Redefining a function

[Zhuang Zhao <zhuazhao@...>]

Hi everyone,

I'm currently coding a modification for a game using lua, and I want to redefine a function. The function is called OnTick, and is called every second. Here's the original ,

function PowerStruggle:OnTick()
    System.LogAlways("++++++++++++OnTick++++++++++");
    if (self:GetState()~="PostGame") then
        self:UpdateReviveQueue();
    end
    
    TeamInstantAction.OnTick(self);
end

And here's my hook creation function,

function hookFunction()
    local oldTick = PowerStruggle.OnTick;
    LogAlways("oldfunc:"..tostring(PowerStruggle.OnTick));
    PowerStruggle._OnTick_ = function()
        LogAlways("*****************************OnTick Hooked!!!****************************");
        -
 oldTick(obj);
        return;
    end
    LogAlways("newfunc"..tostring(PowerStruggle.OnTick));
end

This hook function, however, does not work. It just prints the original
++++++++++++OnTick++++++++++ rather than both. Also, the LogAlways statement shows the memory address for the function is changing. Anyone have any idea why it's failing? 


Thanks,
James
