//Create two GameObjects (e.g. a Cube) and place them near each other. Attach this script to one of them.
//Click on the GameObject with the script. Attach the other GameObject to the “My Game Object” field in the Inspector.
//Make sure both have Collider components
//Choose your own “Max Distance” in the Inspector (e.g. 600).

//This script casts a ray that ignores Trigger Colliders. //Press space to switch the second GameObject between a Trigger and non-Trigger GameObject. When the Trigger is off, the ray detects a collision. When it is on, no collisions occur.
