Background colors on rarity system

leik meris said:

hat happens because the visual part of item rarity (like background colors in inventory or containers) isn’t automatic it comes from the client, not the server.

You need to modify the client (specifically the OTClient source) so it receives the rarity information from the server. For example, when the server sends an item, it should include something like getRarity or any way to indicate the item's rarity.

Then the client reads that rarity and applies the corresponding background color or image. Also, in the module that handles containers (game_containers.lua), you’ll need to add logic to update the slot color when an item with rarity is detected.

Without that, the client won’t show any visual change even if the item has rarity on the server.

Hello,

I installed the rarity system on my server (TFS 1.4.2) and it works well, the itens drop with different rarity and attributtes, but the tooltip does not read the rarity and it does not change the background colors in the inventory/containers.

I checked the others posts here in the forum with people having the same issues but what they did to fix didnt work for me.

I can be really wrong cause i started to work in a server for the first time recently and its all new to me but I think the problem is client sided, gonna leave here some files that i think it is where the problem could be.

I tried it with this other tooltip aswell that was able to read the rarity but still no background color, but for some reason this tooltip cause a bug on my server and the monsters start to have a delay when dying ( take a few seconds to change to the dead sprite) and when i die with a character it just stands there instead of showing the death message)

You're referring to tooltips, but the original question is about showing a colored background or frame depending on the item's rarity.

That feature is not present by default in OTClientV8. The client does not automatically display a visual background based on rarity that part needs to be handled manually in the src.

So while tooltips are supported, rarity-based background visuals are not included by default.

I found a post that might help you with what you're looking for:

OTClientV8 - ItemTooltip + rarity frames + custom color on item name

It explains how to add rarity frames and custom item name colors in OTClientV8 tooltips.

Hope it helps!

put the images of the boxesn in your otclient in the folder /data/images/ui ui.rar


put this function, before onContainerOpen

I had tried this link before and it did not work but i probably did something wrong, cause i tried it again now and the frames are working.

But it gives me one bug that i gonna need to find the fix when making this changes: Added tooltips for inventory items · OTCv8/forgottenserver@7f5b4fb (https://github.com/OTCv8/forgottenserver/commit/7f5b4fbc08711124dec86b0fcd7bfd78dd1165c4)

The tooltip works fine

But when i kill monsters this happens:
Gyazo Screen Video (https://gyazo.com/6718684b07ec166d03be7c523b3d8f90)
and when dying the characters just stands there

The error i got on client is this one:
ERROR: ProtocolGame parse message exception (1398 bytes, 167 unread, last opcode is 0x00 (0), prev opcode is 0xa1 (161)): InputMessage eof reached
Packet has been saved to packet.log, you can use it to find what was wrong. (Protocol: 1098)

I will mark your answer as a solution since it fixed what i asked for, now just gotta fix this errors that i got

Thanks everyone who helped here.

change

void NetworkMessage::addItem(uint16_t id, uint8_t count, bool withDescription)

to

void NetworkMessage::addItem(uint16_t id, uint8_t count, bool withDescription /* = false */)

and compile

Tell people to edit source when its not needed and they end up having character standing still after death


What do you have in packet.log?

src edits are required for what he wants to do. In older tfs versions it wasn't especially if you used otcv8 version of it but if you are using more up-to-date tfs sources you will have to modify them.

Tried this but still the same problem.


When killing monsters:
ProtocolGame parse message exception (879 bytes, 72 unread, last opcode is 0xd1 (209), prev opcode is 0x6a (106), proto: 1098): InputMessage eof reached

When dying:
ERROR: ProtocolGame parse message exception (5110 bytes, 155 unread, last opcode is 0x00 (0), prev opcode is 0xa1 (161)): InputMessage eof reached

It only happens if i make the TFS changes for the tooltip, but if I dont make those changes the client doesnt show the frames by only using the lua correctly, to make a test I changed the lua with an else white background in the end and all itens showed white in any rarity, it only get the different rarity with the tooltip working aswell.

But its probably something else that i have in the server/client that is bugging with others systems, cause the same happened when i tried to add dodge on the server, the dodge worked but the same 2 bugs show up.

I have another error on packet.log that happens right when i log in, its been there for some time but it didnt bug anything (that i found out at least) so i didnt try to fix it yet, gonna leave here just for information in case it might be related.
ERROR: ProtocolGame parse message exception (14652 bytes, 0 unread, last opcode is 0x32 (50), prev opcode is 0x32 (50)): InputMessage eof reached

Unfortunately I will be leaving in a few hours and gonna be out of city for some days, I gonna be able to work in this again just when i come back.

We're talking about otc source, theres no need to edit them for frames.
this is nonsense:

As I mentioned, needed are tfs source edits for frames to work, not client.
At client side its just 20 lines or so of code to add.

You people are unbelivable
