Hi, you can follow these steps to create an iconset from individual icon files:
1. Create a folder in your game project and place all of the icon files in there, do not use spaces or special characters in folder names.
2. Create another empty folder in your game project
3. Create an event in your game that calls the plugin command "Create IconSet" and for the Icon Folder argument, enter the name of the folder you created in step 1 (capitalization must also match exactly). For the Output Folder argument, enter the name of the folder you created in step 2. Row count should be 16 and icon width/height should be 32.
4. Start a playtest and interact with the event.
