Show / hide objects by HUD Script

[MIVIMEX]

Hello! Please help to make a script for three button HUD to make one of the objects in the linkset visible. 

Thanks for any help!

Im noob to scripting and already posted at wanted too, please pardon for double post!

Very needed!

By now, you know that we are not likely to provide full scripts here in the LSL Scripting forum, except as rough examples, so you are most likely to get a good response from your post in the Wanted or InWorld Employment forums.  If you are planning to write your own script, though, all you need to do is have each HUD button trigger a unique message to whatever you are trying to control.  Then, provide the object that you want to control with a script that says, "When you hear the message '1', become visible.  When you hear the message '0', disappear." Send the message with llRegionSayTo, aimed at the specific object that you want to control, or include something in the message that can only be understood by that object.

Do I understand correctly that two scripts are needed: for the object and for the HUD?
I'm afraid of HUDs like fire! I know it too much but can you give a simple example? Please!

A HUD is not a special object.  It is like any other object that you script.  In fact, it's usually easiest to write and test a HUD by building your script in  prim on the ground.  Just make your script say something when you click on it.  Then write a script in some other object to listen for that message and do something when it hears the message. It's no more difficult than that.

Hello! I was given two such scripts for HUD and for objects. But they do not work exactly the way I want. Could you help me fix them? The click on a button makes the object visible and the second button invisible. But I need that when you click on a certain button, the selected object in the link set becomes visible and the other two are invisible. If you are interested please let me know. Thank you so much.

 

HUD

LINK SET

    listen(integer channel, string name, key id, string message)
    { if( message == "invis")

      }
      if( message == "vis")
      {  llSetLinkAlpha(LINK_THIS, 1.0, ALL_SIDES);
      }
    }
}

you want to use a single script in hud?

if you use a multi script sistem you can solve easily this problem

bt 1 texture transmitter (uuid of texture)

bt  2 texture transimitter (uuid Alpha texture)

You should try sending messages like "vis1", "vis2", "vis3" from the HUD and then check which of those messages was received in the target object.

Rough example so you can have some practice:
If "vis1", llSetLinkAlpha(link1, visible), llSetLinkAlpha(link2, invisible), llSetLinkAlpha(link3, invisible)

Wow! Thank you so much! Two heads is better than one! So thats what I got but it says: name not defined (link1,2,3) How do i define this names?

default
{
    state_entry()
    { llListen(-25, "", "", "");
    }   
    listen(integer channel, string name, key id, string message)
    { if( message == "vis1")
      {  llSetLinkAlpha(link1, 1.0, ALL_SIDES);
         llSetLinkAlpha(link2, 0.0, ALL_SIDES);
         llSetLinkAlpha(link3, 0.0, ALL_SIDES);
      }
      
      if( message == "vis2")
      {  llSetLinkAlpha(link1, 0.0, ALL_SIDES);
         llSetLinkAlpha(link2, 1.0, ALL_SIDES);
         llSetLinkAlpha(link3, 0.0, ALL_SIDES);
      }
      
      if( message == "vis3")
      {  llSetLinkAlpha(link1, 0.0, ALL_SIDES);
         llSetLinkAlpha(link2, 0.0, ALL_SIDES);
         llSetLinkAlpha(link3, 1.0, ALL_SIDES);
      }
    }
}

 

Please help!

Hello! Thanks for responce! Yes it can be a multiscript, but what is texture transmitter? Tell me please?

[pixstudio]

you must create real button in the hud , in every button put the script, that telling the message to the listener

transmitter

integer ch =-25;

key msg= "the txt of your message";

llSay (ch, msg);

Thank you all very much! The problem was solved!
