Custom Commands

If you have added a custom script to your vehicle, you can send custom commands to it using the Driver HUD and Gesture Control.

Any command sent through the system via the Driver HUD and Gesture Control that is not assigned to an ACS function in the above list, is sent to the linkset on channel 500. This allows you to add functions for your own custom scripts to the Driver HUD.

For example, if you have a custom script that makes your vehicle explode, have it monitor for the link message Explode, and add the Explode command to the Driver HUD or Gesture Control.

Your link message section of your custom script may look something like this:

link_message(integer sender_num, integer num, string message, key id)

        if (message=="Explode")
            //Do stuff here

Adding physical controls to vehicle dash

You can issue these commands directly from dash-mounted controls (or any prim linked to the vehicle). Send a link message to the root prim with the command as a message.

Here is an example for a dash mounted windshield wipers switch:

    touch_start(integer total_number)

Channel 100 is a good unused channel. (Also see: API/Link Messages)
