Interface RayCastHit

Hit results of a ray-cast provided to script. See Probe.

Example

// Given an object with a BodyComponent
// If the object intersects with the ray described
// by rayStart and rayEnd, print a message.

var rayStart = new vec3(0.0, -100.0, 0.0);
var rayEnd = new vec3(0.0, 100.0, 0.0);

// Create a probe to raycast through all worlds.
var globalProbe = Physics.createGlobalProbe();
globalProbe.rayCast(rayStart, rayEnd, function (hit) {
    if (hit) {
        print("Raycast hit: " + hit.collider.getSceneObject().name);
    }
});

// Create a probe to raycast through only the implicit root world.
var rootProbe = Physics.createRootProbe();
rootProbe.rayCast(rayStart, rayEnd, function (hit) {
    if (hit) {
        print("Raycast hit all: " + hit.collider.getSceneObject().name);
    }
});
Copy

// On Tap, raycast through the scene at the tapped position and print out a message for each object hit.

// @input Component.Camera camera

var cameraTransform = script.camera.getTransform();
var camera = script.camera;

script.createEvent("TapEvent").bind(function(touchArgs) {
    var touchPos = touchArgs.getTapPosition();
    var nearPos = camera.screenSpaceToWorldSpace(touchPos, 0);
    var farPos = camera.screenSpaceToWorldSpace(touchPos, camera.far - camera.near);
    Physics.createGlobalProbe().rayCastAll(nearPos, farPos, function(hitResults) {
        print("Hit " + hitResults.length + " objects:")
        for(var i=0; i<hitResults.length; i++) {
            var hit = hitResults[i];
            print(hit.collider.getSceneObject().name + " at " + hit.position);
        }
    });
