Ballistic Targeting

BallisticTargeting is a lightweight helper that sits on a GameObject with a BallisticAim component. Every frame (in LateUpdate), it attempts to aim at a designated targetTransform. It exposes a read‐only HasSolution flag indicating whether a valid ballistic solution exists for the current target position. Designers can swap targets at runtime via SetTarget(...).

---

Requirements

• The GameObject must have a BallisticAim component (enforced by [RequireComponent(typeof(BallisticAim))]).

---

Public Fields

• public Transform targetTransform

  • Drag a Transform (e.g., an enemy, waypoint, or moving object) into this slot via the Inspector.

  • The component will attempt to calculate a low‐arc solution to this position every frame.

---

Public Properties

• public bool HasSolution { get; private set; }

  • Read‐only property that returns true if the most recent call to ballisticAim.Aim(...) succeeded (i.e., a valid firing angle exists to hit targetTransform.position).

  • If targetTransform is unset (null) or out of range, HasSolution becomes false.

---

Public Methods

• public void SetTarget(Transform newTarget)

  • Assigns a new Transform to targetTransform.

  • Can be called from other scripts to change who or what this turret should aim at.

  • Example:

    csharpCopyEditvoid SwitchEnemy(Transform nextEnemy)
    {
        GetComponent<BallisticTargeting>().SetTarget(nextEnemy);
    }

---

Usage Example

1. Scene Setup

   • Attach both BallisticAim and BallisticTargeting to your turret (or launcher) GameObject.

   • Assign the turret’s Y‐pivot and X‐pivot inside the BallisticAim component.

   • In BallisticTargeting, drag the enemy’s Transform (e.g., “Enemy1”) into targetTransform.

2. Runtime Behavior

   csharpCopyEditpublic class TurretController : MonoBehaviour
   {
       private BallisticTargeting targeting;
   
       void Awake()
       {
           targeting = GetComponent<BallisticTargeting>();
       }
   
       void Update()
       {
           if (targeting.HasSolution)
           {
               // We have a valid firing solution—enable shooter, show reticle, etc.
           }
           else
           {
               // Out of range or no target—disable fire button or show “no lock”
           }
       }
   
       public void ChangeTarget(Transform newEnemy)
       {
           targeting.SetTarget(newEnemy);
       }
   }

   • Each frame, BallisticTargeting calls ballisticAim.Aim(targetTransform.position) internally.

   • HasSolution updates automatically, so your UI or firing logic can react immediately.

Designer Tips

• Unassigned Target

  • If targetTransform is left null, HasSolution will always be false and the turret won’t rotate. This is useful for “idle” states where you don’t want the turret to seek anything.

• Target Swapping

  • Call SetTarget(...) from other gameplay scripts (e.g., when switching between multiple enemies).

  • If you need a “clear target” behavior, call SetTarget(null) to reset.

• Checking HasSolution

  • Use HasSolution in your HUD to display a “lock‐on” reticle only when a shot is possible.

  • Poll it in Update() to toggle the “Can Fire” icon or disable the fire button if no solution exists.

• Combining with BallisticAim Settings

  • Ensure that initialSpeed, constantAcceleration, and pivot limits in BallisticAim are configured so that targets you want to hit lie within range. Otherwise, HasSolution will be false for unreachable positions.
