I think I'm going to get more into C.

c_is_awesome.c

#include <stdio.h>

typedef struct {
    float x;
    float y;
    char* name;
} Player;

typedef void (*PlayerCommand)(Player* player);

void MovePlayer(Player* player) {
    player->x += 2;
    printf("I moved %s, he is now at (%f, %f)\n", player->name, player->x, player->y);
}

int main(int args, char** argv) {
    Player player = {0, 0, "Bob"};
    PlayerCommand command = MovePlayer;
    command(&player);
}
