APawn::AIControllerClass

property Engine Blueprint Since 4.0
#include "GameFramework/Pawn.h"
Access: public Specifiers: UPROPERTYEditAnywhereBlueprintReadWrite

Description

The controller class to instantiate when this pawn is automatically possessed by AI. Set this to your custom AIController subclass in the pawn's constructor to give the NPC its own decision-making logic.

Caveats & Gotchas

  • • Setting this to a PlayerController subclass is technically valid C++ but will cause undefined behaviour — only AIController or its subclasses should be used here.
  • • Changing this property at runtime after the pawn is already possessed has no effect; the already-spawned controller continues to run. Call SpawnDefaultController() after updating the class if you need a new controller mid-play.
