code example

First, create a capsule collider and a cube collider in the scene (as shown in the image below). Add a CharacterController component and a BoxCollider component to them respectively. Make sure to enable the "Is Trigger" property for the BoxCollider component. Set their positions to (0,0,0) and (0,2,0) respectively. Finally, attach the script to the charaterController game object.

class New_TypeScript
    extends Component {

    OnStart(): void {
        Debug.Log("OnStart");

        let charater = this.gameObject.GetComponent<CharacterController>(CharacterController);
        charater.Move(new Vector3(0,1,0));
    }

    OnTriggerEnter(collider):void{

        let ray = new Ray(new Vector3(0,0,0),new Vector3(0,1,0));
        Debug.Log(collider.Raycast(ray,10));
    }
}
