[ H3LP ] Check entity in origin distance

Hello. How can I check the closest entity in an origin distance? Like if I use vector_distance from point1 to point2, I wanna get the closest entity from that vector distance.

Re: [ H3LP ] Check entity in origin distance

Loop through all entities in this distance and keep only the closest one in variable.

Use Find entity in sphere and check who got the closest distance

I used find entity in sphere, but I don't know how to get them in a line from fOrigin to fRet. So this acts like a TraceLine, and I only want to look at entities from that line. If I user vector_distance the normal way it won't work as I want to. I can try getting all entities origin, and check if there is a close distance between the entity origin and fRet, but, wouldn't that check it in a sphere? Like it can return a wrong entity.

      pev(ent, pev_origin, origin_2)

}

Origin_1 is where your point 1 is located
