Simple timer function

I just need a simple timer function,

for example I need something to repeat every 5-10 minutes
or maybe after half an hour or 25 hours etc.

so now that glutTimerFunc is out of the picture

how can we do this without re-inventing the wheel?

or using something cheap like ofGetMinutes%5==0 or ofGetElapsedTimef()

Here is an example of what I need:


cout<<“start something awesome”<<endl;


bool ofGetTimerAlarmIsTrue(string & begin time, int minutesInFuture){
return …

I tried a quick search in the addons but couldn’t find anything, I might be wrong though.

you can just store the current time and check in update if the time you are waiting for has passed already.

Hi arturo, thank’s for the feedback
Sorry in advance for the whining… :slight_smile: :

here is the story:

I needed to setup a quick sketch I had in mind,

and I needed a way so that I was able to open the project, and set in-situ a timer-list of future events that would occur reliably on certain time maybe days in future and I was hoping to get when that time would be in human time (so I know the duration of time in minutes but not the time itself)

For example now it’s 11:45

I want to get what time would be 159 minutes in the future etc…
or 100324 minutes :smile:

or if you knew the day time get a timer to that

So What I really needed for that was smthng like a callendar class.

That you say getDayInFuture("24/1/16),135) and you get if is friday tuesday etc…

I only had a few hours so I didn’t want to risk a bug
so I wrote the simpliest thing I could came up with to be sure it will work assuming you only went minutes in the future for the timer not days or months or even hours :confused:

class shittyalarmTimer{
textbox nextAlarmInput;//for inputing minutes until next timer
int nextAlarmTime=30;
int minutesleftforAlarm=30;

int resetTimer(int time){
nextAlarmTime = (ofGetMinutes()+time)%60;
return nextAlarmTime;
int getMinutesUntilAlarm(bool force=false){
int curminutes = ofGetMinutes();
if ((curminutes+minutesleftforAlarm%60) != nextAlarmTime) {
while ((curminutes+minutesleftforAlarm)%60!=nextAlarmTime) {
nextAlarmInput.text = ofToString(minutesleftforAlarm);

    return minutesleftforalarm;
bool getIsAlarmTime(){
    return minutesleftforalarm==0;

string getTimeOfNextAlarm(int){
… if int - getCur minutes <0 then ++ one hour
then return bla bla bla so many bugs.


Yes I could write a class with a lot of If statements that would be able to do so , but I was short in time so I was
hoping if anybody had something ready already I am sure it has to be somewhere :slightly_smiling: I also didn’t have the luxury of debugging or affording the class i came up with to not work for whatever reason.
:slight_smile: anyway

again thank’s for the info, I am all set for now
fingers crossed the shittytimer class wont start counting forward instead of backwards in a month :slightly_smiling:

:beer: :beers:
