void LinkLuaModifier(string modifier_name, string file_path, int motion_controller_type)

Link a lua-defined modifier with the associated class. If the modifier is located within the root vscript folder, then the second argument (file_path) may be omitted链接一个已经用lua脚本定义的Modifier(类class)。如果这个Modifier脚本在根目录，第二个参数（文件路径）可以省略' 例：我们现在要创造一个Buff，名字叫modifier_evo_buff用来直接给单位加一个Buff，那么我们新建立了一个modifier_evo_buff.lua文件放在hero文件夹下，文件内容

--类名，跟文件名一致
modifier_evo_buff = class({})
--when a modifier created当Modifier被创建时
function modifier_evo_buff:OnCreated(table)
    --注意：这些函数是会被服务器和客户端同时执行，所以请判断（一般关键操作在服务器上，提示内容才在客户端上！）
    if not IsServer() then
        return
    end
   --set interval of think 设置计时器间隔
   self:StartIntervalThink( 1 )
end
--think callback 计时器回调函数
function modifier_evo_buff:OnIntervalThink(  ) 
    if not IsServer() then
        return
    end
    print("modifier_evo_buff:OnIntervalThink")
end
--return modifier's texture name返回该Buff图标资源名（这里用亚巴顿的第一个技能图标）
function modifier_evo_buff:GetTexture(  )
    return "abaddon_death_coil" 
end
--return modifier's effect name 该Buff携带的效果
function modifier_evo_buff:GetEffectName()
    return "particles/generic_gameplay/generic_stunned.vpcf"
end
--effect attached position 该Buff效果依附的位置
function modifier_evo_buff:GetEffectAttachType()
    return PATTACH_OVERHEAD_FOLLOW
end

--the others ,see API:CDOTA_Modifier_Lua 其他的复写函数请参考 API:CDOTA_Modifier_Lua

接下来在调用之前，声明链接（加载）这个Modifier

--参数1 Modifier名称（在本地化资源文本里，引动的就是这个，添加Modifier用的也是这个）
--参数2 Modifier的lua文件所在的位置
--参数3 Modifier控制类型
LinkLuaModifier("modifier_evo_buff","hero/modifier_evo_buff", LUA_MODIFIER_MOTION_NONE)
--If the modifier is located within the root vscript folder
-- call LinkLuaModifier("modifier_evo_buff", LUA_MODIFIER_MOTION_NONE)

声明完就可以为单位添加一个这个Modifier了

--entity为单位句柄
--技能为空
--Modifier名称（上面注册的那个）
--其他参数列表（这里添加了一个永久持续的Modifier）
entity:AddNewModifier(entity, nil, "modifier_evo_buff", { duration = -1})

English (google translation from chiness)

void LinkLuaModifier(string modifier_name, string file_path, int motion_controller_type)

Link a lua-defined modifier with the associated class. If the modifier is located within the root vscript folder, Modifier then the second argument (file_path) may be omitted a link with lua script has been defined (class class). If Modifier script in the root directory, and the second parameter (file path) may be omitted 'Example: We are now going to create a Buff, called modifier_evo_buff used to direct units plus a Buff, we established a new file modifier_evo_buff.lua on the hero folder, file contents'

--The class name, the file name is consistent with
modifier_evo_buff = class ({})
--when a modifier created when the Modifier is created
function modifier_evo_buff:OnCreated (table)
    --NOTE:These functions will be performed while the server and client, so please judge (usually a key operation on the server, only the prompts on the client!)
    if not IsServer () then
        return
    end
   --set interval of think sets the timer interval
   self:StartIntervalThink (1)
end
--think callback timer callback function
function modifier_evo_buff:OnIntervalThink ()
    if not IsServer () then
        return
    end
    print ( "modifier_evo_buff:OnIntervalThink")
end
--return modifier's texture name returns the Buff icon resource name (here with Abaddon first skill icon)
function modifier_evo_buff:GetTexture ()
    return "abaddon_death_coil"
end
--return modifier's effect name carries the Buff effect
function modifier_evo_buff:GetEffectName ()
    return "particles / generic_gameplay / generic_stunned.vpcf"
end
--effect attached position the Buff effect attachment position
function modifier_evo_buff:GetEffectAttachType ()
    return PATTACH_OVERHEAD_FOLLOW
end
 
--the others, see API:CDOTA_Modifier_Lua other replication functions refer to the API: CDOTA_Modifier_Lua

Before calling the next, the statement links (load) this Modifier

--1 Modifier parameter name (in the localized resource texts, to move is this, this is also used to add Modifier)
--Location parameter 2 Modifier of lua files are located
--Type of control parameters 3 Modifier
LinkLuaModifier ( "modifier_evo_buff", "hero / modifier_evo_buff", LUA_MODIFIER_MOTION_NONE)
--If The modifier is located within the root vscript folder
-- Call LinkLuaModifier ( "modifier_evo_buff", LUA_MODIFIER_MOTION_NONE)

End statement that can add a unit of the Modifier

--entity units handle
--Skills is empty
--Modifier Name (registered above that)
--Other parameter list (here we add a permanent ongoing Modifier)
entity:AddNewModifier (entity, nil, "modifier_evo_buff", {duration = -1})
