What are you using to get the information about the current date/time?

I don't understand..

You want to pin objects that don't exist on start of layout?

You can't perform actions on objects that don't exist..

You could make a global layer..

From the manual:

Global layers

Sometimes many layouts in a project have the same content on a particular layer, such as for interface or HUD overlaid on to the game. Changing this content then becomes a chore since changes must be repeated on every layout. Global layers are aimed at solving this problem.

If a layer's Global property is set to Yes, then every layer in the project with the same name is overridden by that layer. The initial objects, as well as its properties, are used instead of the other layer's own content and properties. Then changes can be made once to the original global layer, and the changes will be applied project-wide.

The layer with the Global property set to Yes is where all changes must be made from. On other layers in the project with the same name, the Global property will be read-only and display (yes, overridden) to indicate it is being substituted by a different layer. It will also not display in the layout view on other layouts, although its contents will appear when previewing the project.

You probably have an event setting your animation to some kind of "Idle" animation..

If you have an "idle" animation for each direction, set it on movement end or key released..

No, because its not run the browser

Thought I'd ask, because the manual clearly states:

Note exported projects, including the HTML5 export, cannot usually be run from disk. Your project must be uploaded to the web (for HTML5 export) or otherwise published before it will work.

There is the Ajax plugin to communicate with websites outside your game,

aso the browser object has execute javascript action..

If (a combination of) these don't work for you, writing your own plugin would probably be your best shot..

Have you uploaded your game?

There is not enough information here to base an answer upon..

Insert the browser object into your game and use the condition "is online"

So every tick the filechooser-object is on screen an image should be loaded?

Also, I'm quite sure the adress you are trying to load from doesn't exist..

filechooser.FileURLAt0)

should be enough, without "" around it

So you should probably replace the event "is on screen" with

Filechooser On changed

sprite set image from url: filechooser.FileURLAt0)

You say you have the generation done..

In what way do you generate the rooms?

Would it be possible to put the generated room in an array or save a tilemap asjson or..?

What is the issue with just adding the condition?
