OMG, thank you! I feel a little dumb because the answer was really simple, but it worked, and I'm happy that I can get that food collection/looting element to my game. Highly appreciated! I'll let y'all know if I encounter other difficulties. 

Looks pretty cool, reminds me of older classics gameplay-wise, but with newer artwork. I wishlisted it, I'll look more into it in the future.

Noob here, hopefully this question will be easy for more experienced people. Having trouble with specifically ForeverZeros Hunger HUD addon script, here
I can't figure up how to get the HUD to show up. I found this thread, here - the person said,
 

There should be a part that specifies which switch controls the HUD being displayed. I believe the default is switch 10. To turn on the HUD you simply need to create an event that turns on the switch. I actually use the script in several of my projects, and I accomplish this by simply running an autorun event on the first map I use, and tell it to turn it on, then erase the event.

My problem is, I don't know what to type in to control the defined switch within the event editor. The defined switch is part of a script, it isn't part of the regular switch system. I assume I have to type a command with the script function in the third tab, I'm just unsure of what that is. Below is the script.

The part I'm struggling with is this below,

 # Define switch for active/visibility control within game.
  ONOFF_SWITCH = 10
  

I understand what I'm supposed to do, (change that switch) so that it is visible within the game. Unsure of how, and I couldn't figure it out through a couple of hours of digging around. I do have both scripts, (Hunger/Thrist + The Hunger HUD addon, both from same thread), and I'm on XP. Just can't figure out how to change that defined switch. Sometimes I can see the HUD flash for a split second if I leave and exit the menu, (it works*, just doesn't stay, (presumingly because of the switch)) but I assume that's just XP jank.

Any help for a newbie would really make my week, been trying to figure this out on my own for a number of days. I've been lurking on the forums for the past couple of days, hope I got this on the right board. Love what y'all do on the website. Making dreams reality ~ Pce.
