Program WAITS UNTIL something happens compared to last time it ran, then it starts again?

in Programming Questions • 10 months ago

- I have a program that grabs images from a server that other people submit to.

- It grabs an image from the server & displays that image, then sequentially displays a random image from the web.

- It goes A1, B1, A2, B2, A3, B3, ... " A" being SUBMITTED images, and " B" being random images fetched from google.

The PROBLEM is that if only one " A" image is submitted, ( cat.jpg), the program will display " cat.jpg", then " random1.jpg".

When the program is finished, it starts again, skips past " cat.jpg" as it knows not to display duplicates, and then displays " random2.jpg". It will then just keep on starting over and over again, skipping " cat.jpg" (which it is supposed to do) and displaying random google images, so it ends up being more like A1, B1, B2, B3, B4, etc.

How can I tell the program ONCE IT REACHES THE END, TO STILL RUN, BUT WAIT UNTIL it gets a new A image, and then continue to display a B.

there is allot of code so I guess I will save anyone the headache of reading through it all, but a pseudo mock up of what i want to happen I think would look like this? :

void draw() {

- add images from server into an array

- display an image if its not already in the array (avoiding duplicates)

if there are any new images in that array compared to last time{

- search google for an image

- display the image from google

}

else just wait until there is a new image

}

The part I want to add is in purple...

i'd do work with a boolean timer combination something like, so you don't check every frame:

boolean isNew = false;

timer=0;

in the draw():

if(isNew)

{

also add random image

isNew=false;

}

if(timer>1000){

checkFor new Image. and set the boolean true if you got one.

timer=0;

}

timer++
