Prereq question

The Dwarf and Elf races assign tags to the hero when they're present.
The tags are Race.Elf and Race.Dwarf. To check for those tags in a
prereq, you'd do this:

if (tagis[Race.Elf] <> 0) then
@valid = 1
endif
if (tagis[Race.Dwarf] <> 0) then
@valid = 1
endif

The first 'if' statement checks for the elf tag - the second checks for
the dwarf tag. If either is present, the validity is set to 1.


A shorter (but perhaps less clear) version of the same thing would be:

@valid = tagis[Race.Elf] + tagis[Race.Dwarf]

This works because tagis returns 1 if a tag is found, and 0 otherwise.
So if the "Elf" tag is present, this translates into:

@valid = 1 + 0

or simply

@valid = 1


Hope this helps,
