Modifying Inventory Weight If Item Is Equipped?

Trying to do something similar to:


-snip, replaced example-

Code:

local ITEM = Clockwork.item:New();
ITEM.name = "Backpack";
ITEM.model = "models/eltaco/backpack.mdl";
ITEM.weight = 1;
ITEM.uniqueID = "backpack";
ITEM.useText = "Wear";
ITEM.category = "Storage";
ITEM.description = "A black, military styled MOLLE backpack.";
ITEM.isAttachment = true;
ITEM.attachmentBone = "ValveBiped.Bip01_Spine";
ITEM.attachmentOffsetAngles = Angle(0, 0, 0);
ITEM.attachmentOffsetVector = Vector(-3.96, 4.95, -2.97);

-- A function to get the maximum amount of weight the local player can carry.
function Clockwork.player:GetMaxWeight()
	local addInvSpace = v("addInvSpace");
	local weight = Clockwork.Client:GetSharedVar(
		"InvWeight", Clockwork.config:Get("default_inv_weight"):Get()
	);

	if (Clockwork.Client:GetSharedVar("backPack")) then
		player.addInvSpace = 4;

		for k, v in pairs(itemsList) do
			local addInvSpace = v("addInvSpace");
		
			if (addInvSpace) then
				weight = weight + addInvSpace;
			end;
		end;
	end;
end;

-- Called when the attachment offset info should be adjusted.
function ITEM:AdjustAttachmentOffsetInfo(player, entity, info)
	if (string.find(player:GetModel(), "female")) then
		info.offsetVector = Vector(0, 3, 1.75);
	end;
end;

-- A function to get whether the attachment is visible.
function ITEM:GetAttachmentVisible(player, entity)
	if (player:GetSharedVar("backPack")) then
		return true;
	end;
end;

-- Called when the item's local amount is needed.
function ITEM:GetLocalAmount(amount)
	if (Clockwork.Client:GetSharedVar("backPack")) then
		return amount - 1;
	else
		return amount;
	end;
end;

-- Called to get whether a player has the item equipped.
function ITEM:HasPlayerEquipped(player, arguments)
	return player:GetSharedVar("backPack");
end;

-- Called when a player has unequipped the item.
function ITEM:OnPlayerUnequipped(player, arguments)
	local skullMaskGear = Clockwork.player:GetGear(player, "BackPack");
		
	if (player:GetSharedVar("backPack") and IsValid(skullMaskGear)) then
		player:SetCharacterData("backpack", nil);
		player:SetSharedVar("backPack", false);
			
		if (IsValid(skullMaskGear)) then
			skullMaskGear:Remove();
		end;
	end;
		
	player:GiveItem(Clockwork.item:CreateInstance(self.uniqueID));
end;

-- Called when a player drops the item.
function ITEM:OnDrop(player, position)
	if (player:GetSharedVar("backPack") and #player:GetItemsByID(self.uniqueID) == 1) then
		Clockwork.player:Notify(player, "You cannot drop this while you are wearing it!");
			
		return false;
	end;
end;

-- Called when a player uses the item.
function ITEM:OnUse(player, itemEntity)
	if (player:Alive() and !player:IsRagdolled()) then
		Clockwork.player:CreateGear(player, "BackPack", self);
			
		player:SetCharacterData("backpack", true);
		player:SetSharedVar("backPack", true);
		player:GiveItem(Clockwork.item:CreateInstance(self.uniqueID));
			
		if (itemEntity) then
			return true;
		end;
	else
		Clockwork.player:Notify(player, "You don't have permission to do this right now!");
	end;
	
	return false;
end;

ITEM:Register();

Trying to get it to call if a backpack is being worn in the equipment tab, to add additional inventory weight.

Any suggestions on how to do it?

 

You provided incomplete code.

 

Sorry, I was messing around with stuff.

Here's the full item.

Code:

local ITEM = Clockwork.item:New();
ITEM.name = "Backpack";
ITEM.model = "models/eltaco/backpack.mdl";
ITEM.weight = 1;
ITEM.uniqueID = "backpack";
ITEM.useText = "Wear";
ITEM.category = "Storage";
ITEM.description = "A black, military styled MOLLE backpack.";
ITEM.isAttachment = true;
ITEM.attachmentBone = "ValveBiped.Bip01_Spine";
ITEM.attachmentOffsetAngles = Angle(0, 0, 0);
ITEM.attachmentOffsetVector = Vector(-3.96, 4.95, -2.97);

