Hello everyone,

first post here, please be gentle :)

tl:dr  ->  How do I check if an undiscovered guardian curiosity is present on a planet?

long version:

I'm working on a mod build around guardians. The Idea is to add a some technologies and improvements to give guardians more meaning than just accidentially being present in a system. I also want to make guardians accessible to everyone - either by having the trait (guardians will provide full benefits) or after researching a 3rd. tier tech. I'm at a point where most things work like i want them to, however I'm struggling with the guardian curiosity: 

I want to add a feature that eventually allows you to "grow new guardians" on planets that don't have a guardian yet.

In order to do so, I've added a technologie that unlocks "guardian seedlings" as a new terraforming option (provided you have the guardian affinity).

the terraforming definition looks like this:

<PlanetTerraformationDefinition Name="PlanetTerraformationEndlessGuardiansCreate" SubCategory="PlanetTerraformationDust">

<Cost ResourceName="SystemProduction">560</Cost>

<TechnologyPrerequisite UnlockHidden="true" Flags="Technology,Prerequisite,Discard">EndlessGuardiansTraitTech1</TechnologyPrerequisite>

<PathPrerequisite Flags="Prerequisite,Discard">!PlanetAnomalyGuardian</PathPrerequisite>

 <SimulationDescriptorReference Name="PlanetAnomalyGuardian"/>

<RemovedType>PlanetAnomalyGuardian</RemovedType>

<PopulationEvent Name="PopulationPoliticalEventGuardianAwakened"/>

</PlanetTerraformationDefinition>

This works fine, however if there is an undiscovered guardian curiosity present on a planet it is possible to "terraform" first and discover the curiosity after - which leads to double guardians.

Therefore I would like to suppress the terraforming option if there is a guardian curiosity still present on the planet. I would like to check for "Curiosity_PlanetAnomalyGuardian", however doing something similar to  "<PathPrerequisite Flags="Prerequisite,Discard">!Curiosity_PlanetAnomalyGuardian</PathPrerequisite>" doesn't seem to work since there are no simulation descriptors for curiosities and I'm not even sure if they would be a child / member of "ClassPlanet".

Is there any way to do this?

Edit: also, is there an easy way to format xml code in forum posts, to improve readability?

Thanks in advance!

If you're worried people might abuse the system and get more than 1 guardian on a planet, keep in mind you can move around guardians using a bug with the auto-governors, so you might want to think of another solution for your mod (for example you could make it so that stacking guardians is undesirable, by making their effects not stack).
