Hi, I was overdoing it with Minecraft / particle because I didn't know the command so well anyway and now I can't play in mine anymore because Minecraft keeps hanging up. Maybe someone has a solution?
Give Minecraft more RAM, you can't do more in my experience
And how do I give more RAM, I play on Mac 🖥
You have to leave and re-enter the world. It worked for me too. I also had the problem when I exaggerated with / particle. You can read how to use this command here:
Edit the installation in the mc launcher
Ah ok, but I still found another way. You can also upload the world to a server and then issue the commands in the file server.poperties. Destroy the command block and download the world again
