opening a hatch

I'll post this in the building forum as well, but does anyone know how to make a prim morph from one shape to another without using Edit? What I need is for a solid ship hull (sphere shape) to open a hatch (dimple one end) via chat or touch command.

I have two options in mind, actually change the shape of the object or to switch between a solid visible hull and a phantom transparant hull. Any suggestions?

Yes, that the answer, although they do appear to have broken this so your milege may vary

what do you mean broken?

I'd change the shape of the prim rather than turn it phantom, because you can't link phantom prims to non-phantom ones, and you probably don't want to turn the whole ship phantom if you can avoid it (or people will fall through the floors).

The function you want to look at is llSetPrimitiveParams. That lets you set by script a wide variety of prim properties. If you take a look at http://lslwiki.net/lslwiki/wakka.php?wakka=llSetPrimitiveParams it gives you a very detailed breakdown of how to specify them all -- you give the script a list containing as many or as few properties as you want.

Try something like this to toggle the dimples at each end of a hollow sphere. I don't think it's quite the effect you want, but it should give you something to start from:

integer toggle; // binary value to switch between dimple and no dimple
list no_dimple =  [
PRIM_TYPE, PRIM_TYPE_SPHERE, 0, //a sphere, with the default hole shape for that type of prim
< 0.00000, 1.00000, 0.00000 >, //cut starting at 0 and ending at 1 (not cut, in other words)
0.95, // .95 hollow
< 0.00000, 0.00000, 0.00000 >, //no twist
< 0.00000, 1.00000, 0.00000 > // dimple starts at 0 and ends at 1 (no dimple)
] ;

list dimple =  [
PRIM_TYPE, PRIM_TYPE_SPHERE, 0, 
< 0.00000, 1.00000, 0.00000 >, 
0.95, 
< 0.00000, 0.00000, 0.00000 >, 
< 0.3, 0.72500, 0.00000 > //as before but now the dimple starts at 0.3 and ends at 0.725
];


default
{
    state_entry()
    {
        llSetPrimitiveParams(no_dimple);//start with no dimple
    }

    touch_start(integer total_number)
    {
       toggle=!toggle; //flip the value of toggle each time you touch the prim
       if(toggle){ //if toggle is true
           llSetPrimitiveParams(dimple); //apply the dimple list of parameters
        }
        else{ // if it's not true
            llSetPrimitiveParams(no_dimple); //apply the no_dimple list
        }
    }
}

ok Its not as big a break as I thought, but

If you want to mess with things by script, don't use slice, because it will reset as soon as you alter anything by script.



Going back to the original problem, I don't think this is the way to go, any change is going to unseat everyone. Why not just build a hatch ?
