BSP-Mod Fixes 0.2.0

Minecraft 1.20.1, Forge 47.3.10 or newer, Java 17. Needed on the client and the server. Requires Numina 2.3.13 and Modular Powersuits 2.3.13 exactly. Optional, client only: EMI 1.1.24+1.20.1+forge with JEI 15.74.0.234.

Added

Tinkers' Construct recipes render in EMI. EMI's JEI compatibility layer stopped at an older JEI API and Tinkers calls the newer methods, so every Tinkers category in EMI showed "Error rendering" and entity melting and severing were empty. Five fixes, applied only when EMI 1.1.24+1.20.1+forge is loaded and only on the client; without EMI, or with another EMI version, they are skipped and one log line says why.

• F-11: a null entry in a JEI ingredient list (which JEI's API allows) becomes an empty EMI stack instead of dropping the whole recipe. Tinkers passes null for every entity without a spawn egg, so entity melting and severing show their recipes.
• F-12: EMI's JEI tooltip builder gains getLines() (a live list, so a plugin's edits change what EMI draws), clear(), clearIngredient() and addKeyUsageComponent().
• F-13: a fluid's amount line is offered to the plugin under JEI's key, so Tinkers' "1 Ingot" and nugget lines replace EMI's "1,000 mB" line instead of sitting beside it.
• F-14: EMI's recipe extras builder gains the JEI 15.56 widget methods (drawables, arrows, plus signs, flames, tooltip areas, buttons) with their tooltips, so Tinkers' arrows, icons and hover areas draw and animate.
• F-15: JEI text widgets are drawn (EMI returned them without drawing them), so Tinkers' titles, temperatures and times show.

Changed

Log flooding closed. The refusal and clamp warnings of F-1 and F-2 are throttled to one per player every ten seconds, with a count of the lines held back, so a hostile client cannot fill the server log.

Kinetic Generator in single player. Its position memory is touched by the server thread only. In single player the client's player shares its entity id with the server's, so a jump on the client could cost a tick's credit on the server.

Forge range. The mod now asks for Forge 47.3.10 or newer, the first version that hands the loading context to a mod constructor; older 47.x would have refused to load it anyway.

Startup report. On a dedicated server the EMI fixes are reported as skipped ("client-side only") instead of waiting for classes that never load there.

BSP-Mod Fixes 0.1.0

First release. Minecraft 1.20.1, Forge 47.4, Java 17. Needed on the client and the server. Requires Numina 2.3.13 and Modular Powersuits 2.3.13 exactly: if either is updated the game refuses to start until this mod is updated too.

What it does

Ten fixes for Modular Powersuits and Numina, patched in place with mixins and event handlers; nothing of theirs is shipped or changed. Each fix is aimed at the exact line that was wrong, and each has a headless test. The server log lists the fixes once loading is complete.

Fixed

The suit ticked twice a tick (F-3). Numina's tick handler never looked at the tick phase, and Forge fires the event at the start and the end of every tick, so every module ran twice: double jetpack thrust and drain, double Night Vision cost, double cooling. The suit ticks once now, at the start. Thrust and drain halve with it; the server settings in the description re-tune the jetpack, the jet boots and the kinetic generator.

Powersuits' player update ran on every living event (F-4). It subscribed to the base event, so it ran for every hurt, jump, fall, death and drop of every creature on the server, rewriting the player's fall distance each time. It runs on the player's tick only.

Night Vision charged every tick (F-5). It refreshed the effect whenever under 500 ticks remained but applied a 300-tick effect, so every tick qualified and cost 100 FE (4,000 FE a second with the double tick). It refreshes under 220 ticks with a 400-tick effect: one charge about every 9 seconds, and no flicker.

The Kinetic Generator paid almost at random (F-6). It sampled the walked distance one tick in twenty, only when the player happened to be on the ground at that tick, and its "not generating" branch fell through and paid while flying. It pays its rate per block walked, every tick, on the server, and nothing while airborne, flying, riding, or for a teleport.

The Shock Absorber was all or nothing (F-7). A battery that could not pay for the whole fall absorbed none of it, which is why it failed after jetpacking, and its multiplier ran to ten times the fall. The slider sets the share of the fall absorbed (0 to 100 %), the battery pays its cost per block, and a short battery absorbs the part it can pay for. Falls of three blocks or less are left alone as before. The old landing sound is not played.

The Energy Shield was plain armor that never used energy (F-8). Powersuits added the shield's points to the armor attribute, its energy drain was dead code (the armor cannot be depleted, so Forge never called it), and its tick switched the module off for good whenever energy dipped under one hit's cost. The shield now absorbs part of each hit for energy: 4 % per point as vanilla armor does, 80 % at most, at the module's FE per point absorbed; with less energy it absorbs what it can pay for; damage that bypasses armor is untouched; the armor bar no longer rises; knockback resistance stays; the module stays on.

Raw translation keys everywhere (F-9). Numina ships its English as us_en.json, which Minecraft never loads, so every Numina name showed as its key; Powersuits lacked a keybinding name for every module and a few screen titles. Two small language files in this jar fill the gaps: all of Numina's plus the keys its code uses, and only the keys Powersuits lacks.

Security

Free modules through the creative-install packet (F-1). The Tinker Table's creative-install packet put a fully charged module into a worn item and Powersuits' server handler never checked the game mode, so any modified client could install any module for free in survival. It is refused unless the sender is in creative mode, and the log names the player.

Unchecked slider values (F-2). A module tweak packet carries a raw number that Numina stored unchecked, so a modified client could send 1000 for a thousand times the thrust or a negative energy use. Values are clamped to the slider's own 0..1 before they are stored (NaN and infinity become 0), and the log names the player.

Added

Fire immunity as a setting (F-10). Numina puts out a burning player who wears or holds a modular item while the suit's heat is under 95 % of its maximum. The new bsp_mod_fixes-server.toml has suitClearsFire: true (the default) keeps that, false lets the fire burn as on anyone else.
