Compiled my first own player for 1076 and still got alot of weird errors.

I use alot of set scissor and get image in my app.

Spent the early morning by trying to find the problem with writing alot of various functions.

Then i found this pretty simple fix?

This is at the top of my app and it now always works right


There is simply something in the sync command that corrects something?

Possibly applying the SetVirtualResolution() command.

I've noticed image size "oddities" with getImage() if you don't set the resolution first.

I have found that after setting the SetOrientationAllowed command on android, you need to run sync() twice, to make sure it gets right. If not, then the first graphics will be in the wrong orientation, if the user started the app with the device in the wrong orientation, until 2 sync() are done in the main loop.

I guess TGC should add sync() to that command as a default?

No! its the sync command

If i dont do it so is the get image and set scissor screwed up ?

I only got black texture on my track before this.
And now it works all the time.

actually i found that you can sync anywhere in your program. You can also make some weird effects sync at the different locations.

Basically, you need to run sync() anytime you want to update the screen, after making changes to the position or information of objects. But beware that making more than one sync() between main loop runs, you will make overhead (slowdown of FPS). I guess you also tell the physics to update itself more than once every loop, making errors there.

Most AppGameKit programs I have seen are running around 45% CPU on a galaxy II, even if it's just a simple "Hello world!" loop. I guess the sync() command does ALLOT every time it's called. In simple games with little movements, I guess you only need to run sync() when something has moved, to save CPU/battery.

Yeah, I wasn't clear - I meant that the sync() command is applying the resolution changes from SetVirtualResolution().

Quote: "Basically, you need to run sync() anytime you want to update the screen"

..is a better way of putting it

Quite a lot of OpenGL calls are queued internally for efficiency, so it may be that a Sync() command is need to flush the queue.

Maybe tgc should make somethings clear with commads that forces an device to use other orientations and resolutions.
That you nead to use sync right after.

But i also found this command.

UpdateDeviceSize( w, h )

Description

If for any reason the device dimensions may have changed (e.g. a change in orientation rotates the viewspace to a new size) call this function to update the internal values.

But i havent tested it as iam on vacation and not home so much.
