Problem with foreach

@rogercooper

@wc_sumpton would be the one to ask. I still struggle with foreach myself

RogerCooper

@beelee I have used foreach successfully before.

I have as well just not always Just pinging wc so he'll see it

Why "players" when this will be the same as "attachTo"? Just a question?

"GameParseException: Attachment has invalid variables in foreach: $Major_Power$" usually means one of the variables are wrong. Could be a miss spelling. So, recheck there. Beyond that it's hard to tell with the information given. Sorry.

Major_Power

After further review, your problem may be the "_". Instead of "Soviet Union", there is "Soviet_Union". The "attachTo" (and "players") must be the actual player name. If there are both, player "Soviet Union" and "productionSoviet_Union" then you will need two variable lists and they will need to be separated by the carrot "^" and not the colon ":".

There could be other problems, but without more information, I'm just shooting fish in a barrel.

It turns out that the production frontier was misnamed. However, fixing that did not resolve the issue. I am now using "Soviet_Union" in all places

I was copying existing code. If I understand correctly, "attachTo" is arbitrary and "players" is required to be sure that the correct player is involved.

@rogercooper I tried simplifying the situation.

<variable name="Major_Power">
      <element name="United_States"/>
</variable>

    <attachment foreach="$Major_Power$" name="triggerAttachmentsubmarine1United_States" attachTo="United_States" javaClass="games.strategy.triplea.attachments.TriggerAttachment" type="player">
      <option name="conditions" value="conditionAttachmentEveryTurn" />
      <option name="purchase" value="submarine1" count="1" />
      <option name="players" value="United_States" />
      <option name="chance" value="1:20" />
      <option name="chanceIncrementOnFailure" value="1" />
      <option name="when" value="before:United_StatesPurchase" />
      <option name="productionRule" value="productionUnited_States:buysubmarine1"/>
      <option name="uses" value="1"/>
    </attachment>

This gets the error. If I remove **foreach="$Major_Power$" ** the error disappears. (I also tried without the underscore to no avail). I also tried removing every option in trigger.

Here is some code that definitely does work

    <attachment foreach="$LandArea$" name="triggerAttachmentZombiesrussianZombie@LandArea@" attachTo="Zombies" javaClass="games.strategy.triplea.attachments.TriggerAttachment" type="player">
      <option name="conditions" value="conditionAttachmentEveryTurn" />
      <option name="placement" value="@LandArea@:zombie" count="1" />
      <option name="players" value="Zombies" />
      <option name="chance" value="2:70" />
      <option name="when" value="before:russianPurchase" />
    </attachment>

@rogercooper SOLVED IT. I forgot the variableList tags.

If "players" is used, then "attachTo" is ignored. I only use "players" when the trigger affects more than one player. But to each his own.

Would have never guessed this! Happy you have figured it out.
