This library is mostly a wrapper around the Linear library, which it also re-exports types, functions and operators from.

The most notable addition is Transform. A component that encodes the translation (position), rotation and scale of entities.

Transform is usually constructed with its Default instance, optionally specifying some of its fields:

insert (def {translation = V3 5 1 0})

To manipulate Transforms, you can import the following module:

import Mischief.Math.Transform qualified as Transform

This module contains a few useful functions, such as move which is used to update the translation:

Transform.move (V3 5 0 0) transform

Other notable functions are Transform.rotate. There is also Transform.rotateZ if you wish to rotate a 2d object.

You can add TransformPlugin to your app. This will propagate the transform of all entities through the ChildOf component. Basically, each entity's Transform will become their position relative to their parent.

This plugin also inserts the GlobalTransform component to all relevant entities, which is a wrapper around a Transform that's global.
