For example, if I wanted to place a trash bin on the side of a trash truck, while it's going uphill, using the default offsets wouldn't work. Would you mind showing me a short example of how to make that work with one of these functions (of course if it's not already added that would be a possible suggestion)? Thanks.

Ok, here's a small example:

pawn Код:

public OnPlayerKeyStateChange(PlayerID, NewKeys, OldKeys) {
    
    // pressing fire key
    if ((NewKeys & KEY_FIRE) && !(OldKeys & KEY_FIRE)) {
        
        if (IsPlayerInAnyVehicle(PlayerID)) {
            
            new vehtype;
            vehtype = GetVehicleModel(GetPlayerVehicleID(PlayerID));
            
            if (vehtype == 564) {// while in RC tiger
                
                new time; 
                time = GetPVarInt(PlayerID, "LastTigerShot");
                
                if (time + 500 < TickCount()) {
                    
                    new Float:turretstart[3];
                    new Float:inp[3];
                    
                    inp[0] = 0.000; inp[1] = -1.2559; inp[2] = 0.3384;
                    MPProjectPointOnVehicle(GetPlayerVehicleID(PlayerID), inp[0], inp[1], inp[2], turretstart[0], turretstart[1], turretstart[2], 1);
                    CreateObject( 921, turretstart[0], turretstart[1], turretstart[2], 0.0, 0.0, 0.0);
                    
                    SetPVarInt(PlayerID, "LastTigerShot", TickCount()); // shot time
                }
            }
        }
    }
}

This is a bit modified code from what i use on partyserver.

When you hit fire key while inside a RC tiger, this will take the turret end point coordinates, and project them thru car's rotations to get exit coordinates in game world space, then create a small light object at those points.

An alternative would be, to extend the exit turret coordinates further, and create a explosion instead, this would make the RC tank able to fire / explode things properly.

Screenshot - notice that objects are placed correctly taking the rc tank's pitch / roll / yaw into account:



You can use this, and get trash van's specific coordinates to place trash cans behind it, it's easy to get coordinates on vehicles - place a car in my map editor at exact 0,0,0 coordinates with no rotation, then click on the vehicle and status bar will show you vehicle-based coordinates.
