Standalone [1.3] tModLoader - A Modding API

[Elemental Δ]

Hello folks,

Is there any way to resize the UI?
View attachment 350231

I am running the game at 4k resolution.

There should be something in the interface tab, unless you've already messed with that.

 

[Lord_BashALot]

Weird, I have checked the interface tab and see nothing that can change the size of the UI.

It should be in the general tab, actually.

Yup, it works. Thanks for the help.

Edit:
After playing for a while, it seems the item 'Celebration Mk2' is not available in the game?

According to the wiki, that item was introduced in patch 1.4.0.1

you are on 1.3 yes

Alright, so:

I'm trying to get into modding, and without even modifying the newly-created mod file, this error message pops up when I try to reload+build. None of the tutorials I've watched have accounted for this issue, and I've looked online with many keywords to try and find a solve, but still can't find anything.

I've checked tModLoader's files and my mod's files for something named "Object", tried renaming the "obj" file in my mod file to "Object", and none of it has worked. I'm stumped.

Very sorry if this is a frequently asked question, I'm just confused as to what to do to solve this.

I don't know... really anything about C#, but judging by the error message, it looks like you need to reference a file. I have no idea how to do that, though, so my advice would be ask the Discord for help. Just tell them what you posted here in the modding-help channel, and you might be able to get someone who knows what they're doing pretty quickly.

Are you using Visual Studio 2022? If so, try uninstalling that, deleting its installer, and getting the 2019 version here. I had the same problem when I started a few days ago and doing this fixed it.

So, how much time left until we get tModLoader updated to 1.4?? The Journey's End update came almost 2 years ago and we still have nothing from tModLoader. And, no, tModLoader in alpha version is not valid here because it is laggy. I'm getting tired of waiting.

I can kinda understand, dude, I really want TModLoader to bw updated to 1.4 and its updates, cause as much as I love vanilla, I like using mods to add stuff or improve quality of life, like the Better Taxes mod, Nooby's OverPowered Mod cause it has a really powerful terrain destroying rocket launcher, or even Spirit, Tremor, and Calamity, but I'm hoping it wont be too much longer now.

11.8.6 tmodoader was released today on github and steam, what can be done to get 64bit updated? Thank you.

Hello everybody,
I've just got into modding Terraria, and I'm coming across something I have no idea how to do. It's a bit ambitious, but any help would be appreciated. I'm trying to create a custom resource, similar to mana. Also, by "consuming" this custom resource, your character will gain buffs with animated visual effects, such as lightning around your feet for a speed boost, an increase in character size for a health boost, a glowing red outline for a damage boost, etc. Does anybody know how I would go about doing this? I am a bit new to coding, so I may be in over my head here, but any help would be greatly appreciated!

It is most definitely not the easiest thing for someone completely new to coding. The most basic tmodloader functions revolve around making basic items or npcs. What you are trying to make involves running a global player script that holds a variable for your resource which is then referenced in every script that uses said resource. Depending on how you want these buffs to activate you might need to catch player inputs in update methods and whatnot. It isn't the most complicated thing in the world but it requires a bit of knowledge of how object oriented programing works and it depends on how versed you are on the fundamentals of coding.

I only have a few months of coding experience, but I would really like to give it a try... do you have any idea how I would go about starting to code this? And if not, do you know how I could incorporate animated sprites to my buffs, as mentioned above? Thank you!

Here's all my code:

That is quite a lot of good progress. I'd suggest to either upload the codes to hastebin or use the forum's "Insert Code" command to make things more readable.

I can't really spend much time on it atm, and tMod's UI coding is something I'm a bit behind with myself as I haven't done much of it. First thing I'd try is debug and make sure the UI can at least draw anything at all to bar any problems with the logic, for instance I'd remove the condition in Draw to make sure it always draws, and simplify the drawing logic with something that easily verifies the method is being called at all (like drawing some gibberish on screen or debug text).

ok so i play on pc a friend LEGALLY gave me his terraria version from gog and when i tried to run mod loader this came up:

Looking for help, when playing t-modloader with a bunch of mods (Calamity, Stars Above, Split, AlchemistNPC, Fargos's Soulsmod, and more i cannot remember atm, will give them if needed.) my game crashes whenever the first wave of the Old Ones Army starts. Same thing happens if i just spawn an Ogre. My game also crashes as the Warrior of Light boss from Stars Above would go into his final phase.

The log file is needed to figure this out (My Games/Terraria/ModLoader/Logs/client.log), but honestly you'll more likely be able to solve this by asking on our discord (tModLoader.net/discord), that's where most support inquiries are resolved. Very rarely will someone able to actually help you check this thread.

Hey, I wonder:
Any chance of getting hook for health regen and damage? Like, natural, buff and debuff damages?
