032 : Check platform collisions
Balthazar:
Whenever the player collides with a platform, we want to record that the player is on a platform.
Balthazar:
We do this by initializing the _player.platform variable to false and then checking the platform to see if the player has collided with it. If the player has collided with the platform, then we set _player.platform to be true.
Balthazar:
This works because gravity is constantly pulling the character down onto the platform. The only time the player will **not** be colliding with a platform is when the player is in the middle of a jump.
script.js: Record the platform if the player collides with it.
function check_platform_collisions() {
_player.platform = false;
if (_player.y > _game.platform.y) {
_player.platform = true;
_player.y = _game.platform.y;
_player.velocity_y = 0;
}
}
_player.platform = false;
if (_player.y > _game.platform.y) {
_player.platform = true;
_player.y = _game.platform.y;
_player.velocity_y = 0;
}
}
Balthazar:
Make sure your player can jump around before continuing.
