Objects Memory Allocation

Ok so i was wondering how much memory is allocated when i make an array of say colliders. Like int is 4 bytes.. collider is of how much memory?

 

The short answer is, it's undefined and you shouldn't worry about it.

The longer answer is: the array itself is probably 4 (but maybe 8, depending on platform and build settings) bytes per entry, plus a small but undefined bit of overhead, as colliders are objects, and an array holds only the object references; so what would really matter is how many of those array entries point to unique objects; and then the actual size of such an object certainly depends on which collider subclass it happens to be, plus whatever under-the-hood (and thus undefined) data structures Unity has associated with it; but whatever it is, it is certain to be absolutely trivial compared to, say, one good-sized texture or sound effect; so you shouldn't worry about it.

 

thanks
i was just worried that I couldn't set a value for my collider array to a high value..

 

A hashset containing terrain meshes (not unity terrain) in a 50,000 unit radius uses up about 4mb in my application, it can be reduces quite a bit..
