  • You could use the Scripting feature in order to use the javascript function that does so.

    Thanks!

    How can I fetch the image URI via a JavaScript call in this context though?

  • It's not! If it's red it's not associated. Just try adding a new Else and move on.

    I don't understand what you mean.

    I'm asking why the "Else"-case is red, given that it should be valid in that image.

  • Is it possible to convert an image accessible via URI to base64 without using plugins?

  • It's not associated at this point. It must have belonged elsewhere, and that IF was deleted. If you try to add Else to the len() IF, it will add one, in black.

    I'm not understanding your explanation.

    What do you mean by "It must have belonged elsewhere"?

    Based on the image that I provided the "Else"-condition should not be red, since it's a valid event structure.

  • the fact that it is red means it has been orphaned from the condition it was attached to. whatever that was has been deleted, so the else turns red to let you know it is not an else for anything at the moment. There is a condition above it but the else is not connected to it in any way except that the else is the next thing on the event sheet. delete the else, right click on the event above and add a new else if that one needs an else.

    I'm not following. Putting "Else" in its own condition following another condition has always been a valid way of using "Else".

    I don't understand how the "Else" in this case could be orphaned when it's related to the condition above?

  • I don't think it is connected to the event above

    How do you mean? It's placed right after the first event.

  • Why is "else" red in the attached image?

  • You would essentially create a third party editor when you set the state of the tilemap, use the Browser plug to download the json either Tilemap.TilesJSON, or Tilemap.AsJSON I'm not sure, then import that file into project files for use with Ajax during runtime when you set the texture.

    The json should have all the data you need to completely change an existing tilemap, aside from the image data.

    Yeah but I'm not asking how to change the Tilemap image data. I'm asking various questions related to the image size not changing when changing the Tilemap image.

  • I would say you probably need to take a look at using the json save state, and using it if you need to import stuff besides the texture.

    Not sure I'm following. How do you mean?

  • I've had a lot of problems with not being able to load Tilemap image URI's during runtime, and I've boiled it down to the Tilemap object's image size not adapting to newly-loaded images.

    To be more specific, while other objects types (Sprites, Backgrounds) adapt their image sizes to fit whatever image that is loaded in during runtime, the Tilemap object apparently demands that nothing exceeds the original image size.

    My questions are:

    • What happens if i load in an image that is smaller than the original image size? Will I just get a lot of blank tiles until the tile row wraps, or will the image size shrink to fit the new, smaller image?
    • What happens if I decide that I need more tile space, and increase the original image size to allow for larger images to be loaded in. Will the tilemap data become messed up, due to the tile row wrapping changing?
    • Is there any way to get around Tilemaps not being able to load in larger images during runtime?

    Thanks in advance.

  • "Executed", not "excluded". Because that's how Construct works. All events are executed on every tick, unless they are triggers or functions.

    Sorry, I misread.

    I expect them to be executed on every loop, yeah, so that's fine by me.

    It still may require 1-2 ticks to be fetched, or maybe even longer on a slower machine. So you should not start checking JSON keys until it finished loading!

    Try this code: 

    > JSON has key "maps.test" -> Browser Log "HAS key, "&tickcount
Else -> Browser Log "NO key, "&tickcount

    Open browser console and check the messages. You will probably see a couple of "NO key" before "HAS key" appear.

    I actually can't get that to work at all:

    I've tried with single quotes, double quotes as well as loading the data from a separate JSON-file, but this always returns "no test".

    JSON.CurrentKey works only inside "JSON For Each" loop. If you need to get current path outside the loop, use JSON.path expression.

    Yes, I'm doing this as part of iterating through a foreach-loop.

  • If the events are at root level, they are executed on every tick.

    Why are they excluded?

    And if you are getting JSON data from a file or Internet, then it may not be ready during the first couple of ticks. And that's why the Else part is triggered.

    It's all local, so nothing is fetched remotely. All I'm doing is loading in a local JSON file that is embedded with the project.

    The reason why I posted this topic is because I'd like to understand how Construct loops through JSON. As far as I can tell, this information doesn't seem to be available anywhere.

    I keep running into strange scenarios like the one outlined in this thread, as well as a new one that I encountered just now where:

    Will not fire at all, but:

    Will set the global variable "debugger" to "background".

    The fact that you can't really troubleshoot JSON with breakpoints makes the whole thing challenging:

    Is there no information anywhere on how Construct loops through JSON objects?
