Beta 4: Various bugs

[netninja]

1. Random numbers not random?
Problem:
Objects are placed in the same place each time when their positions are set 'randomly'.

Expected Output:
In MMF2 on windows the first frame will place the 20 objects randomly in the frame. If you go backwards and forwards between the two frames it will have different configurations each time.

Actual:
On the iPhone the objects will be created in random locations however once the frame is reloaded (going backwards and forwards between frames) or the application itself is restarted, the objects are always in the same positions.

On the iPhone simulator the same problem occurs. While the positions are different to the iPhone itself, they are still consistently in the same places on each run.

Even uninstalling the app and reinstalling it produces the same results.

Reason:
I suspect this might be because the random numbers aren't being generated properly? At first I thought that the loop wasn't running at all, but in my other application it might have been that it was generating '0' every time.

2. Background flashes white on frame/application startup.
I have set the background of the frame colour to black (0,0,0) however it flashes white for about 0.25 seconds when the application first launches, just after the Launch Image has displayed.

It should not flash white.


Thanks again for the quick fixes. I hope these issues can be fixed as quickly.

I will have a look at the random part but would be nice with a small example file We have many bugs to fix and it takes time to cook up an example file that has exactly the problem you describe. (no worries though)

2: It is a known issue. At the very first drawn frame there is no MMF frame loaded and I cannot access the frame color. It then loads and draws the first frame without the correct background color. Only on the second frame it will display the correct frame color.

Workaround: Set your window border color to the same as your first frame color:

I will try to see if I can fix this properly for the next beta.

I forgot to attach the .mfa, and I've added randomtest.mfa too which shows that the numbers generated are using the same seed each time.

Also:
3. The Application icons aren't high resolution on the iPhone 4 home screen.

Even though MMF allows you to edit the icon image at 114x114, it displays a scaled down version.

Here is a screenshot from my phone:

In green are high resolution icons (114x114) in red are the lower res ones which are upscaled (including ones generated by MMF at 57x57).

The randomiser was actually not randomised at all. It was always initialised to zero. This is corrected.

Thank you
