Trick Shot Constant Acceleration

Trick Shot Constant Accelation has a 2D variant for use with Trick Shot 2D: TrickShotConstantAcceleration dynamically composes a 3D “gravity” (or any constant force) vector each frame by summing:

1. World‐space forces (e.g., gravity).

2. Local‐space forces (rotated by the GameObject’s current orientation).

It then assigns that combined acceleration to a sibling TrickShot component, ensuring your projectile always uses the correct constant acceleration—even if the launcher rotates or moves at runtime.

---

Requirements

• This GameObject must have a TrickShot component (enforced by [RequireComponent(typeof(TrickShot))]).

---

Public Fields

Global Constants

• public List<Vector3> globalConstants

  • Forces expressed in world‐space (e.g., (0, –9.81f, 0) for earth‐gravity).

  • Defaults to one entry: (0, –9.81f, 0).

  • Designers can add multiple entries here to combine several global forces (e.g., wind, custom gravity).

Local Constants

• public List<Vector3> localConstants

  • Forces expressed in local‐space, relative to this GameObject’s transform.

  • Each entry is transformed by transform.rotation before being added.

  • Use this to apply forces that should follow the launcher’s orientation (e.g., a “downward” pull relative to a rotating turret).

Usage Example

1. Scene Setup

   • Attach both TrickShot and TrickShotConstantAcceleration to your launcher GameObject.

2. Inspector Configuration

   • globalConstants

     • By default, (0, –9.81f, 0) is present.

     • To simulate a horizontal wind, add (2f, 0, 0).

   • localConstants

     • To apply a downward pull relative to the turret—even if it tilts—add (0, –9.81f, 0) here.

3. At Runtime

   • Every frame, TrickShotConstantAcceleration calculates the sum of all listed vectors and writes it to TrickShot.constantAcceleration.

   • Your TrickShot.Predict() or Shoot() methods will then use this combined acceleration automatically.

Designer Tips

• Multiple Forces

  • Combine wind, gravity, or any other constant fields by adding them to globalConstants.

  • For example, (0, –9.81f, 0) + (1f, 0, 0) applies both gravity and a constant rightward push.

• Local vs. Global

  • Use localConstants when the force should rotate with your GameObject (e.g., pulling “down” toward the launcher’s “bottom” even if it’s angled).

  • Forces in localConstants are transformed by transform.rotation each LateUpdate.

• Overriding Static Values

  • Any constantAcceleration value set directly on the TrickShot component will be overridden in LateUpdate.

  • If you need a fixed acceleration regardless of these lists, disable or remove this component.

• Dynamic Adjustments

  • You can modify either list at runtime via script to change gravity or wind on the fly. Example:

    csharpCopyEditvar accelHelper = GetComponent<TrickShotConstantAcceleration>();
    accelHelper.globalConstants.Add(new Vector3(0, 5f, 0)); // temporary upward thrust