-- A function to get the maximum amount of weight the local player can carry.
function Clockwork.player:GetMaxWeight()
	local addInvSpace = v("addInvSpace");
	local weight = Clockwork.Client:GetSharedVar(
		"InvWeight", Clockwork.config:Get("default_inv_weight"):Get()
	);

	if (Clockwork.Client:GetSharedVar("backPack")) then
		player.addInvSpace = 4;

		for k, v in pairs(itemsList) do
			local addInvSpace = v("addInvSpace");
		
			if (addInvSpace) then
				weight = weight + addInvSpace;
			end;
		end;
	end;
end;

-- Called when the attachment offset info should be adjusted.
function ITEM:AdjustAttachmentOffsetInfo(player, entity, info)
	if (string.find(player:GetModel(), "female")) then
		info.offsetVector = Vector(0, 3, 1.75);
	end;
end;

-- A function to get whether the attachment is visible.
function ITEM:GetAttachmentVisible(player, entity)
	if (player:GetSharedVar("backPack")) then
		return true;
	end;
end;

-- Called when the item's local amount is needed.
function ITEM:GetLocalAmount(amount)
	if (Clockwork.Client:GetSharedVar("backPack")) then
		return amount - 1;
	else
		return amount;
	end;
end;

-- Called to get whether a player has the item equipped.
function ITEM:HasPlayerEquipped(player, arguments)
	return player:GetSharedVar("backPack");
end;

-- Called when a player has unequipped the item.
function ITEM:OnPlayerUnequipped(player, arguments)
	local skullMaskGear = Clockwork.player:GetGear(player, "BackPack");
		
	if (player:GetSharedVar("backPack") and IsValid(skullMaskGear)) then
		player:SetCharacterData("backpack", nil);
		player:SetSharedVar("backPack", false);
			
		if (IsValid(skullMaskGear)) then
			skullMaskGear:Remove();
		end;
	end;
		
	player:GiveItem(Clockwork.item:CreateInstance(self.uniqueID));
end;

-- Called when a player drops the item.
function ITEM:OnDrop(player, position)
	if (player:GetSharedVar("backPack") and #player:GetItemsByID(self.uniqueID) == 1) then
		Clockwork.player:Notify(player, "You cannot drop this while you are wearing it!");
			
		return false;
	end;
end;

-- Called when a player uses the item.
function ITEM:OnUse(player, itemEntity)
	if (player:Alive() and !player:IsRagdolled()) then
		Clockwork.player:CreateGear(player, "BackPack", self);
			
		player:SetCharacterData("backpack", true);
		player:SetSharedVar("backPack", true);
		player:GiveItem(Clockwork.item:CreateInstance(self.uniqueID));
			
		if (itemEntity) then
			return true;
		end;
	else
		Clockwork.player:Notify(player, "You don't have permission to do this right now!");
	end;
	
	return false;
end;

ITEM:Register();

 

Also, currently results in:

[Clockwork] The 'ScoreboardShow' hook failed to run.
gamemodes/outlands/schema/items/sh_storage_backpack.lua:21: attempt to call global 'v' (a nil value)

When you attempt to open the tab menu.

 

v Isn't defined for 'local addInvSpace = v("addInvSpace");'

 

He made a new post.

 

Eh?

 

I looked through both of the max weight functions. Where would v be defined?

cl_player:

Code:

-- A function to get the maximum amount of weight the local player can carry.
function Clockwork.player:GetMaxWeight()
	local itemsList = Clockwork.inventory:GetAsItemsList(
		Clockwork.inventory:GetClient()
	);
	local weight = Clockwork.Client:GetSharedVar(
		"InvWeight", Clockwork.config:Get("default_inv_weight"):Get()
	);
	
	for k, v in pairs(itemsList) do
		local addInvSpace = v("addInvSpace");
		
		if (addInvSpace) then
			weight = weight + addInvSpace;
		end;
	end;
	
	return weight;
end;

sh_kernel:

Code:

-- A function to get the maximum weight a player can carry.
function playerMeta:GetMaxWeight()
	local itemsList = Clockwork.inventory:GetAsItemsList(self:GetInventory()); 
	local weight = self:GetSharedVar("InvWeight");
	
	for k, v in pairs(itemsList) do
		local addInvSpace = v("addInvSpace");
		if (addInvSpace) then
			weight = weight + addInvSpace;
		end;
	end;
	
	return weight;
end;

 

It's defined a few lines down. Just delete the first instance of local addInvSpace = v("addInvSpace");

 

So I tried out the code you sent, but you were missing a do on line 30, so I added one in. When I equipped the backpack, the server started experiencing a god-awful lag, and I checked the server's console and found this:

http://4stor.com/3inXS

However, it does seem to increase weight when worn. It just nearly crashes the server as a side effect. \o/

I was having this same problem when trying to work on this earlier, using something along the lines of "if item is equipped then ITEM:addInvWeight 4;" or something similar.
