Algorithm for key buffer (cheat codes)
Jan 20, 2012 at 3:23pm
How are key buffers created in general? (for cheat codes or any general effect of that kind)
E.I.
When entering "cheat codes", the program listens for a series of key presses {e.g. pressing keyA, keyB, keyY, keyX, in a consecutive order}, and then activates an effect afterwards.

Not sure what you're going after here. Could you explain more?

I have an idea, not entirely sure if it will work and I have to go, I can make a class for this when I come home and test the idea further.
Setup for the struct (psuedo-code)
struct CheatCode
int progress (init as 0)
std::string code; (all lower OR uppercase)
function-pointer callback (see http://www.newty.de/fpt/index.html for function pointers)
put these in an array or a list.
Psuedo code for a possible function used by your keyboard callback function when a key is pressed, assuming you have one.
<convert to lower/upper case (the same as code)>
<iterate through cheat codes>
....<is it the the current->progress-th character>
..........<yes: increment current->progress by 1>
..........<no: set current->progress to 0>
....<is the current->progress on code->code.length)>
..........<yes: run callback function>
