I’m not really sure where this belongs so I’ll just leave it here. Below is a script that will parse a comma delimited text file into a 2D int array and then instantiate prefabs based on the integers of the array. Essentially it allows you to make tile maps from a text editor or tiled map editor (if you export to .txt, only supports 1 layer import).
Attach this script to a GameObject and specify Width/Height (in tiles, assumed a tile is 1x1 unity unit) and the filename including extension of your text file. By default it will look in your project’s Assets folder for the file but this can be changed in the first line of the Awake() function. This script also instantiates along the XY axis but can be easily changed for XZ, or YZ, or whatever you want.
