I just got a new router. I set up LAN preview in C2 according to Ashley's guide. Everything worked fine; previewed in all browsers, previewed to my mobile.

Now...it isn't working. I haven't changed anything that I can think of. This is the error I'm getting:

[attachment=0:38fqbgll][/attachment:38fqbgll]

I am running C2 as an administrator. I've double checked this. I'm using r190 stable. I also tried a separate instal of r192 beta, same thing.

Any ideas where to start here?

I think this is one of those features that would be useful to more experienced users, but would cause a lot of confusion for newcomers. I imagine Ashley has forseen the onslaught of 'performance issues' and 'bug reports' that would inevitably arise from improper use of such a feature.

It's also quite possible that this would require some deep changes to the engine, given that, in its current state, textures are only unloaded at the end of a layout.

Still...I would like to see this. It would make expansive, single layout games possible in C2, even on mobiles. I see the recent addition of 'Reload Layout X/Y' as a sign that Ashley has some interest in facilitating this.

When you say you made a new project with more objects and it ran smoothly, are you talking about normal physics objects, or were you using r0j0hound's plugin?

Like so?

Physics are pretty brutal on mobile, any way you slice it.

I don't know how much code you've already done, but you might take a look at this amazing plugin by r0j0hound:

To me, it seems to run smoother than box2d. It also has some amazing features that box2d doesn't, like collision groups (these objects only collide with each other).

Also, spawning/destroying objects is hard on the engine if you handle too many in one tick, even if the action only happens occasionally.

I just tried a few, they are working for me. C2 can't currently export to the arcade though (you have to go back to r184 if you want to do that).

Did you try multiple browsers? Chrome or IE is preferred.

Thanks for putting this much thought into this. I'm trying to build a crt distortion stack that will scale from a desktop down to a mobile. Adding glow and noise to a scanline effect really sings, but my phone doesn't like it, especially glow.

It sounds like you are installing the x86 apk. Try the ARM one.

Do you have any webgl effects in your project? I've found that if I apply too many demanding effects, it can slow parts of the editor to a crawl, providing 'preview effects' is enabled.

Actually, it is a bit unclear in the manual. I had to do a little experiment to find out.

Basically, if you have BOTH high dpi support AND high quality scaling enabled, games will render at native resolution if the browser they run in is 'zoomed'.

For example, you can 'zoom' into a page in chrome or firefox, which will scale all the page elements up. I imagine that high-dpi devices generally have their browsers default to high zoom settings.

There should be a more technical explanation of this in the manual. It could be helpful/hurtful on normal devices as well, assuming a zoomed browser window.

Actually, just to clarify, you aren't talking about the actual C2 IDE are you? Doesn't matter whether you use the 64 or 32 bit version of C2; all that matters is the version of the node-webkit exporter.

You shouldn't. Just smoother gameplay.
