java - Paddle game - Ball contacting paddle -


Currently coding Java games where the sword has three walls and one paddle, trying to implement the collision method Checks the ball attacking the paddle Ball sometimes notice the pedal, and sometimes it does not, it does not. If someone tells me where I am wrong

My code: 

  Public boolean is Sieigenie (ball one ball) {int ballYPos = aBall.getY (); // getY will return the end of the ball paddleXPos = Paddle.this.getX (); / / Will return to the upper left corner of the pedal if (ballypos-aBall.getRadius () == Paddlex POS + width) // Check for yPos-radius {return true; } And false return; }    
 
 
 You are currently checking whether they are exact identical. So it will be right only when they are exactly the same, i.e. 10.1 == 10.1 .... However 10.1! Try to use <10p  
  
  if (ballYPos-aBall.getRadius () & lt; = paddleXPos + width) // YPos- Check for radius {Back to true; }   
 However it seems that this is a clunk way to calculate in any way. You're comparing the Y value of the ball in the pedal X value.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
