117 : Adding transforms
Balthazar:
Put these before the draw() function:
function adjust_health(amount) {
...
}
function set_transform(ctx, obj) {
var x = obj.x - obj.origin_x;
var y = obj.y - obj.origin_y;
// Adjust origin if we're facing left.
if (obj.dir < 0)
x += obj.width;
// Translate origin to (x,y).
ctx.setTransform(1, 0, 0, 1, x, y);
// Flip the image if we're facing left.
if (obj.dir < 0)
ctx.scale(-1, 1);
}
function reset_transform(ctx) {
// Reset transform to the identity matrix.
ctx.setTransform(1, 0, 0, 1, 0, 0);
}
function set_transform(ctx, obj) {
var x = obj.x - obj.origin_x;
var y = obj.y - obj.origin_y;
// Adjust origin if we're facing left.
if (obj.dir < 0)
x += obj.width;
// Translate origin to (x,y).
ctx.setTransform(1, 0, 0, 1, x, y);
// Flip the image if we're facing left.
if (obj.dir < 0)
ctx.scale(-1, 1);
}
function reset_transform(ctx) {
// Reset transform to the identity matrix.
ctx.setTransform(1, 0, 0, 1, 0, 0);
}

keep track of the current direction for players and monsters
function init_player() {
...
_player.platform = null;
_player.health_max = 50;
_player.health = _player.health_max;
_player.dir = 1;
...
}
_player.dir = 1;
...
}
