Get your position and construct a feature map

Hi All,
Imaging I’m in a 3D world with a terrain, I would like to cover some areas like water, and some places like floating places, where I want my player to crash in those areas, how would I build like a feature map or a crash map ?

Crash into… what exactly? Sounds like you need to create an object with a mesh collider to mark out your “crash areas”, and then make them invisible by disabling the mesh renderer.
