Quick Start

1. Create a prim and drop the aeros / API v[VERSION] script into it.
2. Create a new script inside the prim and copy-paste the following:

OBS_send(key target, string payload) {
  llMessageLinked(LINK_THIS, -78000, payload, target);
}
 
default {
  state_entry() {
  }
 
  touch_start(integer i) {
    // On touch, send ";"-separated command var=val pairs
    // In this example: random stage and vertical angle
    float s = llFrand(1);
    float v = 0.25+llFrand(0.5);
    OBS_send(llGetOwner(), "s="+(string)s+";v="+(string)v);
  }
    
  link_message(integer sender_num, integer num, string str, key id) {
    if (num >= -78002 && num <= -78001) {
      if (llGetOwnerKey(id)!=llGetOwner()) return; // Filter by object owner
      if (num == -78001) {
        // Notifications. Uncomment to monitor:
        // llOwnerSay("[!]\t"+str); 
      } else if (num == -78002) {
        // Intents and constraints sent by the HUD or other attached add-ons.
        // Same-owner only.
        // Use it to learn HUD's commands.
        // llOwnerSay("\t"+str);
      }
    }
  }
}

3. Attach the prim as a HUD.
4. Touch the prim and observe the changes happening with your Device.

You now have a playground ready to experiment with other commands described in API Reference.
