SystemInfo.worldRaycastPresent

bool worldRaycastPresent{ get }

Description

Can this device get ray intersections from the environment? If this is true, then World.RaycastEnabled can be set to true, and World.Raycast can be used.

Examples

Basic World Raycasting

World.RaycastEnabled must be true before calling World.Raycast, or you won’t ever intersect with any world geometry.

public void Start()
{
	if (!SK.System.worldRaycastPresent)
		Log.Info("World raycasting not available!");

	// This must be enabled before calling World.Raycast
	World.RaycastEnabled = true;
}

public void Stop() => World.RaycastEnabled = false;

public void StepRaycast()
{
	// Raycast out the index finger of each hand, and draw a red sphere
	// at the intersection point.
	for (int i = 0; i < 2; i++)
	{
		Hand hand = Input.Hand(i);
		if (!hand.IsTracked) continue;

		Ray fingerRay = hand[FingerId.Index, JointId.Tip].Pose.Ray;
		if (World.Raycast(fingerRay, out Ray at))
			Mesh.Sphere.Draw(Material.Default, Matrix.TS(at.position, 0.03f), new Color(1, 0, 0));
	}
}
