作業(一) 用滑鼠畫畫
void setup()
{
size(600,400);
}
void draw()
{
line (mouseX,mouseY,pmouseX,pmouseY);
}
作業(二) 用滑鼠畫畫 ---調整粗細以及顏色
void setup()
{
size(600,400);
}
void draw()
{
if(key=='1')stroke(255,0,0); ///顏色(紅色)
if(key=='2')stroke(255,255,0); ///顏色(黃色)
if(key=='3')stroke(0,255,0); ///顏色(綠色)
if(key=='4')strokeWeight(4); ///粗細
if(key=='5')strokeWeight(10); ///粗細
if(mousePressed)
{
line (mouseX,mouseY,pmouseX,pmouseY);
}
}
作業(三) 用滑鼠畫畫 ---用滑鼠點顏色和粗細
