ios - Is there an easy way to use decimals in calculation with SpriteKit? -


I'm new to Kit Kit and programming a program as a program to learn this.

My goal here is to get my phantom to go to the screen at random speed. This phantom is produced regularly, and it can possibly be done with maximum speed, to make the game more difficult. Should increase over time.

To do this, I am using the score, which is an integer based on time, affects the minimum duration of the movement of the phantom. The way I am trying to do this, as seen in the code below, still only produces an integer value. I would love to have more granularity than just integers. 

  int rando = (arc4random ()% 150) + 50; Int denom = _scores + 50; Float Actual Duration = Rand / Dino + 1; NSLog (@ "% F", actual component); SKAction * actionMove = [SKAction moveTo: CGPointMake (-_blimp.size.width / 2, actualY) Duration: Real Component];   
 I started using floating variables in response to Nielsbot's comments, and changed the structure of my code to show my changes, but I still get the integer value And for the decimals I was looking for. Does anyone know why this is the case?  
 Solution: Before changing them into the calculations, I changed the integer variable to float the variable. Thanks nielsbot for help!   
 
 
  float actual derivation = rand / non-nominal + 1; NSLog (@ "% F", actual component);   
 I'm not 100% confident in casting rules, but as far as I have experienced, what is this  rando  and  denom  integer and integer division is used, which results in an integer value.  
 So you have to put at least every code on  float , but using the standard  float  notation for constants, both of them Value would be better ( 1.0f ):  
  float actual quote = (float) rando / (float) denom + 1.0f; NSLog (@ "% F", actual component); Personally, I try to put all integer values ​​in float / double / CG float when used in calculation so that any of the issues of casting rule are crawled. Could

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...
