Hello, I have a super basic interaction to create but am struggling to get my head around how to achieve it in Unity. I have a Box and it can rotate when you click and move the mouse, I also need to be able to click an area on the Box and then have a dialogue box that tells you, user, they have selected the correct area. Basically like they are searching the box for a defect and have successfully found it. From what I have researched so far, I need to attach a camera ray to my camera so that it can hit a (collider?) attached to the box and then from there it can prompt the dialogue box? I have tried a few things but am still really confused how to make the camera ray do what I want and then make something appear on my UI to explain what they have found. Would anyone be able to help me with this or direct me to appropriate help?
