Yielding from a coroutine seems to clear a local table

研究方向
Start by reproducing the coroutine behavior with the Lua snippet in the issue, then inspect how the game embeds and resumes Lua coroutines. Compare the local table and other locals across the yield, and trace the resulting behavior to the reported mod error at MeleeHumanBehaviors.lua:1201. Done means explaining or fixing why PathDump becomes empty and confirming the reproduction no longer produces the reported error.

描述
Describe the bug
I expected 5 to be printed a second time here, rather than it becoming 0.
I can't explain the fact that a and #b are still the correct value after the yield, though.
PRINT: 1. #PathDump is:
PRINT: 5
PRINT: 2. #PathDump is:
PRINT: 0
PRINT: a is:
PRINT: 1
PRINT: #b is:
PRINT: 1
since I can't think of a normal way in Lua for coroutine.yield() to alter the local PathDump
-- no waypoint list, create one in several small steps to reduce lag
local PathDump = {}
if Owner.MOMoveTarget and MovableMan:ValidMO(Owner.MOMoveTarget) then
Owner:DrawWaypoints(false)
-- copy the MovePath to a temporary table so we can yield safely while working on the path
for WptPos in Owner.MovePath do
print("Inserting WptPos:")
print(WptPos)
table.insert(PathDump, WptPos)
end
-- clear the path here so the graphical representation does not flicker on and off as much
Owner:ClearMovePath()
Owner:AddToMovePathEnd(Owner.MOMoveTarget.Pos)
else
coroutine.yield() -- wait until next frame
-- copy the MovePath to a temporary table so we can yield safely while working on the path
for WptPos in Owner.MovePath do
table.insert(PathDump, WptPos)
end
end
local a = 1
local b = {"c"}
print("1. #PathDump is:")
print(#PathDump)
coroutine.yield() -- wait until next frame
print("2. #PathDump is:")
print(#PathDump)
print("a is:")
print(a)
print("#b is:")
print(#b)
I am 99% sure the mod didn't have this issue in pre5, as my mod updater script would've noticed this error in the log back then, caused by PathDump being empty:
BoS Initiate GoToWpt error:
Mods/bos.rte/Actors/Soldiers/MeleeHumanBehaviors.lua:1201: attempt to index field 'Pos' (a nil value)
To Reproduce
- Download bos.rte.zip
- Download Benchmark.rte.zip
- Use this in your Settings.ini to instantly have the issue printed when the game boots:
LaunchIntoActivity = 1
DefaultActivityType = GAScripted
DefaultActivityName = Combat Benchmark
DefaultSceneName = Benchmark
