Hello,

 

I managed to copy and modify original cart to use my renderer. But I'm stuck on minecraft bug (it's not too much visible in-game because original carts are pretty symmetric) - the cart renderer does not "remember" (or use) a direction it's moving, so all south-north rails render cart's direction one way and a second way east-west rails - it renders always one rotation (for 2 moving directions). So when running in a circle, half of the time the cart is actually going backwards...

 

Not sure, if it's understandable so I'm adding a video:

 

Rendering (and a lot of minecart) code uses de-obfuscated but not "translated" names, I'm really lost here... Any ideas?

 

(code is here, but as I wrote I didn't changed it much)

 

EDIT:

I don't know the answer but you could try pming the creator of steve's carts or the railcraft mod creator.

I wrote a pm to Vswe (creator of steve carts). Some time passed but unfortunately he hasn't responded . As you wrote I should try asking also CovertJaguar, maybe I'll have better luck with him.

CovertJaguar answered my question . Here's his solution (I hope he doesn't mind):

Compare render yaw to server yaw and do a 180 if the difference is too large.

To prevent random switching on load, you must also write the isInReverse var to NBT.

It works like a charm (if you want to see actual code, it's available here)
