enum TrackState

This is the tracking state of a sensory input in the world, like a controller’s position sensor, or a QR code identified by a tracking system.

Enum Values

Inferred The system doesn’t know for sure where this is, but it has an educated guess that may be inferred from previous data at a lower quality. For example, a controller may still have accelerometer data after going out of view, which can still be accurate for a short time after losing optical tracking.
Known The system actively knows where this input is. Within the constraints of the relevant hardware’s capabilities, this is as accurate as it gets!
Lost The system has no current knowledge about the state of this input. It may be out of visibility, or possibly just disconnected.


Controller Debug Visualizer

This function shows a debug visualization of the current state of the controller! It’s not something you’d show to users, but it’s nice for just seeing how the API works, or as a temporary visualization.

void ShowController(Handed hand)
	Controller c = Input.Controller(hand);
	if (!c.IsTracked) return;

		// Pick the controller color based on trackin info state
		Color color = Color.Black;
		if (c.trackedPos == TrackState.Inferred) color.g = 0.5f;
		if (c.trackedPos == TrackState.Known)    color.g = 1;
		if (c.trackedRot == TrackState.Inferred) color.b = 0.5f;
		if (c.trackedRot == TrackState.Known)    color.b = 1;
		Default.MeshCube.Draw(Default.Material, Matrix.S(new Vec3(3, 3, 8) * U.cm), color);

		// Show button info on the back of the controller
		Hierarchy.Push(Matrix.TR(0,1.6f*U.cm,0, Quat.LookAt(Vec3.Zero, new Vec3(0,1,0), new Vec3(0,0,-1))));

			// Show the tracking states as text
			Text.Add(c.trackedPos==TrackState.Known?"(pos)":(c.trackedPos==TrackState.Inferred?"~pos~":"pos"), Matrix.TS(0,-0.03f,0, 0.25f));
			Text.Add(c.trackedRot==TrackState.Known?"(rot)":(c.trackedRot==TrackState.Inferred?"~rot~":"rot"), Matrix.TS(0,-0.02f,0, 0.25f));

			// Show the controller's buttons
			Text.Add(Input.ControllerMenuButton.IsActive()?"(menu)":"menu", Matrix.TS(0,-0.01f,0, 0.25f));
			Text.Add(c.IsX1Pressed?"(X1)":"X1", Matrix.TS(0,0.00f,0, 0.25f));

			// Show the analog stick's information
			Vec3 stickAt = new Vec3(0, 0.03f, 0);
			Lines.Add(stickAt, stickAt + c.stick.XY0*0.01f, Color.White, 0.001f);
			if (c.IsStickClicked) Text.Add("O", Matrix.TS(stickAt, 0.25f));

			// And show the trigger and grip buttons
			Default.MeshCube.Draw(Default.Material, Matrix.TS(0, -0.015f, -0.005f, new Vec3(0.01f, 0.04f, 0.01f)) * Matrix.TR(new Vec3(0,0.02f,0.03f), Quat.FromAngles(-45+c.trigger*40, 0,0) ));
			Default.MeshCube.Draw(Default.Material, Matrix.TS(0.0149f*(hand == Handed.Right?1:-1), 0, 0.015f, new Vec3(0.01f*(1-c.grip), 0.04f, 0.01f)));


	// And show the pointer
	Default.MeshCube.Draw(Default.Material, c.aim.ToMatrix(new Vec3(1,1,4) * U.cm), Color.HSV(0,0.5f,0.8f).ToLinear());
