Hey fellow coders,

Ive been trying to save the vehicle quaternion (advanced rotation position) with code similar to this:

CODE

f32 X,Y,Z,W; Ped ped; Player playerIndex = ConvertIntToPlayerIndex(GetPlayerId()); GetPlayerChar(playerIndex, &ped); if (IsCharInAnyCar(ped)) { PrintStringWithLiteralStringNow2("STRING", "Trying", 1000, 1); GetCarCharIsUsing(ped, &veh); GetVehicleQuaternion(veh, &X, &Y, &Z, &W); SetVehicleQuaternion(veh, X,Y,Z,W); PrintStringWithLiteralStringNow2("STRING", "Success!", 1000, 1); }

but my game crashes just by using any of the quaternion functions. any ideas why, have you used it before? anything im doing wrong?

It's for a almost-finished project i have, a time-control mod where u can go back in time.

I done something with this ages ago for GTAIV/SA:

CODE

SetVehicleQuaternion(0.0,0.0,0.0,1.0);

CODE

SetVehicleQuaternion(float x,float y,float z,float s) { *(FLOAT*)(c_player_struct + CPlayerInCarSyncOffset + offsetof(InCarSync,QuaternionX)) = x; *(FLOAT*)(c_player_struct + CPlayerInCarSyncOffset + offsetof(InCarSync,QuaternionY)) = y; *(FLOAT*)(c_player_struct + CPlayerInCarSyncOffset + offsetof(InCarSync,QuaternionZ)) = z; *(FLOAT*)(c_player_struct + CPlayerInCarSyncOffset + offsetof(InCarSync,QuaternionScal)) = s;

CODE

SetVehicleQuaternion(0.0,0.0,Grad2Roll(t_z),0.0);

CODE

SetVehicleQuaternion(CurrentBlockInCarData.QuaternionX,CurrentBlockInCarData.QuaternionY,CurrentBlockInCarData.QuaternionZ,CurrentBlockInCarData.QuaternionScal);

CODE

SetVehicleQuaternion(t_car, data->angle[0], data->angle[1], data->angle[2]);

This is all I have laying around on my PC, don't know if anything will work some code is from SA & other is from GTAIV, but I am not sure, you can figure that out which one is which game haha But good luck hope this helps

Also pm me I have a request for you

hmm, you have some strange SetVehicleQuaternion functions there, u sure all of them ain't just SA?
cause in iv the first var is vehicle, then 4 rot vars.

lol, figured it out, seems i just messed up func def. solved.
