I'm having issues with connection objects. I'm try to have a event where a value will set to 1 if a block is either on the top, bottom, left, or right side. I can't really get it work.

Here's the cap.

This looks fishy to me :

+ Block_Green: Y Equal to Block_Green.Y[/code:2kwxxfup]

When i remove it it says : connected 60, not connected 2.
Maybe these 2 not connected are the ones on the left and right of the chain?
It's lunch time, i'll investigate  a bit

Overlaps at offset would work good in this situation.

+ System: For each Block_Green
    + Block_Green: overlaps Green : offset (1,0)
    + System: OR
    + Block_Green: overlaps Green : offset (-1,0)
    + System: OR
    + Block_Green: overlaps Green : offset (0,1)
    + System: OR
    + Block_Green: overlaps Green : offset (0,-1)
    -> Block_Green: Set 'Connected' to 1

Okay, I'll try it.

My boxes or 48 by 48, so, wouldn't be 49 and -49 instead of one?

+ System: For each Block_Green
     + Block_Green: overlaps Green : offset (49,0)
     + System: OR
     + Block_Green: overlaps Green : offset (-49,0)
     + System: OR
     + Block_Green: overlaps Green : offset (0,1)
     + System: OR
     + Block_Green: overlaps Green : offset (0,-1)
     -> Block_Green: Set 'Connected' to 1

Use 1 if you want objects touching to be marked as connected. With 49 objects with a 48 pixel gap between them will be marked as connected.

Ah, so it offsets the collision boxes?
