I think that states were truly an awsome feature for gameplay coding in unrealscript.

Is there any way to create some kind of structure in c++ replacing the states of unrealscript ? What would i use ?

You can have a look at UT source code. If I remember correctly, they have C++ states for their weapon.

You can also have a look here : [State · Design Patterns Revisited · Game Programming Patterns](http://gameprogrammingpatterns.com/state.html)

They’re just Enums. You can use them for anything.

Thanks for all the information, i don’t want to write a chaotic boolean machine try code, Going for the enums for that.

There exist a design pattern that you can implement for this (and even blueprint it)

> **[State pattern](https://en.wikipedia.org/wiki/State_pattern)**

> The state pattern is a behavioral software design pattern that allows an object to alter its behavior when its internal state changes. This pattern is close to the concept of finite-state machines. The state pattern can be interpreted as a strategy pattern, which is able to switch a strategy through invocations of methods defined in the pattern's interface.

Basically You can create State class derived from a UObject, AActor or even make it a structure. Then create subclasses of the state class when you need them. Granted if your Pawn has 3 movement states then you’ll have to create 3 different C++ classes… or if you JUST implement the state in Blueprints then suddenly you are working similar to how UE3 states worked anyway.
