SpriteTile, a fast dynamic tile system (RELEASED)

Thanks, this works great now.

I notice a different issue with the camera rotation now in the procedural demo. ScreenToMapPosition does not seem to work correctly for mouse clicks. It looks like it assumes that the mouse click x/y coordinates correspond to clicking on the level when it is flat, not rotated. Is there a way to fix this?

Is there some way to convert the mouse coordinates to camera coordinates, then pass that to ScreenTo<MapPosition?

 

There's always some way. Unfortunately nothing simple is coming to mind at the moment; I'll keep thinking about it.

Can this be done using a raycast on the SpriteTile surface by adding a mesh filter and collider? And then pass the raycast hitpoint to ScreenToMapPosition.

I am just not sure where to make the changes in the SpriteTile source code.

 

No, since sprites are recycled so you wouldn't have colliders that are assigned to any specific tile. But raycasting is a good idea; I'd use Plane.Raycast, then you can use WorldToMapPosition.

That worked, excellent. Thanks!

 

I am using a perspective camera since the camera is rotated. Do you have any advice on how to keep the camera's viewport within the bounds of the level, as not to reveal the background?

 

I would say get the camera bounds as usual, then inset them by whatever number of tiles you added with the AddBorder number.

--Eric

 

Thanks, how would one go about getting the width of tiles and insetting the camera?

I was also thinking of calculating the number of tiles that can fit in the current viewport, and limiting movement based on the number of tiles the player is from the edge of the level.

 

You can use GetTileSize. So the bounds would be numberOfTiles * GetTileSize.

--Eric

 

Can we serialize the level data? I can serialize most of my other level variables in the same file, but don't know if it will work for a custom level?

 

The level data is stored in binary files.

--Eric

 

Tile.GetSize() returns (1.0, 1.0). Is there a way to get tile width in world coordinates or pixels?

 

That is the size in world units. (1.0, 1.0) means it's 1.0 units wide by 1.0 units tall.

--Eric

 

Would it be possible to have a "wall" group type like the terrain group?

 

Not quite sure what you mean, but you could use terrain groups to make walls if you like.

--Eric

 

I see, then the issue is the tiles will be different sizes because of the level rotation and the use of a perspective camera. And the tile sizes will change relative to the camera position.

Tough problem given the perspective camera. Will need to figure this out with some fancy 3d math most likely. Thanks though.

 

Ah, ok, will continue to do it myself.

 

Hiya. I've noticed that a cell without a tile (e.g. prefab) doesn't have the trigger value copied over to the new cell when it's cut/copied in the level editor. The properties do get copied over correctly though. Works fine when copying a cell with a tile.

 

Yep, I see what the issue is. You can fix this in the source, where in MapData.cs, change line 270 from

Code (csharp):

1.                 if (skipEmpties && map[sIntPos] < 0) {

to

Code (csharp):

1.                 if (skipEmpties && map[sIntPos] < 0 && !HasProperty (p)) {

--Eric

 

Thanks for the quick response and fix.

 

I haven't applied the fix above yet, but I've just spotted another minor issue in the Level Editor window.

When the Extra and Trigger overlays are both selected, cells without tiles (e.g. prefabs) don't have their Trigger value displayed. The Trigger value for them is displayed if only the Trigger overlay is selected (Extra overlay is unselected). Cells with tiles do correctly display their Trigger value with Trigger and Extra overlays both selected.

 

Hmm, I'm not seeing that (regardless of the fix above):



You have to zoom in fairly close though or else the prefab icon covers the trigger value.

--Eric

 

Yes, I see what you mean. You do have to zoom in very close to see it though.
Anyway, thanks for checking and letting me know.

 

I'm a little confused about importing from Tiled. I'm getting an error: "No tilewidth property found in tileset tag" and I don't know what I need to fix that, other than editing the XML manually. I notice the sample XML uses PNGs in the tileset tags – does SpriteTile not support Tiled maps that use .tsx tilesets?

 

As described in the "Importing a Tiled map" section in the docs, Tiled files require some manual work to import, including importing the tiles as sprites. The tilewidth and tileheight tags are used for informational purposes so you know what pixel sizes to use when slicing the tilesets. So no, .tsx tilesets wouldn't work. The tiles should be in some format that Unity can import, which would usually be .png.

Hey Eric, I just wanna let you know I've been using SpriteTile for years and I very much love it. Thanks for all the hard work you do man. I wanted to leave this here just because I have been saved so many times by this. You're a blessing. :3

 

Thank you, it's very nice to hear that!

Hi Eric

I've imported SpriteTile 3.2.1 into an empty project in Unity 2020.3.22f1 and the following errors are reported:

Assembly 'Assets/Plugins/SpriteTile/Editor/TileEditor.dll' will not be loaded due to errors:
Unable to resolve reference 'Boo.Lang'. Is the assembly missing or incompatible with the current platform?
Reference validation can be disabled in the Plugin Inspector.
Unable to resolve reference 'UnityScript.Lang'. Is the assembly missing or incompatible with the current platform?
Reference validation can be disabled in the Plugin Inspector.

Please can you help?

 

You'd need to copy Bool.Lang.dll from an earlier version of Unity into the appropriate place in the current version.
