 |
|
Hey folks,
Is there a command (or sequence of commands) that makes an NPC stop in its tracks?
My problem is, I want an NPC to walk from A to B. However, an event may occur at any time in between, at which time I want the NPC to stop and do something else. Since the event is player-controlled, I don't know when (or even if) it will happen.
At this point, the only thing I can think to do is this:
| Code: | | walk NPC to(NPC x(it),NPC y(it)) |
However, this is rather clunky, and may cause the NPC to "backtrack" to the tile it is walking off of (if it's walking east or south).
What I really want it to do is finish its walk action to the next whole tile, then do whatever it was going to do.
Any suggestions?
Thanks,
-B |

Perhaps you could walk the NPC one tile at a time, and check whether the event occurs inbetween steps. I'm not sure whether this would allow for smooth movement though.

You can cancel a "walk NPC" command by giving the same NPC another walk command
| Code: |
walk NPC (0,south,10)
wait(random(10,40))
walk NPC (0,south,0)

Metamorphosis did this. Use walknpc with the distance parameter 0. (I'd have to go back and check the script on it, honestly, but I think that does it. The script file is included with the game IIRC.)

| This would make the NPC stop on the tile that it is currently walking onto, it seems. If instead one wants the NPC to stop on the pixel, what could be done? Perhaps changing said NPC's speed to 0...? |

No, it makes him stop where he is. This can muck up your game if used incorrectly, but it is the foundation of the game Metamorphosis, a SoM-style game released before pixel movement was available.

This would ordinarily be a good idea, but in this case I already have a continuously-looping script with a large number of if-then statements. Moving the NPC like this would, I think, simply overwhelm the script. In another application it would work pretty well, I think.

Unfortunately, I need to have tile-based movement for this specific application.
I think I know what I will do. Thanks for the suggestions, guys. |

No, that IS tile-based movement. While he's moving, tell him to walk in that direction with distance 0.
