Arthur GC's Hunting Grounds: Prey Overpopulation Control

Description
🦅 Arthur GC's Hunting Grounds: Prey Overpopulation Control 🦅

Hunting Grounds introduces a more dynamic predator system to RimWorld, ensuring better ecosystem balance by spawning predators when the prey population increases.



⠀⠀⠀⠀⠀  🦊 Predators Respond to Prey Overpopulation 🦊

🔹 Dynamic predator spawning based on prey count.
Predators appear when prey populations increase beyond a set threshold.

🔹 Configurable tracking system.
Choose whether to track each prey species individually or as a combined total.

🔹 Natural wildlife selection.
Predators are chosen from the biome’s existing wildlife, ensuring they fit naturally into the environment.

🔹 Season-aware spawning.
Predators will only appear in seasons suitable for their survival.

🔹 On the Prowl.
Predators preferentially spawn near their prey for more authentic encounters.



⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀     🌳 Balanced Predator Selection 🌳

🔹 Size-based predator selection.
Enable an option for predators to match the size of their prey.

🔹 Hungry predators for realistic hunting.
Choose whether predators arrive hungry, increasing their chances of hunting immediately.

🔹 Gradual predator introduction.
Predators spawn over time instead of all at once, preventing sudden ecosystem disruption.



⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀🚨 Alerts and Visual Indicators 🚨

🔹 Spawn alerts for better visibility.
An in-game alert will notify you when new predators arrive.

🔹 Temporary visual markers.
Hover over the alert to temporarily mark new predators with white arrows.



⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀      🔧 Customizable Settings 🔧

🔹 Adjust prey population thresholds.
Set the minimum number of prey required before predators start spawning.

🔹 Control predator numbers.
Define the percentage of the prey population that influences predator spawning

🔹 Manage spawn frequency.
Control how often the game checks for overpopulation.

🔹 Predator spawn limits.
Limit the maximum number of predators that can spawn at once.

🔹 Toggle alerts for immersion.
Option to disable spawn alerts for a more immersive experience.

This mod enhances predator-prey dynamics in RimWorld, making wildlife interactions feel more natural while preventing excessive prey overpopulation.



⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ 🔄 Compatibility 🔄

✅ Fully compatible with biome overhauls, custom animals, and storytelling mods.
✅ Works dynamically alongside vanilla spawning mechanics.
✅ Safe to add or remove from existing saves.
GREAT companion for mods that introduce wild animals' reproduction.



⠀⠀     🔥 Recommended Mods to deal with Boom Creatures 🔥

If you want predators to interact more intelligently with boom creatures (those that explode on death), I highly recommend using these mods alongside Hunting Grounds:

🔹 Predators Hunt Boom Critters – Allows predators to hunt boom creatures without fearing explosions.

🔹 BoomMod or BoomMod Expanded – Boom creatures will only explode on death when the killing blow is a gunshot, burn, another explosion, or they are otherwise on fire at the time. This makes it safer for predators to hunt them.

Balance your world’s food chain and make predator-prey interactions feel more organic with Hunting Grounds!

@Vertigo Which animals on your map have higher population than the threshold you set in the mod settings?

Did you subscribe to mods that allow predators to hunt boom creatures (such as boomalopes)?

The default settings for my mod are 10 prey animals from the same species on the map, so if there are 10+ boomaloopes on the map, predators will start to spawn to hunt them, but they usually do not hunt creatures that explode by default (except if desperate, if I'm not mistaken), hence you need another mod to handle this, as seem in the mod description above.

Also, since the predator needs to be bigger than its prey, I'm not sure if there is anything in the vanilla game capable of hunting bigger animals such as Elephants, but since they reproduce veeeery slowly, this shouldn't become a problem. I believe T-Rexes from some dinosaur mods can hunt Elephants though.

My mod only spawns valid predators: if none is found, none is spawned.

So started to have an issue recently on 1.5. Keep getting bears spawning, yet they are ignoring the prey on the map (VE Animals: Gorillas) and just beelining into my base to setup shop until they are hungry and attacking my colonists/animals.

I currently have 5 bears just chilling right outside my base door right now. While the Gorillas, Elephants, Boomalopes, and Beavers keep expanding their populations. I am wondering if has something to do with Biome Transitions and Tropical Jungles as this is the first time since using this mod to have Tropical Jungles on my map.
Vertigo 3 Jul @ 8:47pm 
Ah yeah that is an issue. I turn off the automatic home zone creation thing. (I forget if that is also a mod or a core feature) Every so often I double check my zone area if I expand in anyway to ensure the correct areas are covered.
Zeress 30 Jun @ 6:32am 
Thanks all figured out the issue and solution. Though that predators unleashed sounds interesting.

The cats thing was really just an example. As it turns out my mistake was not realizing that disconnected zones, in this case Home, can still be pathed to each other. So for example, the cat would wander to the geothermal generator outside the base that is still in "home". I just need to design zones with that in mind.
Vertigo 27 Jun @ 8:03pm 
@Zeress, I suggest limiting the cats and other colony animals that support it to a zone. (Granted I use a mod to get rid of the Pen mechanic) Most commonly I let pets roam the Home Zone while making sure said zone doesn't extend past the outer walls of my base. Of course I also keep a "Animal Hide" zone inside the main base proper when raids/predators are hunting my colony.

@Zeress may I suggest this work of art to keep your kitties safe?
Arthur GC  [author] 13 Jun @ 4:33pm 
Hi @Zeress, I was updating my mods to 1.6 and just saw your message!

Yeah, adjusting predator targeting would definitely be outside the scope of this mod: it’d need to be its own thing. But I have to ask: why are your adventurous cats wandering so far from the base? 😄

What I usually do is set up a safe zone that stays within the base perimeter and assign all my more fragile pets to it. That tends to keep them out of trouble!

One mod that might help is Predators Unleashed. It tweaks predator behavior so they down prey and haul it back to their lair instead of instantly killing it, which gives you a window to rescue your beloved pet before it’s too late.

Hope it helps, cheers!
Zeress 11 Jun @ 6:58am 
I know this is likely outside of the scope of this mod but I figured I'd ask anyways.

Any chance to adjust the odds of predators targeting colony animals? I swear these guys prefer to snipe my cat 80% of the map away over the things the are "meant" to hunt. That's obviously not a you issue and more of base game issue though haha

@Roque the Rogue There are a few, but I think the most popular one is
Wild Reproduction . Even though it doesn't say 1.5, it works fine without issues.

RimKeeper - Wild Animal Procreation is another one.
Roque the Rogue 25 May @ 11:41am 
It boggles my mind RimWorld still requires mods like these to perfectly simulate ecology, now only to find a appropriate animal reproduction mod
