  • Hi, I was wondering why I cannot create a hierarchy between a sprite and a tilemap, I really frequently use the hierarchy system to spawn for example a dungeon room from 1 sprite, but I am stuck because I cannot add the tilemap as a child for the 1 sprite.

    usually the option "add selection to this instance" is visible, but when I try to do the same with a tilemap, it just doesn't work...

    If someone knows an alternative / how to fix this, I would like to know...

    thanks

  • I was wondering this too - why hierarchy is not supported for tilemaps? Ashley, could you explain?

  • IIRC it was complicated and it's not clear why it would be necessary so it was omitted.

    Tilemaps are usually used for large-scale level design. Why would you need it as part of a hierarchy?

  • I have two popular templates where random levels are built from "scenes", each scene contains a small tilemap and other objects.

    All scenes are currently stored on the main game layout, which is pretty messy. It would make sense to move all those scenes to a separate repository layout and use the new Templates feature to spawn them. But because tilemaps can't be added to the hierarchy, this is not possible.

  • Can't you just use two 'Create object' actions - one for the tilemap and the other for a hierarchy with its content?

  • Ashley yes we can, but only if we have a different object type for each hierarchy we want to spawn in! And when I need to update a tilemap, I need to change the texture for all of them... I feel that doing all of these extra steps while almost every other object type can be part of a hierarchy is quite annoying. If there was at least a way to create a hierarchy with tilemaps (even if you cannot change the angle, the size with the parent) It would be really useful...

  • Ashley yes we can, but only if we have a different object type for each hierarchy we want to spawn in!

    Doesn't the new templates feature fix that?

    Templates may help to spawn the right tilemap instance, but there may be cases when this will not work.

    In my example, some scenes may not contain a tilemap. If I create a scene by template and then attempt to create a (non-existing) tilemap instance with the same template name, the default instance of the tilemap will be created. By the way, this seems like a bug, I think if the template doesn't exist, then the instance should not be created. Like when you try to create an object on a non-existing layer.

    Of course, it's possible to find workarounds, but they will require a lot more effort. It would be much easier if tilemaps supported hierarchy.

    Hi there! Sorry if you already've seen my other post, but in case you missed it, I wanted to make prefabs/modules for a runner and it would be much organized to make the whole ground block face one big object (tilemap) instead of having a dozen on each module. It also may help performance 🤔?

    This is close of how one of the modules would look. Without tilemap hierarchy, each tile has to be a separate object. With tilemap hierarchy I could save on object count 💸💸💸

    ANYWAY

    I could deal with it if the team thinks it's not worth the work for something that can be replaced with a lot of objects (in my case).

    Cheers

  • I posted a suggestion:

    +1, I added a comment about why Hierarchy should support all kind of Plugins, even non-World Objects, such as Arrays and Dictionnaries to pick them in a better way and to workaround the fact Array and Dictionnaries aren't native data type such as strings or numbers
