2D Opening and Closing Doors

in Technical Q&A

Hello.

I've only just bought AC and have (after a few hours of rewinding and forwarding) completed the brilliant 2D primer tutorial so please forgive me if these 2 questions seem a bit obvious.

Firstly, I would like to make a sprite disappear and re-appear with subsequent clicks. I can make a sprite 'vanish' by using the teleport function but just cant seem to figure out how I bring it back with the next click. I'm not even sure if teleport is the right way to do this.

Secondly, I would like to know the simplest way (if there is one) to use a key from the inventory on a door to make it open.

Thanks in advance.

    Welcome to the community, @CABJ.

    I would like to make a sprite disappear and re-appear with subsequent clicks. I can make a sprite 'vanish' by using the teleport function but just cant seem to figure out how I bring it back with the next click.

    If you're just looking to affect the sprite's visibility, you can use the Object: Visibility Action to show/hide it.

    You can precede these two Actions with an Object: Check visibility Action to work out if it's currently visible, and then hide it if so / show it if not. Otherwise, you'd have to look into using a Variable to keep track of its "is visible" state.

    I would like to know the simplest way (if there is one) to use a key from the inventory on a door to make it open.

    Inventory interactions can be defined at the bottom of a Hotspot's Inspector - which each interaction having a field for the Inventory item it should respond to.

    To have a door open, you'd probably want to run an animation of some kind using the Object: Animate Action, as well as update a Component variable attached to it that is used to keep track of it's "locked" state.

    This kind of game logic is covered in this section of AC's Interactivity tutorial series. A working example of a "key and lock" can also be found within the "Puzzle template: simple examples" package over on the Downloads page.

    Hi,

    Many thanks for your solution!!

    It seems to work a treat. This what I did following your instruction. Hopefully it doesn't need anything else. It does function in exactly the way I wanted so thanks again.

    I'll get onto the door issue after following the links you kindly supplied.
