期中作品:跳躍障礙物小遊戲
今天主要是延續上禮拜2D轉變為3D翻轉手指畫圈
程式碼如下:
import de.voidplus.leapmotion.*;
LeapMotion leap;
PVector [][] pt=new PVector[5][100];
void setup() {
size(640, 480, P3D);//視窗大小(前面不能有程式!會有錯誤!)
for (int f=0; f<5; f++) { //五隻手指頭
for (int i=0; i<100; i++) //每隻手指頭有100個點
pt[f][i]=new PVector(0, 0, 0);
}
leap=new LeapMotion(this);
colorMode(HSB, 100);
}
void draw() {
background(0);
stroke(#63F0E5);
for (int f=0; f<5; f++) {
for (int i=99; i>0; i--) {
pt[f][i].x=pt[f][i-1].x;
pt[f][i].y=pt[f][i-1].y;
}
}
for (Hand hand : leap.getHands ()) {
for (Finger finger : hand.getFingers ()) {
int f=finger.getType();
PVector now=finger.getPosition();
pt[f][0].x=now.x;
pt[f][0].y=now.y;
if (f==1) println(now);
}
}
translate(width/2, height/2);
rotateY(radians(frameCount));
translate(-width/2, -height/2);
for (int f=0; f<5; f++) {
for (int i=1; i<100; i++) {
stroke(f*20, 100, 100);
line(pt[f][i].x, pt[f][i].y, pt[f][i].z, pt[f][i-1].x, pt[f][i-1].y, pt[f][i-1].z);
}
}
stroke(60, 100, 100);
for (int i=0; i<640; i+=20)
for (int j=0; j<480; j+=20) {
noFill();
rect(i, j, 20, 20);
}
}
接下來這個是要畫出有調色盤的感覺 利用雙手控制
程式碼如下:
import de.voidplus.leapmotion.*;
LeapMotion leap;
void setup() {
size(640, 480, P3D);
leap=new LeapMotion(this);
}
color nowColor = color(255, 0, 0);
PVector leftPos;
void draw() {
background(255);
for (Hand hand : leap.getHands () ) {
PVector pos = hand.getPosition();
if (hand.isLeft()) {
noFill();
ellipse(pos.x, pos.y, 200, 100);
fill(255, 0, 0);
ellipse(pos.x+150, pos.y, 60, 50);
fill(255, 255, 0);
ellipse(pos.x+120, pos.y-40, 60, 50);
fill(0, 255, 0);
ellipse(pos.x+90, pos.y-60, 60, 50);
fill(0, 0, 255);
ellipse(pos.x+30, pos.y-60, 60, 50);
fill(255, 0, 255);
ellipse(pos.x-20, pos.y-60, 60, 50);
leftPos = pos;
} else if (hand.isRight()) {
fill(nowColor);
rect(pos.x, pos.y, 10, 100);
println(leftPos);
println(pos);
if (dist(pos.x, pos.y, leftPos.x+120, leftPos.y-40) <30) {
nowColor = color(255, 255, 0);
}
}
}
}
