Hud melee script not working correctly.

[TheGovnor]

Hi I feel like a dosh.  Im new to scripting...

I have made a hud and scripted it to act like an on off button.  It works fine.

I have a melee script that i took from a weapon and then added the hud script to it, it saved without issue.

I have then put the melee+hud script into the object (hud) and added the animations etc.

The problem is when I touch the hud and it turns on, the melee part of the script wont activate.  The on state triggers the Draw msg..but for some reason the rest of the script isnt hearing the msg.

If I wear the weapon with the origonal melee script in it and then press the hud on screen the melee weapon activates o.O.  If I take off the weapon and wear just the hud with melee/hud script joined..the hud will trigger the melee part of the script if I type /65 draw in chat and all works fine o.O.

So communication is happening...just not within the joined melee/hud script itself.

I have looked and looked and tried alsorts of things but the press on wont activate the melee script when the two are as one script -_-.

I dont know what Im doing wrong, but feel its something to do with the melee script coming from an wear on avatar and the hud script isattachment to screen.  So they are not communicating as one, but will when seperate.  its doing my head in cos it probably very simple to fix grrr.

Hope this isnt to confusing..please help.

without seeing some part of the scripts where you think the issue might be then it's pretty hard to give you a exact pointer

but generally tho the HUD does need to send a message on a channel that the melee weapons can hear. llRegionSayTo is a good place to start looking at this

Ok here are parts of the script.

 

string ownerName;

integer switch;
integer COM_CHANNEL = -12345;
integer status;

string draw_command = "draw";
string sheath_command = "sheath";

ButtonPress()
{
llSetLinkPrimitiveParamsFast(LINK_THIS, [PRIM_SIZE, <0.01, 0.0775, 0.0775>]);

llTriggerSound("e6b5e02f-5d8a-831b-a951-0481981740b4",1);

llSleep(0.025);


llSetLinkPrimitiveParamsFast(LINK_THIS, [PRIM_SIZE, <0.01, 0.1000, 0.1000>]);

}

default
{
on_rez(integer params)
{
llStopSound();
llSetLinkAlpha(LINK_SET, 1.0, ALL_SIDES);
llSetLinkAlpha(1,0.0,ALL_SIDES);
ownerName = llKey2Name(llGetOwner());

}
state_entry()
{

llListen(COM_CHANNEL,"", NULL_KEY,"");

integer perm = llGetPermissions();
if (perm != (PERMISSION_TAKE_CONTROLS | PERMISSION_TRIGGER_ANIMATION))

}

touch_start(integer total_number)
{
ButtonPress();

if (switch==0)
{
switch=1;
llSay(COM_CHANNEL,"draw");
}
else if (switch==1)
{
switch=0;
llSay(COM_CHANNEL,"sheath");
}
}

attach(key on)
{
if (on != NULL_KEY)
{

integer perm = llGetPermissions();

}

}

listen( integer channel, string name, key id, string message )
{
if(llGetOwner() != llGetOwnerKey(id)) return;

if(message == draw_command)
{
weapon_show();

}
if(message == sheath_command)
{
weapon_hide();

}
}

I'm not sure I understand what you're doing, but just in case it's this simple: As the wiki says, "A prim cannot hear/listen to chat it generates. It can, however, hear a linked prim."

[TheGovnor]

 What I was trying to do is put the on off  script inside the melee script and activate the melee script via the on off one within the melee script.    Hud will have to be 2 linked prims for it too work then, makes sense now....how did I miss that part .

[wherorangi]

seems what you have is 3 attachments. A HUD (button), a sheathed weapon and a weapon in hand. The sheathed and hand weapon show/hide (with appropriate animation) when the commands "draw" and "sheath" are typed on channel 65

and what you want to do is click the HUD button to issue the commands, and not have to type the commands in chat ?!

if so then in the weapon(s) script(s) change the channel they listen on from 65 to the same as COM_CHANNEL in the HUD script

a normalised HUD (button) script (which you kinda basically have done already) is something like:

 

integer COM_CHANNEL = -12345;integer switch;default {   touch_start(integer total_number)   {      string cmd;      if (switch)      {          cmd = "draw";      }      else      { 	 cmd = "sheath";      };             llSay(COM_CHANNEL, cmd);  // tell the weapons script(s) what to do      llOwnerSay(cmd);          // tell the owner the last command            switch = !switch;         // flip the switch   }}

 

and other than changing the channel no. in the weapons script(s) you shouldn't have to do anything else to them, for them to work out-the-box

[Qie Niangao]

Or you could do more extensive surgery to the scripts so that, instead of chat/listen, the internal communications are by linked message, which not only works within an object but also within a script (although, if these scripts are actually combined, there may be more efficient ways to integrate their logic, but at the price of understanding more of their internals).

All is working how I would like it too now. 

 

Ty for your help and suggetions .
