BallisticSolutions

Ballistic solutions for moving targets: interception time, position, and firing velocity, accounting for projectile and target acceleration.

Quickstart

1. Install the addon.
2. Compute the vector to the target:

   var to_target = target.global_position - global_position
   

3. Call BsVelocity*D.best_by_speed to get initial projectile velocity.
4. Instantiate your projectile and assign velocity.

Warning

Godot Physics Consideration:
Godot applies linear damping to physics bodies by default, which gradually reduces object velocity. This can significantly affect ballistic accuracy if not properly accounted for.

Recommendations:

• Set default_linear_damp = 0 in the project settings, if you want pure projectile motion
• Test thoroughly with your specific physics settings

Contributing

• Contributions are welcome. Open an issue or PR.
• Demo scene is included for testing. Run it in Godot to validate behavior.

How it Works ?

• The library sets up an interception equation between target and projectile motion and solves for t.
• Each positive solution t corresponds to a valid hit time and gives a required initial velocity.
• If no positive solutions exist, interception is impossible with current parameters.
