Ok so i I get it right, beside of load state from JSON, I also need to save the object name and then use the create by name action (like "-> System: Create object "SpriteFam" on layer 0 at (0, 0), create hierarchy: False, template: """) ?

I really am a rookie with the array so how can I add the sprite's name on it after -> MyArray: Insert SpriteFam.AsJSON at index 0 on X axis ?

Hello everyone,

I read a very efficient way to save each object's proprieties in with AsJSON on this topic:

construct.net/en/forum/construct-3/how-do-i-8/save-sprite-properties-json-166321

But why doesn't it works with families? I tried to reproduce the same code but on family's objects and even if it keep all informations (positions, angle, size, etc…), it display randomly every objects from the family.

Here is the code I use

And here is the messy result I get

Is there a way to fix this?

Same for me. I just started to understand how arrays are actually working and I really need to get the logic about it.

But I did get an important information: all objects has a AsJson expression.

That's mean that everything about a sprite (size, position, actual frame, etc…) can be saves and load quite easely. Even variable I guess.

It you create an event to save everything in your array like:

+ System: For each Sprite -> Array: Insert Sprite.AsJSON at index 0 on X axis

Then if you want to call it back:

+ Array: For each X element -> System: Create object Sprite on layer 0 at (0, 0), create hierarchy: False, template: "" -> Sprite: Set from JSON string Array.CurValue

Seems it works pretty well but I encountered a major problem: This is not working with families. It can't recognize sprites with their name and it mix everything when you call it back.

And that's a big problem because I don't want to put this for every single sprite in my game (yep, I'm lazy XD).

For now I have no solution.

But even if I need to figure it out, I need to assign a new variable for each room that every single sprite in it can refer to.

And I may have the solution for this with the mini map I'have created here:

https://www.dropbox.com/s/yemjzks3vwv11xf/LevelGeneratorTest.c3p?dl=0

For now it's not that bad even if I didn't really figure how to detect the entrances of the rooms already created, but I'm going on.

Ok I think I get it (a bit). I thought I could save every new room created in a JSON without using arrays. In the end there will be a lot of informations and variable for each, it could not be the easiest way to manage it.

I also started to make a mini map. The interesting thing is that I can also probably save variables on it like "how many entrance there are in a room", etc… So when the player come back in it, the mini map could maybe ask the JSON all the stocked variables to "rebuild" the room?

Hi everyone,

I am currently testing a level design where several rooms are generated randomly. Each time the player changes room, a new one is loaded and the player finds himself at the entry point of this one (a bit like Cult of the Lamb).

For the part of loading the presets rooms I was inspired by dop2000's demo (congratulations to him, it's really well done, you can find some of his demos here).

My player can therefore move from one room to another but however, I have not found a way to save the rooms he has already gone through.

For example, if I want the player to go back, it will randomly load a new room and not the room he has already visited.

I think there is surely something to do by saving the data in an array or a json file for example but I don't see how it could be done.

Besides, it could also have a mini-map which is built simultaneously according to the progress of the player.

If anyone here has a method or a solution, I'm all ears!

You can already test my progress on this file, the purpose will be quite different but it is a basis for understanding how it works.

Hello, so for everyone who is looking for a solution about this, you can check this file.

Hope it will help a bit!

Hi! Thanks a lot GeoffB, I can see now that it was close with my previous version.

So, I tried to change my version [here] but I still have some questions with it. How am I supposed to link my sprite to my 3d shape's face as it seems in the end that it take it randomly? I mean, specify the UID in the instance is working fine but in the end I cannot choose which one of my sprite displayed on the scene will be choose by the 3d shape. There is something I definitely don't get because if I add new 3d shape and sprite in on your sample it works fine but not with my mine… How is it possible? (and why don't you use containers as it was suggested by Ashley on the other topic?)
