companion

companion makes a stalker follow and assist the actor. The current implementation uses a simple walking behavior and planner action rather than a large LTX parameter set.

Parameters

companion has no scheme-specific LTX fields.

The section supports common switch fields. They are parsed into state.logic.

Runtime behavior

On activation, the scheme sets behavior = 0, which corresponds to the simple walk behavior in ActionCompanionActivity.

The scheme adds EActionId.COMPANION_ACTIVITY to the state planner. It is a stalker scheme, so it expects a stalker object with a planner and normal movement access.

The action runs when the NPC is alive, has no enemy, and the companion section is active. It:

• clears desired position and direction;
• enables talk;
• picks an accessible assist point near the actor;
• moves to that point using level path movement;
• chooses raid, rush, or assault state based on distance;
• switches to threat while standing near the assist point and looking at the actor.

Example

[logic]
active = companion@follow

[companion@follow]
on_info = {+companion_stop} walker@wait

Notes

• The source defines additional behavior constants for near/ignore/wait modes, but the current activation code always sets simple walking behavior.
• The assist position is chosen to the side of the actor and must be accessible to the NPC.
• Combat or death interrupts the action because the evaluator requires the NPC to be alive and without an enemy.
• Use common switch fields on the companion section to exit follow behavior when quest state changes.
