Rotation cube problem

edited September 2017 in Questions about Code

Hey, I'm new at processing code and I'm doing a little code for the mouvement of a finger (the index). I'm doing it with the rotation of phalanges, remplaced by cube.

But I have a big problem, the third box 's rotation isn't what I want, I don't know how to explain it but here is my code. How to fix this and have a good mouvement of index ? Thanks for the help.

int a = 80;
int z = 0;
int e =50;
int r = 60;
float rot1;//rotation of cube_1
float rot2;//rotation of cube_2
float rot3;//rotation of cube_3




void setup() {
  size(400, 400, P3D);
  smooth();
}

void  draw() {
  background(20, 50, 80);

  //base
  translate(width/4, height/4);
  box(80, 50, 50);
  pushMatrix();
  // 1/2/3
  translate(a, z);//1
  rotateZ(rot1);
  box(r, e, e);
  translate(a, z);//2
  rotateZ(rot2);
  box(r, e, e);

  translate(a, z);//3
  rotateZ(rot3);
  box(r, e, e);
  popMatrix();

  if  (keyPressed == true)
  {
    if (key =='a') {  //Rot1
      rot1 = rot1 + 0.01;
    } else if (key == 'z') {
      rot1 = rot1 - 0.01;
    }

    if (key =='a') { //rot2
      rot2 = rot2 + 0.01;
    } else if (key == 'z') {
      rot2 = rot2 - 0.01;
    }

    if (key =='a') { //rot3
      rot3 = rot3 + 0.01;
    } else if (key == 'z') {
      rot3 = rot3 - 0.01;
    }
  }

  if (rot1 > 1.5) {
    rot1 = 1.5;
  } else if (rot1 < -0.5) {
    rot1 = -0.5;
  }
  if (rot2 > 1.0) {
    rot2 =60;
  } else if (rot2 < 0.0) {
    rot2 = 0.0;
  }
  if (rot3 > 1.5) {
    rot3 = 1.5;
  } else 
  if (rot3 < 0) {
    rot3 = 0;
  }
  println(rot3);
}

    On line 64, you have a value of 60. This seems wrong. Shouldn't it be a 1?

    Yeah ! Thanks a lot, I read over this code a few time and never seen this mistake. Now I can do the rest of the hand. What's better ? : pushMatrix()/popmatrix() functions or there is an other way more optimized than push/pop matrix functions ? Thanks for the help !

    pushMatrix()/popMatrix() are optimised already, so I doubt if there is a more efficient way.
    They both just push and pop the Transformation matrix to and from a stack of it.
