135 : Key
Balthazar:
Now that we have support for generic items, we have add different item types the behave differently.
Balthazar:
The first item is a key that can be used to unlock the goal.
Balthazar:
We have one key on each level that is used to unlock the goal. If the play does not have the key, they will not be able to enter the goal.

Balthazar:
adds and only allow the goal to work if the player has the key for this level
function check_goal_collisions() {
var level = _levels[_game.current_level];
var goal = level.goal;
if (collide(goal, _player)) {
if (collide(goal, _player) && level.player_has_key) {
start_level(goal.next_level);
}
}
if (collide(goal, _player)) {
if (collide(goal, _player) && level.player_has_key) {
start_level(goal.next_level);
}
}
Balthazar:
with this change, the goal won't work until you get the key.
Balthazar:
Unfortunately level 2 doesn't have a key, so you can't get to level 3 anymore.
