I have tried to keep myself out of Freelancer for a time, but I found a way to start story missions in a live server though some weird tricks, I couldnt help myself to finish this thing, in that time I have documented some crash offsets that might be useful

(If anyone wants to see how I did this, I put the source code in the Moddb website in the download link, “Freelancer Co-Op Campaign Mode”, my code is very bad but StartStory() function explains how it is done)

content.dll+1aa9f
_SendMessage (Server uses this to communicate with every function) crashes due to following reason;
if anyone calls Story mission "Act_State = SUCCEED" server will call DestroyInstance for every story instances are running, it will crash the server if there are more than 1 in action 

this can be temporarily fixed by altering the function, which prevents DestroyInstance erase Story instances (it will only stop the last instance which Co-Op mod does for 0x1 iClientID)
(BIG NOTE: this offset effects even random missions, restart the server as soon as "missions" ends)
(Another big note: Act_State = SUCCEED" function itself needs to be changed, in order to have everyone their own instances and make them successfuly finish)

content.dll+49c95
settimer assignment error, unstable instance for unknown reasons

content.dll+89651
reputation based error (happened when SP Story reputation functions are enabled in MP)

content.dll+2d541
story manager tried to submit an order/reputation to a NPC that does not exist
documented this bug at SpawnShip within initState = ACTIVE trigger

content.dll+55796
Client crashed during MP base cutscene when server shut down (crash in DestroyInstance)

content.dll+25cc9
Story trigger, Act_LockDock error?, possible nullpointer base? it might be related to other story triggers too(Previous OPjump does initilaize every trigger of story manager)

Content.dll+2FE8F
AI logic error, as far as I can tell, 3 different functions use this area, one of them controls their orders as they spawn and the other one upon destruction

Common.dll+6c282
Group formation leader error, unknown

Freelancer.exe+13d55a
Client tried to dock to a solar that does not exist from its perspective, either done through SwitchOut or following a formation leader that is docking

Freelancer.exe+1469F6
Client tried to sends its targetting information to the server, but failed (tried to target during SystemSwitchOut)

Freelancer.exe+001aad50
Based on pure speculation, Client tried to switch chars during server froze and it crashed

UNKNOWN/UNKNOWN
Observed multiple times, if a Story mission called a [Trigger] but has no Cnd_ condition line

Server.dll+f988
Client and Server failed to sync jump destination system, causes crash in Singleplayer

Hello everyone I got some crash feedback about some of my offsets, I suggest removing them

1.Auto-CM without activation (crashes with wrecks)
2.Guided projectiles wont give up tracking a target(effects everything in unintentional way)

for the first one, everyone should use BC46’s alternative
and second one here is a better alternative

server.dll+1460C
This will allow 360* FOV missiles and as a side effect, missiles will not give up chasing their targets, if it is 360*FOV

(seeker_fov_deg = 180 means 360* FOV)

0F 8A ED 01 00 00 -> 90 90 90 90 90 90

(as technical note, normally missiles cannot have fov above 180+ due to a limiter that checks missile's trajectory against a target, if it is negative, it kills the seeker)

Just adding this one here too, that is discovered recently

Freelancer.exe+F8C36
Alchemy will read "-1.0" engine state
this will allow -1.0 ALE effects to spawn for reverse impulsing

7A 16 -> EB 16

There was a typo in the new block that I merged, but I had 4 JSON linters all tell me everything is fine. Sometimes it annoys me how the trailing comma is ‘sometimes’ allowed. The auto-deployment failure was caused by a JS peer dependency resolving to the wrong version.

EDIT: the sync seems to be lost again: where did I make a typo?

Think it’s unrelated. Something broken with the auto-deployment. I will investigate.

Laz

Took a quick look, looked good, merged.

I have refactored the V2 page to hopefully be a bit more usable. Please let me know if you encounter bugs or have any feedback about the new design.

Heya everyone. I was wondering if anyone knows what function within Freelancer.exe I can call to cause the the ship to flip between it’s various camera states. I am looking primaraily to convert between the normal view and cockpit view on demand, as well as preventing the user from manually switching back if possible, but I have a few different ways to achieve the latter.

Spent a while looking in IDA trying to follow what happens after the user presses the H key (for turret view) and the like, but can’t seem to find where the game changes the state.

Any help appreciated!

Show all group members on the nav map:
Freelancer.exe, 08DC07, 
E9 85 FD FF FF 90 90 90 -> 83 C5 18 E9 82 FD FF FF

I wasted an entire month trying to figure this out lol (and failed)
nice find, I thought it was drawing only one icon for the group, didnt know thought probability of they are stacked together
