Line of Sight

[sandbox_4]

Hello I need to know if theres something in the direct path between 2 entities. For example

[entity1] [entity2]

in this case theres nothing in the direct path between the entities so i need a function like entity1.line_of_sight? entity2 true

but in this case

[entity1] [cube] [entity2]

theres a cube in the direct path so the direct path is obstructed then
entity1.line_of_sight? entity2 false

thank you
