Day 30 – First test on Ipod device

Well I showed you a video of where the  game was at on day 29 and now I have put the game on my ipod device for its first testing.


** Test your app on a device early and often!!!

I have read this plenty but did not get a chance to run on a device until now.

The main problem I ran into was the artifacts from the tilemap. I ran around the net all afternoon trying to solve the problem but all the hacks did not work. I even re-drew my tiles for spacing and margins but nothing worked.

To solve the problem I finally realized today I would change the way I move the camera from “float” to “int” and it solved the problem. Next issue was the background tilemap. it was still blinking and streaking, so to fix this I made the background fixed and not scrolling. The problem is the decimal required to have the background scroll at a different speed. You  need to move the map at whole number increments. This solutions means my background does not scroll but it still looks good to me so I think I am going to leave it.

The next thing I found was my sprite sheet was having a similar problem (for my player and objects) There would be little black lines every so often at the edge of the sprite frame. To solve this I need to have a space between the sprites on the sprite sheet. Solved the problem.

My last item I noticed I needed to fix was my map menu for selecting a level. The “dots” I used are too small so I am going to rethink the map.

As you can see testing on the actual device is very important. And I have been building the app to the device ever since. Rarely using the simulator.

Hope this convinces you to test your game on a device and I hope this posts helps you out.

    Hey Paul, great stuff so far, I’ve enjoyed watching the tutorials, I’m starting developing myself and I just find the documentation very scarce, the game looks sweet, I’m glad you were able to fix those issues.

    Best regards,

      Thank you Hector. My name is Jay, paulson just the company name.

      It has been great working on the iphone and I am learning a lot every day. I have completed 5 levels and added a few new kinds of enemies. I am working on my first “BOSS” now which is going to be fun.

      Keep checking in to see updates. Thanks again
