2. 檔案讀取、寫檔
3. 排名
4. ArrayList 與資料結構
小畫家
void setup(){
size(600,600);
}
void draw(){
if(mousePressed) line(mouseX,mouseY,pmouseX,pmouseY);
}
void keyPressed(){
save("now.png");
}
按任意鍵存檔
sketch(速寫本)→Show Sketch Folder(打開程序目錄)→即可找到剛剛存的圖檔
避免存檔覆蓋
 |
| 檔名會自動存成 now_XXX |
void setup(){
size(600,600);
}
void draw(){
if(mousePressed) line(mouseX,mouseY,pmouseX,pmouseY);
}
int number=0;
void keyPressed(){
//save("now.png");
save("now_" + number + ".png");
number++;
}
存檔(saveFrame)
 |
| 檔名會以screen命名 |
void setup(){
size(600,600);
}
void draw(){
if(mousePressed) line(mouseX,mouseY,pmouseX,pmouseY);
}
//int number=0;
void keyPressed(){
saveFrame();
//save("now.png");
//save("now_" + number + ".png");
//number++;
}
遊戲玩完存檔(saveString)
String [] names={"AAA","BBB","CCC"};
saveStrings("myClassmateName.txt",names);
*ctrl+K 開檔案資料夾
可以存檔讀檔案或網址
可以是檔名或網址
↓
String lines[]=loadStrings("myClassmateName.txt");
println("there are"+lines.length+"lines");
for(int i=0;i<lines.length;i++){
println(lines[i]);
