Seems to be overriding the default gamemode PlayerSpawn... How would you fix this?

[QUOTE=meharryp;47833479]What's the difference? I've always used pairs and never had any problems.[/QUOTE]

ipairs forces the iteration to be sequential if the keys are numerical and sequential.

[Willox]

pairs will - by implementation - iterate numeric indexes in order first, but it's undefined and not guaranteed to happen.

function GM:PlayerInitialSpawn(ply)

GAMEMODE:PlayerSpawnAsSpectator( ply )

end

This code, for some reason, doesn't spawn the player as a spectator. I need this to work, though, because I want to do it the first time a player spawns... Am I using the wrong hook? Did I do something wrong? I need help...

[editline]Edited:[/editline]

I found out that PlayerInitialSpawn() is called when the player is still loading into the game, so what hook would I use that is called whenever a player has spawned but is called only the first time the player spawns?

[toshko3331]

What should I used to hook onto when the server starts? I want to initialize my game mode timer as the server is just beginning. My idea is 'InitPostEntity' but I'm not sure if this is correct. Can someone tell me if I should use this or is there a better way to go about it?

Perhaps you could hook onto PlayerSpawn() and when that is called your function can do a conditional check weather it is first spawn or not. You can do that check by using some sort of a Boolean variable. This is my idea, what do others think?

How do you get details from a map. Say if a player is in a custom zone.

If the map has a "bitches only" zone then how would you find if ply is in zone "bitches only"?[/QUOTE]

Can someone inform me of all the related files and folders for nextbots so I can copy them over into a gamemode that derives from base?

[Lolcats]

Nextbots work in Base gamemode. It's a problem with your code.

You also might not have your navmesh generated. Set sv_cheats to 1, and enter nav_generate.

Thank you for the source.

I created this map, and yea the problem was with the navigation mesh. These are normally created via hammer right?

Also I know there is a navigation mesh module around here somewhere, is this any more efficient(quicker) than the standard one created via hammer?

I think I know why you're getting numbers so close to, or equal to, 0

[quote=The Wiki]this will return at what distance the trace left the solid from [B]0-1[/B][/quote]

By having your trace 10000 units long, that means if it only takes 15 units to exit the object, you'll get 0.0015 - if it takes 5 units, you'll get 0.0005
When it says from 0 to 1, 0 = it starts out in free space, 1 = it reached the end of the trace and never left the object. This is considerable when your trace is only 20 units long, but with a trace 10k units long, 100 units is just 0.01, 8 feet (or about 2.44 meters) is just 0.0128

[B]Here's a solution:[/B] Take what you get, and multiply it by 10000. This would give you the exact unit distance from Entity(blah):GetPos() to free space. I do recommend dropping that number down significantly though, perhaps to just 500... which should still be WAY more than enough to trace out of any prop / object you throw at it.

if you want a zone in a map, you could create a custom entity folder like below then create a brush and force it to that entity by typing it in the box.

ENT.Base = "base_brush"
ENT.Type = "brush"
 
function ENT:StartTouch( entity )
	if(entity:IsPlayer() and entity:IsValid() then
		for _, v in pairs(player.GetAll()) do
			v:PrintMessage(HUD_PRINTTALK, entity:GetName().. " has entered the lua brush area.")
		end
	end
end

alternatively you could probably just name a brush, use ents.FindByName to get it, use :StartTouch like above to create the callback when an entity touches it, and :SetTrigger(true) to enable it.

Hey, how can I get some particles to stay locked to the viewmodel? It looks really weird while moving right now, and I'm using ParticleEffectAttach already.

How can I keep dynamically created materials from dying when doing anything that invokes a material reload? (mat_reload, changing some video settings, etc) Preferably without checking its validity every frame?

[A Fghtr Pilot]

I need to know what the best way to display a serverside variable in clientside HUDPaint hook is.

In a deathmatch gamemode I'm creating I need to display the amount of kills a certain team has... problem is, the variable that shows these kills is serverside.... would I create a shared variable that's value is the serverside variable and use the shared variable in my cl_init script or would I send a net message from the client to the server, containing this variable or vice versa(that might not be a good idea to send a net message every frame, or would it be?), or would I just need to do something else I haven't thought of yet?

I want to give a player a certain item in pointshop if they kill somebody with fire. Any help?

		attacker:PS_GiveItem( "melon" )
	end

[QUOTE=thegrb93;47840588]I know how to do math on a fraction. The problem is FractionLeftSolid is returning 0.[/QUOTE]

Then try dropping the length of the trace. In theory FractionLeftSolid should then be a larger decimal, that MIGHT fix it. Also, I'm sure you've already done this, but make sure you're not rounding it somehow.

Yes I'm sure that 200 is enough to exit the prop. Should return 1 anyway though if it doesn't exit the solid.

[QUOTE=toshko3331;47843844]Quick question, is the GAMEMODE table available client side?[/QUOTE]

yes

[toshko3331]

[QUOTE=Willox;47843845]yes[/QUOTE]

In that case I have some sort of a strange problem. I have a round timer thingie, and there are different states for it. I set the state of it in the GM:Initialize function as such 'GAMEMODE.state = WARMUP' (WARMUP is a constant). I have printed the value in the init.lua and shared.lua and it is fine. However, when I try to access it in the cl_init.lua it comes up nil. I access it by doing this

function GM:PlayerTick()
	print("         " .. self:GetGameState())
	--ROUND:GetRemainingTime()
end

Actually , as a matter of fact, anything that I try to access outside of this client returns nil such as my 'ROUND:GetRemainingTime()' which is located in a different file and is supposed to return a floating point number.
