Cl_init slider changing information failing?

[Monkey471]

Code:

 local DermaSlider = vgui.Create( "DNumSlider", base )
DermaSlider:SetPos( 0, 65 ) 
DermaSlider:SetWide( 250 )
DermaSlider:SetMin( 0 )
DermaSlider:SetSize( 300,20 )
DermaSlider:SetMax( 1000 )
DermaSlider:SetValue( v:GetJumpPower() )
DermaSlider:SetDecimals( 0 )
DermaSlider.OnValueChanged = function( panel, value )
local data = math.Round(value)
print(v:GetJumpPower().." -> "..tostring( data ) )
print(v:GetJumpPower())
v:SetJumpPower( tonumber(data) )
v:PrintMessage( HUD_PRINTTALK, "Stats edited." )
		end

debug messages:

Stats edited.
705 -> 705
705
Stats edited.

v does return the correct player as i do recieve the message: "Stats edited." however my jump power does not change, also the slider will often set its self to 500 when my jump is not that. Please help.

I feel as if this is a problem with not being able to edit the player in client side files,

if so, how would i send a message to trigger a function in init.lua?
if not, what is the problem?

You're calling a server-side function client-side.

You need to send that data to the server, and let the server set the jump-power.

use something like

[lua]// client
net.Start( "NetMessage" );
net.WriteLong( _jump_power );
net.SendToServer( );

// Server
util.AddNetworkString( "NetMessage" );
net.Receive( "NetMessage", function( bytes, Player )
local _jump_power = net.ReadLong( );
print( "Before: " .. Player:GetJumpPower( ) );
Player:SetJumpPower( _jump_power );
print( "After: " .. Player:GetJumpPower( ) );
end );[/lua]

I have tried this before but only got the same type of error as i am recieveing now:

[ERROR] gamemodes/example/gamemode/cl_init.lua:41: attempt to call field 'WriteLong' (a nil value)

with the code:

net.WriteLong( data )

data: local data = math.Round(value)

value: DermaSlider.OnValueChanged = function( panel, value )

Full error log:

[ERROR] gamemodes/example/gamemode/cl_init.lua:41: attempt to call field 'WriteLong' (a nil value)
  1. OnValueChanged - gamemodes/example/gamemode/cl_init.lua:41

WriteLong must've been changed for something else... Try WriteDouble and ReadDouble -- Int goes to 255, and you have to write the number of bytes going out, and know what's coming in. So, replace those and it should be fine.

Thanks, the message was received however i now get this:

[ERROR] gamemodes/example/gamemode/init.lua:80: attempt to call method 'SetJumpPower' (a nil value)
1. func - gamemodes/example/gamemode/init.lua:80

code:
local ply = net.ReadEntity()
local data = net.ReadDouble()
ply:SetJumpPower(tonumber(data))

net.ReadEntity() = ply from : hook.Add( 'ShowSpare2', 'openf4menu', function( ply ) ... end)

How does it get this:

net.ReadEntity() = v

v = net.ReadEntity()

net.ReadEntity() = net.WriteEntity( ply )

ply = ply from : hook.Add( 'ShowSpare2', 'openf4menu', function( ply ) ... end)

Meaning your ply entity is null. You don't need to write entity if it's coming from the player you're changing. I showed you in the code, on net receive there is bytes and Player passed in automatically... Use that Player..
