Hi,

I'm trying to execute the Listing 6.5 and 6.6 (MIDlet) from the SCMAD Exam Guide book. It is for a GameCanvas to display an animated Sprite according to its frame sequence.

In the following piece of code, I'm not clear what I should use for the man1.png. I created a small PNG file of a stick man in Paint. But am getting I/O access error. Complete listing for this exmaple is found in http://www.scmadbook.com/index.php/Code#Sprite_Sequence_MIDlet_.28Listing_6.6.29.

What is expected in the PNG file. Please help. I'm executing this in NetBeans v6.5 using the default emulator.



Regards,

Hi Jane,

We'll post the images referred in the book shortly on the website. Meanwhile, you should be able to use any PNG file (30px wide by 60px long). Make sure that it is in the location referred in the code (under the "res" folder).

Hi Sathya,

Thanks for your reply. The I/O access error was indeed due to a location and a filename issue. I was using lowercase .png; but image was stored under as .PNG. (duh...).

I created 4 pictures of 30 X 60 dimension and pasted them together using Paint. Was able to successfully run the program now, so that the four pictures were being displayed one after the other.

Thanks!,

You can get it from here as well.

Hi Ko Ko,

Executed the program with the original image that you sent. Was very happy to see the dancing man finally! Thank you very much.
(Only a slight change with regards to the image dimensions were required viz. sprite = new Sprite(manImage, 21, 43);)

Regards,
