Can you change value states in functions? I am asking becouse Im starting to see how much code I can kill by usung functions but I set up this function to pass some value states with nothing happing.So my question is can I? here is the function with real time states.

+ Code Snippet

function playmyobject(potionnum)
playobject=0
shootfire=0
through=0
nextshoot=0
dec potionnum
shoottimefire=0
endfunction

edit:

I made thease 2 functions here and they work great but only becouse they are commands and not states.

+ Code Snippet

function blinkeye(objnum, fnum ,fnum2)

 offset limb objnum,fnum,0,200,ffa#/5.0
 offset limb objnum,fnum,0,ffa#/5.0,ffa#*-1
 offset limb objnum,fnum2,0,200,ffa#/5.0
 offset limb objnum,fnum2,0,ffa#/5.0,ffa#*-1
endfunction


function blinkeye2(objnum, fnum ,fnum2)
 offset limb objnum,fnum,0,200,ffa#/5.0
 offset limb objnum,fnum,-4,ffa#/5.0,ffa#*-1
 offset limb objnum,fnum2,0,200,ffa#/5.0
 offset limb objnum,fnum2,-4,ffa#/5.0,ffa#*-1
endfunction

It looks like you are trying to set variables that exist outside of the function. You should declare those values you want to affect as global.

+ Code Snippet

global a = 0
b = 0

MyFunc()

print "a = "; a
print "b = "; b

wait key
end

function MyFunc()
   a = 123    ` Will affect 'a' outside of the function - it's a global
   b = 123    ` Won't affect 'b' outside of the function
endfunction
