Network / Quick question about the SFML Netowrking tutorials

« on: January 11, 2012, 04:53:22 am »

I am attempting to make my game a multiplayer game but know diddly-sqwat about network programming.  Are the tutorials provided on this site in-depth enough for me to adequately learn and apply the skills necessary to do what I want? Or should I buy a C++ Network Programming book.

Graphics / Sprite Movement on Single MouseClick

« on: January 02, 2012, 12:55:32 am »

Hello.  I was wondering if anyone had any suggestions as how to go about making a sprite move from Point A to Point B on a 2d plane.  I am able to do this, but the sprite simply warps from one point to another...I have looked into making a speed variable (dont want to use framerates because of the "faster on faster computer" thing) somehow.  I have also looked into vectors some, but have not been able to figure out how to set the sprite's position with the vector.

EDIT: Using SFML 1.6

Maybe some code will help too

Code: [Select]

if (App.GetInput().IsMouseButtonDown(sf::Mouse::Left)) {

            OldX = PlayerObj.GetPosition().x;
            OldY = PlayerObj.GetPosition().y;
            NewX = App.GetInput().GetMouseX();
            NewY = App.GetInput().GetMouseY();
            XVector = (OldX - NewX);
            YVector = (OldY - OldY);
        }
        //Vector...
        float OldPosition = ???;
        float NewPosition = ???;
        sf::Vector2f GetDir(sf::Vector2f OldPosition);
        sf::Vector2f RVector = NewPosition - OldPosition;
        float temp =(float) sqrt((RVector.x * RVector.x + RVector.y * RVector.y));
        RVector = RVector / temp;
        RVector = RVector * SPEED;
        //Set position...
        PlayerObj.SetPosition(RVector.x, RVector.y);

General / Storing and recalling variables within an event

« on: December 30, 2011, 04:59:16 am »

So I am trying to make an application that requires multiple values to be considered.  When EventA happens, I want Variable1 to be a certain X number.  Then, if statements can check to see if X is the number for that certain if statement, and carry on with a specific order.  I am not aware of how to do this exactly, so I tried to do it with strings:

Code: [Select]


#include <SFML/Graphics.hpp>

 int main()
 {
     // Create the main window
     sf::RenderWindow App(sf::VideoMode(800, 600), "Test");

     sf::String Value1("1");

     sf::String Text1("Value1 is active");
     Text1.SetPosition(100.f, 100.f);

     // Start the game loop
     while (App.IsOpened())
     {
         // Process events
         sf::Event Event;
         while (App.GetEvent(Event))
         {
             // Close window : exit
             if (Event.Type == sf::Event::Closed)
                 App.Close();

             if (App.GetInput().IsKeyDown(sf::Key::Up))   Value1.SetText("2")

             if (Value1.GetText() == "1")   Text1.SetText("Value1 is active");
             if (Value1.GetText() == "2")   Text1.SetText("Value1 is inactive");
         }

         // Clear screen
         App.Clear();

         // Draw the string
         App.Draw(Text1);

         // Update the window
         App.Display();
     }

     return EXIT_SUCCESS;
 }

It doesnt work though.  Any suggestions? Sorry if I havent been clear, I am not sure how to express what I want to do  :cry:
