Scripts for my garden furniture

Hello, this is my first post so I hope i am posting in the right place. I have just started to build my first objects which are some basic garden furniture. I have been looking for 2 scripts.

The first is for my garden umbrella - I have made an open and closed version - is there a script that would allow my objects to 'morph' from one to the other, giving the impression of opening and closing when touched?

The second is for a garden swing I am making. I would like to put some sit pose balls on the seat and have the sitter experience swinging back and forth.

Any advice or pointing in the right direction gratefully received. Thank you.

Immediate thoughts...

The umbrella could be done with llSetPrimitiveParameters() - changing from one shape to another when clicked on, and swopping textures as it does so.

The garden swing might wait for an avatar to sit on it, and then swing using rotation.

Thank you, I now have my swing script and it works a treat. Just looking for an open and close one for my umbrella. Thank you

The easiest way is to have teh open and closed versions in one object and then just turn off the visibility of the one you dont want to see at this time. Use llSetAlpha and llSetLinkAlpha

The other way, 'morphing' the shape is to make the umbrella canopy change from its furled form to the open form using llSetPrimitiveParams.

Simple Umbrella script

// Code is verbosely commented to help anyone new to LSL understand its operation.
//
vector min = < 0.5,0.5,2.5 >;
vector max = < 3.0,3.0,0.5 >;
float stepsOn  =  5.0;             // Number of Steps to Take between off and on
float stepsOff =   5.0;             // Number of Steps to Take between on and off
vector step;                     // will be set to max/steps (for convenience only)
vector current;                     // Current value
float timesec = 0.5;

SetSize()
{
    llSetPrimitiveParams([PRIM_SIZE, current]);
}

{
    on_rez(integer number) { llResetScript();}         // If we rez in this state reset the script.

    state_entry() 
    { 
        current = min;                    // Set Start Value

        current = min;                                // Current intensity  = minimum intensity
        step = (max-min) / stepsOn;                   // set up step value
        SetSize();
        llSetTimerEvent(timesec);                            // Set the timer going
    }
    
    timer()                                            // Timer event

        SetSize();
        if(current.x >= max.x)                        // If we have reached the target value
        {
            llSetTimerEvent(0);                        // Cancel the timer

        state Rundown;                                // turn it off
    }
}

        current -= step;                            // Decrement the intensity
        SetSize();
        if(current.x <= min.x)                            // If we have reached the target value

            state default;                            // back to the default state
        }
    }
}

Thank you Newgate for this script which I have been playing with. I put it into my furled umbrella and it certainly opened up to state very similar to my opened one. Only thing is that it changes the vertical location of the top of the umbrella so that when it is opened it comes too far down my pole or if I adjust the vertical position of the open position, then it goes too high when closed. I changed the 3rd parameter in 'vector min' to be the same as 'vector max' which made the height ok but the rest of the object becomes much too small when closed. Is it possible in this script to change the size and position of the furled umbrella but achieve the same end result of the open one? Thank you for your help.

Clever, Newgate.

Sarah, you can try a couple of things. In the timer, where it says

timer()                                            // Timer event
    {
        current += step;                            // Increment the intensity
        SetSize();
        if(current.x >= max.x)                        // If we have reached the target value
        {
            llSetTimerEvent(0);                        // Cancel the timer
        }
    } 

You need to add a line like llSetPos(<something here> that moves the umbrella up the pole. You could put it in SetSize() too.

The center of the umbrella doesn't move like it needs to.

When I made my umbrella I made the min and max such that it looked 'ok' in both positions rather than add complexity to the script. I ended up shortening the pole a bit since you cant see muh of it in the furled position anyway.

Modify the llSetPrimitiveParameters to move the position in the z axis.
Not tried this but I think this will work.

SetSize() 
{ 
    vector newpos  = llGetPos();
    newpos.z  -= ((current.z - min.z)/2.0);
    llSetPrimitiveParams([PRIM_SIZE, current, PRIM_POSITION, newpos]); 
}

Ive been looking for a swing myself .....

Theres seems loads and loads of rotate EVERYTHING at various speeds ... but not a lot to swing something.

Martin :L

oh yes there is! try looking here

Sarah, Would you be willing to share this swing script with me and others? I am in need of the same thing.

hey there sarah i would lvoe to get a copy of the swing script from u how much would it cost me ??

thx for yur time reading this
rico

Refer to my reply to Marty's post.

I like that swing / rocker script... is there a way to make it center back up when it is stopped?

hmmm, easiest way would be to capture the 'start' position in default state entry and then simply restore the values.
