Create a delay?

Hi, I wanted to create a delay in my game once for a second and searched for a function and found the Delay(); function but the wiki says:

delay() has been removed. Nobody understood what it did, and when they did, they didn't understand why it was there. Huge source of confusion, especially for beginning students.

So how can I reproduce the effect of this function?

Thanks in advance.

You can do something similar to this... this is just a timer though that does something every X seconds.

Copy code

long lastTime = 0;
void setup() {
lastTime = millis();
}
void draw() {
if ( millis() - lastTime > 5000 ) {
println( "do things every 5 seconds" );
lastTime = millis();
}
}

Delay was a bad thing because it halted the whole program, including the GUI - which means that buttons etc would stop to react and the user would think the program had crashed (or worse).

or you can make your own like this:

Copy code

void setup()
{
size(100,100);
}
boolean on = false;
void draw()
{
if(on) background(255,0,0);
else background(0);
on = !on;
myDelay(6000);
}
void myDelay(int ms)
{
try
{
Thread.sleep(ms);
}
catch(Exception e){}
}

delay() is back since 2.0a5.

Yes, but it is still a bad idea to use it, because it halts your program which becomes unresponsive until delay() is finished.

(BTW, you answer to a one year old thread! Not sure of your point.)
