Culture per science on building

[Starrynite120]

I'm trying to make a building give 50% of your culture as science. This is easy to do with energy to science, but i can't figure it out with culture to science. Could anyone tell me how to do this? I know it's possible easily with a policy, but I want to make it with a building.

It is possible to fake it via lua. Hook into PlayerDoTurn, if they have the wonder get their culture rate and give them half it in science.

 

[Starrynite120]

Ah that would make sense. Is that what you did in your New Horizons virtues for applied Aesthetics?

 

[Machiavelli24]

Yeah, and you can mimic the code from there too. It checks for a player having a specific dummy perk which is given when a player gets the policy. You can have the wonder give the perk.

Presumably a player wouldn't be able to have multiple instances of this building right? Otherwise you'll need a couple extra lines.

Right it's going to be a national wonder for purity

Would you mind taking a look at this code? I'm having trouble getting it to work, and I'm not very familiar with lua. I slightly edited your code from your virtues Mod to this:

function MantleAbility(playerID)
local player = Players[playerID];
local perk = GameInfo.PlayerPerks["PLAYERPERK_STARRYNITE_SCIENCE_FROM_CULTURE"].ID;

if(player:HasPerk(perk)) then
local bonus = math.floor(player:GetTotalCulturePerTurn() / 2);

if(bonus > 0) then
player:ChangeScience(bonus);

-- Send a notification to the player
local text = Locale.ConvertTextKey("TXT_KEY_STARRYNITE_SCIENCE_FROM_CULTURE_NOTIFICATION", tostring(bonus));
player:AddNotification(NotificationTypes.NOTIFICATION_GENERIC, text, text);
end
end
end
GameEvents.PlayerDoTurn.Add(MantleAbility);

Then for the xml I have is this (I don't think there's anything wrong here, but just in case)

<Buildings>
<Update>
<Set Help="Gain [ICON_RESEARCH] Science income equal to 50% of global [ICON_CULTURE] Culture income."
FreePlayerPerk="PLAYERPERK_STARRYNITE_SCIENCE_FROM_CULTURE"
EnergyMaintenance="0"/>
<Where BuildingClass="BUILDINGCLASS_MANTLE"/>
</Update>
</Buildings>

<PlayerPerks>
<Row>
<Type>PLAYERPERK_STARRYNITE_SCIENCE_FROM_CULTURE</Type>
<Help>Gain [ICON_RESEARCH] Science income equal to 50% of global [ICON_CULTURE] Culture income.</Help>
</Row>
</PlayerPerks>

 

[Machiavelli24]

I think it is:

player:GrantScience(bonus);

instead of:

player:ChangeScience(bonus);
----------------
The Help entries should be TXT_KEY_XXX combined with an additional row in the language table. You don't want to be putting your string directly in the perk or building table.

<GameData>
	<Language_en_US>
		<Row Tag="TXT_KEY_XXX">
			<Text>Gain [ICON_RESEARCH] Science income equal to 50% of global [ICON_CULTURE] Culture income.</Text>
		</Row>
	</Language_en_US>
</GameData>

That worked! Great. The only strange thing is the notification just says "TXT_KEY_STARRYNITE_SCIENCE_FROM_CULTURE_NOTIFICATION" instead of saying how much science I'm actually getting. How do I get the notification to display properly?

edit: Nevermind, I figured it out.

 

[Machiavelli24]

Did you add a row to Language_en_US for TXT_KEY_STARRYNITE_SCIENCE_FROM_CULTURE_NOTIFICATION? It should be something like:

+{@1_num}[ICON_RESEARCH] Science from Mantle.

 

[Starrynite120]

Yeah, I just did that and it worked. Thanks!
