How to detect the end of an object?

Question

C++ / C#

Hello, when developing a project, a problem arose. There is a certain platform, it can be either polygonal or square. It is necessary that the function hanging on the character returns the distance to the nearest end (and the coordinates where the cliff is located) of this platform.


As far as I understand, it is possible to make a character's radius and check for the presence of a platform in this radius. But is this the right decision?

Answer 1

It is necessary to calculate through a collision (on what the character stands with himself) and angles.
Nothing extra needs to be attached.
