Introduction

Quick scratch Vectors and Quaternions for PlayCanvas to avoid constant definition of oddly named local variables and subsequent bugs!

Installation

npm install --save playcanvas-working-vectors

Usage

import {V, Q} from 'playcanvas-working-vectors'

...

this.entity.setLocalPosition(V(this.entity.getLocalPosition()).sub(this.enemy.getPosition())); 


let rotation = Q(this.entity.getRotation()).mul(this.entity.getRotation());

let rotation = Q().fromToRotation(this.entity.up, hit.normal);

let vector = V(0,0,distance).mul(this.entity.getRotation()); 

Notes

There are 2048 scratch quaternions and vectors used in a rolling buffer, allocation of more than this before a function completes will cause them to be overwritten. Values are for working purposes only and should not be stored between frames.

Requirements

Requires PlayCanvas Engine to be running on the page. Uses ES6/Babel/PlayCanvas template.
