[1.7.10] Custom Painting Rendering Half Block Off


gottsch
 Share

Recommended Posts

Hi.

 

I am having a rendering issue with a custom painting. I simply extended all the painting classes as vanilla as possible, just changing the texture image to use (and of course to point to my classes). However, the image always renders a half block higher than it should. If I make the wall higher, then it will climb, full blocks higher. Has anyone encountered this before? ( I found one thread for an older version, but it didn't really help me).

 

Thanks,

Thanks, but that line is referring to the dimensions and offset of the image to display on the painting.  The enumart is referring to a property of EntityPainting:

 

    public static enum EnumArt
    {
        Kebab("Kebab", 16, 16, 0, 0),
...

So I just used the values to always use the first image.

Firstly, u should rename your params, it will make everything a lot easier.

Yes, I typically do.  I just threw this "basic" set of classes together to get it to work, as the actual version in my mod does the same thing.

 

And secondly, when u hover over the painting is the hitbox around the painting or is the hitbox half a block down? (Like the stone)

Good question.  I don't see the hitbox (black wireframe) even highlight when I hover over the painting.  The block's behind the painting will show their hitbox as if the painting wasn't there.

In your item, try changing:

EntityHanging entityhanging = this.createHangingEntity(p_77648_3_, p_77648_4_, p_77648_5_, p_77648_6_, i1);

to

EntityHanging entityhanging = this.createHangingEntity(p_77648_3_, p_77648_4_, p_77648_5_ + 0.5, p_77648_6_, i1);

Sorry that was my mistake, pretty sure entities don't have hit boxes

Thanks, but these params are ints, so this value will just get truncated back to the whole int value.  But for good measure, I attempted with +/-1.  The outcome was the same (just a full block in a different direction).

 

Just to make clear, the painting initially renders in the correct place, but then almost immediately shifts upwards.  If I add more block to make a higher wall, it will shift even higher depending on the way I look at it.
