Buoyancy Script for Unity

Bring Your Objects to Life with Realistic Floating Physics!

Create stunning water interactions with this easy-to-use buoyancy script! Perfect for boats, barrels, debris, or anything you want to float and interact with water dynamically. Whether you're building a serene ocean scene or a stormy adventure, this script gives your objects realistic buoyancy with customizable behavior. 🌊

Features

✅ Dynamic Buoyancy: Objects float and respond naturally to water movement.

 ✅ Wave Conformance: Adjusts to water surfaces using Unity's HDRP WaterSurface system. 

 ✅ Customizable Settings: Fine-tune buoyancy strength, damping, and sinking depth. 

 ✅ Easy Setup: Simple to integrate and works with tagged water objects. 

 ✅ Versatile: Works for a wide variety of floating objects, from tiny debris to large ships.

How to Use

Step 1: Attach the Script

• Drag the Buoyancy script onto any GameObject in Unity.
• Ensure the GameObject has a Rigidbody component. If not, add one via Component > Physics > Rigidbody.

Step 2: Configure the Rigidbody

• Enable Use Gravity in the Rigidbody settings.
• Adjust Mass and Drag values to fit your object's size and behavior.

Step 3: Assign the Water Surface

• Use Unity's HDRP WaterSurface or any collider tagged as "Water."
• Drag your water object into the script’s Target Surface field in the Inspector.

Step 4: Fine-Tune Settings

• Factor: Controls buoyancy force strength.
• Damper: Smooths out movement to reduce jittering.
• Sinking: Determines how much the object submerges into the water.

Step 5: Test Your Scene

• Place your object above the water in the scene.
• Press Play and watch it float!
• Adjust settings as needed to achieve the perfect floating effect.

Important: Enable Water Projection

Enable Use Water Projection to make objects conform dynamically to waves and surface normals. This is perfect for creating immersive, wave-driven interactions!  It is required for the buoyancy system to work.
