  • Go to line 32 and mention that the ball size is set here and can be changed.
  • Create a pre-processor block using right click | Preprocessor blocks | Create If / Else block
  • Use code completion to select SunPhone and change the code like this:
//#if SunPhone
        this.ballWidth = 24;        
        this.ballWidth = 16;
