Functions

BattleFx_RunGrowth

void BattleFx_RunGrowth(struct BattleEffectArgument *effect)

Grows vines from the ground, scattering dust from each root.

Abilities: Growth, Mad Growth, Wild Growth (kind 4).

Used by gBattleFx_EffectHandlers.

Line 36

BattleFx_RunPunji

void BattleFx_RunPunji(struct BattleEffectArgument *effect)

Grows green pillars from the ground, scattering dust from each root.

Abilities: Punji, Punji Trap, Punji Strike (kind 56).

Used by gBattleFx_EffectHandlers.

Line 42

BattleFx_RunGrowingColumns

void BattleFx_RunGrowingColumns(struct BattleEffectArgument *effect, s32 mode)

Vines (mode 0) or green pillars (mode 1) grow one every 4 frames, alternately mirrored, each throwing up dust from its root.

Column i appears on frame 4i + 9, shaking the screen, and grows 8 pixels a frame to a random length capped by its shape (i % 3); a pillar also stops at its gGrowth_PillarHeights. On frame 4i + 12 the targets react (even columns with a sound), and on frames 4i + 12 and 4i + 16 the column throws up a puff of dust. The battle moves on to the results 64 frames before the end; the scene fades out over 16 frames, and nothing grows in its last 4.

Called by BattleFx_RunGrowth (mode 0) and BattleFx_RunPunji (mode 1). work->particles holds the 16 columns (struct DualColumn) and PARTICLES the dust. Writes REG_BG2PA, REG_BLDCNT, REG_BLDALPHA and, on side 1, REG_BG2X; sets work->shakeFrames as each column appears. Ends with the transfer callback removed, the blitters freed and the canvas layer closed.

effect: the targets; variant picks the number of columns
        (gGrowth_ColumnCounts).

Used by BattleFx_RunGrowth, BattleFx_RunPunji.

Line 63

BattleFx_RunVine

void BattleFx_RunVine(struct BattleEffectArgument *effect)

Rising vines: sixteen green vines grow from the middle of the row of targets, 2 frames apart, and shrink back.

Abilities: Vine (kind 202).

Vine i appears on frame 2i + 5 and grows 4 pixels a frame up to 32, cycling through five 32x32 pictures, then shrinks away from frame 2i + 32; odd vines are mirrored. Vine i shakes the screen on frame 4i + 5. On frame 32 the targets react together, with a sound.

A Djinni appears first (BattleFx_RunDjinniEntrance). work->particles holds the 16 vines' x. Writes REG_BG2PA, REG_BLDCNT and REG_BG2X, sets work->shakeFrames, and ends with the transfer callback removed, the blitters freed and the canvas layer closed.

Used by gBattleFx_EffectHandlers.

Line 326

BattleFx_RunThorn

void BattleFx_RunThorn(struct BattleEffectArgument *effect)

Rising thorns: thorns burst from the ground one every 8 frames, throwing up dust from their roots.

Abilities: Thorn, Briar, Nettle (kind 5).

Thorn i appears on frame 8i + 9, shaking the screen, and throws up a puff of dust on each of its first two frames; on frame 8i + 12 the targets react with a sound. The battle moves on to the results 64 frames before the end, and the scene fades out over its last 16 frames.

effect: the targets; variant picks the number of thorns
        (gGrowth_Counts). gGrowth_Kinds gives each
        thorn's size and direction.

PARTICLES holds the dust, 64 puffs. Writes REG_BG2PA, REG_BLDCNT, REG_BLDALPHA and, on side 1, REG_BG2X; sets work->shakeFrames as each thorn appears. Ends with the transfer callback removed, the blitters freed and the canvas layer closed.

Structures

DualColumn

struct DualColumn

One growing column, laid over a struct EffectStep in work->particles.

Field	Declared as
`x`	`s32 x`	the root, in canvas pixels
`y`	`s32 y`	the root's row: 108 to 115, lower for later columns
`z`	`s32 z`	the EffectStep's z and velocityX, unused here
`velocityX`	`s32 velocityX`
`height`	`s32 height`	the full length, 55 to 118 capped by its shape
`velocityZ`	`s32 velocityZ`	the EffectStep's, unused here
`start`	`s32 start`	The frame it starts to grow; set, but the frame loop computes its own.
