function/variable help please
|
in zmud I had a variable that would look like this:
| Code: |
Name:
can_heal
value:
%if( %ismember(asleep, @afflictions) or %ismember(unconscious, @afflictions) or %ismember(stunned, @afflictions) or %iskey( @flags, paused) or %ismember(astralform, @defenses), 0, 1)
|
I understand that you need to make that a function now, or maybe I misunderstand. As a variable I can't get it working and as a function I can't either.
using the same code in a function I tried
#if (@can_heal(1)) {blah}
but that seems to be wrong.
Anyone tell me how to use it properly? |

That is #varfunc now.

Or you can make it a proper function with the following.
| Code: |
| #FUNC {can_heal} {#RETURN %if( %ismember(asleep, @afflictions) or %ismember(unconscious, @afflictions) or %ismember(stunned, @afflictions) or %iskey( @flags, paused) or %ismember(astralform, @defenses), 0, 1) } |
The new #FUNCTION command in CMUD is very powerful. It is a proper function call and requires a value to returned via the #RETURN command. |

@Tech: For that sort of function, like the example you gave, do you recommend using #func over #varfunc?

#functions are compiled, #varfuncs aren't. Try to convert your varfuncs to real functions - as Tech's demonstrated, it's as simple as adding #return at the start.
But functions can do all sorts of things that varfuncs can't, as well, because they can run commnads just like aliases and triggers can. The above example could be written like this:
#function {can_heal} {#if (%ismember(asleep, @afflictions) or %ismember(unconscious, @afflictions) or %ismember(stunned, @afflictions) or %iskey( @flags, paused) or %ismember(astralform, @defenses)) {#return 0} {#return 1}} |

Actually I have managed to get my #varfuncs to show compiled code - you have to play around with setting them to various variable types and check each time to see if they will compile. Hmm, although if they don't show the compiled code, they don't actually work at all... Seems like #varfuncs may be bugged, since none of mine worked until I changed them from Autotype and something else until they showed the compiled code. It seems to be the act of changing them and not what type that is important. Because they will compile on Autotype sometimes. |

Seb is correct that #varfuncs *are* compiled when possible internally. The difference is that if the #varfunc can't be compiled, then it just returns whatever value is stored without trying to execute it.
