Laser ray casting

A scene that shows how ray casting can be used to trace an imaginary line in space and check for object collision.

Explore the scene: this link takes you to a copy of the scene deployed to a remote server where you can interact with it just as if you were running dcl start locally.

Install the CLI

Download and install the Decentraland CLI by running the following command

npm i -g decentraland

For a more details, follow the steps in the Installation guide.

Previewing the scene

Once you've installed the CLI, download this example and navigate to its directory from your terminal or command prompt.

from the scene directory:

$:  dcl start

Any dependencies are installed and then the CLI will open the scene in a new browser tab automatically.


Notice that boxes that intersect with the laser change their material and become emissive while being hit. Also, if you point your cursor at a box it will change its color to green.
