Minecraft Forums

hey x2robbie2x, I just finished a mod which used several of your turorials concepts. I was wondering if you wanted to reveiw it.
ll give you a link if you do

I have a question. I am an pro Java programmer, started learning when I was like 9 years. The new ModdingAPI. -Does it change the background for coding? Like, the Java Developer Kit will be something else? I know everything about the (almost) former programming background, but nothing about the API.

Quote from Binary1011011

I managed to change little details so ti could fly but how can i make it fly up if i press space bar and how can I change the speed

Speed change may be a little complicated for begginers because it uses frictionate speeding-up.

1. Go to Risugami's mods, and under the ModLoader section there is a decompile fix download. Just download it.

2. Go to you MCP and go to src/minecraft/net/minecraft/src and drag the MLProp.java into the folder and replace it.

3. Restart eclipse, (assuming that is the program you are using), and go into your mod_ class.

4. Outside of you public void load method, write, for example,

@MLProp public static int newOreID = 145;

(You can make "newOreID" and the number whatever you would like.)

5. Then, inside of, for example,

final Block NewOre = (new BlockNewOre(145, 0)).setHardness(1.5F).setResistance(10F).setStepSound(Block.soundStoneFootstep).setBlockName("newOre");

Instead of a number as the ID, make it your, newOreID, or whatever you named that integer.

6. Recompile, and reobfuscate your mod, put the contents into your jar and run Minecraft.

7. Exit minecraft and in the .minecraft/config folder there should be a new configuration file for your mod.

Now you can open it up in notepad or some other text editor and change the ID of your blocks and/or items!

EDIT: Missed where it said in Step #5 to place the code inside void load.

great vids!
I just started making a mod. I've gotten to just putting blocks in the world but Im getting an error and have no idea what it is.

Can you help me?

Again, your bock ID is too high, it has to be under 256.

EVERYONE:
In 1.4.6, replace all

shiftedIndex

with

.itemID

Actually, the Block ID can be over 256, that's the maximum build height...

Quote from ZxBloodZ

No, go into block.
There's a line declaring an array called BlockList, with 256 Blocks. Therefore, 255 is the maximum block ID. This is because the array starts at 0. And look at item, find the lowest ID there. It will be 256, so >255 is Items.
EDIT:
the lowest Id will be 0, but shiftedIndex, the one the game uses, adds 256 to the variable you pass in as Item ID.

Hey there Robbie, love the tutorials! Seriously, without you i never would have been able to mod the simplest thing. Anyway, I'm trying to add a block to the world, but not an ordinary block - i want it to appear as a floating orb. However the standard block textures prevent me from making it like that since it defaults to making it, well, block-shaped. Should i declare the orb as a something other than a block? I was thinking maybe declaring it as a flower or something, but in all honesty I'm not sure where to begin. Thanks to anyone who reads this and can help.

What happened I will put my files here
https://www.dropbox....ustom_message=#

Hop u can help me

I think the ID you assigned to your ore is already being used by another block in Minecraft. Try another ID number.

This is really great tutorial!

But I have a Problem. I made a new block according to your video(Minecraft Modding Made Easy: Blocks, Ores, and World Generation. ).There was no error.

I did recompiling and Client Window loaded mod_blockium ..

But i could't find them.. I set x(16), y(40), z(16). I could't find them at y 40.

How can I fix it?

well i think it is good cause yeah maybe it wont help out much if you dont know java but i think this, i plan on being a software designer one day and i need to start learning code now and what better way to start than to mod a game i enjoy, what im saying is that i may not know what a class file is(i do just saying) but this can teach me some basic coding functions for mc then once i understand the basic in MC moding i will try editing other stuff and then try making my own short java game so this tutorial is useless if you want it to but i see it as a good stepping stone
