How to tie Yields to multiple conditions

[Hutoth]

First Post, from a Newbie/ Settler-level Wannabe Modder

I wanted to try to learn the basics of modding, so I made a little plan for something "small" I thought might be interesting, namely:

1. trading posts positioned on a trade route = +1 Gold
2. trading posts not adjacent to any other trading posts or a city = +1 Gold
3. trading posts adjacent to an improved resource = +1 Gold per improved resource.
4. trading posts in general -1 Gold.
(let's forget the "why" of the above, which is irrelevant until I get past the "how")

I believe I know how to make #4 work (so put that at the end, as it seems the easiest to do using a simple <update>

Anyway: I'm evidently doing something totally wrong, and just making up multiple-conditions without defining them or something, but I really have no idea - no background in Dev beyond basic html and hello world

I started out on #1. First, I tried:

<GameData>
<Improvement_Yields>
<Row>
<ImprovementType>IMPROVEMENT_TRADING_POST</ImprovementType>
<RouteType>ROUTE_ROAD</RouteType>
<YieldType>YIELD_GOLD</YieldType>
<Yield>1</Yield>
</Row>
<Row>
<ImprovementType>IMPROVEMENT_TRADING_POST</ImprovementType>
<RouteType>ROUTE_RAILROAD</RouteType>
<YieldType>YIELD_GOLD</YieldType>
<Yield>1</Yield>
</Row>
</Improvement_Yields>
</GameData>


Then I tried:

<GameData>
<Improvement_Yields>
<Update>
<Set Yield="3"/>
<Where ImprovementType="IMPROVEMENT_TRADINGPOST" RouteType="ROUTE_ROAD" YieldType="YIELD_GOLD"/>
</Update>
</Improvement_Yields>
</GameData>

I assume anyone who knows what they are doing with mods will instantly see what's going wrong here. I... do not.

I am thinking that the route "condition" is not properly linked up and I probably have to set up something elsewhere to make this work.

So anyway.. Faced with this initial barbarian horde, I decided to come here rather than wade into obviously violent waters like addressing proximity of other improvements in #2 and #3.

Advice?

Road are not an improvement.. thats all i can tell you for now (without going deeper into the code myself, for which i have no time now), sorry

To make trading posts +1 gold with a road, the code should look like this:

	<Improvement_RouteYieldChanges>
		<Row>
			<ImprovementType>IMPROVEMENT_TRADING_POST</ImprovementType>
			<RouteType>ROUTE_ROAD</RouteType>
			<YieldType>YIELD_GOLD</YieldType>
			<Yield>1</Yield>
		</Row>
	</Improvement_RouteYieldChanges>

This being within your <GameData> and such.

Cheers.

Lets assume this works:
Wouldnt Trading Post then nullify the cost of roads, wouldnt everybody then just build roads on TradingPosts?

roads don't change the tile yield, they're always in effect. this would only help if the tile gets worked.

Thank you so much for that - I went exploring on the database after seeing this, and have got it working and a range of other stuff for my 1st mod now in progress. More of an update soon, but wanted to say Thanks!!! first.
