I'd suggest that you create a very small, invisible block that is stuck to each image point on each pipe object. Testing to see if they're facing each other then just becomes a matter of testing whether a block is overlapping another block.

Nicely done... I like this solution as well.

Hello,

My name is Jim and though I am not new to the the Software Industry (software developer for 25 years) I am new to the game making part of it.

Since the beginning of November I have been comparing most the game development engines that are available: Game Maker, Stencyl, Game Salad, Unity 3D, Construct 2 and a few others. What I decided on was Construct 2. This choice was made by trying to implement a couple of interesting concepts (Physics Based) that I want to incorporate in a game or two in ALL of the engines that I tried. In some engines it was not possible, in others it was possible but only with coding - not that I am afraid of coding, but these were pretty simple ideas. I was not only easily able to accomplish all of my tests in Construct 2, but the performance was far better than the other engines as well.

The balance of ease of use and performance and future development path is by far the best. I even asked a couple of my friends who have been in the game industry for years and they agree with the development path that Construct 2 has decided upon.

Between a buddy of mine that is the Graphic Artist/Genius and myself we have a lot of interesting ideas that we are planning on implementing in Construct 2 games. Most of which will have a very different look and feel from the games that you see now and some that will look familiar.

I hope to learn from all of you the tricks of the trade and maybe contribute a few of my own.
