hello, i was wondering if there is such a way, i can see that there are some aspects of buildbox than can do it, but health meters, fatality options or trigger options for characters? a timer? enemy AI? please someone help.
I don't think Buildbox would be the right tool for that job. If you're looking for a hobbyist type engine, Mugen is free and popular. If you're looking for something more professional, I think most of those games are built from the ground up. The most recent Mortal Kombat was built in the Unreal engine if I recall correctly. I'm not sure what Street Fighter V was done in.
If you want to make a game like mortal kombat, you should use Mugen engine, i see my friend made a game in apknite with that tool, it's a pvp game with a similar physic 2d gameplay like streetfighter
