Draw in world like name tags

[Insane96MCP]

I would like to draw something like the player xp bar in the world when the player looks at a tile entity. I got the part to look at tile entity and right now I just show an actionbar text, but I would like to make things prettier.

You’ve kinda solved your own problem in the title, understand what happens when minecraft draws name tags, then make your own implementation. I believe the code for it is in EntityRenderer#renderLabel

Ok, I tried sending a packet from server when player looks at the tile entity that should show a nameplate like vanilla one, but there's some strange behaviour. The sky flickers everytime a packet is received and the nameplate doesn't show.

That's the packet handler https://github.com/Insane-96/XpHolder/blob/2.1/common/net/insane96mcp/xpholder/network/GetXpStored.java#L49

The position and the amount is received correctly.

Ok, managed to draw in the event but the nameplate still doesn't show for some reasons. I might be missing something

You might want to look at https://github.com/Cadiboo/WIPTech/blob/fb5883e9d76ef0361ec1ebbcb9c508611dd2ef6b/src/main/java/cadiboo/wiptech/client/ClientEventSubscriber.java#L228 and https://github.com/Cadiboo/WIPTech/blob/fb5883e9d76ef0361ec1ebbcb9c508611dd2ef6b/src/main/java/cadiboo/wiptech/client/ClientEventSubscriber.java#L358. Notice that I do some stuff to get the render position, which I then use for translations to be at the right position for my in-world rendering

I'm pretty sure I already have the right position

I don't see you doing any translating at all

I don't understand why I need to translate

I just tried copy-paste your code HAHHAHAHHAA
Btw yeah, I would like to understand why all this needs to be done

To change from render coordinates (on screen coordinates) to world coordinates (BlockPoss) you have to do some translations. This article explains it nicely https://www.quora.com/What-does-it-mean-by-world-and-world-coordinate-in-computer-graphics
