Custom npc not turning around when hitting a wall

[KoolGamer32]

I just finished making a custom boss npc and when it hits a wall it doesnt turn around and instead moonwalks like micheal jackson. This is probably a simple fix but Im pretty new to the whole custom npc thing.

Can I see the code? I might be able to help.

this is the code

Spoiler: show

local npcManager = require("npcManager");
local flyingSpiny = {}
local npcID = NPC_ID
npcManager.setNpcSettings({
id = npcID,
gfxoffsety = -2,
gfxwidth = 128,
gfxheight = 128,
width = 128,
height = 128,
frames = 2,
framespeed = 8,
framestyle = 1,
nogravity=0,
jumphurt=1,
spinjumpsafe = true,
spawnid = 381
})
npcManager.registerHarmTypes(npcID, {
HARM_TYPE_NPC,
HARM_TYPE_HELD,
HARM_TYPE_TAIL,
HARM_TYPE_SWORD,
HARM_TYPE_PROJECTILE_USED,
HARM_TYPE_LAVA
},
{
[HARM_TYPE_NPC]=204,
[HARM_TYPE_HELD]=204,
[HARM_TYPE_HELD]=204,
[HARM_TYPE_PROJECTILE_USED]=204,
[HARM_TYPE_LAVA]={id=13, xoffset=0.5, xoffsetBack = 0, yoffset=1, yoffsetBack = 1.5}
});

local waves = {{5,8}, {1,4}}

function flyingSpiny.onTickSpiny(v)
if Defines.levelFreeze then return end

local data = v.data._basegame

if v.isHidden or v:mem(0x12A, FIELD_WORD) <= 0 or v:mem(0x124, FIELD_WORD) == 0 then
data.spinyTimer = 0
data.spinyPhase = 0
data.spinyBall = 0
data.spinySine = 0
return
end

if v:mem(0x138, FIELD_WORD) > 0 or v:mem(0x12C, FIELD_WORD) > 0 or v:mem(0x136, FIELD_BOOL) then
data.spinyTimer = 0
data.spinyPhase = 0
data.spinyBall = 0
data.spinySine = 0
return
end

local data = v.data._basegame
if data.spinyPhase == nil then
data.spinyTimer = 0
data.spinyPhase = 0
data.spinyBall = 0
data.spinySine = 0
end
v.speedX = v.direction * NPC.config[v.id].speed
data.spinySine = data.spinySine + 1
local cfg = NPC.config[v.id]

if data.spinyTimer > 75 then
data.spinyBall = 1
v.speedX = 0
end
if data.spinyTimer == 125 then
for i = waves[data.spinyPhase + 1][1], waves[data.spinyPhase + 1][2] do
local needles = NPC.spawn(cfg.spawnid,v.x + 0.5 * v.width, v.y + 0.5 * v.height,player.section, false, true)
needles.data._basegame = needles.data._basegame or {}
local needleData = needles.data._basegame
needleData.spinyBulletDirection = i
needles.friendly = v.friendly
needles.layerName = "Spawned NPCs"
end
data.spinyPhase = (data.spinyPhase + 1) % 2
end
if data.spinyTimer > 130 then
data.spinyBall = 0
data.spinyTimer = 0
v.speedX = 1
end
data.spinyTimer = data.spinyTimer + 1

v.animationTimer = 250
if cfg.framestyle == 1 then
v.animationFrame = math.floor(data.spinyTimer/cfg.framespeed)%cfg.frames + cfg.frames + (cfg.frames * v.direction)
elseif cfg.framestyle == 0 then
v.animationFrame = math.floor(data.spinyTimer/cfg.framespeed)%cfg.frames
end
if data.spinyBall == 1 then
v.animationFrame = v.animationFrame + 2
end
local inItem = v:mem(0x138, FIELD_WORD)
--something ain't right with vanilla here...
if inItem == 1 or inItem == 3 then v.animationFrame = v.animationFrame + 1
elseif inItem == 2 then v.animationFrame = v.animationFrame - 2 end
end

function flyingSpiny.onInitAPI()
npcManager.registerEvent(npcID, flyingSpiny, "onTickEndNPC", "onTickSpiny")
end
return flyingSpiny

the code is for a custom spiny boss that uses the ai of a flying spiny but instead of flying it walks around. The point is when it hits a wall it doesnt turn the sprite around it just moonwalks as i mentioned above in my previous reply
