Scripting A Key To Open Doors/Chests...

[AerolKnight Moonites]

Don't know if this is the right place for this or not.... But I've been trying to find the scripts but no luck so far.... I did find a freebie on marketplace but it's no perms so can't see how it's done... I wan't to be able to script a treasure chest or any door that requires you to wear the key to open the door. I'm wondering how complicated it might be or if anyone has a script/s I could use/have for it already...

[Randall Ahren]

I would think it would be easy. Script you lock box to listen on a special channel for "open", such as channel -994. Script a key to whisper "open" on that channel so that an avatar that has the key in the close vicinity of the lock box can open it up.

[AerolKnight Moonites]

Thanks, but I'm rather new to scripting still and not even sure how to start, or which type of scripting would be needed...I may need more scripting practice before I can figure it out on my own...I'm wondering if there's a basic script I can work from already.

[Jenni Darkwatch]

Simply put, the key needs to listen on a specific channel. The door needs to send a request to the key, and the key needs to respond with a passphrase the door recognizes. Now that there's llRegionSayTo() it's actually fairly trivial.

Step by step:
1. Avi touches door/chest
2. Door/chest sends llRegionSayTo(llDetectedKey(0),...)
3. Worn key gets the message and replies directly to the prim with llRegionSayTo(kDoor,...)

If you need it more secure, you'll need a password/passkey scheme.

[Rolig Loon]

There are many ways to do that. Possibly the easiest is to make the door and the key communicate on the same hidden channel.  If the door only unlocks on a command on that channel, you have to have the key to do it. 

If you actually want to require the key holder to wear the key, you can do something like this....

attach( key id){    if (id != NULL_KEY)    {        llSensorRepeat("Treasure_chest","",ACTIVE|PASSIVE,10.0,PI,5.0);    }}sensor (integer num){    llRegionSayTo(llDetectedKey(0),CHAN,"Open Sesame!"); //Where CHAN is your secret channel}

 ETA:  Obviously, have the door listen for "Open Sesame" on channel CHAN.  I'd put a timer in the door to lock it again in, say, 5.5 seconds.  The key will continue to send an unlock signal every 5.0 seconds while it is being worn within range but the door will lock again once the keyholder either detaches the key or walks out of sensor range.

because it's a neat application and simple, you're in luck... here's how I'd do it...

/*( Simple Lock )*/string gStrLockName = "Uber-Secret Name";default{    state_entry(){        llListen( -1, "Key", "", gStrLockName );    }        touch_end( integer vIntTch ){        llWhisper( 0, llDetectedName( 0 ) + " tries to open the lock..." );        string vStrTemp = llGetObjectName();        llSetObjectName( "Lock" );        llRegionSayTo( llDetectedKey( 0 ), -1, "Keys Please" );        llSetObjectName( "key" );        llSetTimerEvent( 2.0 );    }        listen( integer vIntChn, string vStrNom, key vKeySrc, string vStrMsg ){        llSetTimerEvent( 0.0 );        llWhisper( 0, llKey2Name( llGetOwnerKey( vKeySrc ) ) + " has the right key!" );        //-- do whatever you need to do to open/unlock the item here    }        timer(){        llWhisper( 0, "... but doesn't seem to have the right key (must be worn)" );        llSetTimerEvent( 0.0 );    }}

 and

/*( Simple Key )*/string gStrLockName = "Uber-Secret Name";default{    state_entry(){        llListen( -1, "Lock", "", "Keys Please" );    }        listen( integer vIntChn, string vStrNom, key vKeySrc, string vStrMsg ){        string vStrTmp = llGetObjectName();        llSetObjectName( "Key" );        llRegionSayTo( vKeySrc, -1, gStrLockName );        llSetObjectName( vStrTmp );    }}

 I encluded name swapping so that the keys and locks can be named anything and still use good filters... llRegionSayTo will only be heard by the targeted prim, or the attachments of a targeted avatar (when not using channel zero, otherwise the avatar only hears it)

ETA:
currently will break if the avatar is sitting on something, but that little bug should be gone after tuesdays restart (already gone on at least on of the release channels.

ETA2:
fixed typos

Cool, thank you fro all your help, btw the simple door one said syntax errors... I hate when that happens, and does it matter about prim rotatiion/sizes? (Love yall btw ty very much.^^)

[Darkie Minotaur]

Void must have been tired - just some typos - it should work now

/*( Simple Lock )*/string gStrLockName = "Uber-Secret Name";default{    state_entry(){        llListen( -1, "Key", "", gStrLockName );    }touch_end( integer vIntTch ){        llWhisper( 0, llDetectedName( 0 ) + " tries to open the lock..." );        string vStrTemp = llGetObjectName();        llSetObjectName( "Lock" );        llRegionSayTo( llDetectedKey( 0 ), -1, "Keys Please" );        llSetObjectName( "key" );        llSetTimerEvent( 2.0 );    }    listen( integer vIntChn, string vStrNom, key vKeySrc, string vStrMsg ){        llSetTimerEvent( 0.0 );        llWhisper(0, llKey2Name( llGetOwnerKey( vKeySrc )) + " has the right key!" );        //-- do whatever you need to do to open/unlock the item here    }        timer(){        llWhisper( 0, "... but doesn't seem to have the right key (must be worn)" );        llSetTimerEvent( 0.0 );    }

 Rotation or size or position don't really matter here - apart from the limitations that communication functions used define.

[AerolKnight Moonites]

Mm, still seems to say syntax.. I don't think scripts like me very much.....

[Darkie Minotaur]

The very last } at the end got lost when I copied and pasted it.

[AerolKnight Moonites]

Yay! That worked, tank you very much.... *Now to design a chest or so.. btw, does it matter about prim sizes/parameters or rotation?*

[Darkie Minotaur]

 Rotation or size or position don't really matter here - apart from the limitations that communication functions used define

[AerolKnight Moonites]

Cool, btw, I can use it with a script that gives objects our as well like a coin or something? I can do the chest and key myself, just needed help with the scripting.

[AerolKnight Moonites]

The freebie one I found that was no perms had the chest lid open as soon as you wore the key and it gave an object, what I'm wondering is how would u incorporate that into the scripts?

[Void Singer]

fixed typos above (this is what I get for posting code on the fly, sorry)

any actions you want the lock item to take would go where the comment "//-- do whatever you need to do to open/unlock the item here" is in the lock script.

unfortunately whatever action is going to specific to the object that it's in, so I don't have a good way to guess.

I can say that llGiveInventory is the simple to use, and you should have no trouble figureing out how to insert just there =)

[AerolKnight Moonites]

Thanks, ya the give intentory one shouldn't be too hard, it's the getting the chest lid to open when I wear the key/attach it..

[Void Singer]

you might take a look at the simple hinge action script I  posted   RE-posted in the Library, as it might work for your needs

[AerolKnight Moonites]

Thanks, I shall take a look at that one. ^^
