llSetLinkPrimitiveParams - PRIM_SIZE Problem

[Maxx Deischer]

Hello all,

I have the following code:

float up = 0.01;

default
{
    touch_start(integer total_number)
    {
		if (up < 0.49)
		{
			llSetLinkPrimitiveParams(2,[PRIM_SIZE,<0.49,0.49,0.01+up>]);
			up = up + 0.01;
		}	
		else
		{
		llOwnerSay("Full");
		}
    }
}

Works good, but a problem:

The Linked Prim is a cylinder. If I click on prim 1, prim 2 resizes on the z-axis +0.01 and -0.01. I know I can get the position with llGetPos, but I can´t click the child prim, so i have to click prim 1 to resize prim 2.

How can I do that ?

Thanks for help.

Maxx.

try using llDetectedLinkNumber

However, the way you have it written, it won't know if the prim has reached its maximum size, it will count up no matter which link is touched. you may need to get the link size and compare it to the max size you want for that specific prim (or global max size if they're all going to have the same max size)

I'm sorry, but I can't understand the question at all.   

If you're asking about not being able to toucn the child prim, the answer is that you should be able to unless there's another script already in the child prim containing a touch event.   If there isn't, then the script in the root prim should register touches to the child prim (and if there's more than one child, you can use llDetectedLinkNumber(0) to find out which child prim was touched.

However, you also talk about the difficulties in determining the position of the second prim.   llGetLinkPrimitiveParams(2, [PRIM_POSITION[)  should tell you what you need to know, though I suspect you might find PRIM_POS_LOCAL more useful, depending on exactly what you want to do with the measurement).

You probably know this trick and have rejected it since won't work for your build, but when I'm resizing stuff on the z axis, I often find it easiest to set the prim's slice to 0.5 so I don't need to worry about repositioning it.

ok ok, to be more presicse:

I have one Mesh Prim (root) and two others:

A tube (1) and and something in in the tube(2)

the script is in the tube(1) because i can´t click then tube(2)

The tube(2) resizes well, but with z -0.01 and +0.01. So it moves in the ground 0.005 and up 0.005.
I just want it to move up 0.01. 

Thats the true problem.

If I use llGetLinkPrimitiveParams(2, [PRIM_POSITION[) I get always the position of the root prim and not of the child.
i tried this already.

I´ve got no problem with resizing the child or to get the child, but the child resizes up and down 

[Ruthven Ravenhurst]

ok, now I understand better. are there other prims in the link set that you do NOT want to resize? If not try looking at llScaleByFactor along with llGetMaxScaleFactor and llGetMinScaleFactor

[Maxx Deischer]

I only want to rezise the child prim 2 and only in the z axis +

Assuming this prim can't be a simple cylinder for some reason, then perhaps try the PRIM_POS_LOCAL parameter.

If it can be a cylinder, then Innula's suggestion of slicing it in half so it only scales in one direction makes this all vastly easier.
