加里的mod lua代码错误不起作用(实体X，得到零)

Question

我试图修复一些Garry's Mod插件，这就是发生的事情。我试图修复它很长时间，但我不是 Lua 编码中最好的：/。这段代码有什么问题？我收到此错误：

[ERROR] addons/garrys_bombs_5_base_528449144/lua/entities/gb5_shockwave_sound_lowsh.lua:80: bad argument #1 to 'SetPhysicsAttacker' (Entity expected, got nil)
1. SetPhysicsAttacker - [C]:-1
2. unknown - addons/garrys_bombs_5_base_528449144/lua/entities/gb5_shockwave_sound_lowsh.lua:80

而且代码很长。我让每个文件都工作正常，但此文件不起作用

有人有可能为我解决这个问题吗？甚至只是告诉我出了什么问题？我会很高兴的。如果需要，我可以发送所有文件。井。。。这不是我的插件，但我正在尝试修复现有的插件。有人也试图修复它，但他没有(实际上他破坏了它(。

错误的含义

• 在ENT:Think()函数中，您正在调用ent:SetPhysicsAttacker(ply)
• ply未在该函数中的任何位置定义，因此 nil(Entity expected, got nil)

如何解决这个问题

如果没有玩家对此实体造成的损害负责，请删除行ent:SetPhysicsAttacker(ply)。

否则，在创建时，使用 SetOwner 将所有者分配给实体。
这将允许你在Think钩子中使用self：GetOwner((

例

hook.Add("PlayerSay", "SpawnEntity", function(ply, text)
if string.lower(text) == "!spawnentity" then
-- Create your entity
local myEntity = ents.Create("gb5_shockwave_sound_lowsh")
myEntity:SetPos(ply:GetPos())
myEntity:SetAngles(ply:GetAngles())
myEntity:Spawn()
-- Sets the owner to the player that typed the command
myEntity:SetOwner(ply)
return ""
end
end)

-- Inside your entity code
function ENT:Think()
print("My owner is: " .. tostring(self:GetOwner()))
-- ...
ent:SetPhysicsAttacker(self:GetOwner())
end
