Change character modifiers to a table?

[sparr]

Currently if two mods want to modify the player's running speed modifier dynamically at the same time, there's a problem.

Instead of having a single integer multiplier for speed, what if there was a table? Mods could read and write the table. Keys would be free-form; most mods would put in just one new key. Values would be either +X or *X and would all get applied in some deterministic order (first instinct is + first then *)

You could do this for all modifiers.

I would seriously approve of this.
Starsector makes use of this mechanic, and it is very useful.

Thanks for that amazing implementation example!

Editing the title of the post, and adding another use case:

If two mods both want to double the player's reach, it would be nice if they could both take effect, with their choice of +X or +X%.

+1 this idea. We could also have all those modifiers shown in the effects window (maybe only in debug mode?).

further elaboration on ways to make this idea more flexible:

allow a priority level for a change, similar to data/date-updates/data-final-fixes in mod creation.

allow changes to associate themselves with textual tags, which other changes can reference (or other mods can just search for).

allow a change to specify whether it intends to change the base value or is operating as a temporary or permanent bonus to the base.

allow a change to specify whether it should not apply if the result exceeds some cap or floor.

Stickers can be used to accomplish this for character and vehicle speed, with many mods each being able to stack and manage their own modifiers independently.
