📋 About This Mod

Since Yvileapsis (the author of Just Assorted Mods) seems to be taking a break from New Vegas right now, and the permissions for JAM are open, I'm posting this addon which improves various factors of Bullet Time.

This addon requires JAM, and will only work with the merged version - not the standalone JBT.

A version for standalone JBT will not be made.

There will be no attempt made to try to fix the vanilla killcam function when turned on with bullet time, as it is oblique and engine related.

Features:

[]Highlighting has been made active, rather than dynamic - it will now highlight the limb you are currently aiming at, instead of the limb you last hit.

While this feature may be a little jank, it's more responsive and active than the alternative, and not worse than vanilla VATS targeting by any means. See video for demonstration.[]Fixed a bug where JBT's highlighting would occasionally label body parts wrong.

For example, a Cazador's right wing would occasionally be displayed as "right arm".[]A system allowing for proactive perk modifiers has been implemented. Previously the perks Sniper, Center of Mass, and Hobbler would only modify your accuracy and damage for the next shot after you land a hit on a limb that qualified for that perk. Perks can now pre-emptively modify various factors during Bullet Time, such as spread, damage, reload speed, attack speed, and movement speed, based on the targeted limb, weapon used, target type, and more.

[]JBT's initial compatibility with VATS related perks used the standard values for the base game perks, and it was not dynamic to potential changes to those perks without an explicit patch to JBT's internal perk. This has been reworked with scriptlets which can be dynamically removed and replaced by other mods which intend to alter the VATS related values associated with those perks.

[]Other mods can now create their own scriptlets to inject into formlists present in this mod which allow them to affect the calculated factors specified above, without needing to make this mod a requirement for their own file. Information for mod authors on how to implement this can be found below.

[]A modifier for JBT's time multiplier based on Perception has been added, which can be adjusted through the MCM. The configurable value coordinates to how much each additional point of Perception will multiply the current time multiplier. Set this value to 1. 0 to remove Perception's effect on the time multiplier.

[*]Added proper support for the perks Mysterious Stranger and Miss Fortune. These characters will now actually have a chance to appear and lend you a hand during Bullet Time. These appearances will properly increment the relevant Pip-Boy stats and challenges, and perks like the challenge Friendly Help will alter their chance of appearing, just like they do for VATS.
