Finding and spawning add-on cars

[ikt]

Hi!

 

The popular trainer/menu Menyoo can detect add-on cars and show them in the list with available vehicles to spawn. Since the menu itself doesn't work well with script reloading, I wanted to get this feature stand-alone.

 

Thing is, I can't seem to find any natives related to returning all available vehicles. Do they manage a list of available mod vehicles themselves? Seems doubtful to me.

 

What I did find was all DLC vehicles. Nothing for all add-ons though

 

 

			int num = DLC1::GET_NUM_DLC_VEHICLES();			logger.Write("# of DLC Vehs: " + std::to_string(num));			for (int i = 0; i < num; i++) {				Hash dlcVeh = DLC1::GET_DLC_VEHICLE_MODEL(i);				if (dlcVeh) {					char *name = VEHICLE::GET_DISPLAY_NAME_FROM_VEHICLE_MODEL(dlcVeh);					if (name) {						logger.Write(std::to_string(i) + " " + name + " " + std::to_string(static_cast<int>(dlcVeh)));					}				}			}

Which indeed returns a 197-element large list of all official DLC vehicles in the images. Manual add-on vehicles are missing though.

 

Is there a way for those vehicles?

The solution is to scan the model hash table for all vehicle models.

See SHVDN's GenerateVehicleModelList().

Ah, it wasn't as simple as I hoped it would be. Thanks

thats just because the code isn't very clear, If you find the function in the exe its much nicer

Well, most of it is pretty clear. What modelNum1-4 are/do is unclear to me and why the model list is an array of 32 lists is odd. The code works fine now though, so I'll just need to filter out the normal and DLC vehicles.

 

Would you/crosire mind if this would be released standalone?

 

Edit - Oh, each vector is a group of vehicles. Didn't know R* would store them like that

 

Additional question:

Aside from comparing them to a hard-coded list of already present vehicle hashes, is there a better way?

I didnt know what they were right when i wrote that code. I now know they correspond to fields in a pool that stores all the pointers to model data. This way is the best way, It never requires updating and it will detect all addon vehicles. It also has the advantage that once you have the framework, you can use it to easily grab info for a specific model(not just vehicles) right from memory. You can see this used in SHV.Net for the IsModelAPed property in the model class - a funciton which is unavailable to replicate with natives.
