What's the name of the concept of scripting in a Sim/RTS type of game?

[Ñuño Martínez]

I've downloaded your code and

sudo apt install liballegro5

but for some reason it's not able to initialise the allegro stuff.

Any hints on how to debug it?

Cheers,
Gus

You need to install the dev versions too (liballegro5-dev) as well as the addons. Also see what SilverWarrior said.

Note that Momen3D use an old Allegro version (5.0, not 5.2).
