Need help with some classes and vehicles.

If you're making a custom vehicle you might need to include some scripts within the .cfg file.

In @$sprite_scripts :

Code:

SeatsGUI.as;
VehicleGUI.as;
VehicleConvert.as; # If you want enemies to be able to capture the vehicle

In @$scripts :

Code:

Seats.as; # This has to be above Vehicle.as, etc
Vehicle.as;
VehicleConvert.as; # If you want enemies to be able to capture the vehicle

You can look for some other interesting scripts to add from Catapult.cfg, for example RunOverPeople.as, PopWheelsOff.as.

You can change the shape of the vehicle in the configuration file as well, changing the vertices :

Code:

@f32 verticesXY                            =  8.0; 6.0; 
                                               24.0; 6.0;                                               
                                               32.0; 24.0;
                                               24.0; 27.0;
                                               8.0; 27.0;
                                               0.0; 24.0;    

However, some vehicles such as warboats have in fact more shapes that are instantiated onInit in their script.
This is how it's done in WarBoat.as :

Code:

    {
        Vec2f[] shape = { Vec2f(43.0f,  4.0f) - pos_off,
                         Vec2f(73.0f,  7.0f) - pos_off,
                         Vec2f(93.0f,  36.0f) - pos_off,
                         Vec2f(69.0f,  24.0f) - pos_off
                       };
        this.getShape().AddShape(shape);
    }

To create a new vehicle it's necessary to do extra stuff code side. Dinghies might be the easiest one to learn from.

Seats and other attachments are listed in @$attachment_points (this is Catapult.cfg) :

Code:

# name; pixel offset (from center) X; offset Y; socket/plug 0/1; controller; radius
DRIVER; 0; -3; 0; 1; 12;
GUNNER; -16; -1; 0; 1; 12;
MAG; -9; -19; 0; 0; 24;
VEHICLE; 0; 8; 1; 0; 0;

Some of these attachments might be handled directly by the common vehicle scripts, or by the catapult scripts in this case.
You can add custom attachments to attach blobs as you'd like. WarBoat.as does this :

Code:

    if (getNet().isServer())// && hasTech( this, "mounted bow"))
    {
        CBlob@ bow = server_CreateBlob("mounted_bow");
        if (bow !is null)
        {
            bow.server_setTeamNum(this.getTeamNum());
            this.server_AttachTo(bow, "BOW");
            this.set_u16("bowid", bow.getNetworkID());
        }
    }

 

DRIVER is the seat to drive the vehicle (move it around)
GUNNER is the seat for the firer (shooting ballista bolts for the ballista, or people, stone, etc in the catapult)
MAG looks like the attachment for the ammo (to attach blobs put in correctly, e.g. players, bombs)
VEHICLE is likely a special attachment, I don't think you will need to change it.

 

VEHICLE Attachment Point is used when embarking cata/ballista on warboat/longboat/bomber. boats have socket/plug field for this AP set to 0 (socket), while land vehicles are set to 1 (plug). so effectively boats "pick up" other vehicles on contact
