The Trace property of the PhysicsWorld class provides a PhysicsTraceBuilder that allows you to perform ray tracing operations within the physics world. Ray tracing is a technique used to determine the path of rays through a scene, which can be useful for collision detection, visibility checks, and other physics-related queries.
To use the Trace property, you can access it directly from an instance of PhysicsWorld. The PhysicsTraceBuilder returned by this property can be configured to specify the start and end points of the trace, as well as any additional parameters such as collision filters or trace masks. Once configured, you can execute the trace to obtain results about any intersections or collisions that occur along the trace path.
// Example of using the Trace property to perform a ray trace
PhysicsWorld physicsWorld = new PhysicsWorld();
PhysicsTraceBuilder traceBuilder = physicsWorld.Trace;
// Configure the trace
traceBuilder.Start = new Vector3(0, 0, 0);
traceBuilder.End = new Vector3(10, 0, 0);
// Execute the trace
PhysicsTraceResult result = traceBuilder.Run();
// Check if the trace hit anything
if (result.Hit)
{
// Handle the hit result
var hitPosition = result.Position;
var hitNormal = result.Normal;
// Additional logic here
}
