What tModLoader/tModLoader shipped

New this week: declarative armor set bonuses mods can query, GlobalTile PostTileFrame and ModifyFrameMerge hooks, and tModPorter support for three 1.4.5 changes. Plus fixes for Paladin's Shield, double-scaled projectile knockback, Nano Flask, stale map entries and modded boss bag

This week's updates for tModLoader include declarative armor set bonuses, replacing hard-coded logic so mods can query armor sets directly, and new PostTileFrame and ModifyFrameMerge hooks on GlobalTile. tModPorter now covers three more 1.4.5 changes: the UIElement.OnDraw SpriteBatch parameter, Player.selectedItem and Player.nonTorch. Bug fixes address Paladin's Shield damage reduction and null-reference errors, projectile knockback being scaled twice, the Nano Flask bonus for melee projectiles and whips, stale map entries after removing modded tiles and walls, and boss bag map icon caching after item array resizing. Steamworks.NET moved to 1.6.5, adding Linux ARM64 support, and several porting TODOs were removed after investigation.

This week: NPC shop materials now marked as materials, arrow ammo and Nano Bullet damage bonuses restored, ammo selection hooks restored for 1.4.5 cycling, server-only decompile no longer needs Terraria.exe, and Ram Rune jump logic updated. Two builds released with the ru-RU upda

This week's changes to tModLoader focus on fixing behavior that affected modded items and combat. Material items in NPC shops are now marked as materials, so they get the tooltip, work in the Guide's crafting interface, and stack correctly. Arrow ammo damage bonuses are restored in PickAmmo, and Nano Bullet's bonus now applies to ammo and weapon damage. Ammo selection hooks are restored for 1.4.5 cycling, so CanChooseAmmo and CanBeChosenAsAmmo are respected and guns can no longer consume ammo their mod rejects. Server-only decompilation no longer requires an installed Terraria.exe on a clean machine, Ram Rune jump logic was updated with a CancelAllJumpVisualEffects check, and the ru-RU localization was updated across two released builds.

V2026.10.1.6 ships modded grass support and ExampleGrass. Also this week: wire visibility hooks, a ModSky class, ModLiquid save/load, prefix roll fixes and a full-server listener backport.

This week tModLoader shipped v2026.10.1.6 with modded grass support and ExampleGrass examples. Modders also gained hooks to control wire visibility and placement, a ModSky class for sky boilerplate, and ModLiquid backend support for save, load and networking. Fixes landed for crafted and dropped items never rolling prefixes, DisplayHoverText on the Horizontal Bars resource display, and smart wall placement ignoring the modded open door hinge barrier. Terraria 1.4.5 full-server listener behavior was backported to keep the server accepting connections correctly.

This week: v2026.10.1.2 released, modded pylon map icons fixed, ConsumeIngredient hooks restored, NPC shops updated for 1.4.5.8, and summon prefix, explosive, shimmer and dismount docs updated.

This week the project released v2026.10.1.2 and shipped a set of fixes and documentation updates for modders. Modded pylon map icons now clamp to the screen edge and pan like vanilla on the fullscreen map, and the ConsumeIngredient hooks fire again during crafting. NPC shops were updated for 1.4.5.8, with changes to the Skeleton Merchant, Clothier, Stylist and Witch Doctor. Summon prefix behavior was updated so prefixes are no longer inherited from the magic damage class, the explosive projectile guide and ExampleMod comments now match the 1.4.5 bomb damage flow, and shimmer and dismount documentation was clarified. The setup command line tool now shows download progress.

This week: trust prompts for downloaded mods, support for 1.4.5 projectile pickup, library mod filtering, and multiple 1.4.5 compatibility updates.

TModLoader releases this week focus on security and 1.4.5 compatibility. New trust prompts warn users before enabling downloaded mods, addressing reports of malicious.tmod files. Support added for Terraria 1.4.5.7's projectile pickup feature. Library mods now filter separately in the Mods menu. Multiple porting notes cleaned up as vanilla implementations supersede previous workarounds.

New improvements to modded accessory loadouts, IME input support for multi-language modders, and fixes for packet processing deadlocks. tModLoader continues bringing mod API support in line with Terraria 1.4.5.8.

This week's tModLoader updates focus on quality-of-life improvements for mod creators. Modded accessory loadout sharing and slot highlighting now work correctly, matching vanilla behavior. International modders benefit from proper CJK input method support, while a critical networking issue preventing packet processing deadlocks has been resolved. New API conditions and projectile AI style IDs keep tModLoader aligned with Terraria 1.4.5.8.

TModLoader updates: Fixed MapHelper tile lookup validation, restored ProjectileLoader.PreKill invocation, corrected Projectile immunity initialization, and synced to Terraria 1.4.5.8.

This week's tModLoader updates address several important stability issues for the 1.4.5 branch. We fixed an invariant check in MapHelper.TileToLookup that was causing continuous failures, restored ProjectileLoader.PreKill invocation code that was accidentally removed, and corrected the initialization of Projectile.perIDStaticNPCImmunity. We also improved Item.SetDefaults() migration handling and enhanced documentation for newly exposed API parameters.
