Summary0003090: Make engineLoadDFF more safe or split into vehicle and non-vehicle loading functions

As the documentation of engineLoadDFF states:

"Optional Arguments

  • model_id: The model id that should be associated with the dff, when loading a vehicle. Always pass 0 (or nothing at all) if you are replacing something else than a vehicle."

Not using the model id for vehicles will result in a crash.

Ideally the function should fail if no model id was passed for a vehicle DFF, but I don't know if there's a quick and reliable way to check whether a DFF that is being loaded is a vehicle model (or in other words: if the DFF contains embedded collisions, which is causing the crash).

TagsNo tags attached.

engineLoadDFF was altered so the 2nd model ID argument is required, but it will still crash when passing a 0 for a vehicle model.

Also the RequestModel you uncommented is unsafe IJs, it should be done through our client DFF classes. Reason for that is that we have a reference system for the model info's, it might work for a few vehicles, but once you try to replace a bigger number of vehicles, GTA will crash because of more than 127 different vehicle models loaded at once. Ie replacing all the cars in SA will crash.

Since r702, the engineReplaceModel works properly with vehicles but only on a server with at least one player and sometimes doesnt works even with those conditions.

Maybe you need to delete all does engine functions and replace it with:

engineLoadVehicle(string txd, string dff, int vehicleID);
engineLoadPickup(string txd, string dff, string col, int pickupID);
engineLoadObject(string txd, string dff, string col, int objectID);
engineLoadPed(string txd, string dff, int pedID);

That should be much easier!

No. The point of the separation into "load" and "replace" functions is that you can reuse loaded files in several models.

Added a patch in CMultiplayerSA to make SA simply ignore any embedded collisions if no model ID is specified.
