滑到哪就畫到哪

滑鼠點擊 滑到哪才畫到哪

void setup()
{
  size(800,600);
  background(#FF8383);
}

void draw()

{
  if(mousePressed)
    line(mouseX, mouseY, pmouseX, pmouseY);
}

建立色塊 可換色筆顏色

void setup()
{
  size(800,600);
  background(#FFFFFF);
  stroke(#FF0D00);
}

void draw()
{
  fill(0,255,0); rect(0,0,100,100);
  fill(0,0,255); rect(0,100,100,100);
  fill(255,255,0); rect(0,200,100,100);
}

void mouseDragged()
{
  line(mouseX, mouseY, pmouseX, pmouseY);
}

void mousePressed()
{
    if(mouseX<100 && mouseY<100){ stroke(0,255,0); }
 
    else if(mouseX<100 && mouseY<200){ stroke(0,0,255); }
 
    else if(mouseX<100 && mouseY<300){ stroke(255,255,0); }

}

點右邊空白處 越往下 筆刷會越粗

void setup()
{
  size(800,600);
  background(#FFFFFF);
  stroke(#FF0D00);
}

float mystrokeCrude=1;
color mystroke=color(0);

  fill(0,0,255); rect(0,100,100,100);
  fill(255,255,0); rect(0,200,100,100);
  stroke(mystroke); strokeWeight(mystrokeCrude);
}
