Hi I'm trying to get my test code to work. But get the following error: Assertion failed! Program: D:\Game Assignment\Game\Release\Game.exe File: allegro-git\addons\primitives\primitives.c Line: 76 Expression: addon_initialized For information on blablablabla... This is my code: 1// C++ ALLEGRO 5 MADE EASY TUTORIAL 6 - DRAWING PRIMITIVES
2// CODINGMADEEASY

4#include<allegro5/allegro.h>
5#include<allegro5/allegro_native_dialog.h>
6#include<allegro5/allegro_primitives.h>

8#define ALLEGRO_STATICLINK
9#define ScreenWidth 800
10#define ScreenHeight 600
11
12int main()
13{
14 ALLEGRO_DISPLAY *display;
15
16 if(!al_init())
17 {
18 al_show_native_message_box(NULL, NULL, "Error", "Could not initialize Allegro 5", NULL, ALLEGRO_MESSAGEBOX_ERROR);
19 return -1;
20 }
21 display = al_create_display(ScreenWidth, ScreenHeight);
22
23 if(!display)
24 {
25 al_show_native_message_box(NULL, NULL, "Error", "Could not create Allegro 5 display", NULL, ALLEGRO_MESSAGEBOX_ERROR);
26 return -1;
27 }
28
29 // You generally want to do this after you check to see if the display was created. If the display wasn't created then there's
30 // no point in calling this function
31 al_set_new_display_flags(ALLEGRO_WINDOWED);
32 al_set_window_position(display, 200, 100);
33 al_set_window_title(display, "CodingMadeEasy");

35 ALLEGRO_COLOR electricBlue = al_map_rgb(44, 117, 255);
36

46 //al_draw_filled_rectangle(400, 400, 450, 500, al_map_rgb(255, 98, 100), 9.0);
47
48 al_draw_circle(ScreenWidth / 2, ScreenHeight / 2, 10, al_map_rgb(255, 255, 0), 3.0);
49 //al_draw_filled_circle(ScreenWidth / 2, ScreenHeight / 2, 10, al_map_rgb(255, 255, 0), 3.0);
50
51 al_draw_ellipse(ScreenWidth / 2, ScreenHeight - 100, 10, 5, al_map_rgb(255, 0, 255), 4.0);
52 //al_draw_filled_ellipse(ScreenWidth / 2, ScreenHeight - 100, 10, 5, al_map_rgb(255, 0, 255), 4.0);
53
54 al_draw_arc(10, ScreenHeight - 100, 10, 0, 4.0, al_map_rgb(255, 0, 0), 2.0);

56 al_draw_line(100, 500, 300, 500, electricBlue, 6.0);

59
60 al_draw_spline(points, electricBlue, 1.0);
61
62 al_flip_display();
63 al_rest(5.0);
64 al_destroy_display(display);
65
66 return 0;
67}
Does anyone know how to solve this?:-/ EDIT i just google some more. After a while i found that i have to call al_init_primitives_addon. So i added this code just to check if it's there. 1if(!al_init_primitives_addon())
2 {
3 al_show_native_message_box(NULL, NULL, "Error", "shit just got real", NULL, ALLEGRO_MESSAGEBOX_ERROR);
4 return -1;
5 }
So helpfull when they dont put this in the tutorials.... |

Yes you require a call to al_init_primitives_addon() before using primitives drawing operations.
