Unity ToLua 之 Lua调用C#(一)

Unity ToLua 之 Lua调用C#(一)

一.ToLua调用C#的类

• 在ToLua中调用C#与XLua相比，ToLua不需要写CS，其余语法格式大致相同
• 使用的类需要在CustomSettings中的customTypeList列表中进行填写，然后重新生成代码
  

public class LuaCallCSharp : MonoBehaviour
{
    
}

public class Test
{
    public void Speek(string str)
    {
        Debug.Log(str);
    }
}

GameObject = UnityEngine.GameObject
local obj = GameObject("zzs")

print(GameObject.Find("zzs").name);

print(obj.transform.position.x)

Vector3 = UnityEngine.Vector3
obj.transform:Translate(Vector3(1,1,1))
obj:AddComponent(typeof(LuaCallCSharp))

local test = Test()
test:Speek("zzs")

二.ToLua调用C#枚举

• 规则与Xlua相同，和上面的类一样，都需要添加到CustomSetting中的列表中，重新生成

public enum State
{
    Idle,
    Run,
    Atk
}

PrimitiveType = UnityEngine.PrimitiveType
GameObject = UnityEngine.GameObject
GameObject.CreatePrimitive(PrimitiveType.Capsule)

local a = State.Idle
local b = State.Run
local c = State.Atk

print(a)
print(b)
print(c)

if a==b then
    print("相等")
else
    print("不相等")
end

--枚举转字符串
print(tostring(a))
--枚举转Int
print(a:ToInt())
print(b:ToInt())
--Int转枚举
print(tostring(State.IntToEnum(2)))

三.ToLua中调用C#中数组

• 与Xlua相比多了一种将数组转换成Table的方法

public class Test2
{
    public int[] arr = {1,2,3,4,6};
}

local test2 = Test2()
print(test2.arr.Length)
print(test2.arr[0])
--第一种遍历
for i = 0, test2.arr.Length - 1 do
    print(test2.arr[i])
end
print("--------------------")
--第二种遍历
local t = test2.arr:ToTable()
for i = 1, #t do
    print(t[i])
end

--创建数组
local arr = System.Array.CreateInstance(typeof(System.Int32),3)
print(arr.Length)
arr[0] = 10
arr[1] = 20
arr[2] = 30
for i = 0, arr.Length - 1 do
    print(arr[i])
end
