1-1. 首先用Processing找出食指
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(); 畫出食指
}
}
1-2. 做出一個3D的方塊(之後要把方塊套到食指上)
import de.voidplus.leapmotion.*;
LeapMotion leap;
void setup(){
size(600,400,P3D); //畫3D
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(); //食指位置
PVector dir = finger_index.getDirection(); //食指方向
println(pos);
println(dir);
}
//lights();
fill(255,0,0);
translate(width/2, height/2);
rotateY(radians(frameCount)); //自轉
box(300,100,100);
}
1-3. 做出圓球會隨著手轉、移動
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++){ //*10次
if(dir!=null) translate(dir.x*10*i, dir.y*10*i,dir.z*10*i); //如果方向不為空,就會改變
sphere(40); //畫出圓
}
popMatrix();
}
1-4. 會發射子彈
import de.voidplus.leapmotion.*;
LeapMotion leap;
PVector pos=null,dir=null;
PVector[] bullet=new PVector[10]; //子彈陣列(位置)
PVector[] bullet_dir=new PVector[10]; //子彈陣列(方向)
int bulletNow=0; //子彈數量
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();
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();
pushMatrix(); //子彈
fill(0,0,255);
for(int i=0;i<10;i++){
pushMatrix();
translate(bullet[i].x, bullet[i].y, bullet[i].z); //位置
sphere(41);
bullet[i].x += bullet_dir[i].x; //轉動x,y,z
bullet[i].y += bullet_dir[i].y;
bullet[i].z += bullet_dir[i].z;
popMatrix();
}
popMatrix();
}
void keyPressed(){
bullet_dir[bulletNow].x = dir.x*5;
bullet_dir[bulletNow].y = dir.y*5;
bullet_dir[bulletNow].z = dir.z*5;
bulletNow++;
}
※有bug,發10顆會當掉
2-1打棒球
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);
popMatrix();
}
