Metal Slug

A C++/GTKmm implementation of metal_slug, work in progress but can be a good start for further development. Also may give u an idea about how to build simple games with GTKmm. Contain some good visual and sound materials for metal slug.

Requirement

GTKmm is required, see GTKmm Docs for detailed installation guide. I have tried on Manjaro Linux and Mac

# manjaro 
sudo pacman -S gtkmm3

# mac
brew install gtkmm3

Mac installation guide

Compile

Compile the resources first, this turns image files into c code. This speeds up the game by avoid IO at runtime and u won't get missing resource problem cuz it all comes down to a single file.

glib-compile-resources --target=resources.c --generate-source image.gresource.xml

Compile the actual game. Note that on Mac the pkg-config gtkmm-3.0 --cflags --libs command may not work in all directories. If so, run it and replace it with the output while compiling.

g++ resources.c  util.cpp GameFrame.cpp GameWindow.cpp metal_slug.cpp -o metal `pkg-config gtkmm-3.0 --cflags --libs`

U R ready to kill some zombies

./metal

TODOs

• Code clean up
• State transactions is not smooth enough
• Adding sound effect
• Implement more enemies and projectiles
• Implement explode effects
• Add more ground to the map so player and enemies can jump onto
• Find more resource for enemies, currently it's just 3 pictures.
