2D Random AI
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?
Have you tried something already? Random numbers can be generated by Random.Range(). Why don't you post what you think should work?
I have a script like this: but I don't know how to make it go in other directions, then stop at a certain location.
void Update () {
print (walkingDirection);
walkAmount.x = walkingDirection * walkSpeed * Time.deltaTime;
if (walkingDirection > 0.0f && transform.position.x >= wallRight)
walkingDirection = -1.0f;
else if (walkingDirection < 0.0f && transform.position.x <= wallLeft)
walkingDirection = 1.0f;
transform.Translate(walkAmount);
}
}

Your guy will go left, right, ahead, after you and others.
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?
}

I'm not used to C#. What are the errors?
Where are you putting the code? Try Declaring the variables inside the class and set the variables inside a function of that class.
Yeah, I did that. But I don't really know C#. Could you possible show me what to do because I've put everything in a class but I don't know what else to do?
Were you ever shown what to do? I would like to get the script posted above to work too....If anyone can help, please post. Thank you.
