Hey! Great tutorial! Just want to post my solutions for the two problems i can see in your system. 1) The room overlapping Put this check in the TryGenerateRoomFunction : if (_roomGrid[x, y] != 0) return false; 2)The error when a room tries to be created outside of the grid Put this check also in the TryGenerateRoom function (put it before all the other checks by the way) : if (x >= gridSizeX || y >= gridSizeY || x < 0 || y < 0) return false; Hope this helps anyone!

when you fix the overlapping the first room never spawns with any doors

Great video, please continue! Adding a few timestamps/chapters to videos as long as this one could be nice, just a thought. But good job, mate!

Everything works just fine! Great tutorial! I'd like to see you explain how to spawn a boss room, a shop, secret rooms, like in Isaac!

I'm glad you liked it! I might do that in the future!

@picatsso6721 6 ай бұрын

Oh, by the way, I just did it myself, with help of ChatGPT, now it's perfect: Boss Room is always has a connection to only one room and is always the furthest room from the start, also Treasure room and Shop room generating with only one room adjacent to them. It is still based on your code, just saying, if you are interested to see how AI implemented this - let me know.@@rootbindev

This tutorial is great, well done and keep it up! I did notice that some of the rooms do overlap on top of each other during runtime. Do you know why?

@rootbindev 8 ай бұрын

Did you follow the tutorial 100%? In my game, using this code I get no overlaps

@ItsReece2 8 ай бұрын

Yes, I did follow it but might be possible I missed something in the tutorial. I must say it's very uncommon it happens the overlap; normally overlaps from starting room and occasionally another room from the neighbouring nodes. @@rootbindev

I also noticed this same issue. It is pretty far and few between, and also as Reece mentioned it is usually an overlap on top of the starting room. Rarer occasions do include non-starting rooms overlapping too. I'm not sure if this is the most efficient fix, but in our Update when we call the TryGenerateRoom 4 time, I added checks for neighbors prior to actually generating in any direction. I have not seen any overlap since I added these checks. if (gridX > 0 && roomGrid[gridX - 1, gridY] == 0) { //No neighbor to the left TryGenerateRoom(new Vector2Int(gridX - 1, gridY)); } if (gridX < gridSizeX - 1 && roomGrid[gridX + 1, gridY] == 0) { //No neighbor to the right TryGenerateRoom(new Vector2Int(gridX + 1, gridY)); } if (gridY > 0 && roomGrid[gridX, gridY - 1] == 0) { //No neighbor below TryGenerateRoom(new Vector2Int(gridX, gridY - 1)); } if (gridY < gridSizeY - 1 && roomGrid[gridX, gridY + 1] == 0) { //No neighbor above TryGenerateRoom(new Vector2Int(gridX, gridY + 1)); } @@rootbindev

@@rootbindev I have the same problem, and you can see the problem in your video too (eg, 20:07). You can see 17 room created, but only "12" visible

Try adding the checks that @FennrirWolf posted above@@bsdrago

The camera in mine is square instead of rectangle but all of the settings are the same as what you have in the Inspector. What might need to be changed? edit: Found a solution: "By default, cameras will match the shape of your view in the Game window. To set it to the aspect ratio you want, go to the upper-left corner of the Game window, click "free aspect" and change it to the aspect ratio or resolution you want" In our case, I think it's 16:9

Great tutorial, how would I go about instantiating something at the last room generated... Edit: Figured it out. Add this code where you set generationComplete = true. GameObject lastRoom = roomObjects.Last(); Instantiate(boss, lastRoom.transform.position, Quaternion.identity); Make sure your script is using System.Linq;

How would the code change if we were to want the walls of adjacent rooms to be the same wall rather than having space in between the rooms?

@bixarrio5251 7 күн бұрын

Change roomWidth to 17 and roomHeight to 9. The grid cells will then be the exact size of the room and the walls will lie on top of each other to make it look like they're the same wall
