Skywalking?

I've seen a couple of people with items that allow them to walk in the air, as the item keeps a constant stream of rezzing platforms underneath them.

I was wondering if anyone that made one of these would be able to explain, basically, how it's done. I can write the code, I think, if only I understood the principal behind it. Does the item rez platforms underneath the owner, or does it anticipate their steps and rez them ahead of time?

I have a fun one made by bUTTONPUSHER Jones. My understanding is it automatically rezzes the watermelon platforms (I customized it) under my feet at regular and rather quick intervals, so if I keep walking, new ones will materialize under my toes. If I stand still however, they'll keep stacking up.

I made one way back then when ElvenGlen opened for group members and had nofly on. It's simple: an invisible cylinder 6m in diameter that follows (non-physical) with a basic sensor-setpos. Make it go to owner's position plus <0,0,-1.2>

Then all you have to do is add particles to make it look like it rezzes things, maybe ?

The one product you are wondering about I wrote.

It is an attachment that rezes new plates in the direction the avatar is moving.

Well, I made one that combines the two ideas. It follows the owner, and rezzes plates 1.2m underneath them. I think, however, that I'm going to use llGetRot to make the plates rez in the direction the avatar is moving, as Strife mentioned he did (but sorry, Strife - I want to make my own). I think that way I can cut down on platform size.

Also, where does 1.2m come from? Wouldn't it be more accurate to take the detected av height and divide it in half?

The 1.2m is from trial and error, since the real height of the AV's waist depends on the legs' length, which you cannot get an accurate measure of through the AV's bounding box.

some tweaking might be in order.

vector t = llList2Vector(llGetBoundingBox(llGetOwner()),0);
float offset = t.z;

This sounds cool. I need me one of them there things. lol

While rezzing a lot of platforms is cool, might it not get fairly intensive on rezzing?

Wouldn't a better solution be to modify a flight script to hover an avatar at a given height (adjustable with up and down) and use a animation overrider to give the appearance of walking even if they are either flying or falling.

hover isn't optimal as it won't work past a certain altitude. And as long as you don't multithread the rezzing you shouldn't have problems with causing excess lag. Course you end up having to simplify the math and come up with short cuts if you rez the plates smartly.

No need. There's a fun, exploitable bug in the avatar movement system for exactly this.

All you really need to do is counteract gravity at the desired height ( read: llSetForce(<0,0,9.8> * llGetObjectMass(llGetOwner())); ). If done right, you can basically walk around in mid-air to heart's content... until you run into an object.


While a bit laggier in terms of rez commands and listeners, Strife's solution is far more user friendly, as one false move with my above command can send you into the stratosphere. Plus, the lag shouldn't be noticable by such a small script as his.

When I said hover, I was not referring to the scripted functions that use the word hover(which I am not fond of anyway). I merely meant 'to stay at one height' (which is optimal when appearing to walk in midair). However you want to script it is fine, I was just throwing the idea out there that you could use alternative means to standing on rez'd platforms.
