Allegro5_Game_Practice

Practice C and how to write a simple game in C + Allegro5.

Ideas

This project is still under early development, so please refer to this HackMD note for current thoughts and ideas. Once the draft is complete enough, I'll migrate it to this repo.

How to run?

Check Allegro5's wiki for how to install Allegro5 library on your system.

Running make (you'll need MinGW on Windows system) under repo's root directory should compile it and generate a file named play.exe. Then run this command to start the program:

./play.exe

Control

Right now we have a space-evader-like game that allows you to move you ship and fire enemies moving on the screen. However for now there's no scoring system, you're invincible (while the enemies aren't. Although they respawn again when there's no any their "friendly force" on screen). Moreover, the game never end unless you shut off the screen.

• Left/Right arrow key: Move the ship to left/right.
• Space: Fire.
• Click the exit button on screen to quit the game.

ATS2 version (prototype)

Once we've done with compiling C version, object files generated (unless you run make clean to remove all object files) can be used for compiling the version written in ATS2. Right now it's just calling the main routine under ATS2's main0 function. You can run this command to generate a file named play_ats.exe, which is essentially the same as ./play.exe generated from make utility:

patscc -cleanaft ./ats2_draft/main.dats ./bin/*.o ./bin/resource/*.o      \
  `pkg-config --cflags --libs                                             \
    allegro-5 allegro_main-5 allegro_image-5 allegro_font-5 allegro_ttf-5 \
    allegro_audio-5 allegro_acodec-5` -o play_ats.exe
