我正在尝试改变我在 this video中找到的类示例,以使其更加流线型使用.希望我的评论可以解释我正在努力完成的事情.我遇到的问题是当我尝试使用数据表时它会给我这个错误:lua:clas
我假设这意味着数组没有正确传递给函数,但我不知道为什么.我是Lua的初学者.
这是我得到的:
local enemy = {}; --enemy class table
function enemy:New(data)
local object = {}; --table to store all of data within class
local len = # data --get length of passed table
for i = 1, len, 2 do --loop to input all data from passed table into object table
object.data[i] = data[i + 1];
end
function object:getData(choice) --function that allows us to retrieve data from the class
return self[choice];
end
return object; --return class data table so we can create objects using the class
end
local monsterdata = {"name", "monster", "x", 64, "y", 128, "hp", 4}; --table containing data of monster. keys are odd numbered, values to those keys are even numbered
local monster = enemy:New(monsterdata); --create a object using the class
local test = monster:getData("x"); --set variable to a value with the getData function
print(test);
如果你想让对象保存数据,你可能想写
object[data[i]] = data[i + 1];
代替
object.data[i] = data[i + 1];
这样打印的结果是64.
