Interface.c controls the signs and such, I want to know if there is another thing I can calculate other than pressure or temperature.
What I mean is that I want to put something like {p} in a sign, but not have it register the pressure. What else is there?

Well is there? I might be able to make it display what element is on it, but Idk what you'd have to put. When I get off mobile I'll give you the snippet of code that controls it.
Edit: Here it is:
if(strcmp(signs[i].text, "{p}")==0)
*w = textwidth("Pressure: -000.00");

if(strcmp(signs[i].text, "{t}")==0)
*w = textwidth("Temp: 0000.00");

//Ususal width
if(strcmp(signs[i].text, "{p}") && strcmp(signs[i].text, "{t}"))
*w = textwidth(signs[i].text) + 5;
*h = 14;
*x0 = (signs[i].ju == 2) ? signs[i].x - *w :
(signs[i].ju == 1) ? signs[i].x - *w/2 : signs[i].x;
*y0 = (signs[i].y > 18) ? signs[i].y - 18 : signs[i].y + 4;
}
What else is there?

Besides the necro, it may have moved and/or changed coding. Not sure how to do it now until I find the signs again.
But even before that I need to fix a linker error, which pops up no matter where the files are.

Goodie cuz I nwasn't about to look through 4000 lines of code to find them. X|
