Using gold in a filter...

[Bob_The_Mighty]

Is there a way of using gold in an event filter?

I want characters to be able to buy special weapons, but i need some way of disallowing the event if they don't have enough money...

Any ideas?

the if command can't work ?

Store the side's gold into a variable, and then check for the value using an [if]. Units don't have gold, so it wouldn't make much sense in a filter (unless you had side filters in addition to unit filters).

Ok, well I've got the gold bit working.

However, it doesn't actually change the unit's weapon stats.

Can someone set me straight?

It is a MP scenario, and I've tried it on both 1.0 and 1.1.7.
Don't work on either.

I'm a bit hazy on the store tag, so it's probably something to do with that.

anyway this is what I have:


[event]
name=moveto
first_time_only=no
[filter]
x="6"
y="61"
side="1,2,3,4,5"
[/filter]

[store_unit]
variable=shopper
[filter]
x,y=6,61
[/filter]
[/store_unit]

[store_gold]
side=$shopper.side
variable=gold
[/store_gold]

[if]

[variable]
name=gold
greater_than=39
[/variable]

[/if]

[unstore_unit]
variable=shopper
[/unstore_unit]

[/event]

[zookeeper]

The problem seems to be that you're storing the unit (which by default also removes it from play) and unstoring the unit only after trying to apply the [object] - but you can give an [object] only to a unit that exists in the field, so it never applies to any unit. So what you need to do is add a kill=no to the first [store_unit] and remove the [unstore_unit] at the end (you still need the [store_unit] to get the unit's side). Then, make sure that range=short is range=melee when playing with 1.1.7 (there the default ranges are melee and ranged, not short and long).

Actually, you could even remove all the storing of the unit as well, since you could just use the variable $side_number instead of $shopper.side (both ways should work).

I went for $side_number and it works a treat.

Thanks a lot.
