Rez Gray Registered User Join date: 2 Apr 2007 Posts: 23	09-01-2008 21:18 Notes for tomorrow when I start coding: //Programming Path Take vehicle, drop at start position, 'save' , move to next waypoint and rotate to face next target, save, edit, save, repeat. Dump results to chat. Save to notecard. Put notecard in object rezzer. Rezzer would ask which route to take, etc. //Path Data [command],<target position>, <vehicle rotation>,<speed> //Commands MOVE\|<target>\|<rotation>\|speed WARP\|<target>\|<rotation> SAY\|"string" - for tours and destination announcements SOUND\|"uuid" - emits designated sound PAUSE\|time GOTO\|step - scrolls back to set step in path RESET - resets to first step in path DIE - deletes the craft.

Seeing as I never relinquished the rights to it, I'll see if I can find the scripts at some point and post it. Then you can use it or take useful bits as you please.

Lear Cale wordy bugger Join date: 22 Aug 2007 Posts: 3,569	09-02-2008 10:24 I have one, that uses "nonphy" move code, that I started for someone who didn't end up using it. Let me know if you'd like the code. No problem letting it go public domain. For mine, you don't get a choice of different routes. No doubt that could be added, doing it by notecard name for example.

Don't worry about human readability, as long as your scripts are easy to set-up it shouldn't matter. However, time wasted parsing strings (especially if you have to use methods like llParseString2List and so-on) is time that your train/vehicle loses when trying to respond. If you can transmit data as integers then it will benefit you as you as Mono is very fast at processing them, the more data you can fit into them the better. Strings should be avoided at all costs IMO except to actually transmit the data (since we have no choice). _____________________ Computer (Mac Pro): 2 x Quad Core 3.2ghz Xeon 10gb DDR2 800mhz FB-DIMMS 4 x 750gb, 32mb cache hard-drives (RAID-0/striped) NVidia GeForce 8800GT (512mb)
Rez Gray Registered User Join date: 2 Apr 2007 Posts: 23	09-02-2008 22:41 Well. I had a decent go at it tonight. I got basic programming and storage working. I'd show off the script but it's ugly as hell and somewhat confusing. A couple of questions. 1. I'd like a smooth rotation from point to point. I have the rotations desired at each point already stored. How would I best be served to make a smooth rotation between start and end, for smooth-ish animation? 2. Barring that. How do I do a 'look at target' and 'autolevel' the craft? Assuming that I want to face the target using the front X-axis? Thanks.

It takes regular rotations (like you'd feed into llSetRot()) but can perform the rotation smoothly. If you have a suitable rotation, that would leave your train rotated correctly then it should be fine I think. _____________________ Computer (Mac Pro): 2 x Quad Core 3.2ghz Xeon 10gb DDR2 800mhz FB-DIMMS 4 x 750gb, 32mb cache hard-drives (RAID-0/striped) NVidia GeForce 8800GT (512mb)

I've already got it working, however I'm trying to add support for "Stops." where it automaticallly pauses for a few seconds before starting up again... Maybe we could work on it as a joint project? _____________________ Life is a highway... And I just missed my exit.
Rez Gray Registered User Join date: 2 Apr 2007 Posts: 23	09-10-2008 22:21 Sure thing. I have running beta code that just records stops an plays back the track. SL's been kicking my arse all week. Drop me an IM.

Rez Gray Registered User Join date: 2 Apr 2007 Posts: 23	10-20-2008 05:27 I have a beta written and loose in the world. It's got a few dodgy bits but it works mostly like I wanted it. I'll be posting it after I get home from work this evening.
Rez Gray Registered User Join date: 2 Apr 2007 Posts: 23	10-20-2008 05:52 The code isn't cleaned up for posting. You can see the current stage at http://postreply.org/viewtopic.php?f=2&t=18 I'll be cleaning it up from work and adding comments.
Debbie Trilling Our Lady of Peenemünde Join date: 17 Oct 2006 Posts: 434	10-20-2008 06:12 Look forward to seeing it, thanks. I have been working on a cross-sim non-physical monorail script for last few weeks. Works well and am currently working on adding "stops". The smooth rotation problem was solved by using "Slerp" (Spherical Linear Interpolation), which I had not heard of until I posted a query of these very forums... This thread proved invaluable, especially posts #11, #13 and #14 /54/3b/50692/1.html _____________________ http://wiki.secondlife.com/wiki/User:debbie_Trilling

It represents the weight of the average between 'a' and 'b'. Presumably (often) if t=0 the result is equal to 'a' and if t=1 the result is equal to 'b'. Values in between will result in some mix of the two, and values outside that range are USUALLY meaningless. There are many other forms of interpolation besides the commonly used straight linear combination of two endpoints though, and the extrema won't always exactly match one of the input points. See http://en.wikipedia.org/wiki/Interpolation
