Toddler question

I know I shouldn’t be comparing. My little guy 15mo old. He says dada mama and claps, dance for the music do bye, play peeka boo, but he don’t point at things or when I say other words he doesn’t pay attention. Is this normal at this age? I saw a 13 month old saying many words and points stuff. How could I grab his attention? He throws his toys at me even while I’m sitting and talking with him. I don’t know how to handle it. Even if I ignore he constantly throwing stuff and damn it hurts a lot.
