void setup()
{
size(400,400);
}
void draw()
{
background(255);
line(mouseX, mouseY, pmouseX, pmouseY);
}
void mouseReleased()//滑鼠畫畫滑鼠放開會清空
{
background(255);
}
Step 01-2 用圓圈家黑色的直線當作鬼 靠近中心圓圈
void setup()
{
size(400,400);
background(255);
}
float ghostX = 400, ghostY = 20;
void draw()
{
ellipse(200,200,15,15);
if(mousePressed) line(mouseX, mouseY, pmouseX, pmouseY);
ellipse(ghostX,ghostY,15,15);
float dx = 200-ghostX, dy = 200-ghostY , len = sqrt(dx*dx+dy+dy);
ghostX += dx / len / 3;
ghostY += dy / len / 3;
}
void mouseReleased()//滑鼠畫畫滑鼠放開會清空
{
background(255);
}
step01-3 加一個留下慘影的Arraylist
ArrayList<PVector> pt = new ArrayList<PVector>();//大資料結構裡面有小資料結構 pt是點
void setup()
{
size(400,400);
background(255);
}
float ghostX = 400, ghostY = 20;
void mouseDragged()//按下mouse鍵 再拖它
{
pt.add( new PVector(mouseX, mouseY) );
}
void draw()
{
ellipse(200,200,15,15);
//if(mousePressed) line(mouseX, mouseY, pmouseX, pmouseY);
for ( int i=0; i<pt.size(); i++ )
{
PVector p = pt.get(i);
ellipse(p.x, p.y, 3, 3);
}
ellipse(ghostX,ghostY,15,15);
float dx = 200-ghostX, dy = 200-ghostY , len = sqrt(dx*dx+dy+dy);
ghostX += dx / len / 3;
ghostY += dy / len / 3;
}
void mouseReleased()//滑鼠畫畫滑鼠放開會清空
{
background(255);
}
step 01-4 滑鼠放開 圓圈被移除
把圓圈改成線 畫完不會留下殘影
ArrayList<PVector> pt=new ArrayList<PVector>();
void setup(){
size(400,400);
background(255);
}
float ghostX=400,ghostY=20;
void mouseDragged()

}
ellipse(ghostX,ghostY,15,15);
float dx=200-ghostX,dy=200-ghostY,len=sqrt(dx*dx+dy*dy);
ghostX+=dx/len/3;
ghostY+=dy/len/3;
}
void mouseReleased(){
for(int i=pt.size()-1;i>=0;i--)
{
pt.remove(i);
}
}
step 02-1 如果橫線化超過100 變紅色的橫線 不是 就是黑色的線
ArrayList<PVector> pt=new ArrayList<PVector>();
void setup(){
size(400,400);
background(255);
}

//if(mousePressed)line(mouseX,mouseY,pmouseX,pmouseY);
ellipse(ghostX,ghostY,15,15);
strokeWeight(4);//線的粗度
float dpx = 0, dpy = 0;//要看 p.x p2.x的差距 p.y p2.y的差距
for(int i=0;i<pt.size()-1;i++)
{
PVector p = pt.get(i),p2 = pt.get(i+1);
dpx += abs(p2.x - p.x);//累積x的移動量
dpy += abs(p2.y - p.y);//累積y的移動量
}
if ( dpx>100 && dpy<40 ) stroke(255,0,0);//type紅色的橫線
else stroke(0);//不是 就黑色線
for(int i=0;i<pt.size()-1;i++)
{

line(p.x,p.y,p2.x,p2.y);
}
ellipse(ghostX,ghostY,15,15);
float dx=200-ghostX,dy=200-ghostY,len=sqrt(dx*dx+dy*dy);
ghostX+=dx/len/3;
ghostY+=dy/len/3;
}
void mouseReleased(){
for(int i=pt.size()-1;i>=0;i--)
{
pt.remove(i);
}
}
stpe 02-2 直的畫 夠多會變藍色的直線

}
if ( dpx>100 && dpy<40 ) stroke(255,0,0);//type紅色的橫線
else if (dpx<40 && dpy>100 ) stroke(0,0,255);//type2 藍色的直線

}
void mouseReleased(){

step 02-3 當x 增加 y也增加的時候(往右下的斜線) 變綠色的線
