Using a perk (game variable) as a value

[Bladestorm Games]

I'm trying to simplify some code for a custom Buff, where its Duration is increased based on a Perk's level, trying to use the Perk as a Value input, the following throws an error

<effect_group>
   <triggered_effect trigger="onSelfBuffStart" action="ModifyCVar" cvar=".buffEnragedDuration" operation="set" value="5"/>
   <triggered_effect trigger="onSelfBuffStart" action="ModifyCVar" cvar=".buffEnragedDuration" operation="add" value="#perkPummelPete"/>
</effect_group>

 

Note 1: Looking into the Documentation section of Buff.xml, I see this:

Quote

value (Float,@cvar,#gameVariable) : Leading with @/# will parse the value of an existing cvar or game variable instead of a number.

 

 

Note 2: I've tried adding   target="self"   to the triggered_effect line of code that uses   value="#perkPummelPete"   and still fails.

 

 

Note 3: The Error being thrown:

 

 

 

 

The currently working code, to be simplified:

  <triggered_effect trigger="onSelfBuffStart" action="ModifyCVar" cvar=".buffEnragedDuration" operation="set" value="5"/>

The cvar would still have to be set somewhere, if not in the buff as you already have, it could be done on the perk using kind of the same format you have. Or you could add it to the status check buffs, or buffPerkAbilityUpdate where TFP stores several already.

 

But a perk isn't a variable, so it won't work as you are trying. Honestly, if it works fine as you have it, I'd just leave it as is.

Thanks for the help, I went with the buffPerkAbilityUpdate "method", where I store some custom variables based on the level of perkPumelPete.

 

I'll provide my code for my custom buff, but some notes:

1) Buff name is Enraged.

2) If you have atleast 1 point into Pummel Pete, your Power Attacks will grant the buff (renew/stack if you already have the buff).

3) Buff grants 10% Attack Speed, and 10% Movement Speed per Stack of Enraged.

4) The Buff displays a UI for the Duration, and another UI for the Effect/Value granted by the buff
