Calculating distance

Hello,
Was wondering what is the best module to be used in order to calculate the distance from the triangle to the ball.
Thank in advance.

1. Enable the create blobs array in the blob_filter module. That will create a variable that contains all the COG's of all the remaining blobs in the image.
2. Use the Calculate_Distance module and select the first 4 blob array entries (which are assumed to be object1 and object2's cogs).
3. Display the results stored in my_distance
Note that you can also use the VBScript module to create the variable from the following euclidean distance formula.
blobs = getArrayVariable("BLOBS")
... check that blobs is an array and has at least 4 values and then
dx = blobs(0) - blobs(2)
dy = blobs(1) - blobs(3)
my_distance = sqrt((dx*dx)+(dy*dy))
which should get you the same results at the Calculate_Distance module.
See attached robofile.
STeven.
