Converting Matrix4 to Float32Array via the builtin float32Array() method after a while results in:
error: Uncaught (in promise) TypeError: Cannot perform Construct on a detached ArrayBuffer
return new Float32Array(this.#internal);

part of the code that produces this:
(inside a render function which gets called every frame. not async)
const projection = new PerspectiveFov(
new Rad(Math.PI / 4),
800 / 600,
0.1,
1000,
)
.toPerspective().toMatrix4();
const view = Matrix4.lookAtRh(
new Vector3(-2, 0, 2),
new Vector3(0, 0, 0),
new Vector3(0, 0, 1),
);
const model = Matrix4.fromAngleZ(new Rad(this.t));
// lil hacky, but i know that the uniformbuffer is at index 0
state.device.queue.writeBuffer(
this.state.bBuffers[0].buffer,
0,
model.toFloat32Array(),
); // this doesnt. this gets updated with the value t, so i guess it has to have something to do with that
state.device.queue.writeBuffer(
this.state.bBuffers[0].buffer,
64,
view.toFloat32Array(),
); // for some foking reason this erros eventually with `TypeError: Cannot perform Construct on a detached ArrayBuffer`
state.device.queue.writeBuffer(
this.state.bBuffers[0].buffer,
128,
projection.toFloat32Array(),
); // this aswellbut as the comments say, the matrix which gets created every time with a different value (this.t) doesnt have this problem. not sure why.
EDIT: current fix is to call toFloat32Array() directly. like this:
const view = Matrix4.lookAtRh(
new Vector3(-2, 0, 2),
new Vector3(0, 0, 0),
new Vector3(0, 0, 1),
).toFloat32Array();
