To pause game engine resolution for interactive effects, you implement a continuation pattern that stashes sub-abilities into a waiting state. The engine pauses execution until the player provides the required modal decision or selection, then resumes the resolution chain automatically.

The continuation pattern handles target propagation by stashing sub-abilities when a waiting state triggers and propagating parent targets to the continuation. This maintains correct target references across the paused execution chain when the engine resumes after player input.

Yes, interactive effects support modal decisions across single-player, AI, and multiplayer sessions. The system routes UI modals for human players, processes AI legal actions automatically, and coordinates multiplayer routing to ensure all session types resume correctly.

The best way to manage engine state when resuming sub-abilities is updating the WaitingFor state variant and wiring the engine to stash and resume continuations. This ensures the engine correctly propagates targets and continues the resolution chain after the player action.

Game engines drop parent targets when resuming interactive effects if target propagation to continuations is missing. The engine must explicitly stash sub-abilities and propagate parent targets to the continuation to maintain correct references throughout the waiting state and resolution chain.

Yes, you need to update WaitingFor state variants to coordinate player decisions during mid-resolution. The engine wiring uses these waiting state variants to track required player input, stash sub-abilities, and correctly propagate targets when resuming interactive effects.
