reveal picture with line game(SOLVED)

Is there any way that construct 2 can do this kind off game.The player has to draw a line from point a to b and when the lines are closed or at the opposite end of the screen it should reveal a part off the picrure. See illustration below.

Well ... Possible , And easily ... I'm too busy working on my game for the competition , won't be able to help you ... Sorry !

I'll give you a hint : Take the horizontal line X and the vertical line Y

and make a square ( Width and Height ) with the distance between zero ( Or the the two starting point position variables ) and the two values ... The other part is all about blending ... Check out the blending example in the C2 examples libraries !

I'll give you a hint.

It takes three rectangles to fill in the black portion of your example.

Thank you for the hints.I managed to solve this little problem. Gotta love

Them global variables lol.

which competition, can i know the details so that i can submit mine to compete against you <img src="smileys/smiley17.gif" border="0" align="middle" />
