Class GlVaoSafety

java.lang.Object

com.hbm_m.client.render.GlVaoSafety

public final class GlVaoSafety
extends Object

Helpers for core-profile VAO rules.

Binding a shared empty "dummy" VAO instead of VAO 0 breaks vanilla and Iris draws (drawElements can crash the GL driver) because the dummy has no vertex buffers or element array. Use bindVertexArray(int) for normal restore/unbind; reserve withAttribEditVao(Runnable) only when code must call glVertexAttribPointer / glEnableVertexAttribArray and the current binding is 0.

Method Summary

Modifier and Type	Method	Description
static void	bindVertexArray(int vao)	Exact VAO bind, including 0 (unbind).
static int	currentBinding()
static int	getDummyVao()
static void	withAttribEditVao(Runnable work)	Runs work with a non-zero VAO bound so attrib pointer setup is legal.
