Quote from yourock129

Could you make a tutorial where if you right click block X with item Y in your hand, item Y turns into item Z. If that makes sense

item Y(in hand) + right-click on block X = item Z

Don't use regular Paint. It replaces transparent pixels with white pixels.

Smart, but you need the pictures inside of your Minecraft.jar

thank you, but I was using adobe fireworks

Quote from outcastjack

remove the Item. infront of the item name e.g.

ModLoader.AddRecipe(new ItemStack(Block.dirt, 1), new Object[] { "XXX", "X|X", "XXX", Character.valueOf('X'), Item.ingotGold, Character.valueOf('|'), myItem});

Item.myItem doesn't work, however mod_classnamehere.myItem does and is necessary to use for inter-mod recipe

p.s. inter means between different ones i.e. international

Thanks, but I already got it. And I don't use mod_classnamehere.myItem, I just use myItem... and it's working. Any problem?

Updated the achievement section on how to use "offspring" achievements, and making an achievement "special".

So I've got some code written. How do I get it compiled?

Also eclipse is warning me that I don't have a Java 1.6 compatible compile installed. I have 1.7 installed.

Thanks in advance.

You can use paint.net. It's free, and allows for transparency. (MS paint doesn't).

You set your block ID to 20. 20 is occupied by glass, change it to something over 123 and below 255.

When defining drops, recompile doesn't recognize Random in this:

public int quantityDropped(Random random)

and

public int idDropped(int i, Random random, int j)

Did you import Random into the class? I think I left that out, I'll add it into the tutorial now.

EDIT: Fixed it, have another look at my BlockName example if you don't know how to import it.

I had a thought: I should make stairs for my mod. Problem: I can't find a tutorial on how to make stairs. Different thought: Could you make a tutorial on that? (also half steps?) no rush, but it would be cool if you made one. (I think that it would similar to the flower tutorial but I don't know)

Um, I did that and it said that their is an error with this line:

public Blocknamehere(int i, int j)

it says that there is an "invalid method declaration" and that "return type is required"
So, not sure what that means but I thought I would ask.

Oh sorry my bad, you know where it says setBlockBounds(stuff);
Put that at the end line so:

public BlockTrampoline(int i, int j, boolean on) { super(i, j, Material.wood); setBlockBounds(0F,0F,0F,1F,0.5F,1F); }

super has to be the first thing there

OK, got it, thanks but I must ask: why are you posting in techguy's tutorials?
Also: Do you know how to make stairs?
