Its possible to hit ignore and continue. However, the following error appears when trying to add a new object to a layout...

I can't reproduce this in either the standalone or Steam version. It launches just fine.

Normally this type of issue is caused by third party plugins which make breaking changes. Can you still reproduce if you remove all third party addons?

Removing custom plugins from C:\Users\%user%\AppData\Roaming\Construct2\plugins

Fixed the problem

I can report exact the same.

I still have plugins in the exporters\html5\plugins folder.

Plugins that were installed in C:\Users\%user%\AppData\Roaming\Construct2\plugins :

Magicam & noisejs

I deleted those two above, and then it worked normally.

Edit: noisejs is causing that error. delete the plugin and works fine

Yeah.. this 159 seems to get this.. Ah well, some cleanup time.

(EDIT)

FFS.. I even fully uninstalled 158.2 and deleted the entire exporters sub folder (where those extensions were) and this 159 still does this extremely unhelpful error message when trying to start.

Is there any way to *know* what directories this program goes to look foe extensions? As far as I remember I only put those extensions on that one location.

(edit2 .. the error message seems to be same as above)..

I'd really prefer to have either some verbosity on the loader so that I could know what's been loaded or robustness on the system. Ah well, at least I didn't have anything important going on.

Edit3: For clarity Win7-64, etc.. This PC has worked just fine on all eight previous versions I have so far installed (since R152).

My windows install is on A: drive and Construct2 is installed to H:construct2 directory

Edit: noisejs is causing that error. delete the plugin and works fine

Hey, don't pick on noisejs! <img src="smileys/smiley2.gif" border="0" align="middle" />

I use quite a number of custom plugins and removed only noisejs - it still happens.

The question here to me is why does this happen in r159? If you're making use of custom plugins in your project removing them is hardly a good fix.

Don't see any mention of breaking changes or adjustments to the SDK in the release notes.

<img src="smileys/smiley18.gif" border="0" align="middle" /> I *finally* found the problem.. The noisejs.addon was installed to A:roamaning-something and it prevented even 155 version to start properly.. I never asked anything to be installed there (I keep my C2 files at H-drive).. No wonder It took me some time to find.

So.. next thing to do is test the scirra.com/forum/improving-upon-the-performance_topic84725.html while I have this old version installed and then try installing 159 again.

Okay yeah, to be more specific:

It appears that some plugins are also put into the hidden folder

c:\users\name\appdata\roaming\construct 2(C being your windows drive and name your username)

resulting in them being duplicate and causing the error apparently. Remove the plugins from that folder and you're good to go again.

I guess it's something that happens or can happen when you install a plugin by dragging the .c2addon file into the C2 window, instead of copying it manually to the plugin folder.

EDIT: Caught the error specific to the perlinjs plugin. I indeed simply forgot to use unique ids for the expressions. <img src="smileys/smiley5.gif" border="0" align="middle" /> For some reason this didn't cause any errors in 158.2 (but it should have!). Sorry for the confusion, was entirely my fault. <img src="smileys/smiley18.gif" border="0" align="middle" />

I'll update the link in the plugin thread with a working version now...

Closing as an issue with third party plugins.
