Well for mine case, when I redid the way the health system to update only once every few seconds later, compared to every tick, I noticed slight FPS gain. The worst however was with my infinite scrolling background, I couldn't get it to work on the ipad 1 or my old xperia.

It seems like Every tick with any Sprites related movement will cause an issue.

For appMobi, I tried exporting my tests as directcanvas enabled but it turns out black on both the Android devices I tested. It works without it but the performance is very bad. My friends who tested it on Nexus 7 and Note 2 said the performance was at best 20 to 30 ish with noticeable lags.

why is that? Is it something that will be fixed? Ludei's side?

Tested it with Cocoonjs, the performance is incredible! I managed to get a smoother fixed 17 FPS on the old machine.

Thanks a lot for the help!

On a side note, it seems Appmobi pales in comparison thus far. The directcanvas export didn't work for me. I haven't tested Phonegap though, but judging by what Cocoonjs did, I am happy to stick with it.

I tested it on a Xperia x10 which is pretty old, so I understand and expected the performance, but I was getting bad performance from nexus 7 and also samsung note 2 as well (had friends to test it).

Probably because they tested it using the Android browser

Thanks Ashley for the tips! After numerous testing, it seems it's partly my fault as I have Every Tick command for a lot of stuffs. I managed to get more FPS out of my older Android after tweaking some stuffs to evaluated only when necessary.

Hi guys, the game I am prototyping runs fine on most PCs and the latest Iphone, but once it's tested on Android device, the performance hit becomes significant.

Probably a very dump thing to ask, but using alot of Every tick is a bad idea for mobile games?

I am trying to do an endless scrolling background and it seems like making it scroll all the time is a very bad idea?

Currently tested it on a few android Devices and it seems I am getting an average of 30 fps, where compared to PC, I am getting 50-60. Is there something wrong I have done? If you are able, please do test out the game above, your help is much appreciated!

I am creating the game at 1280*720, would that be advisable or would it better to create it at half resolution?

You can just double click the sprite individually and change their origin in the image editor. It's the one on the bottom left of the editor, that looked like a crosshair.

That actually might just work!! Thanks! I will try that out later. I am doing it as single layout, something like a treadmill. Right now there's three big identical cards just switch places everytime one of the card is near the end.

I have thought of doing it to a very wide layout, would that actually be adviseable? It definitely would not be infinite scrolling anymore.

You could just copy paste the X value of each sprite. But I am guessing you would want to do it dynamically?

If so, it's best to use a placeholder that will cover the whole length of your health bar (it can be hidden at run time). Then you merely take the width of it and divide it by the number of health heart you want, then it will be the same distance

I guess that's the one I have no clue on. If the enemy were to stop suddenly, how would I recenter the camera and scrolling rate ?

Hi Guys,

I am trying to create a game similar to this.

I managed to get an infinite scrolling background working, but how do I create the illusion that the enemy is part of the background? I would like to be able to stop the scrolling from time to time and continue from there.

Here's what I have so far

Infinite scrolling
