Two hight block of crop

[Jefrygg]

How to change a block model script so that the plant is two blocks high?

Plant model:

{
    "variants":
    {
        "age=0": { "model": "wof:cornbottom0" },
        "age=1": { "model": "wof:cornbottom1" },
        "age=2": { "model": "wof:cornbottom2" },
        "age=3": { "model": "wof:cornbottom3" },
        "age=4": { "model": "wof:cornbottom4" },
        "age=5": { "model": "wof:cornbottom5" },
        "age=6": { "model": "wof:cornbottom6" },
        "age=7": { "model": "wof:cornbottom7" }
    }
}

Try looking at the vanilla code for tall flowers or even the door. I'm sure those will provide enough information to be helpful. Their code shouldn't be specific to being a normal plant or door.

[Jefrygg]

First, how do I find vanilla codes and which block to look for?
Secondly, even if I find the code I need, how will I combine it with the CROP BLOCK code.

Which IDE do you use? In Eclipse, it is usually the first item in Referenced Libraries. There's a jar for forge/minecraft, a jar for the launcher, and a client-extra jar that contains client stuff like models etc.

You would just make your crop 2 blocks high or whatever in the same manner the vanilla crop does.

[Draco18s]

You're going to need to do some fiddling about, but its possible to do.

I tried to combine the "BlockTallGrass" script with my script, but it didn’t work.

What does the upper half of your block sit on top of? Is it farmland?

When your crop grows, I don't see it doing anything about setting an upper block.

I don't see anything about the block knowing if its an upper or lower block.

This is not the two-tall grass block class. This is the one-block grass block class (called "tall grass" because it isn't the grass block that has a green top face and dirt bottom face), which is why:

That enum exists. Two tall grass cannot and never is "dead bush."

This is the condition under which the plant will grow under the farmland block.

There are no objections. I will look for another. If you know where the tall grass script is, let me know.

This indicates the age of the plant and not the growth of the plant.

You still need two functional blocks. A top half and a bottom half and you don't have two halves!

So I don’t know how to do it yet.

You need two blocks if you want something two high, that is what vanilla does for doors, etc. as well.

Try looking at the vanilla code for tall flowers or even the door.

Well, I can only find this.

How can I combine it with the crop script.

It's not simply a matter of combining "scripts". You need to see and understand how vanilla minecraft makes a block "be 2 blocks tall", which is really *2* blocks, and when it grows, the bottom block checks if it has the top block, if not, it adds it when it grows.

 

Since it has not been asked, it's up to me: Do you know Java? How much programming experience do you have?

I can tell you that without some programming and/or Java experience, you will not have a good time trying to make a mod.
