Guys i am new to processing and I dont know how to do focusing in processing. I have 5 rect() and i want to control each rect() one at a time using cursor keys. So basically I need focusing here so when i control one rect() they rest are unfocused. I will use my LEFT and RIGHT cursor keys to move the rect() which i am able to do. But I want to use UP and DOWN cursor keys to do focusing. Can anyone help ?
