    Hello,

    I 'm making a game in c #, I have the character and enemy classes and I would implement the State pattern to the class enemy.

    The state of enemies are:
    -sleep
    -walk
    -ofensive

    Initially it would be asleep and when the player approached a little the state change to Walk, and get even more change to Offensive .

    I have seen many examples but I dont understand , too complex for me or i cant apply to my code.

    As I have understood the patron state maybe would have these classe :
    Enemy.cs
    State.cs
    StateSleep.cs
    StateWalk.cs
    StateOffensive.cs

    Can someone help me with the structure code? And how to call the states?


    Thanks!

    There's nothing special about it. Put 3 scripts on your object. When some trigger event happens, disable the working script and enable the transition to script.

    Well that certainly simplifies a lot of my FSMs. Silently cursing myself as an idiot at the moment. Going to attempt this pattern for simple FSMs in future.
