2.打棒球練習
***************************************************************
01.砲彈遊戲園裡練習
首先,秀食指
import de.voidplus.leapmotion.*;
LeapMotion leap;
void setup(){
size(600,400);
leap = new LeapMotion(this);
}
void draw(){
background(255);
for(Hand hand : leap.getHands()){
Finger finger_index = hand.getIndexFinger();
finger_index.draw();
}
}
畫出長方體
import de.voidplus.leapmotion.*;
LeapMotion leap;
void setup(){
size(600,400, P3D);
leap = new LeapMotion(this);
}
void draw(){
background(255);
for(Hand hand : leap.getHands()){
Finger finger_index = hand.getIndexFinger();
finger_index.draw();
PVector pos = finger_index.getPosition(); //食指現在的位置
PVector dir = finger_index.getDirection(); //食指現在的方向
println(pos);
println(dir);
}
lights(); //打光讓物體看起來有立體感
fill(255,0,0);
translate(width/2, height/2); //使物體的位置出現在畫面正中心
rotateY(radians(frameCount)); //使物體旋轉
box(300,100,100); //畫出盒子
}
把長方體改球體,並設計路方向使移動時有殘影出現
import de.voidplus.leapmotion.*;
LeapMotion leap;
void setup(){
size(600,400, P3D);
leap = new LeapMotion(this);
}
PVector pos=null, dir=null;
void draw(){
background(255);
for(Hand hand : leap.getHands()){
Finger finger_index = hand.getIndexFinger();
finger_index.draw();
pos = finger_index.getPosition();
dir = finger_index.getDirection();
}
lights();
fill(255,0,0);
pushMatrix();
translate(width/2, height/2);
for(int i=0;i<10;i++){
if(dir!=null)
translate(dir.x*10*i, dir.y*10*i, dir.z*10*i);
sphere(40);
}
popMatrix();
}
增設按空格鍵發射出子彈
import de.voidplus.leapmotion.*;
PVector pos=null, dir=null;
PVector []bullet=new PVector[10];
PVector []bullet_dir=new PVector[10];
int bulletNow=0;
LeapMotion leap;
void setup(){
size(600,400, P3D);
leap = new LeapMotion(this);
for(int i=0;i<10;i++){
bullet[i]=new PVector(0,0,0);
bullet_dir[i]=new PVector(0,0,0);
}
}
void draw(){
background(255);
for(Hand hand : leap.getHands()){
Finger finger_index = hand.getIndexFinger();
finger_index.draw();
//pos = finger_index.getPosition();
dir = finger_index.getDirection();
}
lights();
fill(255,0,0);
translate(width/2, height/2);
pushMatrix();
for(int i=0;i<10;i++){
if(dir!=null)
translate(dir.x*10*i, dir.y*10*i, dir.z*10*i);
sphere(40);
}
popMatrix();
fill(0,0,255);
for(int i=0;i<10;i++){
pushMatrix();
translate(bullet[i].x, bullet[i].y, bullet[i].z);
sphere(41);
bullet[i].x += bullet_dir[i].x;
bullet[i].y += bullet_dir[i].y;
bullet[i].z += bullet_dir[i].z;
popMatrix();
}
}
void keyPressed(){
bullet[bulletNow].x=0;bullet[bulletNow].y=0;bullet[bulletNow].z=0;
bullet_dir[bulletNow].x = dir.x*5;
bullet_dir[bulletNow].y = dir.y*5;
bullet_dir[bulletNow].z = dir.z*5;
bulletNow++;
if(bulletNow>=10){
bulletNow=0;
}
}

02.棒球遊戲原理練習
import de.voidplus.leapmotion.*;
LeapMotion leap;
PVector pos, dir, ball;
void setup(){
size(600, 400, P3D);
leap = new LeapMotion(this);
pos = new PVector(300,200,0);
ball=new PVector(0,0,0);
}
void draw(){
ball.x +=2;
ball.y +=2;
for(Hand hand : leap.getHands()){
pos = hand.getPosition();
}
background(255);
fill(255,0,0);
pushMatrix();
translate(pos.x, pos.y, pos.z);
box(30,30,30);
popMatrix();
pushMatrix();
translate(ball.x, ball.y);
sphere(30);
if(dist(ball.x, ball.y, pos.x, pos.y)<30)
background(255,0,0);
popMatrix();
}
