Update 2d_primitives.js

[unjust]

Found the docs a little confusing when trying to create a quad with z coordinates.
Clarify the ordering of arguments for quad.

If I'm not posting this correctly - to the correct repo or into the correct branch, let me know. (I just followed the links at the bottom of the docs)

i'm afraid this isn't going to work. the ordering of the parameters in the docs must match the ordering in the code.

[unjust]

ok I must be doing something wrong then because the params don't work as expected for me.

[Spongman]

Can you post an example here?

Looks like the 3D renderer only has a 2D implementation of quad:

p5.js/src/webgl/3d_primitives.js

Lines 1027 to 1064 in 9851414

	p5.RendererGL.prototype.quad = function(x1, y1, x2, y2, x3, y3, x4, y4) {
	var gId =
	'quad|' +
	x1 +
	'|' +
	y1 +
	'|' +
	x2 +
	'|' +
	y2 +
	'|' +
	x3 +
	'|' +
	y3 +
	'|' +
	x4 +
	'|' +
	y4;
	if (!this.geometryInHash(gId)) {
	var _quad = function() {
	this.vertices.push(new p5.Vector(x1, y1, 0));
	this.vertices.push(new p5.Vector(x2, y2, 0));
	this.vertices.push(new p5.Vector(x3, y3, 0));
	this.vertices.push(new p5.Vector(x4, y4, 0));
	this.uvs.push(0, 0, 1, 0, 1, 1, 0, 1);
	this.strokeIndices = [[0, 1], [1, 2], [2, 3], [3, 0]];
	};
	var quadGeom = new p5.Geometry(2, 2, _quad);
	quadGeom
	.computeNormals()
	._makeTriangleEdges()
	._edgesToVertices();
	quadGeom.faces = [[0, 1, 2], [2, 3, 0]];
	this.createBuffers(gId, quadGeom);
	}
	this.drawBuffers(gId);
	return this;
	};

This should be opened as an issue, I suspect

Right, any additional args past 8 just get ignored. At first I thought it was an ordering problem.

ok great. closing this and we can follow up with the issue you've posted. linking here for documentation #3328
