Development Forum Critter hit script    Malkin    Manager     10/3/2011 I'm developing a critter hit script and I was hoping to get some opinions as to whether it's in the most efficient format. This part makes the agent jump a little when it's hit: scrp 2 15 10854 3 setv va00 rand -10 10 setv velx va00 setv va00 rand -10 -1 setv vely va00 This part reduces pain, fear and anger in the creature that hit the critter. inst doif from <> null targ from doif crea targ = 1 * REDUCE Pain, Fear and Anger! driv 0 -0.45 driv 10 -0.35 driv 12 -0.35 endi endi endm Any thoughts? My TCR Norns   Prodigal Sock Ghosthande     10/3/2011 Hmm, it also works to do it like this: scrp 2 15 10854 3 setv va00 rand -10 10 setv va01 rand -10 -1 velo va00 va01 Kind of a minor change though.   AquaShee   10/3/2011 velo rand -10 10 rand -10 -1 More changes! Other than that, I the script looks fine. The Community Scribble: make (y)our own metaroom!   Prodigal Sock Ghosthande     10/3/2011 lol, yeah, that's the next step...   Malkin Manager     10/3/2011 Thanks! Is there any way to make this step more efficient? doif from <> null targ from doif crea targ = 1 My TCR Norns   Prodigal Sock Ghosthande     10/3/2011 hmm... doif from <> null doif crea from = 1 endi but you're adjusting drives right after that, so you'd have to 'targ from' anyways. So maybe replace the whole sequence with something like this? inst doif from ne null doif crea from eq 1 sway writ from 0 -0.45 10 -0.35 12 -0.35 -1 -1 endi endi endm (I can't remember for certain that "-1 -1" is appropriate but that's how 'urge writ' handles it and I assume it's probably the same.)   Malkin Manager     10/3/2011 So the -1 business is just to say 'nothing's happening here, move along'? I wish the help guide had that in it! scrp 2 15 10854 3 velo rand -10 10 rand -10 -1 inst doif from ne null doif crea from eq 1 sway writ from 0 -0.45 10 -0.35 12 -0.35 -1 -1 endi endi endm My TCR Norns   Peppery One Papriko   10/4/2011 Why don't you directly use CREA? doif crea from = 1 sway writ from 0 -0.45 10 -0.35 12 -0.35 -1 -1 endi In case FROM is NULL, we still don't get any problems, since NULL is not a creature. Yes, CREA has a NULL-Agent-Handling. I tested it ingame. outv crea null 0 Lets play plants! Photosynthesis... Photosynthesis... Photosynthesis...   Malkin Manager     10/18/2011 velo rand -10 10 rand -10 -1 inst doif from ne null doif crea from = 1 sway writ from 0 -0.45 10 -0.35 12 -0.35 -1 -1 endi endi endm Is that right? Or are you trying to say that the first doif checking that from actually IS, could not have to be there? My TCR Norns   Peppery One Papriko   10/19/2011 Okay, I gonna try to explain it once more: doif from ne null doif crea from eq 1 sway writ from 0 -0.45 10 -0.35 12 -0.35 -1 -1 endi endi Here you first check if FROM actually exists at all with the first line. In case it exists you go to line two where you check if FROM is a CREA. doif crea from eq 1 sway writ from 0 -0.45 10 -0.35 12 -0.35 -1 -1 endi This saves you one DOIF and accordingly some time used to execute your code. Instead of checking if your FROM exists and only looking up whether it is a creature or not, you only check if it is a creature. When FROM is a NULL agent, then it obviously can not be a creature, so the second piece of code does the same job faster. Maybe you should ask someone else to make it a bit more clear, I can not explain that awesomely... Lets play plants! Photosynthesis... Photosynthesis... Photosynthesis...   AquaShee   10/19/2011 While Papriko is right, there's even a more important reason to skip the doif FROM eq NULL part: FROM can never be null, since scripts are always called by another agent. (Perhaps not always but I can't think of any example at all) I'm not even sure if it is necesary to check the type of agent at all. "stim writ", a similar command, just does nothing on agents that aren't creatures, so "sway writ" might just do nothing as well without throwing any errors. The Community Scribble: make (y)our own metaroom!   Malkin Manager     3/7/2012 Is there a way to make the chemicals 'silent' using the sway writ command? If you wanted to have chemicals, and have certain amounts, but not have creatures learning from all of them? My TCR Norns   Prodigal Sock Ghosthande     3/7/2012 Do Creatures even learn from chemicals? I was under the impression that in C3/DS they only learned from stimuli.
