Interface RenderContext

public interface RenderContext
Drawing for screens and HUD widgets, the same on every Minecraft version. Coordinates are GUI pixels (Minecraft's scaled units); colours are ARGB (0xFF12141A). Never touch OpenGL directly – this keeps addons working when Minecraft changes its renderer (1.21.6, 26.x, Vulkan).
