Very useful, thanks for sharing! Random worlds is typically what I want to create. Sadly it's a lot more complicated when you want either a platformer or RPG world that uses tilesets and has complex terrains being randomly generated, still haven't found a good method for that.

[@GDevelopApp]

Yeah, that's definitely a lot more complicated than what's in this video. 😅 I'm personally a fan of semi-random generation. Similar to the binding of isaac, spelunky, and I think rogue legacy works that way too. Where hand crafted chunks/rooms are placed randomly throughout the game on a grid. It's a "curated" randomness. Maybe that helps in some way. 👍 -Wesley

[@CardboardGiraffe]

​@@GDevelopApp hey Wesley i just want to make a Tamagotchi/Digimon type thing. Could you suggest any resources? TIA

[@GDevelopApp]

@@CardboardGiraffe I'm not sure if there are any tutorial videos specifically about that, but on this channel there are videos on enemy AI and changing state based on their animation. So you might be able to learn some things from the enemy AI videos. And you'll probably need a lot of buttons to interact with, so the video on simple menu UI would be good to watch too. 🤔 Hope that helps. 👍 -Wesley

Question: How do you ensure that if you in a circle, starting at a 4-way room, that, say, when you get to directly above the 4-way, there will even be a doorway generated on your side at all so you are even able to go down, back into the 4-way, at all?

@@GDevelopApp Wesley, I just tried adding corners and crossroads to the BoI room generation and it's broke lmao

@@noface7842 Try tweaking the number that's picking them, like in the example I made. The 4 way room layout has a lower chance of spawning, because if it was a 33% chance it would create way too many overlapping rooms. 🤔 -Wesley

[@TheWizardsTales]

I've been working on this type of thing for a while, but I keep running into the issue with doors leading to rooms that have already been generated from a different direction that don't have a return door. I didn't notice anything in this tutorial that would FIX that issue, but it also doesn't look like you ran into it either. I thought maybe making it generate a secret door, which I'm working on right now, but that makes things even more complicated. I have to make each individual section of wall out of sprite objects, and if the player enters through the open door into a room that doesn't have a door, it generates a "secret door" sprite in the wall. Since that works differently than the way the rest of the game normally works, it will need its own set of interactions, similar to stairs. Wish me luck, I'm not sure if this is going to work as intended!

[@GDevelopApp]

In this version the generation resets if a room spawns on top of a room and tries again. So this version does run in to that issue, but if it happens it'll just stop and retry on the next frame. There's a link at the bottom of this video's description that leads to a video made by one of the original creators of the binding of Isaac and how their level generation worked. That's what I based this version off of. 👍 -Wesley

[@TheWizardsTales]

​@@GDevelopApp Oh, I get it! I didn't even think about that because the one I've been working on generates the rooms in batches, which sometimes leads to rooms that have already been generated that don't have return doors. Argh, that kinda messes things up. I'm making a mystery game where the mystery is getting generated dynamically as you go, and it needs to remember things like if you've already been in a kitchen so it doesn't generate a second one. Maybe I should just rework it so it starts by generating the whole map using this method and then building the mystery from there. I'm used to working in C#, but my laptop won't run Unity so I've had to switch to GDevelop. It is a great tool, and fast, but I'm having a hard time figuring out how to do everything I want to do with visual scripting.

[@Ward8261]

I have a question Can this be used to help make random world generation like minecraft Because i'm getting the art set up But I can't find anything about random Is generating bioms or objects

[@FuzzyFallout]

Is their a way to after a certain amount of randomly generated rooms to create a custom room like a boss room?

[@GDevelopApp]

Definitely. You could put all of the dead end room objects in to a group, then after the level is generated use the "pick random object" condition to pick 1 from that group, and create the boss in that room. Or change the room in some way to make it a boss room. But either way, "pick" one of the dead end rooms and create the boss in it. 👍 Hope that helps. 👍 -Wesley

[@haon6945]

Can you use procedural generation on x and y for the first one?

[@noimagination9326]

Pls help....1:00 Where & how did u create this group called "AllObjects"?

[@GDevelopApp]

The groups panel. It's one of the panels on the top right. Create a group with that panel, and then add whatever you need in to the group. 👍 -Wesley

[@MetalSonicReject]

So I’ve got a question about rogue-like generation: how do you make certain levels fixed, like boss levels?

