3 months ago I assume that you are aware of the fact that you are trying to divide by zero along the axis-lines? This would make the resulting vectors infinitely long - which is a bit difficult to handle...
class BasicUsage(Scene):
def construct(self):
def func(pos):
if pos[0] != 0 and pos[1] != 0:
return 1/pos[0]*RIGHT + 1/pos[1]*UP
else:
return ORIGIN
self.add(ArrowVectorField(func))
Description of bug / unexpected behavior
I don't even know how i got here!
Expected behavior
Should generate a vector field
How to reproduce the issue
Add a 1/ to the lambda
Code for reproducing the problem
```py class BasicUsage(Scene): def construct(self): func = lambda pos: 1/pos[0]*RIGHT + 1/pos[1]*UP self.add(ArrowVectorField(func)) ```Logs
