https://doc.cdryx.net/CdryxAIOUPlugin/ccharumodule/animation/index.html Overview UCAnimInstance is the custom UAnimInstance subclass used by all characters. It provides a typed variable system for driving AnimBlueprint state, automatic computation of speed/direction/lean/slope, montage priority management, and integration with the combat state machines. CMontageNotifier defines the AnimNotify classes used for combat events. UCAnimInstance Name Description readAnimBoolVar / writeAnimBoolVar Read/write typed bool variables (falling, accelerating, sprinting, fighting, top-viewing, interrupted) readAnimFloatVar / writeAnimFloatVar Read/write typed float variables (speed, direction, slope angle, lean angle, roll, pitch, yaw) readAnimFNameVar / writeAnimFNameVar Read/write typed FName variables readAnimFVectorVar / writeAnimFVectorVar Read/write typed FVector variables readAnimFTransformVar / writeAnimFTransformVar Read/write typed FTransform variables cdryxAnimSequenceMap Named animation sequences from FCCharacterDetailMaker::animSequenceMap cdryxBlendSpaceMap Named blendspaces from FCCharacterDetailMaker::blendspaceMap setPriority Sets montage priority for the priority-based playback system comparePriority Compares two montage priorities (used by ICAnimePrioritizer) // Typed variable system — used in AnimBlueprint via BlueprintCallable getters: animInstance->writeAnimBoolVar(CAnimBoolVar::CDRYX_FIGHTING, true); bool fighting = animInstance->readAnimBoolVar(CAnimBoolVar::CDRYX_FIGHTING); float speed = animInstance->readAnimFloatVar(CAnimFloatVar::CDRYX_SPEED); float direction = animInstance->readAnimFloatVar(CAnimFloatVar::CDRYX_DIRECTION); // FName-based variants for custom variables (not in the enum): animInstance->writeAnimBoolVar_(FName("MY_CUSTOM_BOOL"), true); bool custom = animInstance->readAnimBoolVar_(FName("MY_CUSTOM_BOOL")); // Every write triggers moveOnAllSimpleStateMachine() to advance combat state machines.