[@GDevelopApp]

If it's fixed, and you don't want it to change, you should make it by hand in it's own external layout, and spawn that in instead of a randomly generated level when they reach that floor/area. -Wesley

[@josesanchezart1244]

I got the down generation example working but I want it to go up instead of down. I tried so many ways to reverse engineer this but it’s not working properly. Any help would be nice.

[@GDevelopApp]

All you should have to do is change the Y position event to check if the player is getting closer to it from below instead of from above. Going upwards is negative, so that part will work differently, but otherwise it should be the same. Hope that helps. 👍 -Wesley

[@bonbon5000]

Such a useful tutorial, this will come in super handy Altho, is there a way to optimize the code of the drop down generator even further? Like for example: Subcondition: Empty Action: Create objects from external layout named "Section" + VariableString(Random) Delete BottomChecker Will that work by chance?

[@andreaguli6707]

2:00 I don't understand why my rooms overlap...I copied the code shown but it does not generate the rooms well I checked for hours but I do not find anything wrong, can someone give me some help?

[@GDevelopApp]

If rooms are spawning on top of each other because they've branched out and looped on themselves, that's normal. There s an event in the video that restarts the scene if that happens until it finds a level that doesn't spawn that way. If multiple rooms are just spawning in the same place then something is going wrong with the checker object. Either it's not being deleted when a room is made, or the rooms aren't being created at the position of the checker object. I'd personally try to do just 1 direction of room generation first, and then try 2 directions, and work your way up to all 4 directions. So you can more easily figure out where things are going wrong. -Wesley

[@andreaguli6707]

@@GDevelopApp thanks for answering, I inserted in the code that "when the rooms collide with other rooms the dungeon regenerates" the problem is that I see that generates rooms but in the end leaves me only with the initial one

[@TomLis-u3o]

If you are generating random unique rooms, how do you make sure that the same room wont repeat in gameplay?

[@GDevelopApp]

This video doesn't cover unique rooms, just the pathway that they can take. To make sure rooms don't repeat, you would probably want to use an array. Put the name of your external layouts in that array, and then when you create a room, pick one of the variables randomly and delete it from the array after creating the room. That way they can only be created once. (Just make sure it's a scene array, so it refreshed the list every time the scene restarts.) We have a video about structures and array variables that might help: kzbin.info/www/bejne/n6OqZZhofdSUe9k&ab_channel=GDevelop -Wesley

[@erwinregele]

i'm a beginner and now i'm making my first game (something like mario), out of curiosity i wanted to see this tutorial for another possible game, but my god it seems too hard, maybe after some time i'll understand the program better and i'll be able to do things like this

[@GDevelopApp]

That's fair. Things like this seem far less complicated when you get more comfortable making games, it's a lot though when you're first starting out. Best to start small. 👍 I always suggest people start with a platformer, wave defense, or "dodge the falling object" game. 👍 -Wesley

[@Hey_ImEvil]

I have a question, I have an enemies that in certain attack frame will create hitbox to hurt player. But if there 2 hitboxs collide with hurtbox at the same time It got messed up, like if there 2 meteor hit at the same time, they wont get destroyed or if 2 enemies touch the player, it only count as one touch. I hope I am being clear :p

[@GDevelopApp]

Try using the "repeat for each object" type event, and be sure to select the bullet/attack object. 👍 If 2 objects collide at the exact same time, and there's a single event that doesn't repeat, then it'll only trigger once and only count as having happened once. -Wesley

[@Hey_ImEvil]

@@GDevelopApp oh I see thank you so much

[@adi1161]

what should be entered in the X and Y Origin when creating external layouts ??

[@GDevelopApp]

When you use an external layout and put it in to your game scene, it'll create the layout from the 0,0 point of the external layout. So the top left corner of your external layout is going to be at the point you put in for the X and Y. So with the dropping down example at the beginning of the video, I put an object there, and put it at the bottom left side so all of the external layouts will be created in a line. So for the falling down example, use the X and Y coordinates of the object you put there. Hope that helps. 👍 -Wesley

@@GDevelopApp I tried creating a side scroller but i failed at it! as soon as i got in distance with the checker a lot of objects got created but the previous ones did not get deleted and got overlapped

@@adi1161 Is the delete "checker" object, the object you're using to spawn the positions with, is that part of the action where you're creating the external layout?
