I see you are working with a lot of buttons, but in event 1, 2 and 3 you are not saying which button you mean when setting it enabled/disabled..

You should make a reference to the button, so the program knows which one to perform the action on..

I would highly recommend to use "Tint" effect for purpose such as this.

Using the "Tint" effect is probably far more cpu intensive then just changing a frame..

Is your animation set to speed 0?

Is there more than 1 sprite4?

Are there any other events that could be conflicting?

There should be no difference between the sprite having car-behaviour or not..

You could use system.wallclocktime for this It will keep counting even if the game is suspended.

Another option would be to use the third party system date time - plugin from the plugin section of this forum..

( this would still work if you close and re-open the game)

You will need to use local storage to save stuff to be able to compare correctly..

It's not a bug..

If both sprites are instances of eachother you can use the condition Sprite pick top/bottom

Otherwise you can do this by putting both sprites in a family and using that condition..

Third option is comparing the sprite.Zindex to pick the top or bottom one..

Should be pretty simple..

Give the photo's drag and drop behaviour and instance variables OldX and OldY

On drag and drop start

set OldX to object.x

set OldY to object.Y

And "On drag and drop drop" compare the OldX and OldY with object.x and object.y or Mouse/touch.x and Mouse/Touch.y and decide which actions to take accordingly..

I guess you could try something like this:

Create an "on destroyed"- event, add a sub-event to check if the destroying means it shouldn't appear anymore (for example if player kills it)

Push some values like x,y,health,speed, etcetera into an array..

Every tick check the coordinate values in the array to see if the object should be created or not

On created set all instance variables to the values in the array and remove the values from the array..

Why do you want to use an external file for this when all of your requirements can be done from within C2?

Destroy objects on start of layout and create them when needed..

If you want to store their values when you destroy them you could do this in a dictionary object or an array in an on destroyed event..

All you have to do then is making sure when created C2 knows which dictionary/array belongs to the object being created..

I guess:

increasing gravity would increase fallspeed..

increasing density would increase fallspeed..

decreasing linear damping would increase fallspeed..

Through the browser object you can get all the info you want..

Browser.Title

The current HTML document's title.

Browser.Domain

The current domain, e.g. scirra.com.

Browser.Hash

The string after the hash at the end of the URL, including the hash. For example, if the current URL is http://scirra.com/mygame/index.html#teapot, this returns #teapot.

Browser.PathName

The path relative to the domain in the URL. For example the path name of http://scirra.com/mygame/index.html#teapot is /mygame/index.html.

Browser.Protocol

The current protocol, usually either http: or https:.

Browser.QueryParam

Return a query string parameter by name. For example, if the URL ends with index.html?foo=bar&baz=wan, QueryParam("foo") returns bar and QueryParam("baz") returns wan.

Browser.QueryString

Return the full URL query string including the question mark. For example, if the URL ends with index.html?foo=bar&baz=wan, this returns ?foo=bar&baz=wan.

Browser.Referrer

Get the previous page that linked to this page, if any.

Browser.URL

Get the complete current URL in the browser address bar, including the protocol.

Very simple example:
