Super annoying sudden jerkiness in platform game. Tried everything!

[lachmandoo]

Hey guys,

I am still in the early days of my platform game and have hit an annoying problem, I just can't work out. I have made the first level with platforms and the main character. As you run across the screen the scrolling of the game seems to have sudden bits of jerkiness, always in the same spots. If you turn around and go back through the level it's fine no jerkiness but the first time through it's always there in the same spots.

I don't believe it's a memory problem, I have tried a whole range of settings and things but can't seem to get it to run smooth.

If anybody would like to help please let me know and I can send you the project file, I will be forever in your debt as this is driving me a little crazy!!

Cheers.

Ok re-drawing my level pieces at 1024x512 has fixed it up, all sweet!

Glad you figured it out

The iOS runtime will load textures into memory when they are about to be drawn to the screen. It does this because it tries to keep it's memory usage as low as possible. Loading all resources at the start of the level will just consume too much memory and the app would crash.

Having smaller resources (textures) makes loading them faster and you will not notice any slowdowns during gameplay.

I did the same thing with AWESOME Land, I grouped all my tiles into much bigger ones wherever I could, it improved performance drastically!

Tell me more, DistantJ - there is better performance by using 1024x1024 instead of 256x256 tiles?!? I'm curious...

Yes, I also I'm curious, I'm using textures from 256 * 256

I was using 512 * 512 and my game would crash a lot. After I brought it down to 256 * 256 no more crashing!
