[ARK] Summary of dinosaur AI and base behavior that changed in ASA | Causes and countermeasures for failure in ASE sense

ARK: Survival Ascended (ASA) has not only changed its appearance, but also the dinosaur AI, behavior, and processing specifications have changed in detail.

Therefore, if you play with the same feeling as ASE (old ARK),

• Dinosaur suddenly gets caught
• Defense has stopped working
• Increased number of abandoned accidents

There are more and more situations where I feel this way.

This article explains
Changes in AI behavior unique to ASA and
How to operate bases and dinosaurs accordingly .

Assumptions of problems that are more likely to occur with ASA

With the adoption of Unreal Engine 5 in ASA,

• Hit detection is now more accurate
• Increased unevenness of the terrain
• Dinosaur collision detection is now stricter

As a result, the environment is
“easier to get caught than it appears.”

---

Change 1: Dinosaur hit detection has become more severe

Phenomena that are likely to occur

• Stops at a small step
• Caught on the corner of a building
• Stops working due to crowded arrangement

Differences from ASE

Even if you can pass through the gap in ASE,
It will be completely blocked by physical judgment in ASA.

対CE

• Allow sufficient space for passages and gates
• Increase the distance between buildings
• Do not place dinosaurs on top of each other

---

Change ② Unevenness of the terrain strongly affects AI

Phenomena that are likely to occur

• Following is interrupted
• Defense dinosaur does not come forward

Reason

In ASA, the polygons of the terrain are fine, and
subtle slopes and steps also affect AI judgment.

対CE

• Thoroughly leveled the area around the base
• The defense line is completely flat
• Does not rely on natural terrain

---

Change ③ Although enemy search and reaction behavior became stable, accidents also increased

Phenomena that are likely to occur

• React to strange enemies
• Unintended attraction

Reason

Now that the enemy search judgment has become clearer,
laxity in setting the range will directly lead to accidents.

対CE

• Defensive dinosaurs narrow the enemy search range
• Do not place it in a position with a difference in height

---

Change ④ Processing tends to become slow when left unused

Phenomena that are likely to occur

• Destructed while left unattended
• The situation worsens when logging in

Reason

• Increased processing load due to UE5
• Many dinosaurs and buildings

対CE

• Reducing base size
• Carefully selected number of dinosaurs
• Complete separation of defense and work

At ASA,
quality is more important than quantity .

---

Change ⑤ “Easy to get lost” of tracking AI increases

Phenomena that are likely to occur

• Group following collapses
• One character is delayed

Reason

As route search has become more precise,
simultaneous tracking of multiple objects has become unstable.

対CE

• Followers are the elite few
• Individual operation for long-distance movement
• Following off within the base

---

Basic rules for base design for ASA

• Completely leveled land is required
• Wide, simple, flat
• Divided into areas by dinosaur size
• Defensive dinosaurs are fixedly placed

A design that is one step more severe than ASE is required.

---

Operation checklist to reduce accidents with ASA

• Are the corners and gaps in the building wide?
• Are you crowding the dinosaurs
• Is the enemy search range of the defense dinosaur appropriate?
• Have you checked the behavior once before leaving it unattended?

---

Summary: ASA is “an ARK that does not tolerate sloppy operation”

In ASA,

• Hit detection
• Terrain
• AI motion

As everything has become more precise,
laxity in creating the environment can quickly become a problem.

Rather than increasing the number of dinosaurs,
creating bases and layouts that are easy to move is a shortcut to a stable strategy.
