Help with reciprocating rect loop

in Programming Questions • 1 year ago

Hi,

I am a noob in processing, and I need a help in reciprocating a block in a loop. I have implemented it. But wanna know if there is any code simpler than this!.

The receiprocation must be in a loop (like the piston in crank slider mechanism).

here is the code what i tried:

int x=300,y=0;
void setup(){
size(640,320);
}
void draw(){
background(0,0,y);
rect(x,200,30,70);
if(y<100)
x++;
y++;
if(y>=100){
x--;}
if(y>200){
y=0;
x=300;}

}

is there any simple way to do it?

Thanks for your help.

Hi thinkanish,

Your code looks pretty simple to me, im not sure much can be done to make it simpler. it's readability could be improved by re-arranging some things, and using else's with your if's:

int x=300,y=0;
void setup(){
size(640,320);
}
void draw(){
background(0,0,y);
rect(x,200,30,70);
if(y<100) {
x++;
} else if (y >= 100 && y < 200) {
x--;
} else if (y > 200) {
y = 0;
x = 300;
}
y++;
}
}

otherwise I think you are pretty simplified already. Note that I re-arranged a few things and it may slightly alter how the sketch runs, specifically the y++ happens at the very end now, so it would never be 0 (as soon as it is set to 0, it is incremented)

hope this helps, otherwise Ill need some more info of what you are trying to optimize.

good luck!
