我想覆盖一个函数来检查它的参数值,但是调用它并正常传递原始参数。这可能吗?我正在使用Corona SDK www.coronalabs.com
目前我的代码不起作用,是:
-- getting a refrence to the original function so i can replace it with my overriding function
local newcircle = display.newCircle
-- my override
display.newCircle = function(...)
-- attempt to pass the parameters to this function on to the real function
local t = {...}
newcircle(unpack(t))
end
-- calling the overridden function as if it were normal
display.newCircle( display.newGroup(), "image.png" )
答案 0 :(得分:0)
在新的display.newCircle
实现中,您使用的是未定义的t
表和不推荐使用的arg
自动表。
试试这个:
-- my override
display.newCircle = function(...)
local t = {...} -- you need to collect arguments to a table
-- dumb use of override
print(t[1])
-- attempt to pass the parameters to this function on to the real function
newcircle(unpack(t))
end
