With the recent advent of ADXP|MCO, SCAR, and poise mods, a stamina system is necessary for gameplay balance. ADXP|MCO + SCAR allow enemies to chain infinite combos while poise mods potentially trigger constant staggers. None of the mods I've tried that offered a stamina system really worked in the way I wanted.
I'm currently working on a Dodge Attack Stamina (DAS) framework mod that's written entirely as an SKSE plugin for SE/AE. It consists of a dodge framework, dodge stamina system, and attack stamina system. Since I'm not versed enough in the myriad of mods out there that offer similar features, I'm asking the folks here for some feedback on the features.
Dodge Framework
Sprintkey dodge + hotkey dodge are implemented and currently supports dodge animations from DMCO (8-way dodge) and TK Dodge (4-way dodge).
I like DMCO's double tap feature and implemented it for TK dodge animations (single tap for step dodge, double tap for dodge roll).
The ultimate goal is to create my own Nemesis patch for animations, but that's a low priority.
Dodge Stamina
Stamina cost for dodge is based on the player's body weight and player's equipment weight. This allows light/cloth armor to use less stamina for dodging as a way to balance poise mods that favor heavy armor.
DMCO is an amazing dodge mod, but I just do not like its implementation of the stamina cost (as of v0.96). TK Dodge simply has a fixed stamina cost.
Attack Stamina
Stamina cost is based on weapon weight for melee/bow/crossbow attacks and magicka cost for magic attacks. Affects player and NPCs.
For melee attacks, the stamina cost is applied per weapon swing event. For example, a dual wield attack animation consists of 3 weapon swings (right, left, right) on a single button press. The stamina cost is applied for each weapon swing using the weight of the weapon that was used in each swing.
For bow/crossbow, stamina cost is applied during bow draw and again during arrow release. Crossbow works in reverse (bolt release, bolt reload).
For magic attacks, the cost is applied after a spell cast. Currently, concentration spells have a single cost. I haven't figured out how to hook into the spell cast function to apply cost per second.
The multipliers for dodge stamina and attack stamina can be individually configured by the player. All the features listed are fully implemented and functional.
