Undocumented Lua functions?

AnthonyBF2 · Post by **AnthonyBF2** » Sat Jan 30, 2016 5:03 pm

As just about any one knows, On can be combined with lots of things to do different things, like OnCharacterSpawn or OnObjectDeath. I was digging around in the game executable and located some things that I did not find in the documentation. I am wondering if any one else has found these and attempted to do anything with them...

ScoreChange -- find when player's current point count change?
DeathsChange -- find when player's current death count changes?
KillsChange -- find when player's current kill count changes?
TargetChange -- when player locks on and changes target?
PlayerChange -- no idea
WeaponChange -- player changes weapons?
FlagReset -- flag goes back to home space
FlagPickUp -- flag gets grabbed
TeamPointsChange
TicketBleedChange
TicketCountChange

I have worked with FlagReset and FlagPickup. They are self-explanatory. I forget what the arguments are at the moment but you can find examples of them in the stock CTF scripts.

I browsed through the executable a long time ago and don't remember seeing KillsChange or DeathsChange... those sound very useful, if they are usable. I can't say I've ever seen them used in any of the scripts that shipped with the mod tools so maybe they aren't fully implemented... and even if they are I guess someone would have to play around with them to determine what their arguments are. Maybe I'll give that a try this afternoon.

If I recall correctly PlayerChange is when you swap classes; however, there may not be too many uses for it considering CharacterSpawn can be used for class swaps as well.

Would you mind writing a quick use of PlayerChange? I may have a wonderful use for this but I suck bad at Lua.

I highly recommend Zerted's Example Finder. That's how I check for usage of Lua functions I'm unfamiliar with.

Says I need Java... -_-"

Congrats on your 500th post!

I'll check right now to see if I can find an example.

Sorry but I am on my phone hotspot that is 25kbs... Not going to be updating anything until I pay my next phone bill to reset data.

Fair enough.
Well unfortunately I was unable to find any examples of how the function is used.

Thanks anyway. I'll fool around with it later on my own.

EDIT: Failed.

I used:

Code: Select all

OnPlayerChange(function(player)
if GetCharacterUnit(player) and 
IsCharacterHuman(player) then
KillObject(GetCharacterUnit(player))
end
end
)

And the debugger cries:

Code: Select all

Message Severity: 3
C:\Battlefront2\main\Battlefront2\Source\LuaHelper.cpp(312)
CallProc failed: (none):0: attempt to call global `OnPlayerChange' (a nil value)
