public static function Linecast(start: Vector3, end: Vector3, layerMask: int = DefaultRaycastLayers, queryTriggerInteraction: QueryTriggerInteraction = QueryTriggerInteraction.UseGlobal): bool;
public static bool Linecast(Vector3 start, Vector3 end, int layerMask = DefaultRaycastLayers, QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal);

Parameters

start Start point.
end End point.
layerMask A Layer mask that is used to selectively ignore colliders when casting a ray.
queryTriggerInteraction Specifies whether this query should hit Triggers.

Description

Returns true if there is any collider intersecting the line between start and end.

Parameters
