CgTalk Maxscript Challenge 009: “BACK TO BASICS: Flickering light”
DESCRIPTION: Create a tool that makes a light flicker like a faulty fluorescent tube. Create animation keys for the flickering.
INTERMEDIATE SCRIPTERS: Provide options for light delay (as in how long the light stays on or off for when not flickering), randomness or periodic flickers (like a strobe), and colour.
ADVANCED SCRIPTERS: Make the tool create an actual fluorescent tube light object, embedded with a standard light. Try using shaders to set up the light instead.
RULES:
[ul]
[li]Code from scratch. Try not to use pre-exisitng functions or plugins.[/li][li]Show your script references, if any (eg. Looking at another script to assist you).[/li][li]You are encouraged to ask for help where needed, but try to do it on your own. The maxscript reference is an invaluable resource.[/li][li]Post your final script inside [/li]“`
tags (located on your posting toolbar).
[li]Post all code into THIS thread.[/li][li]Post the max version you coded in, plus any maxscript extensions you used. (Thanks galagast!)[/li][li]Try to finish the challenge in a week. There is no definite time limit. [/li][/ul] NOTES: After much deliberation, I’ve pulled the challenges down a notch. I’ll start making more simplified assignments that can be easily completed in a week.

This sounded fun so I took a quick stab at it. There is no UI or anything yet and some of the flicker timing needs ajusted. Just select a light and execute this code. By the way every time I try to pose code in this forum it will randomly remove spaces from the script sometimes. Am I doing something wrong?

Just tried it out. Nice work! I like the additional options you threw in.

Nice script.
The web board modifies lines that atre more than 50 characters long. strange but true.

I added a off color and on color to this script, it blends between them based on the multiplier. You also dont need to pick the light anymore I just have it run on anything that is a light in the selection.

I finally found some free time and decided to take part in the challenge. I went a slightly different direction where a mesh is turned into a flickering light object.
Be kind I haven't had a chance to script in max for to many months.

OK so I added in alot functionality to my script over the weekend. I should probably include a help pop up soon because I imagin the tool could get confusing. Anyways, there are a few ways to use it. 1. Select a light change any options you want then hit execute. 2. Select a mesh, then a pop up will show the materials on the mesh. Select any materials you want to affect in the pop up window. This way if you have something textured with materials you dont want to illuminate they wont. You have two ways to set up light creation as well. Either auto create lights or use custom lights. If you select custom you can select lights already in the scene and have them be the flickering light for the mesh. If you choose auto it will create three lights at the angle of the mesh plus more lights between those based on how many lights are set in the extra lights option. When you select the mesh it figures out what the longest length of the mesh is and automaticly selects that option for you. You can change it if it makes a bad choice. I also added undo because when I was testing it was becoming frustrating to not have it. I have a few more ideas but I probably already went overboard.

RyanT: I just tried your script and I have a few suggestions:
[ul]
[li]Consider wiping out the self illum keys on materials that have already been keyed one or more times instead of adding new keys ontop of the existing one, or as you can guess the the light and materials get out of sync.[/li][li]Instancing the lights so it will make it easier for an end user to make edits to the lights.[/li][li]Grouping the lights with the geo would be helpfull for scene manipulation. (I chose to link to the lights to the geo but its the same idea)[/li][/ul] Pretty cool overall though, I like it.

Hey blue,
Thanks for the suggestions. I will have to do that. I thought that having an option to wipe out the keys on the material and lights might be good. Let the user choose if they want to do it or not. Grouping them / linking them is a good idea too.
