PsychoPy version 1.83
Im trying to develop a task where there will be a background grid of four rectangle boxes, an image will appear in one of the rectangular box. When i have set 4 images for each of the boxes and inserted condition for the experiment trials. As i said outo f 4 images, one image has to appear. So i marked $ with a target image file name in the opacity option. But in the runtime. It is showing an error, object has no attribute (setOpacity).
Please help me, Thank you in advance
