making 3 currencies

[lifesontheline]

is there anyway i could make food be a currency like gold and wood?

You can't make one that appears in the top bar like gold and wood do, but you CAN make it exist. You have to come up with your own way of displaying it though.

To make the actual currency, use an array.

Click the Variables button (Looks like a yellow X) in the trigger editor. Click the green +X button to add a variable. Title it whatever you want, I'll use "iPlayerCurrency" as an example. Set the type to Integer, check the Array box, and make it size 12. If you're gonna use the neutral players too, set it to 16. If you're making a Frozen Throne map then it doesn't really matter because the game will resize it automatically. Leave the default at 0.

To get a player's currency, just select iPlayerCurrency from the Variable pulldown menu in anything that needs an integer value, and it'll automatically make a part that looks like "[ Index ]"

Click Index and set it to:
Function: Player - Player Number
Then, set the player part to whichever player you need.

To ADD currency, use:
Set Variable
_ iPlayerCurrency
_ _ [ Player - Player Number (PLAYER) ]
_ Arithmetic
_ _ iPlayerCurrency
_ _ _ [ Player - Player Number (PLAYER) ]
_ _ +
_ _ AMOUNT TO ADD


To SET currency, use:
Set Variable
_ iPlayerCurrency
_ _ [ Player - Player Number (PLAYER) ]
_ NEW AMOUNT

sorry im not really good with variables but i have had experience with them but anwyways what is the variable pulldown menu? is that the same as clicking on the yellow x?

Well, I just realized, you'd need to do more stuff to make your new currency required for unit creation.


You're going to need several triggers and a bunch of things set by hand to do it.

But anyway, first things first....

what is the variable pulldown menu?

When you're making a trigger, some things take integers (a.k.a. non-fractional numbers), like for example, if you create an action with "Player - Set Property", then the last number in it (the value to set the property to) is an integer. If you click that, then you get 3 options:

Variable, Function, or Value.

Next to the Variable option is the pulldown menu that lets you select one of your variables to use it.




Now then, to actually make your currency factor in, you will NEED the expansion, because RoC doesn't support variable-sized arrays or multi-function Fors/Conditionals, which are needed for this.


The most tedious part of all this is you need to enter each unit type and cost by hand, and keep it up-to-date so the currency is handled accurately.


Create 5 new variables:
utRestrictedUnitTypes : Unit-Type, Array, size 1
iRestrictedUnitCosts : Integer, Array, size 1
iRestrictedUnitCostsGold : Integer, Array, size 1
iRestrictedUnitCostsLumber : Integer, Array, size 1
iRestrictedUnitCount : Integer, default 0

Create a new trigger like this:

(Events)
| . Map Initialization

(Conditions)

(Actions)
Set Variable
| . iRestrictedUnitCount
| . Arithmetic
| . | . iRestrictedUnitCount
| . | . +
| . | . 1
Set Variable
| . utRestrictedUnitTypes
| . | . [ iRestrictedUnitCount ]
| . UNIT TYPE GOES HERE
Set Variable
| . iRestrictedUnitCostsGold
| . | . [ iRestrictedUnitCount ]
| . UNIT TYPE'S COST IN GOLD GOES HERE
Set Variable
| . iRestrictedUnitCostsLumber
| . | . [ iRestrictedUnitCount ]
| . UNIT TYPE'S COST IN LUMBER GOES HERE
Set Variable
| . iRestrictedUnitCosts
| . | . [ iRestrictedUnitCount ]
| . UNIT TYPE'S COST IN THE NEW CURRENCY GOES HERE


Copy/Paste those actions and change the unit type and cost for each unit. If a unit does NOT have a value under the new currency, don't include it.

Now you've got a lookup table for the costs of various units.



You still need to restrict building/training using that currency though.

Make 5 new variables:

utUnitBeingCheckedType : Unit-Type
bUnitCheckSucceeded : Boolean
iUnitCheckIndex : Integer
iUnitCheckOwner : Integer
iUnitCancelRatio : Integer



Now, create a new one:

NAME: Check Unit Affordability
(Events)

(Conditions)

(Actions)
Set Variable
| . bUnitCheckSucceeded
| . False
Set Variable
| . iUnitCheckIndex
| . 0
For Each Integer A, Do Action
| . 1
| . iRestrictedUnitCount
| . If / Then / Else
| . | . Unit-Type Comparison
| . | . | . utUnitBeingCheckedType
| . | . | . Equal to
| . | . | . | . utRestrictedUnitTypes
| . | . | . | . | . [ For Loop Integer A ]
| . | . Set Variable
| . | . | . iUnitCheckIndex
| . | . | . For Loop Integer A
| . | . No Action
If / Then / Else
| . Integer Comparison
| . | . iUnitCheckIndex
| . | . Equal To
| . | . 0
| . Set Variable
| . | . bUnitCheckSucceeded
| . | . True
| . If / Then / Else
| . | . Integer Comparison
| . | . | . iPlayerCurrency
| . | . | . | . [ iUnitCheckOwner ]
| . | . | . Greater than or equal to
| . | . | . | . iRestrictedUnitCosts
| . | . | . | . | . [ iUnitCheckIndex ]
| . Set Variable
| . | . bUnitCheckSucceeded
| . | . True
| . No Action


You also need a method to refund stuff that can't build, so here's another:

NAME: Fail Unit Creation
(Events)

(Conditions)

(Actions)
Player - Add Property
| . iRestrictedUnitCostsGold
| . | . [ iUnitCheckIndex ]
| . Conversion - Convert Player Index To Player
| . | . iUnitCheckOwner
| . Current gold
Player - Add Property
| . iRestrictedUnitCostsLumber
| . | . [ iUnitCheckIndex ]
| . Conversion - Convert Player Index To Player
| . | . iUnitCheckOwner
| . Current lumber


Also need one to refund cancelled stuff...


NAME: Cancellation Refund
(Events)

(Conditions)

(Actions)
Trigger - Run (Ignoring Conditions)
| . Check Unit Affordability <gen>
If / Then / Else
| . Integer Comparison
| . | . iUnitCheckIndex
| . | . Equal to
| . | . 0
| . Skip remaining actions
| . No Action
Set Variable
| . iPlayerCurrency
| . | . [ iUnitCheckOwner ]
| . Arithmetic
| . | . iPlayerCurrency
| . | . | . [ iUnitCheckOwner ]
| . | . +
| . | . Arithmetic
| . | . | . Arithmetic
| . | . | . | . iUnitCancelRatio
| . | . | . | . x
| . | . | . | . iRestrictedUnitCosts
| . | . | . | . | . [ iUnitCheckIndex ]
| . | . | . /
| . | . | . 100



Those are just recyclable triggers though, you need 4 more to control item production.

Unfortunately, the only way I can think of to effectively cancel unit training is to kill the unit after it spawns. I'm not sure if they can be cancelled in training, but if they could, then you'd still lose money just by TRYING to build it.
