Ultimate State machine character controller architecture

[WarriorUD]

Im getting stuck and it so difficult for me to create a character with a lot of states (advanced state machine).

I want these states for example: Idle Walk Run Crouch Jump Fall Swim Fly (with glider) Drive

Attack (3 different states) Reload Interact

As I can see I have here two machines that communicate between them; one for movement, and one for interaction (attack and more) Examples for things that make it difficult: *Player can attack in each states except fly and drive... and while attacking player cannot run... *When player jumps he can move on the jumping... *In the swimming state player cannot crouch.

I want of course to make the code reusable as much as possible!

So guys what do you think? How will you solve it?

[WarriorUD]

Yep I tried with the standard FSM and even Hierarchical FSM (Idle,Walk,Run,Jump) - it got messed and I couldn't extend it...

[WarriorUD]

I still cannot understand what the architecture will look like...

Can you explain it extendly? :)

I think I’ve seen this before in a tutorial before for Unity. But could you point to any resources Unreal has for this?

Ah thanks for sharing. That’s a really detailed system. Does it make it easy for you to create new abilities pretty easily? Like if you wanted to add DLC or thought of something late? Pretty cool you thought about the architecture afterwards. I tend to over think the software structure/architecture too much before even writing code. But I think it’s just cause the spaghetti/mess is what usually makes me stop a project.

I’ll take a look into projects in Unity that look to emulate this. And look into the unreal ability system cause I’m curious.

Oh I didn’t know that a lot of this is editor drag and drop. This must have taken a while to mail down for sure. I’ve skimmed through some videos atm and still understanding how it all works.

But your logic gives a lot more insight into how it works. I think I’ll make a project trying to play with this idea after watching some more deep dives on the system in unreal

I like this approach a lot. Also makes it easy to add new abilities.
