Loading tilemaps from project files using JSON and AJAX?

I'm trying to load a tilemap that I previously downloaded using the JSON download action. I placed this file in my project files and told the AJAX plugin to load it, and when it finished I told the tilemap object to load this tilemap. In the debug the JSON is loaded by the AJAX plugin but the tilemap doesn't change. Can anyone help me?

You need to pay attention to the expression and action you are using when dealing with tiles JSON. Objects have a common expression "AsJSON" that saves their entire state in a JSON string, and a common action "Set from JSON" to load their state from such a string. However, the tilemap have specific expression / action to save / load only its tile data, namely "TilesJSON" and "Load". You should be using "TileJSON" with "Load", or "AsJSON" with "Set from JSON", not a mix of both set.

Or maybe your problem is something else entirely, but we lack information to really help you.

I double checked that but i was using tile data download and upload for both situations. I think the problem might have to do with how I am referencing it. Right now I'm using AJAX.LastData to reference the string. Is that correct or should I reference it differently?

AJAX.LastData inside the "on completed" trigger is the way to go.
