Aim Prediction Solver

About

A high-precision projectile targeting system that accurately predicts and hits moving targets in Unity. Perfect for tower defense games, and games where AI characters need to fire projectiles at moving enemies.

This system uses advanced ballistic calculations to determine the exact launch angle and velocity needed to intercept moving targets, whether you're launching missiles, arrows, fireballs, grenades, or any other projectile.

Key Features

• Predictive targeting that leads moving targets for accurate hits
• Supports both gravity and non-gravity based projectiles
• Automatically detects NavMeshAgent, CharacterController, and Rigidbody components for velocity data
• Plug-and-play integration with minimal setup required
• Optimized calculations with configurable iteration count for maximum accuracy

Perfect For

• Tower defense games with automated turrets
• Enemy AI that fires projectiles at the player
• And more...

Guide

Basic Setup

Add a MissileLauncher component to your turret or AI GameObject. In the Inspector, assign a Launch Point transform (the muzzle) and a Missile Prefab — the prefab must have a Missile component and a Rigidbody. Set Projectile Speed, toggle Use Gravity to match the prefab's Rigidbody "Use Gravity" setting, and tune Prediction Iterations (3–4 is usually optimal for missiles with short travel times).

Setting Up Targets

The transform you pass to TryLaunchAtTarget is the exact point projectiles will converge on and will also be used to find the velocity carrying component. The recommended setup is to add an empty child object named Target to your enemy, positioned at center mass.

Make the Target a child of the object that has the movement component — a NavMeshAgent, CharacterController, or Rigidbody. The solver reads the target's velocity by searching upward from the aim point through its parents, checking for those components in that order. Deeper nesting under the moving object also works — for example, attaching the aim point to an animated bone so it follows the animation. If no movement component is found above the aim point, the target is treated as stationary.

Firing at a Target

Call TryLaunchAtTarget whenever you want to fire. It reads the launcher's Inspector settings, computes the firing solution, and spawns/launches the missile in one call:

public class Turret : MonoBehaviour
{
    private MissileLauncher missileLauncher;
    public Transform targetPoint; // the enemy's "Target" child (see Setting Up Targets)

    void Start()
    {
        missileLauncher = GetComponent<MissileLauncher>();
    }

    void Fire()
    {
        bool success = missileLauncher.TryLaunchAtTarget(targetPoint);
        if (!success)
        {
            // Target out of range, or missile prefab is missing a Missile component
        }
    }
}
