Shocking truth, but significant part of Open Horizon’s code wouldn’t pass my own code review. It’s probably ok for pet-project, because if I will rewrite code every time I want, the project would be in development forever. The reason code isn’t perfect from the start is quite simple.

First of all, I don’t know how the original game worked before some research so I write first implementation, then, when problems occurs, I research again with updated information, making new assumptions. This is a continuous process, but other code is already depends on what I wrote previously so every time such problems appears I can’t just rewrite it all.

On the game mechanics side, I often choose ugly solutions right before the release, because I want it to be done already so I cut corners and struggle with my own architecture. While I’m complaining about architecture, the other aspects of the code quality, like checking ranges and pointers, are mostly fine, because it’s critical to the stability and sanity. Any unnoticed null pointer reduces game’s value to zero.

Something works already, still a lot of work to be done.

Flying in formation with ai is fun

It’s finished at some point. Of course it’s kinda useless right now, as you can’t see the result in game yet, but I wanted to release it anyway so people can make suggestions. Like, what else is required to remake AC5 missions?

You could find some documentation here. Don’t expect to have undo/redo and copy-paste in this release, it’s complicated.

You can learn on wiki page

There are a lot of tasks done in this version, like collisions, hud and special weapons, but the most important is that since this release Open Horizon finally feels like an Ace Combat game. It’s not yet feature complete, but already playable and fun.

This release also featuring experimental multiplayer, but don’t expect much – this is the first row implementation and requires a lot of additional work, so expect lags and report bugs.

There is no more requirement to run Open Horizon from ACAH folder, you can run it from other location and will be asked to specify resources path.
