User:Naya ryo/Turret tracking visualization

This is the personal draft space for elaborating the idea.

Widget will be avaliable on github or something...

Note: On this page, the terms "orbitting speed" and "orbitting velocity" are used interchangeably. They both refer to the same concept—the target’s movement speed along its orbital path.

Visualization formula derivation

It is recommended to read the Turret_mechanics#Hit_chance section beforehand, as this explanation assumes a basic understanding of turret mechanics.

According to the hit chance formula, we have:

Chance to hit = 0 . 5^{({(\frac{Angular \times 40, 000 m}{Tracking \times Signature})}^{2} + {(\frac{\max (0, Distance - Optimal)}{Falloff})}^{2})}

To visualize this complex formula intuitively, we apply the following constraints to simplify the setup:

The attacker is stationary.^{[Note 1]}
The target is either stationary or moving in a perfect circular orbit around the attacker.
The scenario takes place on a 2D plane.^{[Note 2]}

First, consider the distance term.

{(\frac{\max (0, Distance - Optimal)}{Falloff})}^{2}

This term shows that hit chance decreases the further the target is beyond optimal range. This relationship can be visualized along a 1D axis.

The heatmap of hit chance, from a stationary attacker, tracking an orbitting object.
Note that the orbitting velocity (orange arrow arc) lies within the yellow area of the heatmap, which represents mediocre hit chance.

Next, consider the tracking term:

{(\frac{Angular \times 40, 000 m}{Tracking \times Signature})}^{2}

We can visualize the target's orbiting motion as an arc. The length of this arc over one second represents the target’s orbital velocity. For a given orbital velocity, the angular velocity (how quickly the target moves across the turret’s aim) increases as the orbital radius (distance to the attacker) decreases:

Angular Velocity = \frac{Orbitting Velocity}{Orbitting Distance}

This means, the closer the target is while orbiting at the same speed, the harder it is for the turret to track.

From this, we can interpret the turret's tracking stat as a kind of "maximum allowable angular velocity" it can handle. Visually, this forms a 2D cone shape where hit chance remains high within the cone and falls off outside of it.

By combining the 1D distance-based falloff term with the 2D angular velocity-based tracking cone, we can visualize the hit chance on a 2D plane using a heatmap.

^ If the attacker is moving, we can treat it as stationary by adding its velocity to the target instead. This doesn't change the relative motion.
^ This can be easily generalized to 3D.
