I am making a RTS type game where you make armies/bases, and use them to destroy your enemies army/base. I am considering adding a video chat system(Not necessary, but in my opinion would be pretty cool). is there any way to get input from pc/mac camera if there is one plugged in?(also if possible the scripting for IOS/Android/Webplayer).
Yes indeed. You can access attached Web Cam devices. To read and study more about this, visit the scripting reference for Unity and search using the keyword “webcam”. You will find a variety of matching hits. I would start by reading about “WebCamDevice” and “WebCamTexture”.
