user controls - How to make movable character in maze with C++ -
so have maze printed out once user presses 1 in order launch map , other variables. have declared player smiley face or set equal 1. however, make character movable throughout maze having trouble doing so. have created player move space in order move without overwriting other code. thinking of using switch statement , detecting user input , changing x , y positions based on dont know how put in mapcreation function. wondering if guys me generate variables such treasures @ random locations throughout map , if wall or '|' dont print. treasures spawn @ same location. input on of questions help! thank you!
** ignore cases being used dont have use them.
**update if has link somewhere would helpful! thank you!

on windows, can use readconsoleinput() navigate keyboard in windows console. solution checks collision using statement if (maze[player.y][player.x-1]==0) . 0 means no wall, 1 means wall has been hit.
here's example of usage of readconsoleinput().
