各位前辈好我是刚学processing的菜鸟下面这行代码显示不了....
Tunnel oursGame = new Tunnel(0.1);//float a;
float x, y;
int depth;
void setup() {
size(1200, 800, P3D);
}
void draw() {
background(0);
translate(width/2.0, height/2.0-100, 0);
pushMatrix();
translate(0, 200 ,300);
lights();
noStroke();
fill(#E3C26E);
box(50);
popMatrix();
oursGame.display();
oursGame.speedMove();
float anger = atan2(mouseY-100,mouseX-100);
rotate(anger);
rotate(x);
if ((keyPressed)&&(key == 'a')) {
x+=0.1;
}
if ((keyPressed)&&(key == 'd')) {
x-=0.1;
}
translate(0, 0, -80);
}
class Tunnel{
// default values for a Tunnel
color colour = color(0, 255, 0);
//int tunnelNumber= 1;
float speed;
float c;
int i;
// array of blocks in the tunnel
Block[] blocks = new Block;
//constructor
Tunnel (float tempspeed) {
speed = tempspeed;
blocks = new Block(0);
}
//method
void display(){
for (int i =blocks.length-1;i > 0; i--) {
blocks = blocks;
}
blocks = blocks;
}//constructor
void speedMove()
{
translate(0,100, c);
c+=speed;
}
}//tunnel
//====================================================
class Block {
//default values for 4 blocks
float x ;
float y ;
float z ;
float angle ;
float roadlocation;
float len;
//float tempspeed
Block(float tempZ ) {
angle = (float)random(0, 2*PI);
len = random(10,200);
//speed = tempspeed;
z = tempZ;
//set randomthe angle of the blockseconda il centro
if ( (( 0<=angle)&&(angle<PI/2)||(PI<=angle)&&(angle<3/2*PI))) {
x = -100*sin(angle);
y = +100*cos(angle);
}
if ((( PI/2<=angle)&&(angle<PI)||(3/2*PI<=angle)&&(angle<2*PI))) {
x = +100*sin(angle);
y = -100*cos(angle);
}
}
//set the random rotate
void display() {
noStroke();
pointLight( 255, 200, 0, width / 2, height / 2, 400 );
directionalLight(0, 255, 255, 0, -1, 0);
println(roadlocation);
if ((0<= angle)&&(angle<PI)) {
rotate(PI/2-angle);
}
if ((PI <= angle)&&(angle<2*PI)) {
rotate(PI/2+angle);
}
//4 blocks in a plane
for (int i =0; i<4; i++) {
pushMatrix();
translate(x, y, 0);
fill(200, 122, 255);
box(30,30,len);
popMatrix();
}
}
} 能运行，没有报错，结果只有一个正方形。
