Error in simulator - nothing is drawn within the simulator window

[max2play]

Hi,

I set up everything according to your docs. Using a virtual machine with Debian Wheezy and Gnome.

This is the error message: user@develop: ~/Arbalet/arbapps$ python -m arbalet.apps.colors Exception in thread Thread-2: Traceback (most recent call last): File "/usr/lib/python2.7/threading.py", line 552, in __bootstrap_inner self.run() File "/usr/local/lib/python2.7/dist-packages/arbalet_core-3.0.0-py2.7.egg/arbalet/core/arbasim.py", line 64, in run self.display.fill(color.Color(pixel[0], pixel[1], pixel[2]), ValueError: invalid color argument

The simulator window opens and if I remove the line that produces the error at least the vertical and horizontal lines are drawn. But nothing else happend - tried other demos as well.

Any ideas?

Thanks, Stefan

Found that the value of "pixel" is not useable by the Color function of PyGame. Forcing conversion to integer for the Pixel values solves the problem in /usr/local/lib/python2.7/dist-packages/arbalet_core-3.0.0-py2.7.egg/arbalet/core/arbasim.py:

self.display.fill(color.Color(int(pixel[0]), int(pixel[1]), int(pixel[2])), Rect(w*self.cell_width, h*self.cell_height, self.cell_width, self.cell_height))

Maybe anyone else discovers the same problem - anyway NICE PROJECT!

Hope I could help you with my finding.

They are normally numpy ints, funny your pygame does not accept them. Could you give the output of python -c "import pygame; print(pygame.__version__)"?

Anyway a safe cast is worthy, would you mind commiting your changes and opening a pull request directly on the master branch?

PyGame version is "1.9.1release". Although the numbers of the pixel array look like ints, without the converions it does not work - I will create a pull request for the cast to integer.

I'm testing on 1.9.1release as well, it's strange. Anyway thanks for the bug report and patch!
