how can I make prims untouchable ?

Hi,

there is a way to make prims untouchable ?

i.e. I have 2 prims A and B.

- A is in front of B
- A is "untouchable" so if I try to click on A, I'm going to click B

Is it possible ?

thanks

I don't believe this is possible.

inside your touch_start/touch etc. handler, you can use the llDetectedLinkNumber function to find out what prim was touched. So, you can ignore touches, or pretend that another prim was touched if the "wrong" one is detected.

You can do that, if the prims are linked. Put this script in your B prim, the root:

default
{
    touch_start(integer num_detected) 
    {
        if ( llDetectedLinkNumber(0) == 1 ) llWhisper( PUBLIC_CHANNEL, "B was touched" );
        else if ( llDetectedLinkNumber(0) == 2 ) llWhisper( PUBLIC_CHANNEL, "A was touched" );
    }
}

there is a parameter that sets if a child prim forwards a touch to linknumber 1 or not.

Yes it is: llPassTouches( TRUE );
It is set TRUE by default.
If set FALSE the child must have it's own event handler

Surely the OP could simply put a touch event in root prim B and no event in child prim A?

If you mean that the two prims are part of the same object, you can do it as described above with scripts in each object. But also, there's no real need to do it in the simple situation you've described above. You can turn prim A transparent, and then if it is clicked, behave as if the user clicked B, and the user experience will be identical. Of course your real problem is probably more complex than the example but I just thought I should mention that.

Yep, but there was also some earlier concern about script permission requests and all that fun. Whatever this construction is, it seems to be complicated, and the more you wander away from simple devices, the more restrictions LSL piles on your head

Certainly! was it not what I suggested in my first entry?

Suprised that nobody suggested an owner only string. That would make it totally untouchable to the public. Simply anyway.

From the wording of the question it sounds like what the OP wants is to make one prim "transparent" to touches. As far as I know the only way to do that is to use an inside-out sphere (I believe that's a 180-degree twist at both ends). That doesn't make it COMPLETELY transparent to touches, but it makes it so that you actually touch the FAR surface, so any prims on the inside are "closer" as far as touches go.

Yup
I just interpreted a bit ....

Let’s approach this a little differently.

Forget about making “A” untouchable and just have it pretend to be “B”. To clarify, if “A” is touched, it performs the same function as “B”.

Example:

touch_start(integer total_number)
{
    string where = llGetLinkName( llDetectedLinkNumber(0) );
	
    if(where == “A”)
    {
        llSay(0, “B was touched.”);
    }
    else if(where == “B”)
    {
        llSay(0, “B was touched.”);
    }
}
