The new EntityLightingBolt(world); is giving me a error and eclipse is giving the choice to pick from:

Add arguments to match 'EntityLightingBolt(World, double, double, double)'
Change constructor 'EntityLightingBolt(World, double, double, double)': Remove parameter 'double, double, double'
create constructor 'EntityLightingBolt(World)'

Make it

EntityLightningBolt bolt = new EntityLightningBolt(world, entityplayer.posX, entityplayer.posY, entityplayer.posZ);

This will spawn a lightning bolt right on top of you though, and you will most likely die lol.

How can you make a mob that will act like pigmen in when you hit one they all come hunting for you?

I'm watching you right now, and in hopes you can explain where I went wrong in coding. I'll let you know what I think when I watch a few of your videos.

I gave you a + for a a great tutorial. I love them, and you even make me laugh sometimes too. Keep up the good work.

Wahh is there anyway I could attach it to a snow ball so were ever the snow ball hits it will lighting. Also then how did you get
Your lighting wand to work in your magic mod?

Do you know how to use a certian colour of dye in a recipe fro example cocoa beens?

Look for PowderDye or DyePowder I forgot which one, and look inside the class there is a specific constructor that means different things. I don't know it off the top of my head, but I know it's a 3 variable constructor and in the class it tells you which number is which dye.

I combined the Bow with Lightning Bolt and made it so you shoot a "projectile" at something, and wherever it lands I did "entityJoinedWorld(LightningBolt)" at that position.

Congratz, i got in 1st day and lvl 20 now. How you liking it so far?

I'm loving it, played it till 6am last night :tongue.gif:

I have 3 doubt/questions:

1.- Is there some limitation on how many new Materials you can add to the EnumToolMaterial class? Beacuse I had no problem adding 1 and a tool, but after attemping 4 additional ones (an one respective tool for each) minecraft crashed.

2.- Can there be only one GenrateSurface method per mod_ class? I tried adding a second one for a different block but Eclipse marks it as a duplicate.

3.- Could you do a Nether Block Generation tutorial? I tried what seemed to be the most obvious way and it unsurprisingly didn't work.

Great series, BTW. Keep up the good work.

I'm getting a graphical error for my custom item (turd). Its graphic doesn't show up, but it is still minable. After a while, I get this error:


My coding is this:

hey i did everything that you did in the mob tut but i got this error when i tried playing it in eclipse

I couldn't really tell you the cause of that, it can't find your mod_ class? Maybe try to rename it without the second _?

1. I don't know, I've been trying to pick this class apart because so many people say you can do it without modifying that class, which I know and I get, but you would still be using the same ID's as other mods so they would clash anyways.
I guess it only accepts a certain amount of materials? I'm not too sure about this.

2. Put two for loops inside of the same GenerateSurface method, there can't be two of the same methods in the same class.

3. I didn't really try this out yet, I thought it'd work just like the surface one but I'll look into it.






In other news... Item Durability and Item Consumption video will be out in about 30 mins.

there is only 1

i then tried to edit the egg and I put all the code into comments (//code bla)and i still got the same error?

How to make mountable+controllable entities . :smile.gif:

Great tutorials! I'm waiting for the "new enum class" tutorial, but keep up the good work!

Why did you set the coordinates of the lightning bolt to be icon index? That's the id of the texture of the item...
Set it to be posX, posY, and posZ.

I dont know haha...whoops but i changed it to , And it kinda works except the lighting land right on me and then the snowball goes normaly were ever i throw it.

 world.entityJoinedWorld(new EntitySnowball(world, entityplayer));
        
EntityLightningBolt bolt = new EntityLightningBolt(world, entityplayer.posX + 2, entityplayer.posY + 2, entityplayer.posZ);

world.entityJoinedWorld(bolt); 

And it kinda works except the lighting land right on me and then the snowball goes normaly were ever i throw it.

Thanks for the reply. Here are some request for whenever you have the time:

-Mob drops management (mare than one tipe of item dropped, rarity of each drop, etc.)
-Generating new flower-type blocks (plants)
-Biome-Specific Block/Ore generation
- World features (ruins, dungeons,etc...)

Also, this is more of a doubt than a request, but is there a way to set a specific height level for a block to generate rather than just from the bottom of the map and up?(i.e. a block that would only generate on the surface or on mountain peaks)

Robby, you missed my question. It's on page 7.

You need to set the attributes to turd inside of the constructor, same as your block. You set it inside of GenerateSurface.

I was looking for something easy to record today cause I don't have much time, so I'll do that mod drop rarity thing today :ohmy.gif:

As for the block thing goes, you can make a block generate in a certain y value, for example only spawns from 50-55 Y. I'm sure you can make it spawn ONLY on surface, like grass, but I haven't looked at it yet. I suggest you look at the grass class and copy something in there.

Hey x2robbie2x, Love your tutorials! But could you do one on giving items special properties, like worn armor and weapons special properties?
