Laggy Calls

I am trying to write lag friendly code. Is there a list or does someone know what causes lag the most while scripting. I would like to see kind of what to avoid and a ranking of what kills sims when scripinig.

Sensors have ranked up pretty high imo next to listens. it's best to apply a listen remove as well as llSleep () and llTimer .

anyways those are some things to consider.

How much do sensors need to be used to cause lag? I am sure if your time interval is set to 0.1s then that is an issue. How about every 15 seconds? Also how much do listeners cause lag when not on open chat channel 0.

Thank you for that reference. Read it thoroughly. I have a question about llVolumeDetect now. The article says that if you only need to detect things within 5m then use llVolumeDetect. How would this help? It seems to simply take a normal object, make it phantom while detecting collisions. How does this detect anything outside of itself being collided with as quoted below from the wiki?

"Keep your sensor range as small as it needs to be. If you only need to detect someone's presence within 5m, don't make your sensor radius 90m. (And if your sensor range is only 5m, consider using llVolumeDetect--not a sensor.)"

Because you can rez a 10m invisible volume-detected cube/sphere, which lets you cover a 5m radius space with it.

brilliant! Thank you.
