寫出文字
size(500,500);
textSize(64);
text("Hello World", 100,100);
fill(255,0,0);
text("Red", 100,200);
能在視窗打出文字
void setup(){
size(500,500);
textSize(64);
}
String line = "Input: ";
void draw(){
text(line,100,100);
}
void keyPressed(){
line += key;
}
不要打出特殊符號
void setup(){
size(500,500);
textSize(64);
}
String line = "Input: ";
void draw(){
text(line,100,100);
}
void keyPressed(){
if(key>='A' && key<='Z') line += key;
if(key>='a' && key<='z') line += key;
}
刪掉文字但不能刪掉Input並且不能當機
void setup(){
size(500,500);
textSize(64);
}
String line = "";
void draw(){
background(0);
text("Input: "+line,100,100);
}
void keyPressed(){
if(key>='A' && key<='Z') line += key;
if(key>='a' && key<='z') line += key;
if(key==BACKSPACE && line.length()>0){
line = line.substring(0, line.length()-1);
}
}
安裝聲音的函式
在程式中加入聲音
import processing.sound.*;
SoundFile file;
void setup(){
size(300,300);
file = new SoundFile(this, "a.mp3");
file.play();
}
void draw(){
}
按數字鍵發出不同的聲音
import processing.sound.*;
SoundFile dadada, good, over;
void setup(){
size(300,300);
dadada = new SoundFile(this, "dadadadada.mp3");
good = new SoundFile(this, "good.mp3");
over = new SoundFile(this, "over.mp3");
}
void draw(){
text("press 1, 2, 3",100,100);
}
void keyPressed(){
if(key=='1') dadada.play();
if(key=='2') good.play();
if(key=='3') over.play();
}
聲音程式跟按鍵程式結合
import processing.sound.*;
SoundFile da, dingdong, ouch;
void setup(){
size(800,400);
textSize(64);
da = new SoundFile(this, "da.mp3");
dingdong = new SoundFile(this, "dingdong.mp3");
ouch = new SoundFile(this, "ouch.mp3");
}
String line = "";
void draw(){
background(0);
text("Input: "+line,50,100);
}
void keyPressed(){
if(key>='A' && key<='Z') { line += key; da.play(); }
if(key>='a' && key<='z') { line += key; da.play(); }
if(key==BACKSPACE && line.length()>0){
line = line.substring(0, line.length()-1);
ouch.play();
}
if(key==ENTER){
dingdong.play();
}
}
先做出點、字還有線
void setup(){
size(400,600);
textSize(20);
}
String Q="hello", A="";
float x = 100, y = 100;
void draw(){
background(0);
text(Q, x, y);
ellipse(200,550, 20,20);
float dx = (200-x), dy = (550-y), d = sqrt(dx*dx+dy*dy)*3;
x += dx / d;
y += dy / d;
if(keyPressed){
stroke(255,0,0);
line(200,550, x, y);
}
}
輸入對的文字就變顏色
void setup(){
size(400,600);
textSize(20);
}
String Q="hello", A="";
float x = 100, y = 100;
void draw(){
background(0);
fill(#FFFFFF); text(Q, x, y);
fill(#FF0000); text(A, x, y);
ellipse(200,550, 20,20);
float dx = (200-x), dy = (550-y), d = sqrt(dx*dx+dy*dy)*3;
x += dx / d;
y += dy / d;
if(keyPressed){
stroke(255,0,0);
line(200,550, x, y);
}
}
void keyPressed(){
int i = A.length();
if( key == Q.charAt(i) ) {
A += key;
}
}
輸入正確答案字會消失並跑出新的字，每個字的出現位置不同
void setup(){
size(400,600);
textSize(20);
randomQ();
}
void randomQ(){
int i = int(random(QQ.length));
Q = QQ[i];
x = random(0,300);
y = random(0,100);
}
String [] QQ = { "void", "setup", "float", "string", "background", "fill"};
String Q = "hello", A = "";
float x = 100, y = 100;
void draw(){
background(0);
fill(#FFFFFF); text(Q, x, y);
fill(#FF0000); text(A, x, y);
ellipse(200,550, 20,20);
float dx = (200-x), dy = (550-y), d = sqrt(dx*dx+dy*dy)*3;
x += dx / d;
y += dy / d;
if(keyPressed){
stroke(255,0,0);
line(200,550, x+textWidth(A), y);
}
}
void keyPressed(){
int i = A.length();
if( key == Q.charAt(i) ) {
A += key;
if( Q.equals(A) ){
randomQ();
A = "";
}
}
}
