Hi there,

I have instant CTD every time I use a bandage then a medkit.

Here is the stack trace:

FATAL ERROR

[error]Expression    : fatal error
[error]Function      : CScriptEngine::lua_error
[error]File          : E:\stalker\sources\trunk\xr_3da\xrGame\script_engine.cpp
[error]Line          : 73
[error]Description   : <no expression>
[error]Arguments     : LUA error: ...es\stalkersoup\gamedata\scripts\dmx_medicines.script:167: attempt to perform arithmetic on upvalue 'act_health' (a nil value)

stack trace:

Can anyone help me on this?
thx

RESPONSE from nekomaster:

I found the culprit, when you deactivate the "dmx_hide_weapon" option in modder's script, this makes the function "medical_hide_wpn" in dmx_medicines.script crash because lines 151 and 243 are commented.

The function need to be like that to prevent crashes:

Code:: function medical_hide_wpn(obj_section)
if dmx_hide_weapon == true then --110019 // HERE, REMOVE THE "--" AT THE START OF THIS LINE
if not (has_alife_info("advanced_outfit_used") or has_alife_info("bar_arena_fight")) then
--utils.info_msg("2", script_name(), "medical_hide_wpn:", "act_health value: "..utils.ToString(act_health))
if food_tabl[obj_section] then
dmx_medical_hide_wpn(5)
elseif drink_tabl[obj_section] then
dmx_medical_hide_wpn(4)
elseif medical_tabl[obj_section] then --110017.1
if obj_section == "medkit" then
if not has_alife_info("actor_medkit_use_info") then

EDIT from nekomaster: So using those changes I'm STILL having this crash/error when I use bandages and then a medkit right after

Code:: FATAL ERROR

[error]Expression : fatal error
[error]Function : CScriptEngine::lua_error
[error]File : E:\stalker\sources\trunk\xr_3da\xrGame\script_engine.cpp
[error]Line : 73
[error]Description : <no expression>
[error]Arguments : LUA error: ... - stalkersoup\gamedata\scripts\dmx_medicines.script:167: attempt to perform arithmetic on upvalue 'act_health' (a nil value)

stack trace:

I copied and pasted the code-snippet from the first post and replaced the exact same section in my dmx_medicines.script just so I dont miss anything and yeah it still crashes for me with the same error that the first post was complaining about and suppossedly fixed.

EDIT from nekomaster: For now I commented out these lines...

Code:: db.actor.health = act_health - 0.xx

(where xx = the value)

...aaaaand the game functions fine without them!

Just means that now the warnings in the news will always appear regardless of the player/actors health but I think this is a fair trade off to have stuff work.

Either way in the end using medkits or morphine works and hides weapons without issue or crashes

(I think I managed to solve my issue with my own code tweaks lol)

My apologies, but in editing the above post for conciseness, I inadvertently sent it back in time to last February... Rolling Eyes

This combined post from Semtex, with a very useful fix from nekomaster, should be dated today

Enh, either way, so long as people can find the fix, which ever works, is what counts in the end.

I'm just glad my hack works (at least for myself)

I have the same issue, however I don't have the dmx_medicines.script file and I'm not sure how to get a hold of it. I tried to extract it from the game files but all I got was a garbled mess of missing characters.
