About custom functions:

I read somewhere that GlovePIE can call custom functions in .dll files, but never found any good documentation on how to do this. Anyone know more about this?

Another question would be how GlovePIE handles the .dll functions. If we write custom functions in C or C++ which are linear, package them in a dll, and call it in glovePIE, will PIE actually run them linearly? If that were the case it shouldn't be too difficult to calculate relative velocity and position from accelerometer data.

That's a very good question. Hopefully Carl can answer that one whenever he gets around to it.

If you call dll functions, each call to the function should execute linearly (ie once) for every time glovepie calls it.

Since glovepie loops your code, the function call will execute over and over again indefinately until the script stops. This might give the illusion of the function executing non-linearly, but that isn't the case.

Query: Why would a velocity calculation require a dll function call? Is glovepie's math library somehow insufficient for this task?

How about:

[SwedishFrog]

if you think you need goto commands then you probably don't understand that glovepie isn't linear. Glovepie executes your code out of sequence -- It threads the execution of the code to give the illusion of several parts of your code running at once. It also loops automatically back to the top once it reaches the bottom. This fact makes the goto command meaningless. I doubt glovepie even supports goto, but i'm not sure.

Also you should know that goto commands have been 'out of style' in the programming world for quite a while now. This is because they are conducive to hard to read code which is even harder to debug.
