User talk:Clarknova Helvetic/Clone Primitive v2.0

Hi. There's no CVS or anything for this little project, so this is my attempt to deal with bug fixes and the like in a rational way.

• Title your comments & announce changes with a {{message}} tag and put them in the comments section.

• Make changes to the Beta Code block at the bottom of the page. That way we can track what lines have changed in the page history. Make sure to add your name to the comments :)

Random User Chatter

Have you thought about extending it to do a whole linked multi-prim object? Does llXetLinkPrimitiveParams provide more or less everything needed there? (Except for rezzing and linking the prims themselves of course in the new object hmmm...) -- Dale Innis 14:30, 8 January 2009 (UTC)

Comments

Output code whitespace irregularities fixed and script name in comment header changed to "CLONE PRIMITIVE v 2.31". Migrating to main page. —Clarknova Helvetic 19:04, 9 January 2008 (PST)

previous whitespace fix left a tab-indent escaped, which made the "\t" leak intot he output code. fixed. migrated. —Clarknova Helvetic 18:19, 10 January 2008 (PST)

///////////////////////////////////////////////////////////////////

// // CLONE PRIMITIVE v 2.31 // // // This script chats out lines of text that can be pasted back // into a blank script to clone the original prim. // // It also produces codeblocks optimized for automated transforms. // //

////////////////////////////////////////////////////////////////////

// // HOW TO USE // // // Drag 'n Drop this script into the prim you want to copy. // // It will output a complete script for replicating the object // in Owner-Only chat. Then it will delete itself. // // Copy and paste the chatted script into a *completly blank* // new script // // Then use the Search/Replace function under the Edit menu // to replace the "[HH:MM]  :" line prefixes with a blank. // // Just hit the 'Replace All' button. // // It can take 2 minutes or more to print out, so you may have to // do this a few times. // // // The Primitve Paramaters will be chatted out in the oder that // they're featured on the offical Wiki: // // http://wiki.secondlife.com/wiki/LlGetPrimitiveParams //

///////////////////////////////////////////////////////////////////

// // WHY? // // Chances are you're not going to need an end-to-end // script to dupe your prim. Shift-drag copy is a lot easier. // // But if you're reading this you probably want some of the code, // so carve out what you need from the output. // // The output code is also commented where appropriate. If you want // To know more about what's going on, read the comments here and // check out the wiki. The wiki's good. // // Many advanced items on the grid transform from one object to // another. Builders have used scrips like this to generate the // code that goes into those products. // // Consider the use of both of llSetPrimitiveParams([]) and // llSetLinkPrimitiveParams([]). A multi-prim prim object can be // metamorphed with a single scipt. // // In my experience you can pack five complete primitive trans- // formations into one script before you run out of bytes. //
