I just started to make Minecraft mods with ModLoader, but i'm already stuck with my first block.

(All the classes are in the net.minecraft.src package)

Main class : http://pastebin.com/SKsC9rSs

MyBlock class : http://pastebin.com/UuaeGa51

Error: http://pastebin.com/7YHspTuj

300 is not a valid block ID.

 

It is, in fact already taken by, Leather Pants.

I also tried 500 just like the tutorial, that worked neither.

Wait, you're trying to make mods with ModLoader? What are you doing here at Forge then?

I tried to use the tutorial from here and Modloader is loading my mod.

EDIT: I used MCP to get the code for Minecraft.

Still doesn't explain why you're asking on the FORGE forums on how to use MODLOADER.

 

Forge != Modloader

Because I did this in Google.

Did you read why that returned as a positive result?

 

If you have a ModLoader mod that does not work with FML/Forge, *TELL US*

 

Coming here for modloader support would be like going to Bukkit forums trying to code a forge mod.  Sure, there's MCPC+ and Bukkitforge that provide cross-compatibility, but that doesn't mean that it's the right place to go for help.

 

You're probably best off going here and reading the last FAQ question.

Thanks for clearing that up, I'll take a look at their IRC.
