Description

Motivation and context

Some Opposed Tests (namely, Group Advantage actions) should not generate advantage when winning them. And while system itself does not handle that in any way, I've added support for that in the new Token Action HUD WFRP4e update, as can be seen here (for example):

https://github.com/Foundry-Workshop/token-action-hud-wfrp4e/blob/1356baa3439c4b6b6f450399d9c288bd86efa2af/dist/modules/GroupAdvantage.js#L76-L84

I went ahead and added a new flag in Tests' options called preventAdvantage with the idea that if the attackerTest has that flag, then no advantage should be generated by that test by other automations.

Summary of changes

Added a check that checks for two things:

1. Is the Group Advantage enabled?
2. Does the attackerTest have option preventAdvantage set exactly to true?

If both are true, then advantage is not calculated for the Opposed Test.

How has this been tested?

1. Use Group Advantage actions like Batter, Trick or Additional Effort from the Token Action HUD WFRP4e v1.2.0

• should notice that they no longer grant advantage due to "won opposed test", but instead grant advantage based on actions themselves

3. Perform any Opposed Test outside of actions mentioned above

• should notice that automated advantage is handled as usual by GM Toolkit
