This is a very simple Water Buoyancy C# Script for Unity3D Game Engine,
How to setup
-Add box Collider on Water Body and set it as Trigger. -Also Add “WaterBody” component On it (optionally you can change surface level property if needed) -Give water object Tag as “Water” (or you can change “waterVolumeTag” property accordingly) -Add “Buoyancy” component on a Rigidbody Object that you want to float on WaterBody.
What this Dose
-Rigidbody with “Buoyency” Component floats on “Water” Tagged body. -Check if Rigidbody is inside X - Z bound of Water body and gives force on Y Upwards. -Buoyant force (Upwards force) increases as rigibody dive deep underwater. (can be variable by depthPowerLimit property)
-This is clearly NOT real world Physics, just simple Up force. -No additional forces or drag or waves. -As this component is limited to Y axis buoyancy, make sure your Y is up, however feel free to modify. -Other collider types will work as long as water surface level stay flat, as this is designed on checking collider bounding box. -Rigidbody never fall Asleep if inside water body. -Don’t stack water Bodies on top or duplicate on same location.
