matter-js npm simply won't work

[DkeRee]

Alright, this is the first time I've tried leaving an issue so this will be a new experience for me xD

I tried using the matter-js npm to make a multiplayer game but....

[Error: Cannot find module 'poly-decomp']

I believe that this is a problem in matter-js itself and if anybody can shine some light into this situation it would be much appreciated. I'm using version ^0.16.0 according to the package.json

Where / when are you seeing this? What does your build config look like?

The solution is to npm install poly-decomp --save, see existing issues #949 and #559

Thanks man. I love how you are so responsive. I got it working! However, since you're here I got a new problem lol. It is server side and I used the npm. I tried emitting socket events with keycodes that the server would watch for and then "move" the corresponding body that way. I tried to use Matter.Body.translate() and it worked, but it kinda "forced" the body into the other body which made them spazz. Thus, I looked at my friend's repl and heused Matter.Body.applyForce(). I tried to use it, but it didn't work. When console logging the body.force in his repl, I noticed how the force object {x: 0, y: 0} fluctuates from 0 when force is applied, signifying how much force is applied to each side and that it goes down back to 0 because the force has been well, applied and it stops. However, in my case when console logging the body.force, it ADDS UP and the force is never applied. For example, I tried adding -0.5 to the y force whenever I held down the "w" button. It should have showed the y flucuating from 0 to -0.5 but instead it kept adding up and never got applied. So if I kept holding down "w" it would eventually add up to 100+ y force and never gets released.

Another quick update:
Figured that it was because I wasn't calling Matter.Engine.update(), but even after that didn't work.

var tickrate = 1000/60;
Matter.Engine.update(engine, tickrate);

It just simply still kept adding up. Also server side still.
