一筆成型的畫
void setup(){
size(600,400);
}
void draw(){
line(pmouseX,pmouseY,mouseX,mouseY);先前的滑鼠pre畫到新的滑鼠作標
}
void setup(){
size(600,400);
}
void draw(){
if (mousePressed){ 滑鼠按下去才會畫畫
line(mouseX,mouseY,pmouseX,pmouseY);
}
}
void setup(){
size(600,400);
}
void draw(){
stroke(#FF0DD3);可以改顏色
if (mousePressed){
line(mouseX,mouseY,pmouseX,pmouseY);
}
}
按按鍵，改顏色或粗細
void setup(){
size(600,400);
}
void draw(){
if(key=='1')stroke(255,0,0);按1畫出紅色
if(key=='2')stroke(255,255,0);按2畫出黃色
if(key=='3')stroke(0,255,0);按3畫出綠色
if(key=='4')strokeWeight(4);按4變粗
if(key=='5')strokeWeight(10);按5變粗
if (mousePressed){
line(mouseX,mouseY,pmouseX,pmouseY);
}
}
小畫家
void setup() {
size(600, 400);
fill(255, 0, 0);畫左上角調色盤
rect(0, 0, 50, 50);
fill(255, 255, 0);畫左上角調色盤
rect(0, 50, 50, 50);
fill(0, 255, 0);畫左上角調色盤
rect(0, 100, 50, 50);
fill(0, 255, 255);畫左上角調色盤
rect(0, 150, 50, 50);
fill(0, 0, 255);畫左上角調色盤
rect(0, 200, 50, 50);
fill(255);整個黑色框框
rect(0, 250, 50, 150);
line(25, 250, 25-7, 400);畫三角形條粗度
line(25, 250, 25+7, 400);
}
void draw() {
if (mouseX<50 && mousePressed) {
if (mouseY<50)stroke(255, 0, 0);用點選位置判斷應該畫出的顏色
else if (mouseY<100)stroke(255, 255, 0);
else if (mouseY<150)stroke(0, 255, 0);
else if (mouseY<200)stroke(0, 255, 255);
else if (mouseY<250)stroke(0, 0, 255);
else {
strokeWeight((mouseY-250)/10);調整粗度
}
}
if (mousePressed) { 畫畫
line(mouseX, mouseY, pmouseX, pmouseY);
}
}
