I want to add a method to the block, so if you fall on it without sneaking you fly back in the sky.

it shows no errors, but don't work.

	public void onLanded(World worldIn, Entity entityIn)
    {
        if (entityIn.isSneaking())
        {
        	entityIn.motionY = 0.0D;
        }
        else if (entityIn.motionY < 0.0D)
        {
            entityIn.motionY = -entityIn.motionY;
        }
    }

Is that function overriding a function from somewhere else?  If so, where's your @Override annotation?

no it's not, i think

And thus, your problem truly begins.

 

The thing is: there is a critical hook missing (onLanded in the block class) which is not easy to emulate with 1.7.

is it not possible to just add the method to block class?

 

Sure, you can add it. Except nobody will give a shit. Methods don't get called by magic.

that's how it's defined in 1.8:

    public void onLanded(World worldIn, Entity entityIn)
    {
        entityIn.motionY = 0.0D;
    }

Yes. But in 1.8 it is called from Entity#moveEntity.

1.7 will not do that.

is there any possibility?

 

Look at where onLanded is called in 1.8. Try to emulate that behavior in 1.7.

yeah i will try, could you say me how to add something to original source code? like new methods?

 

You don't. Especially not with your level of knowledge.

okay, thanks for your help

today i will ask a friend of mine, which programs in his job with java

You don't. Especially not with your level of knowledge.

i got it, but now i need to know why the block can't be moved by a piston

You don't. Especially not with your level of knowledge.

What material is it?  Does it have a TileEntity?

 

Both of these are very important questions you should have already asked yourself.

it has tileentity because it has a special model

And you started a whole thread for that, good jorb.
