How to > sidescroller minimap


i would like to make sidescroller minimap, that would kinda work like skyrims compass only on in a 2,5d world. What i would to Archive is that you basicly see target points like houses an pedestrians if you are near to them, which have ofc individual icons. But i dont know where to start nor how to set this up. So does someone know where to find tutorials to this kind of compass or have something similiar to it to share? Would appreciate it.
