- Tiled displays your system fonts.
- Computers have different sets of fonts. Therefore, browsers never rely on system fonts
- Which means if you select a font in Tiled, it is quite unlikely it will render properly in WorkAdventure
To circumvent this problem, in your text object in Tiled, you can now add an additional property: `font-family`.
The `font-family` property can contain any "web-font" that can be loaded by your browser.
This allows us to use the "Press Start 2P" 8px font in text objects, which renders way better than the default "Sans serif" font of your browser.
So far, the scripting API was using events to communicate between WA and the iFrame.
But often, the scripting API might actually want to "ask" WA a question and wait for an answer.
We dealt with this by using 2 unrelated events (in a mostly painful way).
This commit adds a "queryWorkadventure" utility function in the iFrame API that allows us
to send a query, and to wait for an answer. The query and answer events have a unique ID to be
sure the answer matches the correct query.
On the WA side, a new `IframeListener.registerAnswerer` method can be used to register a possible answer.
Turning the "importsNotUsedAsValues" TS config value to "error".
This will require us to use `import type` instead of `import` when we are importing a value that is only used as a type (and therefore that is dropped by the Typescript compiler).
Why this change?
This is a requirement to be able to use Svelte in the future. See https://github.com/sveltejs/svelte-preprocess/issues/206#issuecomment-663193798
I honestly don't believe text objects look good on map, and in real maps, I think text should be written on tiles.
However, for a variety of use cases (like in test maps in the /maps/test directory, it can be useful to be
able to display some text easily on a map.
This PR adds the ability to display this text.
Note: the "font" support cannot work correctly, as Tiled is listing fonts from the local
system, and those fonts are not available in a browser.
