Race PreReq

[Angela2013]

I was putting some flaws in and one of them had a prerequiste by being either a half-elf or a half-orc. I thought I had seen somewhere on how to do this under Expr-reqs like this:

#hasrace[rHalfElf] | #hasrace[rHalfOrc] <> 0

but it is not working. Any ideas?

Use the + sign instead of |

#hasrace[rHalfElf] + #hasrace[rHalfOrc] <> 0

EDIT: last line removed to reduce confusion due to my being factually incorrect

The | is an "or", so you were telling it "if either of these is invalid, give an error". Since you can't have two races, you are guaranteed an error

Um actually you can't use "|" in an IF statement in HL. That only works when doing searches or loops.

By putting the + you are adding together the return value of both macros and saying if either one is true then then whole thing is true. In essence saying if either a Half-Orc OR Half-Elf.

In example:
Race is a Half-Orc you get an answer back of "0 + 1 <> 0" which is true.
Race is a Half-Elf you get an answer back of "1 + 0 <> 0" which is also true.
Race is a Dwarf you get an answer back of "0 + 0 <> 0" which is false.

If you wanted to do this as a AND statement instead of OR you would have to use a Pre-req script like so. In this case saying you are both a dwarf and elf. Yea I know it can't actually happen its just an example.

@valid = 0
~ Check if we are a elf
If (#hasrace[rElf] <> 0) Then
   ~ Check if we are also a dwarf
   if (#hasrace[rDwarf] <> 0) Then
      @valid = 1
   Endif
Endif

I'd never tried it so I wasn't sure. prob shoulda stuck with just the first line but then I just had to keep talking and try to sound smart...

ShadowChemosh - you can use |:

if (hero.tagexpr[HasRace.rElf | HasRace.rDwarf] <> 0) then

will get you the same effect as

if (#hasrace[rHalfElf] + #hasrace[rHalfOrc] <> 0) then

You could also use

if (hero.tagexpr[HasRace.rElf & HasRace.rDwarf] <> 0) then

ShadowChemosh - you can use |:

if (hero.tagexpr[HasRace.rElf | HasRace.rDwarf] <> 0) then

To be clear yes it works with a Tag Expression but not when doing:

#hasrace[rHalfElf] | #hasrace[rHalfOrc] <> 0

correct?

I was trying to give a way of doing OR using #hasrace[] instead of showing a totally different method.

Correct - #hasrace[XXXXX] is hero.tagis[Race.XXXXX], so by replacing tagis with tagexpr, you get the option to construct an expression that you can test for, instead of testing for the simple presence of a tag.

(Ignore the HasRace tags in my earlier post - I should have typed Race).
