Subliminal Messages / Brief Picture flashes

[Love Zhaoying]

It occurred to me, that one could change a prim's texture for a "brief period" and change it back.  And, use this as a "subliminal" message, like was done in the "Fight Club" movie.

Of course, for some users either a) they would "miss" the flash because it doesn't hit their framerate, or b) the flash would be "too long" for the same reasons.

The two methods I thought of are, either:

a) Use llSetLinkPrimitiveParamsFast() to change a texture, then immediately change it back.

b) Use a timer to do the same. More "controllable" but potentially with a less desirable effect.

Any thoughts?

I would only use this for "good", not "evil"!

Use-Case: This would be good for a "creepy build". Make the "flashes" longer and longer, creating a sense of foreboding, and then they finally..

See the monster! 

Which with PBR, could be their own reflection!!!

Slide the texture 'side to side'.    Use llSetLinkPrimitiveParamsFast() to adjust the offset showing only part of the whole texture at one time.  Is 'a prefetching the new image' trick.

Couple it with a proximity sensor for more fun, too.

If you do things too fast in the script (like just calling llSLPPF twice), no object update will be sent to any viewer because nothing will have changed during that server-frame.

You should llSleep for 1/45th of a second between llSLPPF calls to make sure the changes can appear, or use a non-looping texture animation if you want a shorter period for the texture to appear (assuming you had both images in one texture).

People with low framerates will either not see the change at all, or see it for much longer than others.

Yes! I guessed this could happen!
