Input tags debouncing

[cpat]

Hi guys,

As I'm typing with a keyboard with the command GD.cmd_keys, I've got several inputs of a key stroke because of the looping function while the key is still pressed.
Is there any workaround (adding a delay() function is obviously not the solution). How can I disable the GD.inputs.tag in the Library ?

Well, the tag hardware just reports raw touches - a lot like the keys on a keyboard. So there needs to be some software state machine that processes the tags.

What I normally do is keep track of the tag from the previous cycle, and when the previous tag is zero, and the current tag is <something>, it means that this is the first press.

static int prev_tag = -1;

...

GD.get_inputs();

if ((prev_tag == 0) && (GD.inputs.tag == 100)) {
 // 100 was pressed for the first time
}
// etc

prev_tag = GD.inputs.tag;

Very clever way to achieve what I wanted, thanks !
