Gmod FindInSphere

[Jason138]

So I'm making a code for capturing flags and I have no clue on how to do this and just wan to know if I can get some links to other threads

What I want to do : If players enters sphere it will say in chat [Player] is capturing [Sphere] and if it gets captured (time table of like 10secs) it changes to a color and it will say in chat [Player] Captured [Sphere]

Codes right now :
cl_init.lua
[QUOTE]include('shared.lua')

function ENT:Draw()
self.BaseClass.Draw(self)

self:DrawModel()

render.SetColorMaterial()
render.DrawSphere( self:GetPos(), 350, 80, 80, Color( 0, 175, 175, 100 ) )

end[/QUOTE]

init.lua
[QUOTE]AddCSLuaFile( "cl_init.lua" ) -- Make sure clientside
AddCSLuaFile( "shared.lua" ) -- and shared scripts are sent.

include('shared.lua')

function ENT:Initialize()

self:SetModel( "models/props_docks/dock01_pole01a_128.mdl" )
self:PhysicsInit( SOLID_VPHYSICS ) -- Make us work with physics,
self:SetMoveType( MOVETYPE_VPHYSICS ) -- after all, gmod is a physics
self:SetSolid( SOLID_VPHYSICS ) -- Toolbox

local phys = self:GetPhysicsObject()
if (phys:IsValid()) then
phys:Wake()
end
end

function ENT:Use( activator, caller )
return
end

function ENT:Think()
-- We don't need to think, we are just a prop after all!
end

Shared.lua
[QUOTE]ENT.Type = "anim"
ENT.Base = "base_gmodentity"

ENT.PrintName= "A Flag"
ENT.Author= "Javs"
ENT.Contact= ""
ENT.Purpose= ""
ENT.Instructions= ""
ENT.Spawnable = true
ENT.AdminSpawnable = false[/QUOTE]

First - Wrap your code in

 or [lua] tags, not [QUOTE] tags

It doesnt have to be a sphere, no. Ill try

You can use a sphere or a box. Between two checks, use ents.FindInSphere/Box and store the return the calls. If a player exists in the old table but not the new, send the leaving message. If a player doesn't exist in the old table but exists in the new one, send the entering message.

Im not the best at coding, ive started only 1month ago, do you have any tips of how to do that

You can avoid using ents.FindIn completely by defining another entity and using StartTouch and EndTouch. Similar to how timer zones are made in bhop:

[lua]-- Taken from Flow's bhop code
function ENT:Initialize()
local BBOX = (self.max - self.min) / 2

self:SetSolid( SOLID_BBOX )
self:PhysicsInitBox( -BBOX, BBOX )
self:SetCollisionBoundsWS( self.min, self.max )

self:SetTrigger( true )
self:DrawShadow( false )
self:SetNotSolid( true )
self:SetNoDraw( false )

self.Phys = self:GetPhysicsObject()
if self.Phys and self.Phys:IsValid() then
self.Phys:Sleep()
self.Phys:EnableCollisions( false )
end
end

function ENT:StartTouch( ent )
-- Do shit
end

function ENT:EndTouch( ent )
-- Do shit
end[/lua]

Thanks <3

Doesnt work for some reason with

 PrintMessage( HUD_PRINTTALK, "I'm new here." )

Having an entity manage it is going to be more expensive overall I believe since its physics and tick simulation have to constantly be maintained over a simple loop func.
