I'm really new to pd. I'm learning at my university and I have to make a project using fiducial and ReacTIVision. In pd I want to put 4 or 5 pictures in different positions, the opacity would be 0% and if I move the Fiducial the picture which is closest to the fiducial will get filled (the opacity would change to 100% if the fiducial is nearby). I tried to make it with a text, but it only worked from the half and only on the x axis.
Could anyone help me with this, because I really don't know how to do it!
I saw that I should use conditional logic but I don't know how...
Thanks for your help and sorry for my bad english!(
