Obstacle in the way of making visual search task

[Tina]

I’m trying to build a visual search task in builder, but I’m constantly being received this error:

Blockquote

assert (3 >= len(verts.shape) >= 2) and (verts.shape[-1] == 2), (
f"Expected vertices to be coercible to a Nx2 or nxNx2 numpy array, not {verts.shape}"
)

This task consists of one hexagon stimulus as a target and 8 pentagons as distractor. I used Polygon component, and in its setting I chose regular polygon and I put 6 in Num.vetrices for the target stimulus and 5 for others. I don’t know exactly what goes wrong because everything seems right.

What it is asking for is a list of coordinate positions for where each vertice is. So for example putting in:
[[-0.5,1],[0.5,1],[1,0],[1,-0.5],[0.5,-1],[-0.5,-1],[-1,-0.5],[-1,0]]
These units are in cm.
Gives you this attempt at an octagon.

So you will have to do some testing to get your sizing and position correct. Remember that the format is [ [x1,y1],[x2,y2],…].
