# THZ - Treasure Hunter Z
Created by @kts_kettek in response to @eigenbom, THZ is a treasure huntin' "rogue-like" game intended to fit in a single 140 character Tweet. It runs in the browser's developer console.
And what is the objective? To find the buried gold of a forgotten civilization (and maybe reload the page if you can't ;])
Check out the 560 character sequel [here](https://github.com/kettek/THZ-II/)!
## Code (paste in browser console)
z=43;r=new Date%z;onkeyup=function(e){d=1-e.which%4;z+=d%2?d*9:-d-1;m='';for(a=1;a++<53;m+=a%9?a==z?a==r?'$':'@':'.':'\n');console.log(m)}
## Code Breakdown
// player's start position
z = 43;
// randomized gold position, limited to player's start position
r = new Date%z;
// run game loop on each key press
onkeyup = function(e) {
/* Given that e.which returns the keycode, we modulo 4 it to get 4
possible values. We negate this value ( 1 - X ) to save a couple
characters in calculating the change in player position (z) - this
results in up=-1, right=-2, left=0, down=1 */
d = 1-e.which%4;
/* Modify the player's position based on key press. By using
modulo 2 on 'd', our up and down directions become -1 and 1 and our
left and right become 0 and -0. -1 and 1 then evaluate to true, from
which we can simply multiply 'd' by 9 and add that resulting value to
our player position. Since 9 is the width of the map, this moves our
player up or down. If the expression returns false, we simply negate d
and subtract 1 - this returns -1 for left and 1 for right, which can
then be added to the player's position. */
z += d%2?d*9:-d-1;
// Map generation
m='';
/* Here we build the map string. Every step from 1 to 53, we add a
character to the 'm' string. 'a' represents our current tile position
and simply draws a different tile depending on various conditions.
These conditions are: if 'a' == 'r', then '$'; if 'a' == 'z', then '@';
if 'a%9' != 0, then '.'; otherwise line break. */
for (a=1;a++<53;m+=a%9?a==z?a==r?'$':'@':'.':'\n');
// Draw map
console.log(m)
}
## Code rewrite
// player's start position
player = 43;
// randomized gold position, limited to player's start position
gold = new Date%player;
// run game loop on each key press
onkeyup = function(e) {
/* Given that e.which returns the keycode, we modulo 4 it to get 4
possible values. We negate this value ( 1 - X ) to save a couple
characters in calculating the change in player position - this results
in up=-1, right=-2, left=0, down=1 */
d = 1-e.which%4;
// Modify the player's position based on key press.
if (d%2) { // is 'd' -1 or 1? If so, multiply by 9 to move our player up or down
player += d * 9;
} else { // otherwise negate d and subtract 1 and add the resulting value to our player (-1 for left, 1 for right)
player += -d - 1;
}
// Map generation
map = '';
// Here we build the map string.
for (tile = 0; tile < 53; tile++) {
if (tile % 9) {
if (tile == player) {
if (tile == gold) {
map += '$';
} else {
map += '@';
}
} else {
map += '.';
}
} else {
map += '\n';
}
}
// Draw map
console.log(map)
