2 Problems with 1 Variable

[ZerK]

I have a variable set which decreases by 1 every second. I also have an entity which when it makes contact with another entity, disappears and adds 17 to the variable. However, the variable doesn't add it properly. It adds it 2-3 times.

Also, when I try to take a variable from init.lua and put it into cl_init.lua (I tried doing it with and without networking), it doesn't read the variable. It gives an error when I have it set to display on a world tip and when I use tostring on it.

And finally, "if var < 1" doesn't register. It keeps going under 1 into the negatives.

[lua] var = 100
timer.Create("Timer", 1, 0, function()
var = var - 1
for k,v in pairs(player.GetAll()) do
v:PrintMessage(HUD_PRINTTALK, var)
end
end)
if var < 1 then
self:Remove()
timer.Destroy("T")
end[/lua]

[LUA] if hitEnt:GetClass() == "test_entity" and self:GetNWBool("Bool") == false then
hitEnt:Remove()
var = var + 17
timer.Destroy("Timer")
for k,v in pairs(player.GetAll()) do
v:PrintMessage(HUD_PRINTTALK, var)
end
end[/LUA]

[lua] if self:BeingLookedAtByLocalPlayer() then
AddWorldTip(self:EntIndex(), "Test\nOwner: "..LocalPlayer():Nick().."\nVar: "..var, 0.5, self:GetPos(), self)
end[/lua]

The error it gives me when I look at the entity:

[lua][ERROR] addons/addon/lua/entities/test/cl_init.lua:13: attempt to concatenate global 'var' (a nil value)
1. unknown - addons/addon/lua/entities/test/cl_init.lua:13

init.lua is SERVERside while cl_init.lua is CLIENTside. Creating a var, even if it was a global, wouldn't work like that...

Put it in the SHARED file if you want to do that; but even then, the client and server "connect" at different times, so you'd need to send a net-message to all connecting players to let them know where the var was currently...

You could also use NWVar ( They can cause issues, so I'd recommend caching, check for a new number every half a second to second since it won't change more often than that )

Not good tests but some shows that nwvar can be costly: [url]https://dl.dropboxusercontent.com/u/26074909/tutoring/benchmarking_tips/benchmarking_nw_vars.lua.html[/url]

Didn't work :L same error

init
[lua] util.AddNetworkString("Net")
net.Start("Net")
net.WriteString(var)
net.Broadcast()[/lua]

cl_init
[lua] net.Receive("Net", function(len)
var = net.ReadString()
end)[/lua]

EDIT: I spawned the entities again and the var is changing but the displayed var is still stuck at 100.

I wrote up a quick tutorial for count-down:
