[Chaos]

hey, i'm trying to get texture name when i shot to target texture but it doesn't work

function onShot(weapon, ammo, ammoInClip, hitX, hitY, hitZ, hitElement) 
usageInfoList = engineGetVisibleTextureNames () 
for key, textureName in ipairs(usageInfoList) do 
textureName = hitElement 
outputChatBox(textureName) 
end 
end 
addEventHandler("onClientPlayerWeaponFire", root, onShot)
