altering the "cut" property of prims

I need some pointers on using a script to alter the "cut" properties of prims.

My room is a single cylinder (ie. a single wall) Instead of creating a door, it would be nice just to have the prim cut itself to let me in!

to go from this ----> O to this --->C and hen back to this --->O get me?

any pointers would be apreciated!

You'd need the llSetPrimitiveParams() function to do this.

probably something like this:

float HOLLOW = 0.95; // 95% hollow
vector TWIST = <0, 0, 0>; // no twist
vector TOPSIZE = <1, 1, 0>; // top size same as bottom
vector TOPSHEAR = <0, 0, 0>; // no shear

setStatus(integer status)
{
    float cut_begin = 0.0;
    float cut_end = 1.0;
    
    if(status == OPEN) // otherwise, use the params above: it's closed
    {
        cut_begin = 0.10;
        cut_end = 0.90;
    }
    llSetPrimitiveParams([PRIM_TYPE, PRIM_TYPE_CYLINDER,
                0, <cut_begin, cut_end, 0>, HOLLOW, TWIST, TOPSIZE, TOPSHEAR]);
}

Check out the scripting wiki page on it for more info:

or

float cutEnd = 0.9; //set to your preference - 1.0 is closed, 0.5 is half a cylinder
float HOLLOW = 0.95; // set this to match the same setting in the editor
vector TWIST = <0, 0, 0>; // same as above, match to the editor
vector TOPSIZE = <1, 1, 0>; // ditto
vector TOPSHEAR = <0, 0, 0>; // and again
integer OPEN = FALSE;

default {
     touch_start(integer total_number) {
          if(OPEN == FALSE) { // is CLOSED so OPEN
               llSetPrimitiveParams([PRIM_TYPE, PRIM_TYPE_CYLINDER,0, <0.0, cutEnd, 0>,
               HOLLOW, TWIST, TOPSIZE, TOPSHEAR]);
               OPEN = TRUE;
          }
          else { //is OPEN so CLOSE
               llSetPrimitiveParams([PRIM_TYPE, PRIM_TYPE_CYLINDER,0, <0.0, 1.0, 0>,
               HOLLOW, TWIST, TOPSIZE, TOPSHEAR]);
               OPEN = FALSE;
          }
     }
}

It'd be nice if we could llGet the primitive params and then only modify a certain param instead of all at once. Maybe we can and I'm just not aware of the ability.

all your help is apreciated! perhaps this really IS a community.

DoteDote,

You can get the current parameters with llGetPrimitiveParams().
