Problems with Findnearactor

[herejex]

Hi everybody,

I have a problem with the findnearactor function. There is an actor that it's moving (CRANE2), and I want to change its action when it finds a 5991 actor. The code its that:

actor CRANE2
...
ifaction CRANE2ACTION1
{
findnearactor 5991 16 FINDO
ifvarn FINDO -1
{
quote 1
getactor[FINDO].x auxy1
getactor[FINDO].y auxy2
setactor[THISACTOR].x auxy1
setactor[THISACTOR].y auxy2
setvar FINDO -1
action CRANE2ACTION2
}
else
{
move CRANE2MOVE1 geth getv
}
...

The variables auxy1 and auxy2 are defined for every actor. The problem is that the actor CRANE2 never gets the CRANE2ACTION2 action. Is there any mistake with the code?

Thanks!!!

Does it display the quote and move the crane like you specified the code. Or is it only the Action it does not work. It is possible that the actor that uses the findnearactor command never even finds the other actor.

I have the Findnearactor command not clearly in my head right now. But 16 seems an awfully small area to look for another actor.

(While we are on the subject. Does find near actor check whether or not it can actually see the actor. Or does it also find actors that are sheltering behind a wall made out of red lines and thus are out of sight?)

AFAIK, it does find actors behind the walls; and won't work if there are 2 actors picked at the same time; and yes 16 is VERY small, hell even 512 is so damn small. Use 1024 or 1280 to see if your code works.

Apart from that, there's nothing more I can say.

Ok, I tried a lot of tricks but I couldn't find the error. I don't know why findnearactor function doesn't work. I have made a single map an a single con file, HERE, if someone can prove it, I would be very grateful.

Thanks!

I really hate to download stuff to solve a little CON problem. Is there really so much code that you can't post it?

[herejex]

No, there is not so much code, it's just:

gamevar auxy1 0 2

actor 1140
{
	findnearactor 1141 2048 auxy1
	ifvarn auxy1 -1
	{
		quote 30
	}
      else quote 20
}
enda

And the map is a room with the actors 1140 and 1141. I don't know why, but it seems that findnearactor doesn't work. Could be it possible?

[DeeperThought]

Why are you using such a small distance? Also, you can safely delete all of your { and }

Anyway, to answer your question: Assuming that you just posted all of your code, the problem is that 1141 is not an actor, therefore it is not found by findnearactor. Either make it an actor or use findnearsprite instead.

Fixed:

gamevar auxy1 0 2

useractor notenemy 1140
	findnearsprite 1141 2048 auxy1
	ifvarn auxy1 -1 { quote 30 } else { quote 20 }
enda

I highly recommend putting brackets where they can be used, although not where it is 100% pointless.

Ok, thanks for findnearsprite!!!

Why are you using such a small distance?

I use a small distance because the first actor actor is close to the second one, and I wanted to verify that point.

What, you mean like in the example you gave? In CONs, braces are an explicit instruction telling the interpreter to branch, meaning extra braces make your code larger and slower.
