/*! How move speed for mobs works
|
|
|
|
|
|
|
|
|
|
Move speed is now calculated by using a list of movespeed modifiers, which is a list itself (to avoid datum overhead)
|
|
|
|
|
|
|
|
|
|
This gives us the ability to have multiple sources of movespeed, reliabily keep them applied and remove them when they should be
|
|
|
|
|
|
|
|
|
|
THey can have unique sources and a bunch of extra fancy flags that control behaviour
|
|
|
|
|
|
|
|
|
|
Previously trying to update move speed was a shot in the dark that usually meant mobs got stuck going faster or slower
|
|
|
|
|
|
|
|
|
|
This list takes the following format
|
|
|
|
|
|
|
|
|
|
```Current movespeed modification list format:
|
|
|
|
|
list(
|
|
|
|
|
id = list(
|
|
|
|
|
priority,
|
|
|
|
|
flags,
|
|
|
|
|
legacy slowdown/speedup amount,
|
|
|
|
|
movetype_flags
|
|
|
|
|
)
|
|
|
|
|
)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
WHen update movespeed is called, the list of items is iterated, according to flags priority and a bunch of conditions
|
|
|
|
|
this spits out a final calculated value which is used as a modifer to last_move + modifier for calculating when a mob
|
|
|
|
|
can next move
