Running some code just one time insde void draw
Aug 13th, 2009, 6:29pm  
Hello
I'm working on a program that communicates with a pic mcu via rs232. Inside this program i have an array that i need to read and store data retrieved from the mcu, but i don't need to do this on every frame so i think the better way to do this is just running through this piece of code just one frame once a time based conditional is fulfilled.
How will be the best way to acomplish this?

Thanks

There are two ways to achieve it.

First one: assuming your sketch's frameRate is set to 60, it will then run your array once every second.

Code:
int runonce = 0;
 if(runonce <= 60){ 
  runonce = runonce+1;
}
else{
// Call your array here
runonce = 0;
}


Second one: make use of boolean.

Code:
if(ConditionReached){ 
// your array here
}

One slight modification to avoid problems:

Code:
if(ConditionReached){ 
// your array here
ConditionReached=false;
}

Thanks for the answers. I'm working on the code right now and it seems to work just fine.

Thanks again
