Please view the Fio Wiki thank you x
This is awesome can’t wait to see more also super excited for the split screen controller gaming stuff next this is really damn cool!!! Can’t wait to try the new features out
I found a BUG preventing a Spawner entity from spawning a Monster - fixed and released new version 1.2.6.1
Please read the changelog
This looks super cool going to give it a try, how good is it for building full games by chance? I had some other questions but am gonna give it a shot and play around with it. Is there a chance theres local coop/splitscreen implemented in with the scripting tools provided (this is just my favorite thing and want to add it in all my stuff)? Is it pretty extensive to use for different kinds of games and building your own systems in engine? This just looks really cool so I was just curious about some stuff!
Hi thanks for your message. Everything made cannot yet be exported but I'm working on that - in future this will be capable of exporting self-contained games.
I like your idea of split-screen and I will work to implement this
I would absolutely love the split screen idea for me it’s really important and not a lot of game engines allow for it easily this is really cool by the way I was having so much fun just messing around and building little levels last night. One suggestion with the monsters and entities it would be really cool to add your own icons in the future. Thought the monster icon was cute and thought it would be neat to change the little icons to whatever you would like. Loving it so far going to keep this saved and watch for any updates!!!!
Version 1.2.6.0 was just released with the ability to customise monster sprites in the 2D view.
* Creations can be exported to .fiopak files
* .fiopack creations can be imported and played via the File Menu
* F12 in Play Mode goes fullscreen
* PORTALS!
Split-screen coming next! changelog
Heck yeah I’m so excited to see what you do next with this engine. it’s also really awesome to have something labeled as a liminal engine it really does have that feeling. Also it’s awesome you added the ability to change that I love customizability and it adds a lot at least to me.
