October's Stable TML release is here with new API features & modernization, polishing, and a wagon of stability improvements.

tModLoader for Terraria v1.4.4, when?

Before we begin, we hope everyone has been having fun playing the new Terraria v1.4.4 update (Labor of Love). We know everyone is looking forward to mods having access to all of the new features. We'd like to remind tModLoader users that updating tModLoader to the v1.4.4 codebase will take some time, so please be patient.

We are committed to getting tModLoader updated to v1.4.4 sometime soon, but we can not guarantee when that will be. Much of the Terraria code has changed and we will need time to adapt tModLoader to those changes and then give mod makers time to adapt their mods to those changes. If you are a mod maker and are interested in the migration to 1.4.4, please participate in our Discord development channels and on GitHub.

New Changes' Highlights

The following is a list of the most noteworthy pull requests and commits that have been pushed to 1.4-preview in September, and are now available on the default/stable branch.

Improve dedicated server management utils. (#2817) by pollen__

• Adds Docker support and a server management script to help with setting up dedicated Linux servers
• The DedicatedServerUtils folder in your tModLoader install will contain files you can copy to a server, and the scripts will download tML and let you manage versions and mod updates
• Read DedicatedServerUtils readme

Custom Game Tips by MutantWafflez

• Custom game tips are now autoloaded from translation files when the key starts with "Mods.YourModName.GameTips".
• Vanilla and modded game tips can be hidden by calling GameTipData.Hide() in the new ModSystem.ModifyGameTipVisibility(IReadOnlyList<GameTipData>) hook
• See ExampleGameTipSystem and the en-US.hjson file in ExampleMod for more details

Raise minimum graphics profile to HiDef by Chicken-Bones

• HiDef vs Reach are the two graphics profiles offered by FNA. HiDef allows for better graphics features (bigger textures, better visuals) and is supported by basically every graphics card since 2010.
• HiDef was the default in tML 1.3, but this was lost in the port.
• There is no fall-back implemented. If your graphics card is really really old. Sorry. If you have a newer graphics card and are experiencing crashes due to this change, please let us know and we will investigate.

Example Jousting Lance by Rijam

• Adds ExampleJoustingLance and ExampleJoustingLanceProjectile
• Adds ProjectileID.Sets.NoMeleeSpeedVelocityScaling to disable melee speed projectile shoot velocity scaling (used by jousting lances and the monk staff T2 and T3 projectiles)
• Adds Item.InterruptChannelOnHurt and Item.StopAnimationOnHurt

GlobalNPC.Send/ReceiveExtraAI() by Antirhinnum

• A direct clone of the same hooks for GlobalProjectile
• Allows you to sync extra data with NPCs from globals without hijacking the SyncNPC packet.
• Please be careful and judicious with network overhead, every byte counts, make sure to use GlobalNPC.AppliesToEntity to filter out NPCs that don't need your extra data

Eight missing patron sets from 1.3 by Mirsario

• Eight missing patron sets from 1.3 were restored to 1.4 tModLoader

Bug Fixes

Restore attack speed scaling on spears (#2866) by ThomasThePencil

• Fixes a bug where vanilla spears were getting DamageType = MeleeNoSpeed and thus not scaling with attack speed
• Adds ItemID.Sets.Spears

Fix #2020, Terraria no longer minimises on focus loss when in full-screen on Windows. by Chicken-Bones

• Fullscreen is now borderless. Does not minimize when you alt-tab to another window.
• Changing focus will still mute music and ambient sounds, but will not stop other sound effects (like getting hurt). Same as in vanilla Terraria
• Exclusive full-screen does not exist in tML, there's no need for it.

Fixed poor implementation of Load() in ModTileEntity. (#2954) by Mirsario

• Removes the need to call base.Load(mod) when implementing ModTileEntity.Load, consistent with other ModType classes

Porting Notes: #preview-update-log in Discord

Bug Fixes Pushed to Stable in September

Mirsario: Fixed divisions by zero on mod uploads?
Mirsario: Fixed #2924 - tModLoader falsely indicating updates available for mods
Solxanich: Hot Fix draft changes for GoG Download Issue #2887 (#2890)

Removed Hooks/Features

Note: Obsolete hooks have been left in for compatibility where possible, but they will be removed in following months, so please move away from these.
As always, tModPorter is available to help providing hints and refactors.

Chicken-Bones: Mark ModItem.OnCraft as Obsolete

Localization Updates

• Spanish: Thanks to Wolf-Igmc
• Russian: Thanks to Ved_s
• Chinese: Thanks to zzp198

Known Issues

My game doesn't launch, and I'm on Windows!

If you're on Windows 7 or 8.X, or an older Windows OS, installing .NET pre-requisites listed in Microsoft's website might very much help. Especially the KB3063858 update.
If the above doesn't apply or didn't help, try deleting the dotnet folder in the install directory, and try running TML again. There seems to be a bug with extracting needed libraries on some Windows devices, where it may take two attempts. We are actively investigating improvements to remedy this.

Frequently Asked Questions

How do I switch to the 1.4-preview or 1.3-legacy branches of TML?

To switch to anoter branch in steam, just do the following:
1. Right click on tModLoader in Steam and select 'Properties...', then 'BETAS';
2. Select the branch you want in the drop-down menu on top;
3. Close the window. You don't need to enter any passwords.
Please note: 1.4-preview versions of TML are intended to only be used by mod developers and testers who know what they're doing. Some popular mods' authors do not intend for their mods to always work with it.

When 1.4.4 tModLoader???

See the first section of this announcement.

When will tModLoader be 64-bit???

It's already 64-bit!
TML runs in AnyCPU mode with x86_64 natives on .NET 6.0+, using the FNA framework under a singular universal cross-platform release.

I have a 32-bit OS, will it be supported?

Work is finishing up on improving our handling of native libraries, so we can add 32-bit Windows support. If everything goes well in testing, this will be pushed to the stable branch as soon as it is ready, with an announcement in our Discord.
