This problem however could also be extended to things such as snake, or some other simple AIs. To learn more, see our tips on writing great answers. let's take another example. Up - Not available, since the last move was down (reversing itself) Right - Not available, since there is a wall directly to the right Down - Available Left - Available From here we can see that should it move down, then the same availability will occur. I don't know how many versions of it I have. I also was aiming entirely for speed, which this achieved. (The containing block is the ancestor to which the element is relatively positioned.) Once we have a nice EnumSet to use, then we can either create an array of it and grab a random item from the array, or we can use the iterator of it to iterate over random.nextInt(size) items (not the cleanest and fastest solution perhaps, but it should be faster than creating an array).

I think that you can simplify the simulation like this without losing any clarity: I've changed the terminology from right/left to east/west, since the former could be misinterpreted as a relative turn rather than an absolute heading. Use Unity to build high-quality 3D and 2D games, deploy them across mobile, desktop, VR/AR, consoles or the Web, and connect with loyal and enthusiastic players and customers. forefinger is to the left, but this time make sure the for magnetic field is B. the previous argument in your original code for nextDirection(): What the final Stream.of() statement does is this: This solution can't claim to be the speediest, and I still think Simon's answer provides the ideal balance between performance and an 'OO'-approach. Thanks for contributing an answer to Stack Overflow! Due to this and what Knuth once said, I went for readability. Since the map consists of tunnel and wall cells, we could describe it as zeros and ones in a two-dimensional array like the following: Since every cell is in a two-dimensional array, we can access its value by knowing its row and column such as map [row][column]. of the magnetic field, the whole current again will reverse. You can see the complete algorithm in the following snippet: Congratulations for reading through this tutorial. The first part of the condition also consists of two conditions. The first value, UP, corresponds to 0, DOWN is 1, and so forth. The use of a dict is not ideal. Answers and Comments, transform.position.x ?

If it should move left: up, left and down These can be changed to whatever value needed. To avoid the complexity of diagonal turns, the algorithm needs to specify the horizontal and vertical directions. You need code like this: The simplest way to do this is to simply do a modulos of the rand function to get a numbers between 0 and 3(inclusive). The random walk can be easily implemented in Python.
