TurtleAI
By Shadow

Wanderer AI
Essentially this is and I quote 'a blind & drunk' turtle AI. It is my first AI so, it is very simple. It just picks a random direction and goes in it.

Pathfinder AI
This a somewhat a more advanced AI than the Wanderer. When it detects a wall, it either turns left or right. The constant 1 direction bug in the video is fixed.

Pathfinder goin through a maze:

Pathfinder II
I made a much better version of the pathfinder, coded from scratch, it requires Techzune's TurtleAPI found here: http://www.computerc...zunes-programs/
When it gets to a wall, it checks left and right and then goes either left if right has a block, right if left has a block, and if both sides have a block, it turns around. Also, this is my first proper AI.

Added a video with a Pathfinder going through a maze.

[bonnis]

good program(very nice!)
you should add the code to the topic />

[Xtansia]

This isn't AI,
Artificial Intelligence means that it makes decisions based on its surroundings(Similar to how a human or animal does) which this does not this just chooses a random direction when it hits a wall.

[ficolas]

Yes isnt an AI, but is a start, I will use this for a program called turtlet (turtle pet) but changing some thins

[Wojowu]

You can make turtle stop when finding exit. Just add

while turtle.detectDown()==true then <your program> end

If you destroy block on floor on exit program will stop, and after that something can be printed.

This is in very early development, don't expect an update for a few days though, I have school :/

[Mendax]

UPDATE on new AI: It will require Techzune's TurtleAPI
Found here: http://www.computerc...zunes-programs/
It is not here yet though.

Pathfinder II Added, video coming after school. Don't forget to get Techzune's TurtleAPI: http://www.computerc...zunes-programs/

How about:

Spoiler

while true do
turtle.turnRight()
if turtle.detect() == true then
  turtle.turnLeft()
  if turtle.detect() == false then
    turtle.forward()
  else
    turtle.turnLeft()
    if turtle.detect() == false then
	  turtle.forward()
    end
  end
else
  turtle.forward()
end
if turtle.detectDown() == false then  --If it hasn't got a block under it anymore, it has reached the exit and stops.
  break
end
sleep(0.1)
end

That uses the 'keep your right hand always on the right wall'-technique. So if it can go right, it will, if it can't, it'll check for going forward and if that is not possible it'll try going left.

This way the bot always comes to the exit, no matter how complicated the maze. (Note, the paths must be 1 wide and the exit must be marked with the absence of a block under the bot.)

This is still a 'dumb'-ai. The real challenge would be mapping the entire maze by walking trough it and then determining the best path. I believe Cruor is trying to achieve that.

Yes, but the idea is not to remove a block. So... yeah...

What do you mean? This doesn't remove blocks?

No, It's not supposed to. Also, I fixed the always go left in my AI, These AIs were not made for the one purpose of going through mazes Dx

I still don't get it, where in this code does it remove a block?

Code:

while true do
turtle.turnRight()
if turtle.detect() == true then
  turtle.turnLeft()
  if turtle.detect() == false then
		turtle.forward()
  else
		turtle.turnLeft()
		if turtle.detect() == false then
		  turtle.forward()
		end
  end
else
  turtle.forward()
end
if turtle.detectDown() == false then  --If it hasn't got a block under it anymore, it has reached the exit and stops.
  break
end
sleep(0.1)
end

it only detects blocks, and if there is none, it'll move forward (since there is no block, thus a path).
Also , the part where it detects down, this is to check if it's at the finish, it doesn't break the block underneath it, it breaks the loop.

break

is for breaking a loop, like here it breaks the

while true do
end

loop, otherwise it would continue forever.

turtle.dig()

is for breaking blocks />

I said it before, this is not for just going through mazes, I like doing other stuff with it.
