046 : Use collide for jumps
Balthazar:
But before we do that, now that we have this nifty collide() function, we can use it for our platform collisions as well.
Balthazar:
Note that collide() needs each object to have an origin_x and origin_y set. Platforms don't have that, so we'll need to add them.
function create_platform(x, y, width, height) {
var p = {};
p.x = x;
p.y = y;
p.width = width;
p.height = height;
p.origin_x = 0;
p.origin_y = 0;
return p;
}
p.origin_x = 0;
p.origin_y = 0;
return p;
}
Balthazar:
And with that change, we can switch the platform collision detection over to using collide().
function check_platform_collisions() {
_player.platform = false;
if (_player.y > _game.platform.y) {
if (collide(_game.platform, _player)) {
_player.platform = true;
_player.y = _game.platform.y;
_player.velocity_y = 0;
}
}
if (_player.y > _game.platform.y) {
if (collide(_game.platform, _player)) {
_player.platform = true;
_player.y = _game.platform.y;
_player.velocity_y = 0;
}
}
