Here is tutorial made about it:

http://www.scirra.com/forum/quazis-tuts-part-1-the-2-armed-ik-solver_topic39035.html

It's made for CC but it can be used for C2.

I'm not positive but access to families was added after the editor was made. Much like behavior access from python.

It basically is done with a floodfill. You can get the algorithm off of Wikipedia.

I don't have any examples for CC but here are a few for C2 which can serve as a guide to do it in CC.

This is one way to do it where COL and ROW is the top left position to copy from.

local number COL=5

local number ROW=10

SmallArray: For each XY element

--- SmallArray: Set value at (SmallArray.CurX, SmallArray.CurY) to BigArray.At(COL+SmallArray.CurX, ROW+SmallArray.CurY)

Edit:

Too slow...

can't use an algorithm I've found online because of the way the event system works.Nonsense, I made a capx a while back that used those algorithms and was able to implement it in events just fine.

This formula will convert a percent (x) to dB:

20*log10(x/100)

Now I see the problem, it's a bug, spawn doesn't pick the new object.

The workaround would be to use the System->Create action instead of Sprite->Spawn. For the position use Sprite.ImagePointX(2) and Sprite.ImagePointY(2).

Not currently. The solution that others have used is export the project twice with webgl enabled and disabled.

You can do lines just as easy as points:

When an object is created it becomes the only instance of that type that is picked. Once it is no longer picked it cannot be picked until the next top level event.

Some more info:

The way I'd do it is create the 5 sprites in one event then position them in the next.

Construct 2 does not have per pixel collision detection as would be needed for this. If you build the image with smaller pieces like rotated/re-sized rectangles then that's one option.

That being said if you really need per pixel collision detection you can get something working with the canvas plugin with the rgbaAt() expression.

Here is a simple example:
