I dunno this IDE. Maybe the Dice class is not where it should be

Ive actullay been getting this error now Implicit super constructor sketch_230824b.CollisionDetector() is undefined. Must explicitly invoke another constructor here is my constructor Avatarang(int x, int y, int z, int scale) within my code onyl error im getting

You're getting that error on a constructor in a class that is defined as public class MyClass extends Something. As in, it has an 'extends' on it.

All constructors start with super(). They just do. If you fail to write it, javac assumes you forgot and acts like it's there. The only way to avoid it is either [A] add a this() call (not relevant here, just mentioning it to be complete), or [B] you explicitly add it, or some other super(someArgs) call.

So, your constructor starts with it too. And the thing is, your parent class does not have a no-args constructor. So, javac silently acts like super(); is up top, and then fails on this invisible statement because it is referring to a non-existent constructor. The solution is to stick super(some, args, here); up top. Without seeing the code/API of the superclass I couldn't tell you what it should look like.

Now, object does have a no-arguments constructor, which is why I know this error must be occurring on a class that extends something. (because all classes extend something. If you fail to mention that, javac acts like you wrote extends java.lang.Object). Javac does a number of these implicit things 🙂

Ahh ok I understand so is the super class suppose to resemble the parent class or the current class its currently in ?

   super(avx,avy,avz,spdx,spdy,spdz,avscale,0,0,0);

  
  
    float x, y, z;
    float scale;

    Avatarang(int x, int y, int z, int scale) {
        this.x = x;
        this.y = y;
        this.z = z;
        this.scale = scale;
    }

    void display() {
        pushMatrix();
        translate(x, y, z);
        scale(scale);

    }
    
       
    
   void move() {
    // get ready for movement in next frame.
    myx = round(myx + speedX) ;
    myy = round(myy + speedY) ;
    myz = round(myz + speedZ);
    detectCollisions();
  }  
    
  
    int [] getBoundingBox() {
    int [] result = new int[6];
    result[0] = myx-round(40*myscale) ; // left extreme of left arm
    result[1] = myy - round(30*myscale); // top of hat
    result[2] = myz - round(25*myscale);  // back of head
    result[3] = myx + round(myscale*max(20,40)); // max of right leg & arm
    result[4] = myy + round(120*myscale) ; // bottom of legs
    result[5] = myz + round(25*myscale);  // front of head
    return result ;
  }
        
} ```
here is my current code that extends the collision detector class

Your Avatarang's superclass is CollisionDetector.

CollisionDetector is the one that doesn't have a no-args constructor.

You need to start your constructor with super(abc). What's abc? Dunno - I don't know what CollissionDetector is.
