I always wanted to test out using SVN with Construct 2 projects as I save mine as a whole project folder instead of a single file archive. I tried once to amend the project settings and event sheets in the xml format and ran it. I'm able to open the project but unable to export.

Ashley: Is there some sort of hashing done to prevent amending the project files directly via xml?

If I can amend the files directly then source control would not be a problem as I can diff and merge.

Let's say if I activate a main group in an event, does all the sub-groups in the main group gets activated? If I had some of the sub-groups deactivated in the beginning and after deactivating the main group in one of the events, I reactivate the main group, will the sub-groups remain deactivated?

What I wanted to do is to propagate certain values on collision, something like a viral effect.

So the for each after the on collision condition would only affect those involved in the collision?

Crap. I posted another topic for this without digging longer. But seriously is there a way to differentiate between the 2 instances involved in the collision?

How do I compare 2 instances of same object when I need an action triggered performed on one of the instances based on one of the instance variables when they collide.

Switching between layouts would reset the layouts. It's like closing a layout and opening another. So the easy way out is to use layers instead of layout. The best method is to find a way to store all the states of the objects in your main game layout into a global instance or variable then loading the states when you switch back to the layout.

Is it also possible to store arrays into objects rather than variables?

How to retrieve the object type from the UID after storing?

How to iterate through the items in the array?

You should probably redo the events in terms of trigger-based rather then a while-not loop.

For example, you can set the text_start to be blinking at default as you did on your example, and only hide it when the key is pressed in another event.

Is it possible to amend the astar calculation based on the collision polygon instead of the image height and width?
