scripting interface TileMap.tileToPixel returns input

[mrmasterplan]

As the title says. Using the scripting function TileMap.tileToPixel(x,y) in a registered custom file writer returns the input values instead of the pixel coordinates as described in the documentation.

Ah, I'm afraid that currently this conversion function only works for opened maps, and not for maps that are being saved or maps that have been created using new TileMap(). This is because it relies on the MapRenderer instance to do the conversion and this instance is stored in the MapDocument, which is only available for open files.

But of course this function should always work, so we'll need to figure out some solution. The EditableMap class could instantiate its own MapRenderer, or the MapRenderer instance could be moved from the MapDocument into the Map. For the former I'm not too happy with the duplicated code and instance, and for the latter I'm not too happy about instantiating a renderer at a level where it's not always needed. Maybe it would be enough to create it on-demand.

It is almost not worth fussing over. This is the workaround I am using for now. https://github.com/MrMasterplan/rwklevelfiles/blob/925111188919081b03ad8c670f797b6c964d739f/tiled/dotkitty/index.ts#L202

Right, in that case the workaround is easy, though it becomes rather more tricky / annoying if you need to support non-orthogonal maps. I'm currently running into this issue while trying to look into MikeMnD/tiled-to-godot-export#26. :-)
