Report content RSS feed Minecraft's Plan for mods and api

After some internal discussion and general anxiety, we've arrived at a plan for supporting mods. Mod api access will be free.

Posted by Xavia on Apr 26th, 2011

Here is the official Minecraft mod plan via notch's blog:

  • Let players sign up as “mod developers”. This will cost money (edit: no longer costs money! - see below), and
  • will require you agreeing to a license deal (you only need one per mod team).
  • Mod developers can download the source code from our SVN repository.
  • As soon as we commit a change, it will be available to all mod developers, unobfuscated and uncensored.
  • Mod developers get a unique certificate for signing their mods. This means players can see who made what mod and choose to trust individual developers. The cost of signing up makes sure only serious developers have access to this certificate.

The rules of the license deal will contain:

  • Mods must only be playable by people who have bought Minecraft
  • You can’t sell your mods or make money off them unless you’ve got a separate license deal with us
  • The mods must not be malicious (obviously)
  • We retain the right to use your mod idea and implement it ourselves in Minecraft. This is to prevent the situation where we have to avoid adding a feature just because there’s a mod out there that does something similar. It’s also great for dealing with bug fixes provided by the community.

In the long term, we hope this means people will do awesome new things with the Minecraft engine and play around with it. We want to buy and/or license good mods and/or total conversions and sell them ourselves. It’s possible we might have a mod marketplace for selling and buying mods that fans have written, or we might purchase and integrate nice mods that fit the main theme of Minecraft.

UPDATE: Cost of the mod api via notch's blog

Because of overwhelming feedback, the cost of the mod api access will be 0 dollars.Our intention wasn’t to make money off selling the access, only to ensure some level of quality. Obviously that wasn’t the most popular idea in the world.

ModDB's Thoughts

Great to see a commerical game really really think through it's modding strategy and realize the immense benefit robust modding tools and API can bring. We are going to see how closely we can work with Minecraft to provide mods with profiles containing image galleries / videos like they have on ModDB.

YESYESYESYES I love you so much notch, this will make me very very happy. Now... on another note, please don't sell too many mods. Cause if that happens then it'll be painful just having to "BUY" different mods all the time to play on different servers. I mean obviously this is up to the mod developers =P but I guess yeah if its a different license. idk xD

If you bought minecraft in alpha, then you already have access to all addons to minecraft.

Sorry, I kind of snapped as I watched a pointless game like this sell so much and still want more by selling the work of other people, destroying the ideology of mods I know them.

Just to let you guys know, I bought this game to play with a couple of friends and I completely regret doing so.

I mean... its better then buying a game and not getting any updates for it. its not like these modders are getting stolen from, they ARE submitting it willingly I should say. AND they're getting compensated for it... seriously what's not to like? I mean I'm only worried about server compatibility

now i do agree, mods should be free, and the whole "pay for making mods thing" shows of into his greed
however, the game is good and he definitly deserves the money, its not the graphics that makes it good, its the concept.

Paying to be able to mod? (Glad you had the common courtesy to retract that!)
Retain the right to steal any mod and incorporate it in Minecraft??
Selling and buying mods???

WTF am I reading!?
Mojang has become the Activision of indies.

I'm glad there is still the Wolfire Team, or I would've lost faith in humanity.

Selling total conversions sounds rather fair, selling minor mods is milking it rather too much.

When I read the part about buying a linsence to mod, alarm bells started ringing. Glad thats not gonna be the case anymore, I can see the idea behind it, but no it would have just been a bad idea.

I guess i'll wait and see how it pans out.

Judging by the sheer amount of both pos. and neg. comments to this news, " Minecraft " is clearly much more successful than many of us might like to admit.

I don't play myself, but let's see if " Minecraft " modders can change my mind !

Why do you HAVE to go to a post about a game that people obviously like, then just respond to comments and bitch about how much you hate it? Why do you ************* play games you don't like? That's like eating a whole bunch of food you hate, then bitch about how much you hate it the whole ******* time.

No, new mods will have access to a lot more of the games code, allowing them to do more things. Some mods may be incorporated into the game and made "official", but that's not anything new for minecraft.

There are already free mods on the minecraft forums. And some mods have had things before vanilla did(Example: Better light, Cookies from Humans+ mod), i just hope that if they're going to incorporate mods into the game, that they give appreciation to the modder who made it. It rips my soul in two when any game takes a mod and claims it as their own original idea.
