Changing idSession would break the interface for Game DLLs, making the existing ports of Mods incompatible. Luckily we have idCommon::GetAdditionalFunction() for cases like this.. Also added a check for WEAPON_NETFIRING in idWeapon::EnterCinematic(), I got an Assert() there in Debug builds. Running the Demo seems to work now, at least I could finish it without any problems (ignoring some warnings in the console)

/* Some Mods (like Ruiner and DarkMod when it still was a mod) used "SourceHook"
|
|
* to override Doom3 Methods to call their own code before the original method
|
|
* was executed.. this is super ugly and probably not super portable either.
|
|
*
|
|
* So let's offer something that's slightly less ugly: A function pointer based
|
|
* interface to provide similar (but known!) hacks.
|
|
* For example, Ruiner used SourceHook to intercept idCmdSystem::BufferCommandText()
|
|
* and recreate some cooked rendering data in case reloadImages or vid_restart was executed.
|
|
* Now, instead of doing ugly hacks with SourceHook, Ruiner can just call
|
|
* common->SetCallback( idCommon::CB_ReloadImages,
|
|
* (idCommon::FunctionPointer)functionToCall,
|
|
* (void*)argForFunctionToCall );
|
|
*
|
|
* (the Mod needs to check if SetCallback() returned true; if it didn't the used version
|
|
* of dhewm3 doesn't support the given CallBackType and the Mod must either error out
|
|
* or handle the case that the callback doesn't work)
|
|
*
|
|
* Of course this means that for every new SourceHook hack a Mod (that's ported to dhewm3)
|
|
* uses, a corresponding entry must be added to enum CallbackType and it must be handled,
|
|
* which implies that the Mod will only properly work with the latest dhewm3 git code
|
|
* or the next release..
|
|
* I guess most mods don't need this hack though, so I think it's feasible.
|
|
*
|
|
* Note that this allows adding new types of callbacks without breaking the API and ABI
|
|
* between dhewm3 and the Game DLLs; the alternative would be something like
|
|
* idCommon::RegisterReloadImagesCallback(), and maybe other similar methods later, which
|
|
* would break the ABI and API each time and all Mods would have to be adjusted, even if
|
|
* they don't even need that functionality (because they never needed SourceHook or similar).
|
|
*
|
|
* Similar to SetCallback() I've also added GetAdditionalFunction() to get a function pointer
|
|
* from dhewm3 that Mods can call (and that's not exported via the normal interface classes).
|
|
* Right now it's only used for a Doom3 Demo specific hack only relevant for base.dll (not for Mods)
