Token Action HUD Arkham Horror RPG

System module for Token Action HUD Core that adds a fast action HUD for the Arkham Horror RPG (FVTT) system.

This is an ALPHA build focused on usability and stability. For planned work and deferred ideas, see Future Features.

Requirements

• Foundry VTT: v13
• Arkham Horror RPG System: >= 13.0.35
• Token Action HUD Core: >= 2.0.0

Compatibility Mode v13.0.3

• Arkham < 13.0.37: legacy compatibility mode (existing dynamic-import routing).
• Arkham >= 13.0.37: API mode (routes through game.arkhamhorrorrpgfvtt.api).

API mode details:

• No legacy fallback if a required API method is missing in API mode.
• Missing methods fail closed (action is skipped and a warning is shown).
• Dicepool actions use system API methods instead of direct actor data writes.

Upgrade note:

• If you are on module v13.0.2 and upgrade Arkham to >= 13.0.37, dicepool increment/decrement actions will not update correctly due to a system API breaking change.
• Upgrade this module to v13.0.3 (or newer) when upgrading the base Arkham system.

What is available in ALPHA (current tabs)

• Dicepool: DP +/-, Damage/Horror +/-, Refresh, Discard Die, Discard All Dice, Strain, Injury/Trauma
• Simple: Spend Regular Die / Spend Horror Die (API mode)
• Complex: Skill rolls (opens the system dice roll dialog)
• Reaction: Reaction-mode skill rolls (opens the system roll dialog)
• Insight: Spend / Refresh (opens the system roll dialog)
• Weapons: Lists owned weapons by order on the actor sheet and rolls them via the system dialog
• Spells: Lists owned spells by order on the actor sheet and rolls them via the system dialog
