Remade T. Samson's "sword". Sorry, if it's a little spammy

Tainted samson looks great and I'm going to put you in mod credits for sure, I'll update the mod to put that over my sprite, but I'm not comfy putting xtrike's designs in the main mod, so I'll include them in an extras folder so anyone can replace them if they want.

Code for custom poofs. Haven't tried T. Andromeda, but tests on Lost and J&E showed that everything works fine.
Poofs just DON'T HAVE Parent nor Spawner nor even SpawnerType - it's all nil (or 0 for SpawnerType).
So I made it find first player with sword and just assume it was him.
If there is multiple players with swords or both J&E have one it wil stick to first one having (Jacob in second case). But I can't do anything better than that.
(edit: leave default poof if no players have sword)


function SpiritSwords:PoofReplace(poof)
if poof.SubType ~= 22 then return end
local data = poof:GetData()
if data.UpdatedCustomPoof then return end
local sprite = poof:GetSprite()
local pNum = 0
while Isaac.GetPlayer(pNum) and pNum<4
and not Isaac.GetPlayer(pNum):HasCollectible(CollectibleType.COLLECTIBLE_SPIRIT_SWORD) do
pNum=pNum+1
end
if pNum == 4 then
data.UpdatedCustomPoof = -1
return
end

local player = Isaac.GetPlayer(pNum)

local pType = player:GetPlayerType()

if ModdedSwordSprites[pType] == nil and pType >40 then
print("Incompatible player type: "..player:ToPlayer():GetPlayerType()) return end

if pType <41 then
sprite:Load("gfx/effects/"..VanillaSwordSprites[pType+1].."_sword_poof.anm2", false)
else
sprite:Load("gfx/effects/"..ModdedSwordSprites[pType].."_sword_poof.anm2", false)
end
if ModdedSwordSprites[pType] == "andromedab" then
local color = player:ToPlayer():GetHeadColor() +2
local tearVariant = player:ToPlayer():GetTearHitParams(WeaponType.WEAPON_TEARS, 1, 1, nil).TearVariant
if tearVariant == TearVariant.BLOOD
or tearVariant == TearVariant.CUPID_BLOOD
or tearVariant == TearVariant.PUPULA_BLOOD
or tearVariant == TearVariant.GODS_FLESH_BLOOD
or tearVariant == TearVariant.NAIL_BLOOD
or tearVariant == TearVariant.GLAUCOMA_BLOOD
or tearVariant == TearVariant.EYE_BLOOD
or tearVariant == TearVariant.KEY_BLOOD then
sprite.Color = Color(1, 0, 0, 1, 0, 0, 0)
else
sprite.Color = HeadColors[color]
end
end
sprite:Play("Idle", true)
sprite:LoadGraphics()
data.UpdatedCustomPoof = pType
end

SpiritSwords:AddCallback(ModCallbacks.MC_POST_EFFECT_INIT,SpiritSwords.PoofReplace,EffectVariant.TEAR_POOF_A)

Very nice, thank you! I've already begun sprite work on the poofs as well.
