2D Random AI

[CB-TV]

I want an AI for an enemy to move through the X and Y axis in random directions. I want a certain location on the X and Y axis which they cannot go so they don’t move there. Do you know how to do this?

I put together a little simple example for you. I assumed boundaries but if you tell me more what exactly the condition is where your AI shouldn’t move anymore I could help your further. Hope it helps

//wall Boundaries
    float wall_left   = 5.0f;
    float wall_right  = Screen.width  - 5.0f;
    float wall_top    = Screen.height - 5.0f;
    float wall_bottom = 5.0f;
    		
    //AI properties
    Vector2 AI_Position;
    float Speed = 0.3f;	
    
    //Get two Random values within a Range (Screen dimensions)
    float randomX = Random.Range(0,Screen.width);
    float randomY = Random.Range(0,Screen.height);
    
    //Create a Vector2 out of the Random values
    Vector2 randomXY = new Vector2(randomX,randomY);
    
    //Get the Direction from AI to the RandomXY generated
    Vector2 Direction = randomXY - AI_Position;
    
    //Normalize the Direction to apply appropriatly
    Direction = Direction.normalized;
    
    //Check that your AI is within your boundaries
    if(	AI_Position.x > wall_left && AI_Position.x < wall_right
    	&& AI_Position.y > wall_bottom && AI_Position.y < wall_top )
    {
    //Make AI move in the Direction (adjust speed to your needs)
    	AI_Position += Direction * Speed;
    }
    else
    {
    //make your AI do something when its not within the boundaries
    //maybe generate a new direction?
    }
