  • If preview does not load, press F12 and check the browser console for any error messages. It's difficult to help without that information.

  • Is there any way to debug on these phones to identify the problem?

    Only Google can identify this kind of problem. As I said before, if you run in to a performance problem that only affects the APK and not the browser, please file an issue with Google at crbug.com with details about the device.

  • Yes, all functions are global. It's easy to check: just create a project, add a second event sheet, add a function, and see if you can call it in the other event sheet. You can. I noticed the manual entry does not specifically state that though, so I added a note to point that out.

    But no, being global does not mean it has to be checked every tick. Like triggers, they only run when they are called.

  • I think this could prove very complicated, since you could accidentally make thousands of expressions invalid in your project, if you did a find-replace that produced invalid syntax. There would have to be some way to prevent that, and that may in turn prove sufficiently limiting that the feature doesn't do what you want it to any more.

    Find-replace is also notoriously error prone - for example if you do a naive text-based find and replace for "text" with "label", and buried somewhere in thousands of events you have some dialog shown in game saying something like "In the right context we could...", that will also update to "In the right conlabel we could...". Now you've mangled a bunch of your game's dialogue in hard-to-find ways that will only show up after hours of playtesting. This is such a common problem that whenever I want to do find-replace myself in Construct's code, I actually just do a find, and manually update all the results so I don't end up making that type of mistake. So I would suggest a similar approach in Construct is wise - and you can already do it that way.

    For the most part, if you rename something in the editor, like an object name, it automatically updates all its references in the rest of the project. So it kind of exists in that form already.

  • Try Construct 3

    Develop games in your browser. Powerful, performant & highly capable.

  • I just checked and it seems to be working fine for me. Maybe check your Internet connection is working.

  • 700mb is a very large memory requirement for a mobile game. I would guess the app is crashing due to running out of memory. See Remember not to waste your memory.

  • We are unlikely to do this as it might draw new customers away from Construct 3. Construct 2 also uses commercial libraries that would make it difficult to open source.

  • You will need to use the postMessage() API to communicate with an iframe.

  • If you run in to a performance problem that only affects the APK and not the browser, please file an issue with Google at crbug.com with details about the device.

  • I'm not familiar with the Unity tool, but you can repeat mesh distorted images with Tiled Background.

  • The last few tests I did on a Pixel 3 appeared to run perfectly smoothly.

    Once again, I think the only good way to investigate this and find out what's really going on, is to file an issue at crbug.com with details about the specific device. Any jank/webview-specific performance issues are beyond our control, so only Google can investigate and fix them, and the more issues are filed about this, the higher they will prioritise it.

  • In 2020 the problem was repeated with another application and I solved it by deleting addons "even if the addon was not used in the project, it interfered with the app's performance!"

    None of the official addons should have any performance impact at all if you don't use them. If you can measure a performance overhead, please file an issue - we should be able to fix it.

    If a third-party addon has a lot of performance overhead, you'll need to contact the addon developer about it.

    I'd add that without rigorous measurements, it's easy to be completely misled by changes. For example if you change 2 things, one has a huge impact on performance, and the other has no impact at all, you can easily come to the false conclusion that both of those things improved performance, or that the wrong one improved performance. Since your post mentioned several things you did, it's not at all clear that the issue with addons you mentioned actually caused the problem. Further, even if a single addon does have some performance overhead due to a bug or something, "remove unused addons" is still not actually helpful advice: someone could remove a whole bunch of addons, but unless they remove that single offending addon, it won't make any difference. So to be useful advice, you should specify which. And if you specify which, we can investigate a potential performance problem and optimise it.

    I don't mean to pick on this poster specifically, but this kind of thing is repeatedly coming up in this thread, and often plays out across the rest of the community. Guesswork can result in poor advice, misleading conclusions, time wasted on meaningless changes, and create fear and uncertainty in the community as people say things like "but I thought unused addons had no performance impact?!" when they're probably actually right. If something really matters to performance, prove it: make two projects with a single change, make performance measurements in both, and compare the results. I would hazard a guess that of all the things people are saying here, 3 in 4 of them will make no difference at all. Measurements are the only things that matter, and you should only ever take performance advice seriously if it mentions measurements, and those measurements clearly correlate to a single change.

  • You need to contact the library developer about this. They need to make sure the library supports JavaScript Modules.

  • Will there be a Scripting API for containers, to be able to reference them? A sample use-case is setting all containers with an instance variable of the uid of the parent object, upon creation.

    It's not currently supported. It's best to log suggestions at construct3.ideas.aha.io so they don't get lost in the forum.

    FWIW, containers are pretty straightforward: because they always create and destroy together, all instances have the same IID (i.e. the same index in the instance lists), so you should already be able to figure out the container instances fairly easily.

    I've tried picking the objects by manual name search (runtime.objects["name"]), however it seems that the container objects are only later created after the "instancecreate" event. So, it's not possible to reference them on creation, unlike events.

    It's impossible to reference all container instances in a create event, due to the reasons I explained here.
