程設Week04

01.先嘗試放背景。
PImage imgBG;
int []x={0,0,0,0,0};
int []y={0,0,0,0,0};
void setup(){
  size(580,326);
  imgBG=loadImage("1.jpg");
}
void draw(){
   background(imgBG);
   circle(x[0], y[0], 40);
}
void mousePressed(){
  x[0] = mouseX;
  y[0] = mouseY;
}

02.設個陣列，因為子彈不會只有一顆。
PImage imgBG;
int []x={0,0,0,0,0};
int []y={0,0,0,0,0};
int n=0;     ///子彈數目，現在用了0顆子彈。
void setup(){
  size(580,326);
  imgBG=loadImage("1.jpg");
}
void draw(){
   background(imgBG);
   for(int i=0;i<5; i++) {
     circle(x[i], y[i], 40);
   }
}
void mousePressed(){
  if(n>=5)return;
  x[n] = mouseX;
  y[n] = mouseY;
  n++;


int []a={1,1,1,0};
size(400,100);
for(int i=0; i<4; i++){
  if(a[i]==1) fill(255,0,0);
  else fill(128);
  rect (i*100,0, 100,100);
 }
}



int [][]a={
  {1,0,0,0,1},
  {0,1,0,1,0},
  {1,1,1,1,0},
  {0,0,1,0,0},
  {1,0,0,0,0}};
size(500,500);
for(int i=0; i<5; i++){
  for(int j=0; j<5; j++){
    if( a[i][j] == 1 ) fill(255,0,0);
  else fill(128);
  rect (j*100,i*100, 100,100);
 }
}

PImage imgBG;
int []x={0,0,0,0,0};
int []y={0,0,0,0,0};
int []r={5,5,5,5,5};
int n=0;
void setup(){
  size(580,326);
  imgBG=loadImage("1.jpg");
}
void draw(){
   background(imgBG);
   for(int i=0;i<5; i++) {
     circle(x[i], y[i], r[i]);
   }
   if(mousePressed) r[now]++;
}
int now=0;
void mousePressed(){
  ///if(n>=5)return;
  x[n] = mouseX;
  y[n] = mouseY;
  now=n;
  n = (n+1)%5;
}
