📋 About This Mod

Adds a (seemingly) simple trajectory arc for thrown explosives!

UsedLunch's Grenade Arc

(made this one on my lunch break because I actually use my lunch)


Description

Fallout 4 lets you see the arc of a grenade before you throw. Trajectory brings that to New Vegas.

The arc is computed in real time from the grenade you're holding, how long you've been cooking it, and the perks you have.

It's unlocked by a new perk, so it's a skill your character earns.


Main Features

  • []New perk Trajectory (level 4, Explosives 30, 1 rank), in the level-up list. [/]

    []A dotted, glowing green arc shows your grenade's trajectory with a flat green ring that marks where the grenade will land. They have no collision (with your grenade).[/]

    []It follows your throw strength: a quick tap draws a short lob, a full cook draws a long throw, and everything in between.[/]

    []It accounts for the perks that change throwing velocity: Heave, Ho!, Loose Cannon, and Project Nevada - Rebalance's Strength-based throwing range (only if you run it; Project Nevada is not required).[/]

    []Optional Mod Configuration Menu page: turn the arc on or off, and choose when it shows - while cooking (default), while cooking or aiming, or whenever a grenade is drawn.[/]

Limitations

  • []The arc is not always exactly perfect - but serves as a precise guideline in OPEN spaces. [/]

    []The arc shows the flight up to the first impact. Bounces and rolls are decided by the physics engine and can't be predicted.[/]

    []Explosives thrown with the grenade animation only - not mines, throwing knives, spears or hatchets.[/]

    []Perks from other mods that change throwing velocity aren't included but may work as a happy accident.[/]


Requirements

  • []xNVSE[/]

    []JIP LN NVSE Plugin[/]

    []JohnnyGuitar NVSE[/]

    []ShowOff xNVSE[/]

    []Optional: The Mod Configuration Menu (for the in-game settings)[/]

The only master is FalloutNV.esm. Built and tested with JIP LN 57. 21, JohnnyGuitar 5. 01 and ShowOff 1. 75.


For console tinkerers, the physics can be adjusted live (see the README): GArcSpeedMult, GArcGravity, GArcPitchOffset, GArcHoldMin and GArcHoldFull.


Installation

  • []Install the requirements ABOVE - they are necessary!!![/]

    []Install with your mod manager, or copy Trajectory.esp and the Meshes and Textures folders into Fallout New Vegas/Data.[/]

    []Enable Trajectory.esp.[/]

    []Reach level 4 with 30 Explosives and take the Trajectory perk.

    (Or from the console: player.addperk XX00080F, where XX is Trajectory's load order index.)[/]

To uninstall, disable the plugin and delete its files. It adds nothing to the world that stays behind.


Shout Outs

  • []Bethesda's Fallout 4, for the idea.[/]

    []jazzisparis, for JIP LN NVSE - the ray casts and reference movement that draw the arc.[/]

    []The JohnnyGuitar NVSE and ShowOff xNVSE authors, for the camera and aiming functions.[/]

    []The xNVSE team, for making any of this possible.[/]

    []lStewieAl, whose Tweaks source showed that holding the throw scales the distance.[/]

    []The Project Nevada team, whose scripts documented the attack control, and whose Rebalance perk the arc respects.[/]

    []The xEdit team, whose record definitions named the "Modify Throwing Velocity" perk entry point.[/]
