Cheat Engine

I've wrote a pretty serviceable lua script for finding and registering coordinates for my player in a unity game. I want to be able to skew myself around the map. It works when I do it manually in CE so this script is meant to automate the process of finding and assigning hotkeys. The problem is that when I call a generic function with the hotkeys and pass variables ("birdx" and an integer to move by) to it like so:

hk_XMinus1 = createHotkey( Warp( "birdx", -1 ), VK_X, 189);

...it works on the first pass through the script but subsequent calls produce the "Attempt to call nil value" error. It won't even get into the function-- I've proven this by using a debug print message at the beginning of the function.

So, I figure that what's happening is that somehow the hotkey assignment loses the variables after it runs once or during initial script execution. It works fine if I just reduce it to one function for each movement, like this:

hk_XMinus1 = createHotkey( WarpXUp1, VK_X, 189);

But that seems so 'uncivilized.' Is there a way to use a global variable or some other method to keep CE for losing track of the variables assigned to the function a hotkey is calling??

It was supposed to be a "function name(sender)" calling method with sender the GenericHotkey object returned by createHotkey, where you can then lookup the sender in a list and decide what to do with it.
But it seems that's broken...
So yeah, for now use different functions

Thanks for the quick reply, DarkByte. Sorry I seem to have found a flaw in what has otherwise been a totally awesome bag of tools. Thanks for all you do!

For the record, this is what I did to make it work and save a little bit of redundancy in the code:

1) Used something like this to define the hotkeys:
hk_XMinus1 = createHotkey( WarpXUp1, VK_X, 189 );

2) The WarpXUp1 function is used to supply variables to the Warp function...looks like this:
function WarpXUp1( )
Warp( "birdx", 1 );
return true;
end

3) And then I use one function to actually do the work:
function Warp( sym, factor )
v = readFloat( sym );
writeFloat( sym, v + factor );
beep()
return v + factor;
end
