Activating one Special Ability of several

[KarlM]

Hi

I'm trying to write a feat, which has several options. Depending on which option is chosen, I want a different Special Ability to show on the Specials tab.

So far, I can offer the choice with a custom expression in the feat based on a user tag denoting the set of possible abilities.

I can write an eval script in the feat to set another user tag on the hero denoting which special ability to activate.

I can see (using the hero tags floating info window) that the second tag gets set on the hero.

How do I either activate the relevant ability with a script in the feat or with a script in the ability?

I tried an eval script in the ability along the lines of

if (hero.tagis[User.Abil01] <> 0) then
  perform assign[Helper.ShowSpec]
endif

But I'm not sure what to do to get that script to run, or if - when it is run - it will do what I want.

Should I instead set ShowSpec on the tag from the feat? How do I do that?

Is in fact setting ShowSpec the right thing to do?

Help?

Thanks
Karl
