my mod is not working

Could you elaborate further:

• Is it showing up in the mods menu?

If it isn’t showing up:

1. Did you press “export mod to distribution” in the workspace tab at the top of the MCreator GUI and it export a .jar file.
2. Are you sure you installed Forge properly, created an installation with it, and then placed jar in the mods folder,. (If unsure, here’s a tutorial: https://www.youtube.com/watch?v=VEyGJSE0XD8)

If it is showing up in the mods menu:

• Please elboarte on what exactly in your mod is not working 
• Maybe make a zip file of your workspace folder (“<your user folder>/MCreatorWorkspaces/<the specific workspace’s folder>”) and share it on it. That way I could see what’s going on in more detail.
