Chapter 1. Introduction To Impact
Impact is a JavaScript game framework created by Dominic Szablewski. Impact takes advantage of the modern browser’s Canvas element in order to create high-performance 2D games on the Web and even mobile. One of the biggest advantages of using Impact is that it is easy to pick up, comes with very good code examples, has an active community, and has a very robust level editor called Weltmeister. The only barrier of entry is the licensing fee for the software, since it is not open source. After purchasing a license, you do get the full source code, the Weltmeister level editor, and free current major version updates (1.x). While there are other open source and free JavaScript game frameworks out there, Impact has an extra level of polish I haven’t seen with anything else so far.
Why Use Impact?
Perhaps one of the most appealing factors of buying Impact is the inclusion of a sample Objective-C project that allows you to compile your Web game into a native iOS app. This enables your game to take advantage of OpenGL for graphics and OpenAL for sound instead of the Canvas and Audio elements in the mobile Safari browser. This solution gives your game almost native-like performance on iOS, and it can be packaged up and sold in the Apple Store just like a native app.
