Problems That Don't Need Their Own Thread v2.0

hey how can you tell what type of material you are looking at? Basically if I get the material that the player is looking at it should tell me if it is wood,dirt, or metal

[TheWindow]

Is there any way to make a reliable continuous use entity? I need it to run a function after the player holds the key down for ~4 seconds. I've come up with a cheap way of doing it with a boolean that checks on the think hook, but there has to be a better way of doing it.

Figured out a pretty good way to do this.

function ENT:Think()
	if !IsValid(self.User) then return end
	if (!self.User:KeyDownLast(IN_USE) or self.User:GetVelocity():Length() > 100) and self.BeingUsed then
		self.BeingUsed = false
		self.User:ChatPrint(tostring(self.BeingUsed))
		self.UseAmount = 0
	elseif (self.BeingUsed) then
		self.UseAmount = self.UseAmount+1
		self.User:ChatPrint(tostring(self.UseAmount))
	end
end

function ENT:AcceptInput( name, activator, caller )
    if name == "Use" and caller:IsPlayer() and !caller:KeyDownLast(IN_USE) then
		self.BeingUsed = true
		self.User = activator
		self.UserPos = activator:GetPos()
		self.UseAmount = 0
        activator:ChatPrint(tostring(self.BeingUsed))
    end

If you're just calling a serverside gamemode function it should be as easy as throwing in SomeFunction(arguments) into the serverside hook you need.

i have a question, can i use 2 if statement on the same line? like
if ply:SteamID() then
if ply:IsUserGroup("VIP") then
etc.

[Mista Tea]

I'm having some incredibly annoying issues with the way presumably Garry coded the gmod_tool STool.

Basically, imagine there are 2 players on the server that are using the same tool. This tool has stuff that gets called in TOOL:Init() that is meant to be run [B]once per client[/B]. For example, adding a hook on the client that requires TOOL's [B]self[/B]. It's fine that TOOL:Init() gets called again when the player dies and respawns -- I get that.

The problem, however, is that not only does TOOL:Init() get called when your specific client respawns, it gets called [B]when other clients respawn as well[/B]. It's the same thing with TOOL:Holster and (probably) TOOL:Deploy.

Essentially, other players are able to fuck up my current tool's state because every time someone else respawns or holsters/deploys their toolgun, it calls the corresponding function on my client as well.

The simplest way to see this is to add any print statement inside TOOL:Init() and have other players kill themselves. Every time [B]they[/B] respawn, TOOL:Init() will be called on [B]your[/B] client.

Is there seriously a reason the gmod_tool was coded like this, and is there anything I can do about it that doesn't require editing it?

[QUOTE=Robotboy655;45483863]You will have to post your questions/problem if you want help.[/QUOTE]
Well since NextBot is an abomination if you wanna do anything other than monsters / melee NPCs and I much prefer having the good old regular bots drive my vehicles I've hit a snag with path finding. Rather than reinventing the wheel for the millionth time I'd rather try and use the NavMash library. The problem is it crashes ALOT so I can't quite figure out in what order I have to do things and how frequent I can actually call the methods without impacting performance. Basically the bots are regular good old bots, engine treats them like player objects which works awesomely well with my vehicle system meaning I don't have to do any changes to my vehicle base in order to let AI use them. Everything from finding a tank in LOS, entering it, starting it up and finding targets works just fine. The problem is I need to find the closest safe vector for the bot to move to when the variable/field "Target" exists on the bot.

Did some testing last night

    local ply = player.GetAll()[1]
    local pos = ply:GetEyeTrace().HitPos
    local NavAreas = navmesh.GetNavArea( ply:GetPos(), 1000 )
    NavAreas:Draw() -- this turns up as a big flat surface ontop of the ground
    NavAreas:DrawSpots() -- this doesnt seem to do anything (tested on gm_flatgrass)
        print( NavAreas:GetClosestPointOnArea( pos ) )  --and this crashes the game if you call it too often?

Just as an example, but this seems to crash my game. What's a safe method to continuously find the closest safe vector for the bot + tank to move to? I already have the moving part figured out it's just that I need to get the closest safe vector leading up to the bots target rather than just checking if we can see the target and then move.

[Rubat]

Have you generated a nav mesh for the map?
You could also look at how nextbot calls those functions.

[QUOTE=Robotboy655;45483964]Have you generated a nav mesh for the map?

I did look at nextbot and it refers to loco all over the place. Wasn't too helpful. I started out by generating the navmesh before i tested the above code. It crashes alot.

Edit:

I don't need the player movement to work. I just need a proper and non resource intensive method to find the closest safe vector.

I don't think so.. Or I can't understand hooking...

function CallSetObjective( objective )
	print( "Your objective is: "..objective)
	// Need to call SetObjective() function from init.lua
end


function ENT:AcceptInput( name, activator, caller, data ) 

	if ( name == "SetObjective" ) then CallSetObjective( data ) return true end
	
	return false
	
end

this is some code in [B]some_entity.lua[/B]

and I want to call a function [B]SetObjective()[/B] from [B]init.lua[/B], and I have no idea how to do it.
And this function needs to be called with argument!

[B] OKEY IT'S SOLVED [/B]
used:
hook.Add in init.lua and hooked onto SetObjective() function
hook.Call in some_entity.lua and called added hook

How badly did I murder this? I am attempting to load a pac outfit using pointshop. (Default Pointshop)
I dont want to disable anything until I can get the pac part working, and I dont know how to reference pac right.

ITEM.Name = 'PacExample'
ITEM.Price = 1000
ITEM.Model = 'models/xqm/jetengine.mdl' --not really used
ITEM.Bone = 'ValveBiped.Bip01_Spine2' --not really used

function ITEM:OnEquip(ply, modifications)
	local outfit = pac.luadata.ReadFile("pac3/mech.txt")
	ply:PS_AddClientsideModel(self.ID)
	self:AttachPACPart(outfit)
		pac.SetupENT(ENT) -- this can also be used in initialize using "self" instead of "ENT" Can I change this to ply?
end



function ITEM:OnHolster(ply)
	ply:PS_RemoveClientsideModel(self.ID)
        self:RemovePACPart(outfit)
end

function ITEM:ModifyClientsideModel(ply, model, pos, ang) -- Left over
	model:SetModelScale(0.5, 0)
	pos = pos + (ang:Right() * 7) + (ang:Forward() * 6)
	
	return model, pos, ang
end

function ITEM:Think(ply, modifications) -- Left over stuff from Jump Pack
	if ply:KeyDown(IN_JUMP) then
		ply:SetVelocity(ply:GetUp() * 6)
	end

[/QUOTE]

you're using net.Receive when you should be using net.ReadString, and net variables can only be read once (the print will be wrong).

also, if you plan on releasing this (or even just using this), don't use Write/ReadTable, you can easily make functions for those tables

[lua]
function net.WriteVoteInfo(t)
net.WriteUInt(#t - 1, 5) --this goes up to 32 items

for k, v in pairs(t) do
net.WriteString(v.name)
net.WriteUInt(v.votes, 6) --this goes up to 63 votes
end
end

function net.ReadVoteInfo()
local ret = {}

local len = net.ReadUInt(5) + 1

for i = 1, len do
local name = net.ReadString()
local votes = net.ReadUInt(6)

table.insert(ret, {name = name, votes = votes})
end

return ret
end[/lua]
