Proximity Detection

[MattJeanes]

So basically, I'm creating some sort of creeper and I need a way to detect how close the player is to the Entity.

Once it detects the player close enough, I've got creeper sounds and an env_explosion and removing itself to top it all off.

Two ways:
[lua]
for k, v in pairs(ents.GetAll()) do
if v:GetPos():Distance(self:GetPos()) <= 50 then
if v:IsValid() and v:IsPlayer() or v:IsNPC() then
--Explode shit here
end
end
end
[/lua]

Or
[lua]
for k, v in pairs(ents.FindInSphere(self:GetPos(), 50) do
if v:IsValid() and v:IsPlayer() or v:IsNPC() then
--Explode shit here
end
end
[/lua]

Something like that. May have to tweak them to fit your needs exactly but those are the two basic ways.
