The first 2020.4 snapshot - energy, doors and much more

Survey on contributors

As we announced, we are considering open-sourcing MCreator. As this alone without contributors does not make much sense, we made this survey to find out how many users willing to contribute we have.

If we go this route, we would release MCreator under GPL-3.0 license with exception to allow mods made with it use custom licenses. Contributors would have to sign CLA similar to the one we use for existing projects.

Keep in mind this survey is informative and not binding in any way, but please fill this survey only if you can and would contribute to the project so we can get a real insight into the status of contributors.

Legacy 1.12.2 generator

Although we no longer support or encourage the use of 1.12.2, we still want you to update to newer versions. For this reason, I updated the Minecraft 1.12.2 generator to support 2020.3. All new features are not supported in it, though, but feel free to open pull requests.

Keep in mind you need to install the plugin yourself. You can support development by contributing features (eg. add missing features from 2020.3) on

Finally some energy stuff! This is great!
I'm also very excited for player variables

I like the new style of changing through the different pages of mod elements, but can you please give us the option of switching back to the old style? Please? The buttons are too small for me to click easily :(

Tameable entities! :D

I hope there is a way to make mobs emit light!

unflameable option to blocks is a good idea,cause the only option is unbreakable and replaceable.

One bug i would like to see fixed is that when i leave mcreator after putting in a ton of work then exporting knowing ill have future updates when i exit it and then come back the next day half of my mod is deleted. I have the textures but not the recipes or tools. It has happened to almost all of my mods and when i use backups it also has half the stuff deleted (I made sure it was saving and it was) Please fix this as i have to abandon my mods because of all the hours i would have to waste trying to remake it. Thank you
