4k by 4k frame too big?

[Sumo]

I just want an opinion to see if a 4,000 by 4,000 frame in iOS would be too big? I'm making an RTS game and I was thinking that would be a decent size for a world, but idk if that would strain the iOS game. What do you think?

nevermind the map size.. an RTS would likely strain the iPhone.. there is a whole lot of stuff going on in a typical RTS game..

i was thinking really only updating the stuff near your screen to optimize it.

It's possible to build an rts for the iphone.
You would need to have well optimized code though.

The map size should be fine. As far as I know just the size the graphics used is where most scale problems would lie.

I'm building the world with tiles basically and then changing the actives as backdrops and deleting the actives, so that should help.

I've noticed that large maps are not the problem, but the # of actives are. I've done 18,000x640 on my latest free app without an issue, but I worked hard to keep the actives to under 400:

With just the normal world generated with all these trees, rocks, ores, etc im at 121 objects. That's with pasting the grass and water in the background. If I was looking at 400 objects max, thats decent so far. I'll try to optimize as much as possible.

Remember it's not just object count, keep an eye on your virtual memory as well, i think above 70mb may be pushing it.

I made a Minesweeper app once that could barely handle 400 x 400 frame size (granted, there were a lot of objects). Only real way to know is to make it and test it. If you can accomplish object-based actions with math, while it may be harder to code, it will pay off with lower memory usage.

[UrbanMonk]

Inefficient code, not size of the frame I guarantee.

Try pulling out the string objects and all other extensions except the active objects and you won't see any slow down.
