Following a tutorial and getting this error: Am i missing something or is the compiler taking the piss? code for the header and .cpp here: 1#pragma once
2
3#include <allegro5\allegro.h>
4#include <allegro5\allegro_font.h>
5#include <allegro5\allegro_ttf.h>
6
7#include "GameScreen.h"
8#include "SplashScreen.h"
9#include "TitleScreen.h"
10
11class ScreenManager
12{
13private:
14 ScreenManager();
15 ScreenManager(ScreenManager const&);
16 void operator=(ScreenManager const&);
17
18 GameScreen *currentScreen, *newScreen;
19public:
20 static ScreenManager &GetInstance();
21 ~ScreenManager(void);
22
23 void AddScreen(GameScreen *screen);
24
25 void LoadContent();
26 void UnloadContent();
27 void Update(ALLEGRO_EVENT ev);
28 void Draw(ALLEGRO_DISPLAY *display);
29 void Initialize();
30
31};
.cpp: 1#include "ScreenManager.h"
2
3ScreenManager &ScreenManager::GetInstance()
4{
5 static ScreenManager instance;
6 return instance;
7}
8
9ScreenManager::ScreenManager()
10{
11}
12
13ScreenManager::~ScreenManager()
14{
15}
16
17void ScreenManager::AddScreen(GameScreen *screen)
18{
19 newScreen = screen;
20 currentScreen->UnloadContent();
21 currentScreen = newScreen;
22 currentScreen->LoadContent();
23}
24
25void ScreenManager::Initialize()
26{
27 currentScreen = new SplashScreen();
28}
29
30void ScreenManager::LoadContent()
31{
32 currentScreen->LoadContent();
33}
34
35void ScreenManager::Update(ALLEGRO_EVENT ev)
36{
37 currentScreen->Update(ev);
38}
39
40void ScreenManager::Draw(ALLEGRO_DISPLAY *display)
41{
42 currentScreen->Draw(display);
43}
If u need any other code ill supply, ive tried to figure this out and its racking my brain ... edit: 1InputManager input;
2 ScreenManager::GetInstance().Initialize();
3 ScreenManager::GetInstance().LoadContent();
4 //----------------
5 al_start_timer(timerFPS);
6 while(running)
7 {
8 ALLEGRO_EVENT events;
9 al_wait_for_event(event_queue, &events);
10
11 if(events.type == ALLEGRO_EVENT_DISPLAY_CLOSE)
12 {
13 running = false;
14 }
15 if(input.IsKeyPressed(events, ALLEGRO_KEY_ESCAPE))
16 running = false;
17 if(events.type == ALLEGRO_EVENT_TIMER)
18 {
19 al_get_keyboard_state(&keyState);
20 ScreenManager.GetInstance().Update(events);
21 redraw = true;
22 }
23
24 if(redraw && al_event_queue_is_empty(event_queue))
25 {
26 ScreenManager.GetInstance().Draw(display);
27 al_flip_display();
28 al_clear_to_color(al_map_rgb(0,0,0));
29 }
30 }

The error is somewhere in main.cpp. The code you provided is not relevant As per your edit, to access a static class method or variable you do this: Foo::Bar() Not: Foo.Bar() In some places, you access the ScreenManager::GetInstance the latter way. You need to do it the former. --- |

It looks to me like it's complaining about syntax on line 65 (possible a line or three before 65) in main.cpp. Post that. They all watch too much MSNBC... they get ideas. |

It won't compile without all those header files, but ScreenManager.GetInstance().Update(events); on line 65 looks suspicious to me (Disclaimer: I don't do C++) Should it be ScreenManager(GetInstance(Update(events))); ? They all watch too much MSNBC... they get ideas. |

Thanks Arthur but im calling a static function so therefore i cannot do anything but ScreenManager::GetInstance().Update(); etc.. Thanks anyways |
