How do I make a object make a random path?

I have a grid of 16 rooms, that are like in a 4x4 square. I want to make a random path between them, like from one room of the top line of rooms (the entrance) to one room in the bottom line of rooms(the exit). But I want the path to not go through the same room twice. For you to understand better I leave here a video where they explain this method (is from the Spelunky game) youtu.be/Uqk5Zf0tw3o

May not be the most optimized code, but it works.

Thanks very much!!!!!!! I will apply it to my code soon and if I finish the game I will sure give you credit.

But can I ask you another favour? I think is too much so if you don't want to do itis ok, could you make also the map creation like in Spelunky, or if it's too much just explain to me how to make 16 tilemaps and design the rooms like in the video, but thanks for what you have just created. <img src="{SMILIES_PATH}/icon_e_wink.gif" alt=";)" title="Wink" />

(I downloaded them from some old post, which unfortunately I can't find now)

This example may look different from what you need, but it basically does the same task - connects occupied tiles on the tilemap to each other.

So if you have two tiles, one at (0,0) and another at (0,1), you need for the first one to select the tile with exit on the bottom, and for the second tile - with entrance on the top. And so on..

You can do all this with an array instead of the tilemap.

I was looking at the .capx and I wanted to know if the grid can be made bigger or smaller. I tried increasing its size but the random path still restricts itself to the 4x4 grid space. Also, can you give an example at how you would apply this to a game? I'm trying to think about how it would work in a platformer.

YoHoho

Of course you can change it for a bigger grid, just need to modify the values throughout the code - for example for 10x10 grid in event #2 change condition to newX<10, in event #4 change the formula to min(9, x+1) etc.

Did you watch the video from the first comment? This algorithm is used for dungeon generation.

Reupload the fonts capx plz.

What "font capx"?
