there are number of ways you can make explosion with physics, but here is one extremely ugly way to do it (always love to construct when i'm drunk) <img src="smileys/smiley11.gif" border="0" align="middle"> .

you can even check for LOS to make it more "real"

exploding bomb that explodes

edit: change range to limit bomb "infuluence"/radius, left clikc for bomb, right click for TNT(left clikc on TNT to acivate it), play with values of power...

this was asked before (post), so I have opportunity to quote myself:

"you can create 'two' levels on one layout so that one player can't enter region ('level') of another, and with canvas plugin you can simulate second camera - to separate 'levels' and player visualy."

but this time with capx

unbound scrolling set to yes, you can restrict camera with sprites only or combine layout size and sprites that are separators...

edit: tilebackground doesn't work with canvas plugin when WebGL is ON !!!

quick/drty example

here is capx

use array to store radnom sequence in array (w5,h2), to store keys pressed, and to compare them

gvar - npress

on (sommething)

   +for "i" from 0 to 4 => set at x: loopindex, value round(radndom(1,6))

npress not=5

   + key "1" pressed => set at XY: (npress,2), value: 1

                         add 1 to npress

   + key "2" pressed => set at XY: (npress,2), value: 2

                         add 1 to npress

...

npress=5

   + compare at x,y - (comapre random sequence and key stored in array) = > do something...

    reset radnom sequence...

    set npress to 0

I know it's quick and ugly but it may give you general direction...

this is one way to do it

try this

edit: move with arrows

try this

here's another solution which counts line segments (not "infinite" lines)so line segments intersect not only because they are not parallel..

line-line intersection

edit: drag line end points

be more specific, which types of object intersects: line/line, line/circle, circle/circle, line/convex polygon intersection...

look at capx from my second post http://db.tt/YhpwdOYM - there you can use collision detection, sprite (on left/begining and right/end of group)are at same x position, and via 'global varariable' they move perfectly
