Suggestion about a photo hunt game

Hi all;

I want to make a photo hunt game(finding different between two similar pictures), what I have in my mind is to check rgb value of each pixel in pic1 and then compare it with the same pixel in pic2. But I’m not sure if this way is an appropriate way. Do you have any suggestion for a better way or it is good to continue my own way?

Thanks for your help :slight_smile:

My proposal is to have 1 image, and place some add ons (the other small textures) on the new image at your required places and place a collider on them.

Important, do not merge these into 1 texture. Then you can simply detect clicks on these textures to know when someone found a difference!
