Official 2D Tilemap Extras 2.0 released for Unity 2021.1

I have copy code from Unity classes. It's not my code. My code is strongly cached.

 

Some of the best solution will be add some sort of shadow tilemap(Like shadow DOM in html). We working like with standard tilemap, and on update it will updated, recalculated etc and applied on the real tilemap.

 

Thanks for your reply.

1. I had suspicions of memory allocation in those cases when I move to the side and draw tiles on new positions, and clear them from behind. Those. we create new ones, and old ones release memory. What is the best way to act in such a situation? I can't pooling tiles from the outside in any way. I'll test it more for sure. But what do you think?

2. As I see it so far. a nice implementation of a lazy single tile assignment that will collect all changes and apply them at the end of the frame.
Example: We are redrawing the entire screen (clearing off-screen tiles and drawing new missing ones) and don't want to create an array to update the package. Very difficult with this side on our side without any highlights. I don't store the map anywhere, and usually the seed for building the map structure by layer at runtime.
In my case, there will be a method that receives a single SetTile request but does not update the view. If the tile has not changed, then it does nothing. And two separate methods for recalculating tiles for implementations (for example, Tile Rule) and a separate one for redrawing. Perhaps it would be convenient to implement lazy application directly in the data of a particular tile by adding "a new tile that will be applied when drawing", so that you do not have to store an array of changes somewhere.
It would also be convenient to clear tiles that are not included in target region (int x, int y,int width,int height).
These two things made my script 80% smaller.

 

Not entirely about "extras", but is there a way to refresh a tile when any tile below is refreshed?

Basically, I made a tile which checks tile below it and sets own sprite and transform based on that. I need to call refresh for this tile when tile below is refreshed to make sure they are synched properly, but there is only Tilemap.tilemapTileChanged event available (which is not called when previewing tiles too).

My guess is that I have to use custom tile classes for everything that will call my own events, but is there some plans to expand what can be done with built-in functions if what I want is not avilable right now?

 

Yes, I've implemented it with custom tiles for now: other tiles now call custom Referesh event when they update their data, and I subscribe to it for now.

About what I needed that for:

I have a "shore" tile, and then I have "waves" tile which is supposed to be put on top of shore tile. They are separated because I animate waves with a shader. "Waves" tile got a sprite for each sprite varition "shore" has, so I'm looking at the tile below "waves" and select a matching sprite.

At first, I wanted to just spawn those at runtime with game objects, but then I got a need for more control over where "shore" tiles are put, so I'm placing them in editor mode in the end. I also tried to make "waves" as similar rule tile, but then it didn't work when there are 2 opposide-facing shores nearby.

As for "Tilemap.tilemapTileChanged", I'd like it to return what tile was in the cell before the change.

 

I want to update multiple tiles in a single call, the method I found is

Code (CSharp):

1. SetTiles(Vector3Int[] positionArray, TileBase[] tileArray)

, But it did not support offset and length, which means If the size of array of tiles I'm going to update is dynamic that I need to create a new array every time I call the SetTiles. The method I needed is like this

Code (CSharp):

1. SetTiles(Vector3Int[] positionArray, TileBase[] tileArray, int offset, int length)

and what I will do is only create a array with maximum possible length and then I will pass the offset and length if I only want to update a subset of the array
