[1.15]Types of rendering methods and proper use

[Zemelua]

Since I am writing using a translator, the text may be a little unnatural. sorry.

 

 

I want to display my magic points in the same way as the health bar and food bar (the magic points capacity is already complete).

After searching, I found that I could use RenderGameOverlayEvent, but it seems that there are various ways to actually draw. blit? buffer? Can you explain because I don't understand the difference between them? Also, it would be helpful if you could write the sample code as well.

Check ForgeIngameGui, most of UI rendering are done there.

What is the difference between ForgeInGameGUI and InGameGUI of minecraft?
