Launches up to max sparks from (px, py), 16.16, into the free slots (variant 0) of THOR_PARTICLES, walking them with spark and counting with index.

Each flies at angle at a random speed of 32 to 1054 (128ths of a pixel a frame) and lives 32 to 39 frames. Used for the pillar's 512 sparks and each bolt's 16; the mote's sparks are launched inline.

Function Documentation

◆ BattleFx_RunThor()

void BattleFx_RunThor ( struct BattleEffectArgument * effect)

The scene plays in two parts on the effect canvas.

Abilities: Thor (scene kind 12).

In the dusk part (THOR_DUSK_FRAMES, which A or B cuts short) a circle of 128 dots and three lines across it form over scrolling dusk clouds; the circle turns, sinks into the sky and a beam of light falls from it. In the lightning part (THOR_LIGHTNING_FRAMES) a pillar of lightning strikes the formation and throws sparks, THOR_BOLTS violet bolts follow while a violet mote sways above, and the formation is pushed back in smoke until an impact burst ends the effect. The sparks live in THOR_PARTICLES; a spark whose variant is 0 is free, and a positive variant counts the frames it has left.
