| position | Center of the sphere. |
| radius | Radius of the sphere. |
| layerMask | A Layer mask that is used to selectively ignore colliders when casting a ray. |
| queryTriggerInteraction | Specifies whether this query should hit Triggers. |
Returns an array with all colliders touching or inside the sphere.
NOTE: Currently this only checks against the bounding volumes of the colliders not against the actual colliders.
