Openrct2: Add option to create custom currency

[Gymnasiast]

As I mentioned a few times before, I don't want to add many extra currencies to the game. To cater for an audience that wants to use OpenRCT2 in an unincluded, virtual or even fantasy currency, an option should be added to define your own.

If anyone else wants to pick it up, please say so.

Bitcoins!

Would rather want a multiplication system for the currencies to make them more realistic.

For example: 1 $ = 7 kr     NOT like it is right now      1 $ ≠ 1 kr
1 kr is just 0,12 $

That is what makes it unrealistic (for that currency and others) when you have a item for 5 kr (0,60$) and they complain for the high price just because it replaces the $ sign with KR. So instead of just replacing the $ 'letter', multiplying it to the correct value, in this case 1 $ x 7 kr = 7 kr would be appreciated<3 ,
And if 'bitcoins' are added.. which is "1 BTC = 415 $" .. oh boy

@Nubbiy this is deliberate otherwise things to do not get incremented in round numbers such as admission price.

[Nubbie]

@IntelOrca Isnt it just possible to add a multiplying number and then round it to no decimals?

[Ryder17z]

@Nubbiy Kr is different for different countries by the way.

[Gymnasiast]

Exactly. And I'm not going to add virtual currencies like bitcoin, the whole point of this feature is to allow people to use anything (Bitcoin, litecoin, GymnasiastIsAMasturbatingMonkeyCoin) as their currency, with any exchange rate to the pound they want (including insane ones).

@Patrik356b I know, but then it can be called SEK etc

[gDanix]

I'm inspecting the code and this doesn't seems difficult to implement, I think I can do it

[gDanix]

Ok, I think I can show you the progress made with this issue.

Here you can see a new entry for the custom currency, clearly separated from the rest of the "ordinary" currencies:

Whenever you select that dropdown entry, the custom currency configuration window will appear:

Here you'll can configure most relevant aspects of the new defined currency:

Here, the rate is relative to 0.1 GBP. Why?. Because we consider GBP as the reference currency, and it's defined with rate = 10. The text shows 0.1 because a monetary unit is divided by the GBP rate. What you're really doing in this window is setting the rate value and the symbol affix of the custom currency (and in the near future, the symbol too)
