SOLVED: Assertion failure: Physics polygon separation

Hello,

at the moment I started to make my first game with Construct 2.

So I added some Objects and make some test.

But now when I start the game, following message appears:

[quote:30lbtt8s]

Assertion failure: Physics polygon separation resulted in no polys. Make sure all your collision masks for objects with the Physics behavior are valid and don't have any overlapping lines.

Can someone helps me where my failure is?

Hope to hear from someone sone,

What are the objects collision polygons like?

It's almost impossible to help from just a message. It helps greatly if a .capx with the error happening is supplied.

Hello,

thank you for the fast reply.

Here is the download file: https://www.dropbox.com/s/36jznl1aqh9cu ... .capx?dl=0

Some of the collision polygons on your objects are all over the place.

Primarily, you might want to take a moment to go through your objects and make sure all the collision polygons are as precise as possible and don't overlap.

If that doesn't clear the error, create a new .capx and copy and paste objects one at a time and test. At some point the error will through and you'll have you're culprit.

That helps me a lot... Thank you

I think it may just be the pieceleft, pieceright and umbrella. After fixing the collision polygons on those three, the .capx runs without an error.
