-- Parity test: Self-Destruct/Explosion against a mid-Fly/Dig
|
|
-- (semi-invulnerable) target still faints the user (#528).
|
|
--
|
|
-- EffectRegistry.runDamaging's target.invulnerable branch prints the miss
|
|
-- text and returned without ever calling record.onMiss, while the
|
|
-- accuracy-roll, type-immunity and floored-damage miss branches all did.
|
|
-- EXPLODE_EFFECT (src/battle/MoveEffects.lua) relies on onMiss to run
|
|
-- battle:selfDestruct(user); skipping it left the user at full HP.
|
|
--
|
|
-- pokered engine/battle/core.asm MoveHitTest: "bit INVULNERABLE, [hl] /
|
|
-- jp nz, .moveMissed" sets the same wMoveMissed as a failed accuracy roll,
|
|
-- and the shared miss handler runs the explode effect regardless of which
|
|
-- branch set it ("even if Explosion or Selfdestruct missed, its effect
|
|
-- still needs to be activated"). JUMP_KICK_EFFECT's onMiss filters on
|
|
-- reason == "accuracy", so a crash-damage kick must NOT also fire here.
