FieldFx_UpdateScaledArcObjectACopy Anchor Link

void FieldFx_UpdateScaledArcObjectA(union FieldObject *fieldObject)

Per-frame update of arc A: over 32 frames it swells and shrinks again (scale sin(frame / 64 turn)) while it rises a pixel a frame on the object it follows, 9 pixels in front of it and up to 5 pixels further while small.

Used by BattleEffect_CleanupSceneObjects, BattleFx_SpawnScaledArcObjects.

Line 11

FieldFx_UpdateScaledArcObjectBCopy Anchor Link

void FieldFx_UpdateScaledArcObjectB(union FieldObject *fieldObject)

Per-frame update of arc B: arc A upside down, 16 pixels in front of the object and up to 5 pixels nearer while small.

Used by BattleEffect_CleanupSceneObjects, BattleFx_SpawnScaledArcObjects.

Line 36

BattleFx_SpawnScaledArcObjectsCopy Anchor Link

void BattleFx_SpawnScaledArcObjects(struct FieldActor *linked)

Spawns the two swelling arcs (object 26) on an object, A and B (B upside down); they follow it for 32 frames, then free themselves. They draw with the effect's spark tiles, so they need the effect's work; the casting hooks below spawn them every 16 frames, and BattleEffect_CleanupSceneObjects waits for the last to end (at most 30 frames).

Used by BattleFx_FlickerObjectAndTick, FieldFx_CycleObjectValueByCounter.

Line 95

BattleFx_FlickerObjectAndTickCopy Anchor Link

void BattleFx_FlickerObjectAndTick(union FieldObject *fieldObject)

Per-frame update: flashes an object between sprite param 7 and 0 every 2 frames and spawns the swelling arcs on it every 16. EventObject_Initialize gives it to the caster as a cast starts with a flash (scene->visible).

Used by EventObject_Initialize.

Line 142

FieldFx_CycleObjectValueByCounterCopy Anchor Link

void FieldFx_CycleObjectValueByCounter(union FieldObject *fieldObject)

Per-frame update: cycles an object through sprite params 0 to 5, one step every 2 frames, and spawns the swelling arcs on it every 16. EventObject_Initialize gives it to the caster in place of the flicker while flag 0x140 is set.

Used by EventObject_Initialize.

struct ArcSprite

A sprite (struct AnimationObject) as the arcs set it up: its image's three OAM attributes and its bookkeeping; the notes give the AnimationObject fields at the same offsets.
