NAME extimer – Using the timer (delays and interrupts). Allegro game programming library. SYNOPSIS #include <allegro.h> Example extimer DESCRIPTION This program demonstrates how to use the timer routines. These can be a bit of a pain, because you have to be sure you lock all the memory that is used inside your interrupt handlers. The…
NAME exsyscur – Allegro game programming library. SYNOPSIS #include <allegro.h> Example exsyscur DESCRIPTION This program demonstrates the use of hardware accelerated mouse cursors. SEE ALSO END_OF_MAIN(3), SCREEN_H(3), SCREEN_W(3), allegro_error(3), allegro_init(3), allegro_message(3), clear_to_color(3), enable_hardware_cursor(3), font(3), gfx_capabilities(3), install_keyboard(3), install_mouse(3), install_timer(3), makecol(3), readkey(3), screen(3), select_mouse_cursor(3), set_gfx_mode(3), show_mouse(3), text_height(3), textprintf_centre_ex(3) Index
NAME exswitch – Controlling the console switch mode for background running. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exswitch DESCRIPTION This program shows how to control the console switching mode, and let your program run in the background. These functions don’t apply to every platform and driver, for example you can’t control the switching…
NAME exstream – Playing audio streams. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exstream DESCRIPTION This program shows how to use the audio stream functions to transfer large blocks of sample data to the sound card. In this case, the sample data is generated during runtime, and the resulting sound reminds of a car…
NAME exstars – 3d starfield and lightsourced spaceship. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exstars DESCRIPTION This program draws a 3D star field (depth-cued) and a polygon starship (controllable with the keyboard cursor keys), using the Allegro math functions. SEE ALSO BITMAP(3), END_OF_MAIN(3), MATRIX(3), PALETTE(3), SCREEN_H(3), SCREEN_W(3), allegro_error(3), allegro_init(3), allegro_message(3), apply_matrix(3), blit(3), clear_bitmap(3),…
NAME exsprite – Datafiles access and sprite animation. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exsprite DESCRIPTION This example demonstrates how to use datafiles, various sprite drawing routines and flicker-free animation. Why is the animate() routine coded in that way? As you probably know, VIDEO RAM is much slower than "normal" RAM, so it’s…
NAME exspline – Constructing smooth movement paths from spline curves. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exspline DESCRIPTION This program demonstrates the use of spline curves to create smooth paths connecting a number of node points. This can be useful for constructing realistic motion and animations. The technique is to connect the series…
NAME exshade – Gouraud shaded sprites. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exshade DESCRIPTION This program demonstrates how to draw Gouraud shaded (lit) sprites. In an apparently black screen, a planet like sprite is drawn close to the middle of the screen. In a similar way to how the first test of extrans…
NAME exscroll – Mode-X hardware scrolling and split screens. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exscroll DESCRIPTION This program demonstrates how to use hardware scrolling. The scrolling should work on anything that supports virtual screens larger than the physical screen. SEE ALSO BITMAP(3), END_OF_MAIN(3), RGB(3), SCREEN_H(3), SCREEN_W(3), acquire_bitmap(3), allegro_init(3), allegro_message(3), clear_keybuf(3), create_sub_bitmap(3), desktop_palette(3),…
NAME exscn3d – Using the 3d scene functions. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exscn3d DESCRIPTION This program demonstrates how to use scanline sorting algorithm in Allegro (create_scene, clear_scene, … functions). It also provides an example of how to use the 3D clipping function. The example consists of a flyby through a lot…
NAME exscale – Loading PCX files and bitmap stretching. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exscale DESCRIPTION This example demonstrates how to use PCX files, palettes and stretch blits. It loads a PCX file, sets its palette and does some random stretch_blits. Don’t worry – it’s VERY slowed down using vsync(). SEE ALSO…
NAME exsample – Playing digital samples. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exsample DESCRIPTION This program demonstrates how to play samples. You have to use this example from the command line to specify as first parameter a WAV or VOC sound file to play. If the file is loaded successfully, the sound will…
NAME exrgbhsv – RGB <-> HSV color space conversions. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exrgbhsv DESCRIPTION This program shows how to convert colors between the different color-space representations. The central area of the screen will display the current color. On the top left corner of the screen, three sliders allow you to…
NAME exquat – A comparison between Euler angles and quaternions. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exquat DESCRIPTION Euler angles are convenient for storing and creating 3D orientations. However, this program demonstrates that they are not good when interpolating between two different orientations. The problem is solved by using Allegro’s quaternion operations. In…
