So i’m used to dealing with projection pretty often where the formula is:

```auto
x += Math.cos(angle) * offsetX;

```

But I’m working on a project in Box2D where units are in meters (aka a lot smaller) and it seems if the offset is anything smaller than one the formula messes up. Anyone know a workaround for this?

\*Note: this value is later translated into pixels so every bit counts.
