Trick Shot Constant Acceleration

Last updated
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:
World‐space forces (e.g., gravity).
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.
This GameObject must have a TrickShot component (enforced by [RequireComponent(typeof(TrickShot))]).
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).
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).
Scene Setup
Attach both TrickShot and TrickShotConstantAcceleration to your launcher GameObject.
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.
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.
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:
