I did right? its a const? how can i properly fix it? because if i call const View& view it will give me an error.

Thanks your solution worked!

May have another question but its kinda different subject:

i have declared a function called ResizingView but when i use the function in my main it wont recognize the view input.

how can i fix this?

The code looks as followed:

#include "stdafx.h"
#include <SFML\Graphics.hpp>
#include <iostream>
#include "Player.h"
#include "Platform.h"

using namespace sf;
using namespace std;

static const float VIEW_HEIGHT = 200.0f;


/* resize view*/
void ResizingView(const sf::RenderWindow& window, sf::View& view)               <---------- DECLARE VIEW
{
   float aspectRatio = float(window.getSize().x) / float(window.getSize().y);
   view.setSize(VIEW_HEIGHT* aspectRatio, VIEW_HEIGHT);
}


int main()
{
   RenderWindow window(VideoMode(600,600), "Kollhodt The Game", Style::Close | Style::Titlebar | Style::Resize);
   View view1(Vector2f(0.0f, 0.0f), Vector2f(VIEW_HEIGHT, VIEW_HEIGHT));
   
   Texture playerTexture;
   playerTexture.loadFromFile("baldricfrontwalksheet_01.png");
   
   Player player(&playerTexture, Vector2u(9, 4), 0.1f, 60.0f);
   Texture platformTexture;
   platformTexture.loadFromFile("MakingMap2.png");

   Platform platform1(&platformTexture, Vector2f(20.0f, 1200.0f), Vector2f(200.0f, 230.0f));

   float deltaTime = 0.0f;
   Clock clock;
   
   while (window.isOpen())
   {
      deltaTime = clock.restart().asSeconds();

      Event evnt;
      while (window.pollEvent(evnt))
      {
         switch (evnt.type)
         {
         case Event::Closed:
            window.close();
            break;
         case Event::Resized:
            ResizingView(window, view);               <------- IT WONT RECOGNIZE VIEW
            break;

         }
      }

      

   
      player.Update(deltaTime);
      
      platform1.GetCollider().CheckCollider(player.GetCollider(), 0.0f);

      view1.setCenter(platform1.GetPositionPlatform());
      /*
      view2.setCenter(player.GetPosition2());
      */

      window.clear();

      window.setView(view1);
      /*
      window.setView(view2)
      */
      

      player.Draw(window);
      platform1.Draw(window);
      window.display();

      
      
   }
   
   
   return 0;
}

moving the player refers to moving sf::RectangleShape.

Im showing all the code i have :/

when the sf::RectangleShape is 'idle' the animation runs normal speed, but when i move the sf::RectangleShape  it speeds up super fast.

Another question:

How comes my  sf::RectangleShape only moves when i move my mouse. When i press D or A (while not touching the mouse) the  sf::RectangleShape wont move. When im moving my mouse around on the program ( without clicking annything) and then press A or D the  sf::RectangleShape moves.

Animation(Texture* texture, Vector2u imageCount, float switchTime);

I didn't check, but it looks so obvious that it is switchTime

But how can i alter it correctly?

if i change the switchTime from 0.1 to something else and run the program, it wil first run slower but after moving the player (with w,a,d or s) it will start to run fast again.

Hi guys! i'm very new to C++ and trying to set up a walk animation but when i run the program my animation is way to fast.

I'm currently following a tutorial how to make an animation, but i dont know how to alter the speed. The maker of the tutorial is not responding to my questions so thats why i'm here

Can you guys help me find the right alteration to my code to make my animation slow down?

My code looks like this:

main.ccp:

int main()
{
        RenderWindow window(VideoMode(600, 400), "first window made in C++", Style::Close | Style::Titlebar | Style::Resize);
       
        RectangleShape player1(Vector2f(50.0f, 50.0f));
        player1.setPosition(150.0f, 300.0f);
        Texture playerTexture;
        playerTexture.loadFromFile("baldricfrontwalksheet_01.png");
        player1.setTexture(&playerTexture);

        Animation animation(&playerTexture, Vector2u(9, 4), 0.3f);

        float deltaTime = 0.0f;
        Clock clock;
       
        while(window.isOpen())
        {
                Event evnt;
                while (window.pollEvent(evnt))
                {
                        deltaTime = clock.restart().asSeconds();

                        switch (evnt.type)
                        {
                        case Event::Closed:
                                window.close();
                                break;

                        case Event::Resized:
                                printf("New window width: %i New window height %i", evnt.size.width, evnt.size.height);
                                break;

                                // Input possible
                        case Event::TextEntered:

                                if (evnt.text.unicode < 128)
                                {
                                        printf("%c", evnt.text.unicode);
                                }

                        }

                        if (evnt.type == evnt.Closed)
                        {
                                window.close();
                        }


                }
                /* Player1 movement */
                if (Keyboard::isKeyPressed(Keyboard::Key::A))
                {
                        player1.move(-0.1f, 0.0f);
                }

                if (Keyboard::isKeyPressed(Keyboard::Key::D))
                {
                        player1.move(0.1f, 0.0f);
                }

                if (Keyboard::isKeyPressed(Keyboard::Key::W))
                {
                        player1.move(0.0f, -0.1f);
                }

                if (Keyboard::isKeyPressed(Keyboard::Key::S))
                {
                        player1.move(0.0f, 0.1f);
                }

                }
                */

                animation.Update(3, deltaTime);
                player1.setTextureRect(animation.uvRect);
                window.clear();
                window.draw(player1);
                /*window.draw(player2);*/
                window.display();
        }
       
    return 0;
}
