Learn how to implement procedural bullet spread and gun recoil ๐ฅ into your game with this ScriptableObject-based gun system (Part 2 of the Gun Series!)
In this Unity Tutorial you'll learn how to implement recoil/bullet spread in 3 ways -
1. No spread - always perfectly accurate
2. "Simple" Spread - the most common way you'll find to implement spread, based on random values in a Vector3 Range
3. Texture-Based Spread - sampling a texture to define a "pattern of randomness" based on some texture data. Using this you can get something like the recoil in popular games such as Counter-Strike.
Bullet spread and Recoil are inseparable topics, because the recoil actually makes the bullet spread happen! Learn how to do both in this tutorial!

๐ Projectile Guns
๐ Simple Bullet Spread - Refined in this video
๐ Complex Bullet Spread - Covered in this Video
๐ Reloading
๐ Attachments
๐ Animated Models
๐ Simple Impact Damage
๐ Damage Effects such as burning, freezing, explosions, etc...
๐ And even more!
