java - Collision Response of ball at Corners of rectangle -


I have a fixed rectangle when the ball is at the top of a triangle, I have a tangent (rectangular peak) at the point of contact Let's count. Then I match the tangent to rotate the velocity wheel, flip the y value of velocity and turn it back. Here is my code for the top-left corner: 

  double c1x = rec.x-ball.getX (); Double c1y = rec-ball.getY (); If (C1 * C1 + C2 * C2 and Lt; Ball.Getrediais) * Ball.Getrediais ()) {Double Angle = Monastery.T.T 2 (-C1X, C1A); Angle angle created by tangent vector 2D v = ball.velocity.rotate (angle); // Rotate the velocity vector by 'Wayne', if (v.y & lt; 0.0f) // ball is already getting away from corner returns; v.setY (-v.y); // flip y ball.vivecty = v.rotate (-gangle); // Return to turn back; }   
 But this code does not work when the ball is attacked in the corner, it gets trapped, moves on the top edge and then falls, does not bounce back. Am I correcting it?   
 
 
 By making some assumptions about your conventions, I suggest:  
  Double Angle = Math Stenosis 2 (-C1x, -C1);   
 If that does not work, we can do some experiment to know what's really going on.  
  Edit:   
 Okay, we should raise this with simple solutions. Try these experiments:  
 1) Set (0,1) and confirm that the ball runs straight after the collision.  
 2) Set the Velocity (-1,1) and verify that the ball goes up and down.  
 If those tasks are expected, choose a path that you would expect to behave in a normal way, such as rising up and down on the left side, but slightly left, then your Run it through the code  but print all the values ​​in the collision  and let us know what they are. This is at the beginning of the values ​​of at least  c1x ,  c1y ,  angle , and  velocity [/ code] and after each rotation . Perhaps notice where screams are, and if you will not.

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...

java - JPA TypedQuery: Parameter value element did not match expected type -

I am using JPA 2.0 and getting the following code in the DAO layer: Public Zero Test () {string key = "status"; String [] Conditions = {"A", "B"}; & Lt; TestTable & gt; Results = Search (Keys, Conditions); } Public listing & lt; TestTable & gt; Search (string key, object value error) {string sql = "test ndf to testlet and jade nand." + Key + "in:" + key; TypedQuery & LT; TestTable & gt; Query = entityManager.createQuery (SQL, TestTable.class); Query.setParameter (key, Arrays.asList (valueArr)) / *** Error Line *** Return query.getResultList (); } In the above error line, it throws the following exception: java.lang.IllegalArgumentException: parameter value element [[Ljava.lang.String; @ cbe5bc] did not match the expected type [java.lang.String] Why is this expected type string while actually this string []?

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...
