[UNSOLVED][1.10.2]Need help with TESR and tileentity item

Leomelonseeds · February 5, 2017

Isin't the vanilla TileEntityChestRenderer like my renderer? Why does the lid open for the minecraft one?

Draco18s · February 5, 2017

Because it doesn't call new every time.

Edited February 5, 2017 by Draco18s

Leomelonseeds · February 5, 2017

wtf? I think I am missing something very stupid...

Draco18s · February 5, 2017

Why are you doing this?

Leomelonseeds · February 5, 2017

because of this:

float f = tec.prevLidAngle + (tec.lidAngle - tec.prevLidAngle) * partialTicks;

I need to create new if I want to do that, before it was the TileEntityChest te.

Draco18s · February 5, 2017

Every time you create a new one, those fields get set back to default.

You can't do that. You want those fields, put them in YOUR tile entity!

OK I addded the fields and stuff. When I tried to open the grill.... It didnt even open the gui and this happened:

so you dont want to put stuff in your slots ??

this will not localize you must use I18n#format(String translateKey, Object... parameters)

why are you playing every tick a Sound, look at BlockFurnace line 109 how MC is doing it

Why are you still using IInventory? Use the IItemHandler capability.

And no, don't make a second thread for the same problem.

Also, which GlStateManager.scale scales it so that it is a bit smaller than normal blocks?

You are still making a new instance of Grill. Use the one supplied in the method:

public void renderTileEntityAt(Grill te, double x, double y, double z, float partialTicks, int destroyStage)

See the Grill te part? It's the first parameter of the method. Use it.

For the crashing, do I have to do a null check in the TESR?

Leomelonseeds · February 9, 2017

Still not working:

 if(te.hasWorldObj() == true){
        EnumFacing facing = te.getWorld().getBlockState(te.getPos()).getValue(BlockGrill.FACING);
        }

(in TESR)
