Skill Pre-requisite

This should be easier than I'm making it. I'm trying to create a special ability that requires proficiency (or expertise) in a skill (in this case, Stealth). What do I put in the pre-requisites script to check for that?

You're looking for hero.tagis[ProfSkill.skStealth] <> 0. You may have to also look for hero.tagis[ProfDouble.skStealth] <> 0. I feel like I've seen it before where the Hero only has one of those, so test for both. It's been a minute since I did a pre-req so I don't know off the top of my head how to plug that in. But if you can find something with a pre-existing pre-req, it'll give you some direction.

Thanks! That put me on the right path. It needed to go in Expr-reqs, not Pre-reqs. I'm not sure how to OR hero.tagis[ProfDouble.skStealth] <> 0, but at least this is forward progress.

Set a variable.
If tag 1 is present, add 1 to the variable.
If tag 2 is present, add 1 to the variable.
If the variable > 0, the overall test is valid.

So I put something like this in the eval script:

Code:

var SkillSt as number



if (hero.tagis[ProfSkill.skStealth] <> 0)

     then SkillSt += 1

endif



if (hero.tagis[ProfDouble.skStealth] <> 0)

     then SkillSt += 1

endif

And this in the Expr-reqs:

Code:

SkillSt > 0

No you can do all that in the Expr-req script. Variables don't carry from one script to another.

All of that won't fit in Expr-req though...?

Correction: Do it in eval rules. Treat it like a regular script, but at the end, you're targeting "@valid = 1"

So:

if (SkillSt > 0) then
@valid = 1
endif

In eval rules, the error is "Invalid use of reserved word 'if' in script."

The full thing in the eval rule should be something like this:

Code:



    <evalrule phase="Final" priority="100000" message="You must be proficient in Stealth."><![CDATA[

 var SkillSt as number



SkillSt = 0



if (hero.tagis[ProfSkill.skStealth] <> 0)

     then SkillSt += 1

endif



if (hero.tagis[ProfDouble.skStealth] <> 0)

     then SkillSt += 1

endif



   if (SkillSt > 0) then

   @valid = 1

 

if (@valid = 0) then

         @message = "You must be proficient in Stealth."

       endif

]]></evalrule>
