cpp
unsigned int VAO;
glGenVertexArrays(1, &VAO);

how do I write that one, can't find the alt in the docs

oh nvm its createVertexArray

fun hunting them down lol

lol

huh weird, it doesn't show up in auto complete

language server moment

its in the docs though

yeah it exists

wait im using context.webgl

vertex arrays are a webgl2 thing I think.

I don't find it in

WebGLRenderContext

oh wait webgl2

mb

yh it shows now 👍

Note that it might not actually work, iirc 47rooks had some issues with it.

well, we'll see

For native targets, it appears

createVertexArray

is only supported on Linux and iOS/tvOS.

ah

I thought I used that on Windows

how do I write that in haxe

Yep it worked for me

3 * gl.FLOAT?

Yep

aight

No,

3 * 4

.

float

is a 32 bit floating point number, and thus takes up 4 bytes.

ohh, okay

normally actually I use things like this n * Float32Array.BYTES_PER_ELEMENT

you can also check the gl version by something like

(context.webgl2 == null)

or same for context.webgl, context.gles3 and context.gles2
