# Description
They say Rome wasn't built in a day, well this entire PR was coded in a
single 6 hour Adderall binge. This PR represents the next big leap in
code capability for the PsionicSystem, completely reworking how Psionic
Powers are added and removed, such that like the TraitSystem, they
utilize modular functions governing how they work. Instead of there
being only 5 different hardcoded things that Psi Powers can do, there is
now a library containing 21 different modular functions, which are
slotted as desired into the power prototypes.
Additionally, a significant improvement in the logical flow of this is
that since each power is responsible for its own "removal codepath",
it's now possible to remove individual powers from a character, as
opposed to always needing to wipe the slate clean entirely.
I'm not going to add any new powers in this PR, nor am I touching the
code for the Psionic Actions themselves, that'll come in Part 2, in
which I refactor the Psionic-Actions so that they also operate on
similar stacks of modular functions.
This PR also makes extensive refactors to the PsionicPowerPrototype, as
well as PsionicAbilitiesSystem, so that it has all new hooks and
datafields for other systems to be able to modify a psion. It is now
entirely feasible to create unique "Types" of Psions, with their own
distinct power lists. It's also now possible to create "Tech Trees" of
powers, by setting up powers such that they write to and modify the
personalized pool of available powers to generate. For example,
Xenoglossy and Psychognomy are now dependent on Telepathy, and simply
won't appear in the list of available powers if a Psion doesn't first
have Telepathy.
# Changelog
🆑
- add: Psionic Refactor V3 is here! No new powers are added in this
update, but the options for creating new powers has been SIGNIFICANTLY
EXPANDED.
- add: Xenoglossy and Psychognomy now can only be rolled if you first
have the Telepathy power.
- add: Breath of Life can now only be rolled if you first have the
Healing Word power
- add: Pyrokinesis and Summon Imp now require the Pyroknetic Flare power
- add: All new Psychognomy descriptors for many pre-existing powers.
Have fun being unintentionally screamed at telepathically by someone
with the POWER OVERWHELMING trait.
