Projectile Toolkit - Targeting and Trajectory Prediction

Want to implement game mechanics based on projectile motion? Want enemy AI to use ranged weapons such as cannons, rocks or arrows to accurately hit targets? Want to have full control over jump motion of objects in games or animations without losing their physical properties? This toolkit has got you covered!

🎮 Playable WebGL Demos

📚 Documentation

Projectile Toolkit is a physics toolkit that solves two key problems related to projectile motion: targeting algorithms for gravity-affected rigidbodies to hit the specified target, and trajectory prediction algorithms that predict and render the trajectory of a rigidbody.

⚡ Projectile Toolkit is extremly easy to use, and can be quickly integrated into existing projects.

🏆 Features:

- Flexible and Easy to Use, the core API is carefully-designed static methods, can be called directly from your scripts

- Super Fast, most algorithms don't even touch trigonometric functions

- Works in both 3D and 2D, (works in 2D if only your game treats y as up axis)

- Works on all build platforms

- Plenty of inspirational demos (currently 3 demo scenes and 1 game). Great for both learning this toolkit and quick prototyping

- Full source code

- Detailed documentation

🎁 Bonuses:

Useful game toolkits such as:

★ explosion system

★ simple top-down character controller (character movement)

Technical details

-----------------------------

🎯 Targeting algorithms:

Computation of a gravity-affected rigidbody to hit the specified target. Extremely easy to use, you just specify start point, end point, and one of the following:

Computes the launch Velocity by:

- Angle

- Height

- Time

- a coefficient of the quadratic function

- Speed

Computes the launch angle by:

- Speed

(NEW in 1.1) Computes the max range by:

- Elevation and Speed
