How to use array and for loop in my case?? please help

chuckjai

Hello guys, i am bad at english, hope you guys understand what i'm talking about. I am working on my assignment of processing, i would like to create a mini game like NS SHAFT. I want 3 object move from the bottom to the top,

in my code , obsX is the x position, obsY is y position:

obsX=int(random(-50, width-200));

obsY=height-100;

obsX2=int(random(-50, width-200));

obsY2=height+200;

obsX3=int(random(-50, width-200));

obsY3=height+400;

obsWidth=200;

obsHeight=100;

obsSpeed=5;

and i write a function call wood to make it move those objects upward:

void wood() {

image(cloud,obsX, obsY, obsWidth, obsHeight); obsY=obsY-obsSpeed;

image(cloud,obsX2, obsY2, obsWidth, obsHeight); obsY2=obsY2-obsSpeed;

image(cloud,obsX3, obsY3, obsWidth, obsHeight); obsY3=obsY3-obsSpeed;

}

How could i use array and for loop to simplify the code??

float[] x = {random(585),random(585),random(585),random(585),random(585),random(585)};
float[] y = {0,100,200,300,400,500};

void setup(){
  size(600,600);
}

void draw(){
  background(0);
  for(int i=0;i<x.length;i++){
    rect(x[i],y[i],30,5);
    y[i]--;
    if(y[i]<-5){
      y[i]=height;
      x[i]=random(width-30);
    }
  }
}

excuse me, can you teach me how to detect the rectangle when it touch the character? ^:)^

See other thread

Just use dist() in a for-loop with i
