How to implement a destroyable wall in iPhone game development
<p>I'm pretty routined in writing iPhone applications with common UIViews.
To extend my skills, I wanted to write a simple 2D game where a player needs to break complex wall structure with limited shoots.</p>

<p>One shot should demage the wall, but not break through. A second shot at the same position would break through the wall.</p>

<p>No I ask myself how to handle such thing. I think drawing a shape wouldn't do the job since the wall should look damaged at the hit point.</p>

<p>I could draw the wall be setting single pixles. Then I could erase every set pixel in the impact area. But I think this would be very slow and memory consuming.</p>

<p>How to manage such things ?</p>
