2.打棒球
先做出能偵測拇指的程式
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();//偵測拇指
finger_index.draw();
}
}
========================================================================
畫出方塊加P3D改成3D
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();
PVector dir = finger_index.getDirection();
println(pos);
println(dir);
}
lights();////打光
fill(255,0,255);////顏色
translate(width/2,height/2);/////畫舞台中間
rotateY(radians(frameCount));////讓他轉
box(200,100,100);////大小
}
========================================================================
畫出雞雞
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();
//println(pos);
//println(dir);
}
lights();
fill(255,0,255);
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);//畫圓
sphere(40);
}
popMatrix();
//rotateY(radians(frameCount));
//box(200,100,100);
}
========================================================================
可以用雞雞射子彈了!!!!!!!!!!!!!
import de.voidplus.leapmotion.*;
PVector pos=null,dir=null;
PVector []bullet =new PVector[100];////設100發子彈
PVector []bullet_dir =new PVector[100];
int bulletNow=0;
LeapMotion leap;
void setup(){
size(600,400,P3D);
leap = new LeapMotion(this);
for(int i=0;i<100;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();
//println(pos);
//println(dir);
}
lights();
fill(255,0,255);
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();
fill(0,0,255);
for(int i=0;i<100;i++){
pushMatrix();////設定子彈飛行狀態,注意別寫在外面的pp函式中
translate(bullet[i].x,bullet[i].y,bullet[i].z);
sphere(42);
bullet[i].x += bullet_dir[i].x;
bullet[i].y += bullet_dir[i].y;
bullet[i].z += bullet_dir[i].z;
popMatrix();
}
popMatrix();
}
void keyPressed(){///按空白箭發射
bullet_dir[bulletNow].x=dir.x*10;
bullet_dir[bulletNow].y=dir.y*10;
bullet_dir[bulletNow].z=dir.z*10;
bulletNow++;
}
修改程式改掉子彈射完的bug
void keyPressed(){
bullet[bulletNow].x=0;bullet[bulletNow].y=0;bullet[bulletNow].z=0;
bullet_dir[bulletNow].x=dir.x*10;
bullet_dir[bulletNow].y=dir.y*10;
bullet_dir[bulletNow].z=dir.z*10;
bulletNow++;
if(bulletNow>=100){
bulletNow=0;
}
========================================================================
來做打棒球八
首先做球棒跟球然後用dist的涵式作偵測判斷
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() {//讓球移動
ball.x+=2;
ball.y+=2;
for (Hand hand : leap.getHands ()) {///球棒跟著手移動
pos=hand.getPosition();
}
background(255);
fill(255, 0, 0);
pushMatrix();
translate(pos.x, pos.y, pos.z);
box(300, 30, 30);
popMatrix();
pushMatrix();
translate(ball.x,ball.y);///碰撞偵測
sphere(30);
if(dist(ball.x,ball.y,pos.x,pos.y)<30){
background(255,0,0);
ball.x-=300;
ball.y-=300;
}
popMatrix();
}
