c - Struct Initialization Error -

i know how initialize structs (generally), i'm having troubles struct within struct stuff

typedef struct location{     uint8_t x;     uint8_t y; } loc;  typedef struct person{     loc location; } person; 

global variables:

static person hero; 

initialization functions:

void initializehero() {     person hero = {0,0, {0,0}}; // compiles     hero.location = {0,0}; // not compile     hero = {0,0,{0,0}}; // not compile } 

your 'this compiles' line correct; that's initialization. other 2 lines don't compile, because they're not initializations, they're assignments. if you're using new enough version of c, use compound literal assignments:

hero.location = (loc){0,0}; hero = (person){0,0,{0,0}}; 

note - person hero declaration in initializehero shadows global variable; don't want that.

btw, missing fields in person? none of should compile you've shown.
