Occlusion,
Enjoyed your first tutorial!
SO... I tried to follow it best I could, and in the end, I didn't have a working door...
It's probably me

First, I see in the script where the sound file is indicated... and i found a sound file I liked too... but what was not covered was how to properly get the sound file INTO the asset manager (I think I managed this...)... but beyond that, how to get the sound into the scene...
I just put the wav file in a new sub directory in "sounds".
The error message is that the sound file does not exist.
It also had an interesting error: "Sound file bling.ogg does not exist". I never even tried to reference such a file, so that leaves me confused. Perhaps bling is some kind of default sound?
But I had other problems... The trigger never worked.
I know the physics is at least partially right (the gun "hits" the door). The "Door open trigger demo" message showed up in the console, so I know the script is running....
Here are some error messages in the console:
"LUA ERROR: entity.callFn(..) failed. missing arg2 Target ID is invalid"
LUA ERROR: Tag name [ HUD ] not found or it is invalid, have you used the correct tag name? Does the tagged object exist?
LUA ERROR: entity.callFn(..) failed. missing arg2 Target ID is invalid
I'm not able to understand this. I am suspecting that it is actually an error related to the use of the FPS kit. (who else would have a HUD? right?)
some other errors:
"failed to load the Particle universe resource:mp2_explosion_26.pu
failed to load the Particle universe resource:mp_bullettrail_05_large_b.pu"
I suspect this has to do with the weapon in the kit? I don't know what else might be using particles.
Anyway, I guess the REAL issue is now to debug SkyLine projects.
Thanks to you, and anyone else willing to help this noob
