Any hook/function to check if a player is near an entity?

[Epicman3211]

Hi so I am just making a basic scripted entity and decided to make it so that if a player gets near an entity the entity will jump backwards away from the player.

So far I have the basic entity made and it can be spawned but I can't find anything on the wiki or google about my problem so here I am.

ENTITY/Think
ents.FindInSphere or ents.FindInBox or ents.FindInCone

example
function ENT:Think()

local entTbl = ents.FindInSphere( self:LocalToWorld( self:OBBCenter() ), 200 )

for i = 1, #entTbl do

print( entTbl[ i ] )

end

end
