c# - (XNA) Velocity doesnt reach 0 -


I recently started working with XNA and there is a little problem. I have a phantom that is completely fine and everything runs, but velocity does not reach 0. It's always 2.5 or -2.5 or something like that. 

  Protected Override Zero Update (GameTime GameTime) {// Control (if Keyboard GateState). ICaiddown (Keys.) {If (well.x  maxVel * (- 1)) vel.X - = acc.X * 3 * (float) game time.Apple group gametime TotalSeconds; Player. SpritePos.X + = vel.X * (float) game time. AspenGametime Kolshakand; } And if (vel.X! = 0) {// Velocity should be set to 0, if no button is pressed. It does not work // it just stops at 2.5 or -2.5, so that no button is pressed, the speed of the connírent is slowed. If (vel.X> 0) {player.spritePos.X + = vel.x * (float) game time.appalgroup timeshundred; Vel.x - = acc.X * (float) game time. AspenGametime Kolshakand; } If (vel.X <0) {player.spritePos.X + = vel.x * (float) game time. ElapsedGameTime TotalSeconds; Vel.x + = acc.X * (float) game time. Applegate Scheduling Clause; }} // Collision with Screen Boundary (Player.pritPos.X + player.spriteTextxture.Width> GraphicsDisvision.Visport.Width || Player.pritPos.X   
 As I said, I'm new to coding with C # / XNA, so this code is very impure.   
 
 
 The reason this part is:  
  if (vel.x & Gt; 0) {player.pritPos.X + = vel.x * (float) game time. ElapsedGameTimeCollus; Vel.x - = acc.X * (float) game time. AspenGametime Kolshakand; } If (vel.X <0) {player.spritePos.X + = vel.x * (float) game time. ElapsedGameTime TotalSeconds; Vel.x + = acc.X * (float) game time. Applegate Scheduling Clause; }   
 If I rewrite it using the value of acc.X provided by you and I'm guessing gametime. Time has expiredThere is a second running on the total turnover of 1/30 and XANA 30 updates:  
  if (vel.X> gt; 0) {vel.x - = 150 * (float) 1/30; } If (vel.X <0) {vel.x + = 150 * (float) 1/30; }   
 Which is:  
  if (vel.X> 0) {vel.x - = 5; } If (vel.X <0) {vel.X + = 5; }   
 So if vel.X is 2.5, then it will reduce it to -2.5. In the next update it is -2.5, so it grows to 2.5, and it keeps switching between the two but it never gets 0 to do this.  
 To fix this, you can try:  
  if (vel.X> 0) {player.spritePos.X + = vel.x * ( Name) gameTime.ElapsedGameTime TotalSeconds; Vel.x - = acc.X * (float) game time. AspenGametime Kolshakand; If (vel.X <0) vel.x = 0; } If (vel.X <0) {player.spritePos.X + = vel.x * (float) game time. ElapsedGameTime TotalSeconds; Vel.x + = acc.X * (float) game time. Applegate Scheduling Clause; If (vel.X> 0) vel.x = 0; }

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...
