Hello,
When I pass a numpy array to Vector2, builtins such as min, max, dir, list
comprehension break, yielding the error:
RuntimeWarning: tp_compare didn't return -1 or -2 for exception
print min(0,1)
Traceback (most recent call last):
File "bug.py", line 7, in <module>
print min(0,1)
TypeError: only length-1 arrays can be converted to Python scalars
Here's the code that causes the bug:
import pygame
import numpy as np
arr = np.array([1,1])
print min(0,1)
vector = pygame.math.Vector2(arr)
print min(0,1)
The first min works fine, but once a Vector2 has been initialised with an
array, the second one breaks. I can fix the code by changing the line to:
vector = pygame.math.Vector2(*arr)
However, I'm still confused as to how this happens. Does anyone else get the
same results?
pygame ver: '1.9.2rc1'
Python: 2.7.11
Best regards,
Tristan
