Hello everyone! :-D

I'm amazed by this Lua language... It does in 25 lines what C++ would do in like 60. O_O

Now, I might not be that new to coding but I am to games... :-P

My game does a change whenever the user presses the triangle button.

However, when that happens, that change occurs many times due to the fact that the button-press checking occurs every time the game loop goes by... Is there any way to determine how long it should be pressed for that change to take place?

I'm sorry about the bad wording and stuff, I'm really new. Help. Thanks! ;-)

Im pretty new so i dunno if you would use my advice. New to programing.
Anywho for lua i use a buttonpress timer so that it doesnt repeat all actions over and over again on press.

initiate timer
checktimer if time >= .05 seconds then

put keypress, code all the pad stuff here
make sure you reset timer afer every keypress

end


Dunno if you can use that. And if there is a better way i would like to know myself.

OK, this kind of works:

[romero126]

Reset the timer each time you press a button..

[Leo28C]

Mhmm... I don't get it... :-/

I mean, how can I check for a button press? Like;

* Push button
* Perform action
* Release button
* Push button
* Perform action
* Release button

Right now, it doesn't wait for the release to perform the action again... What's the way to check for that? Thanks! ;-)

Have a boolean variable to act as a flag to keep track of current state of the button. Each time you read the pad in the game loop:

If button is not down, clear flag.
If button is down, and the flag is not set, then set the flag and perform your action as this is the first time the button was just pressed.
If button is down, and flag is set, then this is a repeated press/held key which you may choose to ignore, or repeat after a time delay or whatever you want, depending on the use

while true do
if not key = Controls.read() then
key = Controls.read()
if key:triangle() then
-- do stuff here
end
end
end

Cheriff's solution worked, many thanks to all of you! ;-)

Can't believe nobody posted this solution. Everybody use's it as far as I knew:

[romero126]

I posted that on the previous post. It just looks a lil diff.

[Altair]

Ah yeah I see now. However yours reads the controls twice, which isn't necessairy. However for the rest it's the same, you're right.

[Altair]

yeps it should, but that wasn't really what it was about

[romero126]

I was drunk as a skunk when i wrote it leave me alone.
