Unit Id, Item Id (well, any Id, actually)

06-22-2005, 05:30 PM

The search function is giving me a hard time now that the site is being worked on, so I guess I'll just post my question. What I am trying to do is figure out the Id of a unit type or an item type. I know the hard way of doing it, by preplacing the unit and then checking it's unit type Id, but surely there's an easier way? A way to see the Id in the object editor (display as raw data doesn't help it just shows the 4 letter codes).

If there's no way to see this number, then I guess I can get it from the 4 letter code? The function UnitId() seems to do that, it takes a string and returns an integer, but I'm still not sure if the string is meant to be the 4 letter code... and I can't find a similar function for items...

Vexorian	The four letters code is the id As in Typing 'Aloc' is another way of typing a number Groups of 4 ascii cars between ' ' are considered integers by JASS and the resulting integer is the number you would get if you read those 4 characters as a 4 bytes number.

Thanks Vex. another totaly unrelated question, but I just don't want to make a new thread...

Code:

    local group ug
    set ug = GetUnitsInRectMatching(GetPlayableMapRect(), Condition( function IsUnitType(GetFilterUnit(), UNIT_TYPE_HERO) ))

The editor gives me an error on the second line, saying: expected '
I tried my best to logically construct this line based on what the trigger editor throws out when I tell it to convert a GUI trigger to custom text. Is it that functions I call as a condition aren't allowed to accept arguments or something else lame like that?

The interface of the Condition function needs to be exactly "takes nothing returns boolean", so in your case do it this way:

Code:

function MyCondition takes nothing returns boolean
  return IsUnitType(GetFilterUnit(), UNIT_TYPE_HERO)
endfunction

....
set ug = GetUnitsInRectMatching(GetPlayableMapRect(), Condition(function MyCondition))

but, how do you do if you need to use a local in the main function and then check the local in the Condition(...) ?

yes, or teporarily copy the local to a global variable and in the Condition-function assign the global to a local again.

Ceo	Or use an if/then/else rather than a condition.

You can't use an if/then/else as a filter.

I know, I was just saying in many cases were you might use a condition an if/then/else would be easier. This just does not happen to be one of those cases.
