Mesh Triggers In Unity

While most commonly primitive shapes are used for trigger volumes, it is also possible in unity to use mesh collision to define the shape of a trigger.

Like box collision but meshier

This comes in handy for defining more precise shapes, or especially strange ones that don’t fit with typical primitives. Whether you’re defining the cone of a flamethrower or outlining the shape of a zone border, a mesh to match the shape you need just might be the right option, so long as you have the knowledge or assistance to generate a mesh in the exact shape that you need.
