Trying to make the Vortex Melon work for the newest version of Garry's Mod

[thefuzz1234555]

Help me please I am having issues with this LUA
AddCSLuaFile( "cl_init.lua" )
AddCSLuaFile( "shared.lua" )
include( "shared.lua" )

function ENT:Initialize()
self.Entity:SetModel( "models/props_junk/watermelon01.mdl" )
self.Entity:PhysicsInit( SOLID_VPHYSICS )
self.Entity:SetMoveType( MOVETYPE_VPHYSICS )
self.Entity:SetSolid( SOLID_VPHYSICS )

local phys = self.Entity:GetPhysicsObject()

if phys:IsValid() then
phys:Wake()
end

self.ents = {}

timer.Create("UpdateTargets"..tostring(self), 0.5, 0, self.UpdateTargets, self)
timer.Create("DoEffects"..tostring(self), 0.05, 0, self.DoEffects, self)
end

function ENT:OnRemove()
timer.Remove("UpdateTargets"..tostring(self))
timer.Remove("DoEffects"..tostring(self))
end

function ENT:DoEffects()
local allowed_classes = { "prop_physics",
"prop_ragdoll"}

for k,ent in pairs(self.ents) do
if (!ent:IsValid() || ent == vortex_melon || (!table.HasValue(allowed_classes, ent:GetClass()) && !ent:IsNPC())) then
self.ents[k] = nil
else
local rate = 5
local r,g,b,a = ent:GetColor()
local alpha = a - rate

if (alpha <= 0) then
ent:Remove()
self.ents[k] = nil
else
local ed = EffectData()
ed:SetEntity( ent )
ed:SetOrigin( self:GetPos() )
util.Effect( "particle_funnel", ed, true, true )

ent:SetColor(r, g, b, alpha)
end
end
end

end

function ENT:UpdateTargets()
local radius = 256

self.ents = ents.FindInSphere(self:GetPos(), 256 radius)
end

function ENT:SpawnFunction( ply, tr )
if ( !tr.Hit ) then return end

local SpawnPos = tr.HitPos + tr.HitNormal * 16

local ent = ents.Create( "vortex_melon" )
ent:SetPos( SpawnPos )
ent:Spawn()
ent:Activate()

return ent
end

these are the errors I get

@thefuzz1234555
You are calling ENT function by it's meta.
You need to call Method on it
Table call: self.Draw()
Method call: self:Draw()
If function is called as Method it will give self for function.
---
Also, you can create timer like that:
"UpdateTargets"..self:EntIndex()

[thefuzz1234555]

Where in the code should I put it like where its giving error lines?

[Spar]

Where you set up a callback function.
In timer.Create

[thefuzz1234555]

Hmm ok if I get another error from the code I'll comment what happend

[Spar]

Again. As a sad in first post.
You need to call function ON Entity.
So:
// BEFORE
timer.Create("UpdateTargets"..tostring(self), 0.5, 0, self.UpdateTargets, self)
timer.Create("DoEffects"..tostring(self), 0.05, 0, self.DoEffects, self)

// AFTER

timer.Create("UpdateTargets"..tostring(self), 0.5, 0, self:UpdateTargets)
timer.Create("DoEffects"..tostring(self), 0.05, 0, self:DoEffects)

[c👌de_g🎷]

That is not valid code. IT should be self.UpdateTargets and self.DoEffects

[Spar]

Yes, sorry, I understand it only now.
I say that I was right because I'm doing like that:
timer.Create("Timer",1,0,function() self:DoClick() end)

[thefuzz1234555]

I put in the new code, its not appearing in the spawn menu anymore? Please help

[c👌de_g🎷]

Check your console (server and client) for errors.

[thefuzz1234555]

Ill see if any show up when the map loads

[thefuzz1234555]

I should provide line 59
self.ents = ents.FindInSphere(self:GetPos(), 256 radius)

[c👌de_g🎷]

That code isn't valid - what is "256 radius?" Your argument should just be a number or variable alone.

[thefuzz1234555]

hmm so remove radius?

[c👌de_g🎷]

Try and see.

[thefuzz1234555]

Huh that fixed it but new error... why

Line 31: for k,ent in pairs(self.ents) do
Line 19: timer.Create("DoEffects"..tostring(self), 0.05, 0, self.DoEffects)
Line 59: self.ents = ents.FindInSphere(self:GetPos(), 256 )
Line 18: timer.Create("UpdateTargets"..tostring(self), 0.5, 0, self.UpdateTargets)

Why does this old addon have to be so broken?

[c👌de_g🎷]

"self" is not valid in the code instances provided. It will only be so if you are using self in an ENT: function.

[thefuzz1234555]

Hmm I don't know what to put @code_gs could you be more specific

[c👌de_g🎷]

Functions like this get "self" as a parameter which refers to the entity:
function ENT:SomeFunc()
Functions like this do not get a "self" parameter:
function SomeFunc()
function ENT.SomeFunc()
