南崁金城武-Week04

今天先寫了一個按滑鼠會有點點的

PImage BG;
int []x={0,0,0,0,0};
int []y={0,0,0,0,0};
int n=0;
void setup()
{Week
    size(768,1280);
    BG=loadImage("back.png");
}
void draw()
{
    background(BG);
    for(int i=0;i<5;i++)
    {
        circle( x[i],y[i],40);
    }
}
void mousePressed ()
{
    x[n]=mouseX;
    y[n]=mouseY;
    n=(n+1)%5;
}
還有圖像陣列
