Is TouchesTest already using multitouch?

Some android devices do not support multitouch. I guess we should provide some sort of method to check this.

walzer@cocos2d-x.org 2011-02-01 18:44

Yep, we test multi-touch of uphone & iphone by TouchesTest, moving 2 or more white blockes synchronously.
As u c, this issue isn’t resolved yet.

Ok, I added the logic to support multiTouch. You can check my progress in this pull request:
https://github.com/cocos2d/cocos2d-x/pull/126

My issue now is that when I move to a different Scene, for instance TouchesTests or any other test, it gives me a SIGSEGV:

E/libEGL  (29587): call to OpenGL ES API with no current context (logged once per thread)
I/DEBUG   (   56): *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
I/DEBUG   (   56): Build fingerprint: 'google/passion/passion/mahimahi:2.2.1/FRG83D/75603:user/release-keys'
I/DEBUG   (   56): pid: 29587, tid: 29587  >>> org.cocos2dx.tests <<<
I/DEBUG   (   56): signal 11 (SIGSEGV), fault addr 0000004f
I/DEBUG   (   56):  r0 0000001f  r1 80808080  r2 80808080  r3 0000001f

Some important information:

a) The SIGSEGV is thrown in controller.cpp:43:
pScene = new PongScene(); break;

but when I add a log inside PongScene() it doesn’t show up :(

b)
I am NOT using queueEvent from GLSurfaceView. I will check if this can be the issue.

Macarse 2011-02-06 14:07

Yep. My issue is related with the fact that I am not using queueEvent BUT if we use queueEvent we lose some clicks (Never noticed you clicked on a button and nothing happened?).

I will try to make everything work without queueEvent(), if possible.

The optimization introduces a bug where the priority and Touch Mode will not get changed if the list is locked.
The most straight forward fix is to merge the pHandlersToAdd and pHandlersToRemove into a queue and process through all of them in the order they are received
